Remarks

The Dropbox class provides a simple interface to working with Dropbox. Capabilities include uploading and downloading files, strong encryption support, creating folders, moving and copying resources, and more.

Authentication

This class requires authentication via OAuth 2.0. First, perform OAuth authentication using the OAuth property to set the appropriate fields for the chosen OAuthClientProfile and OAuthGrantType.

The class has the following defaults:

Authorization Server URL "https://www.dropbox.com/oauth2/authorize"
Token Server URL "https://api.dropboxapi.com/oauth2/token"

Below is a brief description of the different OAuthClientProfile and OAuthGrantType values that are supported by this class. For a more in-depth description of what needs to be set, refer to the service documentation.

Application Profile

This profile encompasses the most basic grant types that OAuth supports. When this profile is set, all the requests and response handling is done by the class. Depending on the grant type, this may involve launching a browser so a user can login to authenticate with a authorization server. It may also involve starting an embedded web server to receive a response from a redirect.

To start the authentication and authorization process, the Authorize method should be called. If the authorization and authentication was successful, then the OAuthAccessToken property will be populated. Additionally, if a refresh token was provided the OAuthRefreshToken property will be populated as well. These values of the fields are for informational purposes. The class will also cache these tokens along with when the OAuthAccessToken will be expired. When a method that makes requests to the service provider is called or the Authorize method is called the class will automatically check to see if the access token is expired. If it is, it will then automatically try to get a new OAuthAccessToken. If the Authorize method was not used and user interaction would be required, the class will throw an error which can be caught. When user interaction is needed depends on what grant type is set in the OAuthGrantType property. To force the component to only check the access token when the Authorize method is called, the OAuthAutomaticRefresh configuration setting can be set to false.

A brief description of the supported values for the OAuthGrantType property are below. For more information, see the service documentation.

Authorization Code

When using the Authorization Code grant type, the class will use an authorization code to get an access token. For this OAuthGrantType the class expects a OAuthClientId, OAuthClientSecret, OAuthServerAuthURL, and OAuthServerTokenURL to be set. When the Authorize method is called, the component will start the embedded web server and launch the browser so the user can authorize the application. Once the user authorizes, the service provider will redirect them to the embedded web server and the class will parse the authorization code, setting the OAuthAuthorizationCode property, from the redirect. Immediately, the class will make a request to the token server to exchange the authorization code for an access token. The token server will return an access token and possibly a refresh token. If the OAuthRefreshToken property is set, or a refresh token is cached, then the class will not launch the browser and use the refresh token in its request to the token server instead of an authorization code.

Example: Dropbox dropbox = new Dropbox(); dropbox.OAuth.ClientProfile = CloudOAuthClientProfiles.cocpApplication; dropbox.OAuth.GrantType = OAuthSettingsGrantTypes.cogtAuthorizationCode; dropbox.OAuth.ClientId = CLIENT_ID; dropbox.OAuth.ClientSecret = CLIENT_SECRET; dropbox.Config("OAuthWebServerPort=PORT"); // http://localhost:PORT needs to be a registered redirect URL for the app dropbox.Authorize();

Implicit

Note: This grant type is considered insecure and should only be used when necessary.

When using the Implicit grant type, the class will request the authorization server to get an access token. For this OAuthGrantType the class expects a OAuthClientId, OAuthClientSecret, and OAuthServerAuthURL to be set. When the Authorize method is called, the component will start the embedded web server and launch the browser so the user can authorize the application. Once the user authorizes, the service provider will redirect them to the embedded web server and the class will parse the access token from the redirect.

A disadvantage of the grant type is that can not use a refresh token to silently get a new access token. Most service providers offer a way to silently get a new access token. See the service documentation for specifics. This means the class will not be able to automatically get a fresh token once it expires.

Web Profile

This profile is similar to setting the class to the Application profile and Authorization Code grant type except the class will not launch the browser. It is typically used in situations where there is a back-end that is supporting some front end. This profile expects that OAuthClientId, OAuthClientSecret, OAuthServerAuthURL, OAuthServerTokenURL, and the OAuthReturnURL properties to be set. Before calling the Authorize method, the OAuthWebAuthURL property should be queried to get a URL. This URL should be used to redirect the user to the authorization page for the service provider. The redirect_uri parameter of this URL is mapped to the OAuthReturnURL property. The OAuthReturnURL property should be set to some web server that will parse the authorization code out of the query parameter from the redirect. Once the authorization code is parsed, it should be passed back to the server where it is then set to the OAuthAuthorizationCode property. Once that is set, the Authorize method can be called to exchange the authorization code for an access token and refresh token if provided. The class will then cache these values like normal and use them to make requests. If the OAuthRefreshToken field is set, or a refresh token is cached, then the Authorize method can immediately be called to make a request to the token server to get a new access token.

External OAuth Support

For complex profiles or grant types, or for more control of the flow, it is possible to perform OAuth authentication using the OAuth class or a separate process. Once complete you should have an authorization string which looks like:
Bearer ACCESS_TOKEN_VALUE

Assign this value to the Authorization property before attempting any operations. Setting the Authorization property will cause the class to ignore the values set in the OAuth property.

For Example: Oauth oauth = new Oauth(); oauth.GrantType = OauthGrantTypes.ogtAuthorizationCode; oauth.ClientId = "CLIENT_ID"; oauth.ClientSecret = "CLIENT_SECRET"; oauth.ServerAuthURL = "https://www.dropbox.com/oauth2/authorize"; oauth.ServerTokenURL = "https://api.dropboxapi.com/oauth2/token"; oauth.WebServerPort = PORT; // http://localhost:PORT needs to be a registered redirect URL for the app dropbox.Authorization = oauth.GetAuthorization(); Consult the documentation for the service for more information about supported scope values and more details on OAuth authentication.

Addressing Resources

Dropbox typically allows resources to be addressed in multiple ways:

  • Using a path (e.g., /path/to/resource.txt).
  • Using a resource Id (e.g, id:xxxxx).
  • Using an Id-based relative path (e.g., id:xxxxx/relative/path/test.txt, where the Id is that of a folder resource).
  • For certain methods, using a revision Id (e.g., rev:xxxxx).
The documentation for this class's methods will always note which of the above options are acceptable for each applicable method parameter.

Listing Resources

ListResources lists resources within the specified folder. Calling this method will fire the ResourceList event once for each resource, and will also populate the Resources properties.

If there are still more resources available to list when this method returns, the ResourceMarker property will be populated. Continue to call this method until ResourceMarker is empty to accumulate all pages of results in the Resources properties. Alternatively, the AccumulatePages configuration setting can be disabled to clear the Resources properties every time a page of results is returned. // ResourceList event handler. dropbox.OnResourceList += (s, e) => { Console.WriteLine(e.Name); }; do { dropbox.ListResources("/work_files/serious_business/cats"); for (int i = 0; i < dropbox.Resources.Count; i++) { // Process resources here. } } while (!string.IsNullOrEmpty(dropbox.ResourceMarker));

Downloading Files

The DownloadFile method downloads file resources.

If LocalFile is set, the file will be saved to the specified location; otherwise, the file data will be held by ResourceData.

To download and decrypt an encrypted file, set EncryptionAlgorithm and EncryptionPassword before calling this method.

Download Notes

In the simplest use-case, downloading a file looks like this: dropbox.LocalFile = "../MyFile.zip"; dropbox.DownloadFile(dropbox.Resources[0].Id);

Resuming Downloads

The class also supports resuming failed downloads by using the StartByte property. If a download is interrupted, set StartByte to the appropriate offset before calling this method to resume the download. string downloadFile = "../MyFile.zip"; dropbox.LocalFile = downloadFile; dropbox.DownloadFile(dropbox.Resources[0].Id); //The transfer is interrupted and DownloadFile() above fails. Later, resume the download: //Get the size of the partially downloaded file dropbox.StartByte = new FileInfo(downloadFile).Length; dropbox.DownloadFile(dropbox.Resources[0].Id);

Resuming Encrypted File Downloads

Resuming encrypted file downloads is only supported when LocalFile was set in the initial download attempt.

If LocalFile is set when beginning an encrypted download, the class creates a temporary file in TempPath to hold the encrypted data until the download is complete. If the download is interrupted, DownloadTempFile will be populated with the path of the temporary file that holds the partial data.

To resume, DownloadTempFile must be populated, along with StartByte, to allow the remainder of the encrypted data to be downloaded. Once the encrypted data is downloaded it will be decrypted and written to LocalFile. dropbox.LocalFile = "../MyFile.zip"; dropbox.EncryptionPassword = "password"; dropbox.DownloadFile(dropbox.Resources[0].Id); //The transfer is interrupted and DownloadFile() above fails. Later, resume the download: //Get the size of the partially download temp file dropbox.StartByte = new FileInfo(dropbox.Config("DownloadTempFile")).Length; dropbox.DownloadFile(dropbox.Resources[0].Id);

Uploading Files

The UploadFile method uploads new file resources.

If LocalFile is set the file will be uploaded from the specified path. If LocalFile is not set the data in ResourceData will be used.

To encrypt the file before uploading it, set EncryptionAlgorithm and EncryptionPassword.

Upload Notes

Dropbox offers two ways to upload a file. For smaller files a simple upload option is provided to upload data in one request. This is the default option. For larger files, uploads can be fragmented into multiple pieces, allowing resuming of uploads that may be interrupted.

Simple

By default the class uses the simple upload mechanism. dropbox.LocalFile = "../MyFile.zip"; dropbox.UploadFile("/MyFile.zip");

Resumable

To enable resumable uploads set UseResumableUpload to true. This is recommended for large files. The class will automatically fragment the specified file into smaller pieces and upload each individually. FragmentSize may be set to specify the size of the fragment if desired. The default fragment size is 10 MB.

When UseResumableUpload is set to true and UploadFile is called, a resumable upload session is started by the class. UploadSessionId is populated with a resumable upload session Id identifying the session (this value may be needed for additional operations if the upload does not complete normally).

During a resumable upload, the FragmentComplete event fires after each fragment is uploaded to indicate overall progress. The class also updates StartByte as necessary to indicate the current offset in the file.

If the upload is interrupted for any reason, resuming it is easy. First, verify that UploadSessionId and StartByte are populated (if the same instance of the class is used, they should already be populated, and no special action should be needed). Then call UploadFile again to resume the upload at the specified StartByte offset.

Note that if the upload is not resumed after some time the upload session will expire. dropbox.LocalFile = "../MyFile.zip"; dropbox.UploadFile("MyFile.zip"); //The transfer is interrupted and UploadFile() above fails. Later, resume the download. //Using the same instance StartByte and ResumeURL are already populated from the previous //upload attempt. dropbox.UploadFile("MyFile.zip");

Additional Functionality

To use a security key, the necessary data must first be collected using the CERTMGR class. The ListStoreCertificates method may be called after setting CertStoreType to cstPKCS11, CertStorePassword to the PIN, and CertStore to the full path of the PKCS#11 DLL. The certificate information returned in the CertList event's CertEncoded parameter may be saved for later use.

When using a certificate, pass the previously saved security key information as the SSLAcceptServerCertStore and set SSLAcceptServerCertStorePassword to the PIN.

Code Example. SSH Authentication with Security Key: certmgr.CertStoreType = CertStoreTypes.cstPKCS11; certmgr.OnCertList += (s, e) => { secKeyBlob = e.CertEncoded; }; certmgr.CertStore = @"C:\Program Files\OpenSC Project\OpenSC\pkcs11\opensc-pkcs11.dll"; certmgr.CertStorePassword = "123456"; //PIN certmgr.ListStoreCertificates(); sftp.SSHCert = new Certificate(CertStoreTypes.cstPKCS11, secKeyBlob, "123456", "*"); sftp.SSHUser = "test"; sftp.SSHLogon("myhost", 22);

22 (cstBCFKSBlob)The certificate store is a string (binary or Base64-encoded) representing a certificate store in BCFKS (Bouncy Castle FIPS Key Store) format.

Note: This store type is only available in Java and .NET.

23 (cstPKCS11)The certificate is present on a physical security key accessible via a PKCS#11 interface.

To use a security key, the necessary data must first be collected using the CERTMGR class. The ListStoreCertificates method may be called after setting CertStoreType to cstPKCS11, CertStorePassword to the PIN, and CertStore to the full path of the PKCS#11 DLL. The certificate information returned in the CertList event's CertEncoded parameter may be saved for later use.

When using a certificate, pass the previously saved security key information as the SSLServerCertStore and set SSLServerCertStorePassword to the PIN.

Code Example. SSH Authentication with Security Key: certmgr.CertStoreType = CertStoreTypes.cstPKCS11; certmgr.OnCertList += (s, e) => { secKeyBlob = e.CertEncoded; }; certmgr.CertStore = @"C:\Program Files\OpenSC Project\OpenSC\pkcs11\opensc-pkcs11.dll"; certmgr.CertStorePassword = "123456"; //PIN certmgr.ListStoreCertificates(); sftp.SSHCert = new Certificate(CertStoreTypes.cstPKCS11, secKeyBlob, "123456", "*"); sftp.SSHUser = "test"; sftp.SSHLogon("myhost", 22);

99 (cstAuto)The store type is automatically detected from the input data. This setting may be used with both public and private keys and can detect any of the supported formats automatically.

Timeout Property (CloudStorage_Dropbox Class)

The timeout for the class.

Object Oriented Interface

public function getTimeout();
public function setTimeout($value);

Procedural Interface

cloudstorage_dropbox_get($res, 173 );
cloudstorage_dropbox_set($res, 173, $value );

Default Value

60

Remarks

If the Timeout property is set to 0, all operations will run uninterrupted until successful completion or an error condition is encountered.

If Timeout is set to a positive value, the class will wait for the operation to complete before returning control.

The class will use DoEvents to enter an efficient wait loop during any potential waiting period, making sure that all system events are processed immediately as they arrive. This ensures that the host application does not freeze and remains responsive.

If Timeout expires, and the operation is not yet complete, the class fails with an error.

Note: By default, all timeouts are inactivity timeouts, that is, the timeout period is extended by Timeout seconds when any amount of data is successfully sent or received.

The default value for the Timeout property is 60 seconds.

Data Type

Integer

UploadSessionId Property (CloudStorage_Dropbox Class)

The Id of the resumable upload session.

Object Oriented Interface

Remarks

This method is used to add a query parameter to the QueryParams properties. Name specifies the name of the parameter, and Value specifies the value of the parameter.

All specified Values will be URL encoded by the class automatically. Consult the service documentation for details on the available parameters.

Authorize Method (CloudStorage_Dropbox Class)

Get the authorization string required to access the protected resource.

Object Oriented Interface

public function doAuthorize();

Procedural Interface

cloudstorage_dropbox_do_authorize($res);

Remarks

This method is used to get an access token that is required to access the protected resource. The method will act differently based on what is set in the OAuthClientProfile property and the OAuthGrantType property. This method is not to be used in conjunction with the Authorization property. It should instead be used when setting the OAuth property.

For more information, see the introduction section.

CalcAuthorization Method (CloudStorage_Dropbox Class)

Calculates the Authorization header based on provided credentials.

Object Oriented Interface

public function doCalcAuthorization();

Procedural Interface

cloudstorage_dropbox_do_calcauthorization($res);

Remarks

This method calculates the Authorization value using the values provided in AuthScheme, User and Password.

In most cases this method does not need to be called. The class will automatically calculate any required authorization values when a method is called such as Get or Post.

This method may be useful in cases where the Authorization value needs to be calculated prior to sending a request.

Config Method (CloudStorage_Dropbox Class)

Sets or retrieves a configuration setting.

Object Oriented Interface

public function doConfig($configurationstring);

Procedural Interface

cloudstorage_dropbox_do_config($res, $configurationstring);

Remarks

Config is a generic method available in every class. It is used to set and retrieve configuration settings for the class.

These settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the class, access to these internal properties is provided through the Config method.

To set a configuration setting named PROPERTY, you must call Config("PROPERTY=VALUE"), where VALUE is the value of the setting expressed as a string. For boolean values, use the strings "True", "False", "0", "1", "Yes", or "No" (case does not matter).

To read (query) the value of a configuration setting, you must call Config("PROPERTY"). The value will be returned as a string.

CopyResource Method (CloudStorage_Dropbox Class)

Copies a resource.

Object Oriented Interface

public function doCopyResource($fromresource, $toresourcepath);

Procedural Interface

cloudstorage_dropbox_do_copyresource($res, $fromresource, $toresourcepath);

Remarks

This method copies the resource FromResource to a new path ToResourcePath, and returns the Id of the newly-copied resource.

FromResource must be a path, an Id-based relative path, or a resource Id. ToResourcePath must be a path or an Id-based relative path (it must always end with the desired name of the file/folder resource being copied).

The AllowCopySharedFolders configuration setting must be enabled before calling this method in order to copy shared resources.

The RenameIfExists configuration setting may be enabled before calling this method to have the server automatically resolve naming conflicts.

CreateFolder Method (CloudStorage_Dropbox Class)

Creates a new folder resource.

Object Oriented Interface

public function doCreateFolder($newfolderpath);

Procedural Interface

cloudstorage_dropbox_do_createfolder($res, $newfolderpath);

Remarks

This method creates a new folder resource at the path NewFolderPath, and returns the Id of the newly-created folder resource.

NewFolderPath must be a folder path, or an Id-based relative folder path.

The RenameIfExists configuration setting may be enabled before calling this method to have the server automatically resolve naming conflicts.

CreateLink Method (CloudStorage_Dropbox Class)

Creates a shared link for a resource.

Object Oriented Interface

public function doCreateLink($resource);

Procedural Interface

cloudstorage_dropbox_do_createlink($res, $resource);

Remarks

This method creates a shared link for the resource specified by Resource and returns it.

Resource must be a path, an Id-based relative path, or a resource Id.

The CreateLinkExpiration, CreateLinkVisibility, and CreateLinkPassword configuration settings can be used to customize the settings used to create the shared link. // Create a password-protected shared link for the given file. dropbox.Config("CreateLinkPassword=password"); string sharingUrl = dropbox.CreateLink("/work_stuff/serious_business/best_cat_pictures.zip");

DeleteResource Method (CloudStorage_Dropbox Class)

Deletes a resource.

Object Oriented Interface

public function doDeleteResource($resource);

Procedural Interface

cloudstorage_dropbox_do_deleteresource($res, $resource);

Remarks

This method deletes the resource specified by Resource.

Resource must be a path, an Id-based relative path, or a resource Id.

When deleting file resources, the IfRevision configuration setting can be set to a revision Id before calling this method. This will ensure that the server only deletes the file resource if its latest revision Id matches the one provided.

For Dropbox Business accounts, the PermanentlyDelete configuration setting can be enabled to delete resources permanently.

DownloadFile Method (CloudStorage_Dropbox Class)

Downloads a file resource.

Object Oriented Interface

public function doDownloadFile($resource);

Procedural Interface

cloudstorage_dropbox_do_downloadfile($res, $resource);

Remarks

This method downloads the file resource specified by Resource. If the AllowFolderDownloads configuration setting is enabled, it can also be used to download a folder resource as a ZIP file.

Resource must be a path, an Id-based relative path, a resource Id, or (for file resources only) a revision Id.

For file resources, the DownloadType property can be used to control whether this method downloads the file contents (default), a file preview, or a file thumbnail. The latter two options are only available for certain file types; refer to DownloadType for more information.

Note that certain file resources are "export-only"; when downloading such a file resource to a LocalFile, the class will append the file extension of export file format (if the name of the given LocalFile does not already end with said extension). Refer to the ResourceExportExtension property for more information.

If LocalFile is set, the file will be saved to the specified location; otherwise, the file data will be held by ResourceData.

To download and decrypt an encrypted file, set EncryptionAlgorithm and EncryptionPassword before calling this method.

Download Notes

In the simplest use-case, downloading a file looks like this: dropbox.LocalFile = "../MyFile.zip"; dropbox.DownloadFile(dropbox.Resources[0].Id);

Resuming Downloads

The class also supports resuming failed downloads by using the StartByte property. If a download is interrupted, set StartByte to the appropriate offset before calling this method to resume the download. string downloadFile = "../MyFile.zip"; dropbox.LocalFile = downloadFile; dropbox.DownloadFile(dropbox.Resources[0].Id); //The transfer is interrupted and DownloadFile() above fails. Later, resume the download: //Get the size of the partially downloaded file dropbox.StartByte = new FileInfo(downloadFile).Length; dropbox.DownloadFile(dropbox.Resources[0].Id);

Resuming Encrypted File Downloads

Resuming encrypted file downloads is only supported when LocalFile was set in the initial download attempt.

If LocalFile is set when beginning an encrypted download, the class creates a temporary file in TempPath to hold the encrypted data until the download is complete. If the download is interrupted, DownloadTempFile will be populated with the path of the temporary file that holds the partial data.

To resume, DownloadTempFile must be populated, along with StartByte, to allow the remainder of the encrypted data to be downloaded. Once the encrypted data is downloaded it will be decrypted and written to LocalFile. dropbox.LocalFile = "../MyFile.zip"; dropbox.EncryptionPassword = "password"; dropbox.DownloadFile(dropbox.Resources[0].Id); //The transfer is interrupted and DownloadFile() above fails. Later, resume the download: //Get the size of the partially download temp file dropbox.StartByte = new FileInfo(dropbox.Config("DownloadTempFile")).Length; dropbox.DownloadFile(dropbox.Resources[0].Id);

GetAccountInfo Method (CloudStorage_Dropbox Class)

Gets information about the current user's account and space usage.

Object Oriented Interface

public function doGetAccountInfo();

Procedural Interface

cloudstorage_dropbox_do_getaccountinfo($res);

Remarks

This method gets information about the current user's account and space usage, populating the Account object property's properties. This method will also populate the following configuration settings, if necessary:

GetCurrentChangeMarker Method (CloudStorage_Dropbox Class)

Gets the most current change marker.

Object Oriented Interface

public function doGetCurrentChangeMarker($folderresource);

Procedural Interface

cloudstorage_dropbox_do_getcurrentchangemarker($res, $folderresource);

Remarks

This method populates NextChangeMarker with the most current change marker available. Like ListChanges, it may be limited to only changes within a certain FolderResource; and is sensitive to the IncludeDeleted, IncludeMounted, MaxResults, and RecurseSubfolders configuration settings.

FolderResource must be a folder path, an Id-based relative folder path, a folder resource Id, or empty string (the root folder).

Refer to ListChanges for more information.

GetResourceInfo Method (CloudStorage_Dropbox Class)

Gets information about a specific resource.

Object Oriented Interface

public function doGetResourceInfo($resource);

Procedural Interface

cloudstorage_dropbox_do_getresourceinfo($res, $resource);

Remarks

This method gets information about the resource specified by Resource.

Resource must be a path, an Id-based relative path, a resource Id, or (for file resources) a revision Id. Empty string (the root folder) is not supported.

Calling this method will fire the ResourceList event, and will populate the Resources properties with a single item (clearing any previously-held items in the process).

Interrupt Method (CloudStorage_Dropbox Class)

This method interrupts the current method.

Object Oriented Interface

public function doInterrupt();

Procedural Interface

cloudstorage_dropbox_do_interrupt($res);

Remarks

If there is no method in progress, Interrupt simply returns, doing nothing.

ListChanges Method (CloudStorage_Dropbox Class)

Lists changes to resources.

Object Oriented Interface

public function doListChanges($folderresource);

Procedural Interface

cloudstorage_dropbox_do_listchanges($res, $folderresource);

Remarks

This method lists changes to resources within the specified FolderResource.

FolderResource must be a folder path, an Id-based relative folder path, a folder resource Id, or empty string (the root folder). The IncludeDeleted, IncludeMounted, MaxResults, and RecurseSubfolders configuration settings may be used to further control the scope of the results.

Note that the values of FolderResource and the aforementioned configuration settings are all ignored if either ChangeMarker or NextChangeMarker is populated (the markers encode the values used originally).

Starting from a Baseline State

For most use-cases, it is necessary to obtain a baseline state first in order to have a context onto which later changes can be applied.

To obtain a baseline state, ensure that both ChangeMarker and NextChangeMarker are empty, and then call ListChanges. Then follow the process described in the "General Usage" section (below) until ChangeMarker is empty, keeping in mind that the results being returned are not necessarily* changes, but rather the current state of resources within the scope determined by FolderResource, IncludeDeleted, IncludeMounted, and RecurseSubfolders.

*If any resources in the aforementioned scope are changed before all result pages of the baseline have been returned, Dropbox may append those change items to the end of the baseline's results. Refer to the "Usage Considerations" section (below) for more information.

Starting from the Latest State

For use-cases that don't require a baseline state (e.g., perhaps an application just displays a "ticker" with change information), call GetCurrentChangeMarker. This will populate NextChangeMarker immediately.

General Usage

When this method is called, it will use the change marker stored in either ChangeMarker or NextChangeMarker (only one can be populated at a time) to request the next page of changes. This method causes the ResourceList event to fire once for each change, and will also populate the Resources properties.

If there are still more changes available to list when this method returns, the ChangeMarker property will be populated. Continue to call this method until ChangeMarker is empty to accumulate all pages of results in the Resources properties. (Once there aren't any more changes available to list, the NextChangeMarker property will be populated instead.) Alternatively, the AccumulatePages configuration setting can be disabled to clear the Resources properties every time a page of results is returned.

When NextChangeMarker is populated, it is always populated with a value that (at the time of population) points to the most current state. (Since "the most current state" implies that there are no further changes to list, calling ListChanges immediately after NextChangeMarker is populated will not return any further changes.)

Example of Getting a Baseline and then Listing Changes // Get the baseline state first. Dropbox dropbox = new Dropbox(); dropbox.ListChanges(""); do { // Continue to call ListChanges() until ChangeMarker is the empty string (indicating there // are no more changes to list). dropbox.ListChanges(""); } while (dropbox.ChangeMarker.Length > 0); for (int i = 0; i < dropbox.Resources.Count; i++) { // Apply the baseline state. } // Now NextChangeMarker will be populated. If we were to call ListChanges() again right now, // nothing would be listed and NextChangeMarker would still be populated. // Wait at least 2 minutes for changes to occur. Assume something changes while we wait. dropbox.WaitForChanges(120); // (Note that this is a blocking call.) dropbox.ListChanges(""); do { dropbox.ListChanges(""); } while (dropbox.ChangeMarker.Length > 0); for (int i = 0; i < dropbox.Resources.Count; i++) { // Apply the changes. }

Usage Considerations

When working with Dropbox changes, keep in mind that it is possible for a resource, uniquely identified by its Id, to appear more than once in a change set. (This can happen if changes are being listed, and then a change occurs before all result pages in the change set are returned; Dropbox will then typically append the new change to the end of the current change set.) Since a Dropbox change always reflects the latest state of a resource, just use the latest one.

ListResources Method (CloudStorage_Dropbox Class)

Lists resources.

Object Oriented Interface

public function doListResources($folderresource);

Procedural Interface

cloudstorage_dropbox_do_listresources($res, $folderresource);

Remarks

This method lists resources within the specified FolderResource.

FolderResource must be a folder path, an Id-based relative folder path, a folder resource Id, or empty string (the root folder). The IncludeDeleted, IncludeMounted, MaxResults, and RecurseSubfolders configuration settings may be used to further control the scope of the results.

Note that the values of FolderResource and the aforementioned configuration settings are all ignored if ResourceMarker is populated (the marker encodes the values used originally).

Calling this method will fire the ResourceList event once for each resource, and will also populate the Resources properties.

If there are still more resources available to list when this method returns, the ResourceMarker property will be populated. Continue to call this method until ResourceMarker is empty to accumulate all pages of results in the Resources properties. Alternatively, the AccumulatePages configuration setting can be disabled to clear the Resources properties every time a page of results is returned. // ResourceList event handler. dropbox.OnResourceList += (s, e) => { Console.WriteLine(e.Name); }; do { dropbox.ListResources("/work_files/serious_business/cats"); for (int i = 0; i < dropbox.Resources.Count; i++) { // Process resources here. } } while (!string.IsNullOrEmpty(dropbox.ResourceMarker));

ListRevisions Method (CloudStorage_Dropbox Class)

Lists revisions for a file path or file resource Id.

Object Oriented Interface

public function doListRevisions($fileresource);

Procedural Interface

cloudstorage_dropbox_do_listrevisions($res, $fileresource);

Remarks

This method lists revisions for a specific file path or for a specific file resource Id. This method is not supported for folder resources.

FileResource must be a file path, an Id-based relative file path, or a file resource Id.

Calling this method will fire the ResourceList event once for each resource, and will also populate the Resources properties.

The MaxRevisionResults configuration setting controls the maximum number of results returned. (Note that unlike the class's other listing methods, the results returned by this method are never paged; MaxRevisionResults specifies the overall limit rather than the page size limit.)

Path-based vs. Id-based Revision Histories

When listing revisions, the server can return the revision history either by path or by Id. A path's revision history will include revisions for any and all files that have been located there; while an Id's revision history will only return revisions for the associated file resource (regardless of where it's been located over time).

By default, the class chooses which mode the server should use automatically each time ListRevisions is called based on the kind of resource identifier passed for the FileResource parameter. If a path (or an Id-based relative path) is provided, it chooses the path-based mode; and if a file resource Id is provided, it chooses the Id-based mode.

The ListRevisionsMode configuration setting can be used to explicitly control which revision listing mode the server should use. // ResourceList event handler. dropbox.OnResourceList += (s, e) => { Console.WriteLine(e.Name + ", Revision: " + e.Revision); }; dropbox.ListRevisions("/work_stuff/serious_business/best_cat_pictures.zip"); for (int i = 0; i < dropbox.Resources.Count; i++) { // Process resource revisions here. }

ListSharedLinks Method (CloudStorage_Dropbox Class)

Lists shared links created by the current user.

Object Oriented Interface

public function doListSharedLinks($resource);

Procedural Interface

cloudstorage_dropbox_do_listsharedlinks($res, $resource);

Remarks

This method lists shared links created by the current user. If Resource is empty string, all of the user's shared links will be returned. If Resource is non-empty, the results will be limited to just shared links that provide access to the resource in question (direct links and links to any parent folders).

Resource must be a path, an Id-based relative path, a resource Id, or empty string.

Calling this method will fire the SharedLinkList event once for each shared link, and will also populate the SharedLinks properties.

If there are still more shared links available to list when this method returns, the SharedLinkMarker property will be populated. Continue to call this method until SharedLinkMarker is empty to accumulate all pages of results in the SharedLinks properties. // SharedLinkList event handler. dropbox.OnSharedLinkList += (s, e) => { Console.WriteLine(e.Name + ", URL: " + e.URL); }; // List all of the shared links created by the current user. do { dropbox.ListSharedLinks(""); for (int i = 0; i < dropbox.SharedLinks.Count; i++) { // Process shared links here. } } while (!string.IsNullOrEmpty(dropbox.SharedLinkMarker));

MoveResource Method (CloudStorage_Dropbox Class)

Moves a resource.

Object Oriented Interface

public function doMoveResource($fromresource, $toresourcepath);

Procedural Interface

cloudstorage_dropbox_do_moveresource($res, $fromresource, $toresourcepath);

Remarks

This method moves the resource FromResource to a new path ToResourcePath.

FromResource must be a path, an Id-based relative path, or a resource Id. ToResourcePath must be a path or an Id-based relative path (it must always end with the name of the file/folder resource being moved).

The AllowOwnershipTransfers configuration setting must be enabled before calling this method if a move operation would result in the current user transferring their ownership to another user (or to a team).

The RenameIfExists configuration setting may be enabled before calling this method to have the server automatically resolve naming conflicts.

Reset Method (CloudStorage_Dropbox Class)

Resets the class to its initial state.

Object Oriented Interface

public function doReset();

Procedural Interface

cloudstorage_dropbox_do_reset($res);

Remarks

This method resets the class to its initial state.

RestoreResource Method (CloudStorage_Dropbox Class)

Restores a given file resource revision.

Object Oriented Interface

public function doRestoreResource($revision, $toresourcepath);

Procedural Interface

cloudstorage_dropbox_do_restoreresource($res, $revision, $toresourcepath);

Remarks

This method restores a the specified Revision of a file resource, saving it to the given path ToResourcePath. Restoring a deleted file resource can also be done using this method as long as the revision Id is known (there's no way to obtain revision Ids for file resources which have already been deleted; this is a limitation of the Dropbox API).

Revision must be a revision Id. ToResourcePath must be a file path (and it must end with the desired name of the file resource being restored).

RevokeLink Method (CloudStorage_Dropbox Class)

Revokes a shared link.

Object Oriented Interface

public function doRevokeLink($sharedlink);

Procedural Interface

cloudstorage_dropbox_do_revokelink($res, $sharedlink);

Remarks

This method revokes an existing shared link; SharedLink must be a shared link URL.

Keep in mind that a resource may still be accessible after revoking its shared link if shared links still exist for any of its parent folders. The ListSharedLinks method can be used to get a list of all existing links that provide access to any given resource.

Search Method (CloudStorage_Dropbox Class)

Searches for resources.

Object Oriented Interface

public function doSearch($folderresource, $query);

Procedural Interface

cloudstorage_dropbox_do_search($res, $folderresource, $query);

Remarks

This method searches for resources matching Query within the specified FolderResource.

FolderResource must be a folder path, an Id-based, relative folder path, a folder resource Id, or empty string (in which case the current user's entire Dropbox is searched). The SearchCategories, SearchFileExtensions, SearchKind, and SearchNamesOnly properties may be used to further control the search options the server uses.

Calling this method will fire the ResourceList event once for each search result, and will also populate the Resources properties.

If there are still more search results available to list when this method returns, the SearchMarker property will be populated. Continue to call this method until SearchMarker is empty to accumulate all pages of results in the Resources properties.

The MaxSearchResults configuration setting can be used to control how many results are returned each time this method is called.

SendCustomRequest Method (CloudStorage_Dropbox Class)

Sends a custom request to the Dropbox API.

Object Oriented Interface

public function doSendCustomRequest($httpmethod, $requestpath, $requestbody);

Procedural Interface

cloudstorage_dropbox_do_sendcustomrequest($res, $httpmethod, $requestpath, $requestbody);

Remarks

This method can be used to send arbitrary requests to the Dropbox API.

Valid values for HttpMethod are:

  • GET
  • POST (default if empty)

The value passed for RequestPath must already be URL-encoded in a manner acceptable to the Dropbox API. The RequestBody parameter may be empty if not needed.

Usage

When this method is called, the class does the following:

  1. Builds a request URL, including query parameters, as follows:
    • The specified RequestPath is appended to the Dropbox API endpoint, https://api.dropboxapi.com/2.
    • All query parameters in the QueryParams properties are added to the request URL.
  2. Sends the request using the specified HttpMethod, the request URL build in step 1, the header information held by Authorization and OtherHeaders, and the given RequestBody (if non-empty).
  3. Stores the response headers in the ParsedHeaders properties, and the response body in the specified LocalFile, or ResourceData (using the same logic as DownloadFile).

If the response body is JSON data, the XPath, XText, and other X* configuration settings can then be used to navigate and extract information from it.

UploadFile Method (CloudStorage_Dropbox Class)

Uploads a file resource.

Object Oriented Interface

public function doUploadFile($newfileresource);

Procedural Interface

cloudstorage_dropbox_do_uploadfile($res, $newfileresource);

Remarks

This method uploads a new file resource (or potentially updates or overwrites an existing one). The Id of the newly-created (or updated) file resource is returned.

NewFileResource must be a file path, an Id-based relative file path, or (only when updating/overwriting) a file resource Id.

Name Conflict Resolution

The class automatically chooses how the server should resolve name conflicts (which occur if the specified NewFileResource already exists) based on the current values of the IfRevision and RenameIfExists configuration settings and the Overwrite property. The following steps describe how the choice is made:

  1. If the uploaded file data is identical to the contents of the existing file resource, the server will always ignore the upload attempt and return a successful response, regardless of what IfRevision, RenameIfExists, and Overwrite are currently set to. (This is a Dropbox server-side behavior that cannot be changed.)
  2. Otherwise, if IfRevision is populated, then the existing file resource will have its contents updated as long as its latest revision Id matches the one held by IfRevision. If the revision Ids don't match, then RenameIfExists decides the outcome:
    • If RenameIfExists is true, then a new file resource is created with a unique name that contains "conflicted copy".
    • If RenameIfExists is false, then the upload fails.
  3. Otherwise, if RenameIfExists is true, then a new file resource is created with a unique name.
  4. Otherwise, if Overwrite is true, then the existing file resource is overwritten with a new one.
  5. Otherwise, the upload fails.

If LocalFile is set the file will be uploaded from the specified path. If LocalFile is not set the data in ResourceData will be used.

To encrypt the file before uploading it, set EncryptionAlgorithm and EncryptionPassword.

Upload Notes

Dropbox offers two ways to upload a file. For smaller files a simple upload option is provided to upload data in one request. This is the default option. For larger files, uploads can be fragmented into multiple pieces, allowing resuming of uploads that may be interrupted.

Simple

By default the class uses the simple upload mechanism. dropbox.LocalFile = "../MyFile.zip"; dropbox.UploadFile("/MyFile.zip");

Resumable

To enable resumable uploads set UseResumableUpload to true. This is recommended for large files. The class will automatically fragment the specified file into smaller pieces and upload each individually. FragmentSize may be set to specify the size of the fragment if desired. The default fragment size is 10 MB.

When UseResumableUpload is set to true and UploadFile is called, a resumable upload session is started by the class. UploadSessionId is populated with a resumable upload session Id identifying the session (this value may be needed for additional operations if the upload does not complete normally).

During a resumable upload, the FragmentComplete event fires after each fragment is uploaded to indicate overall progress. The class also updates StartByte as necessary to indicate the current offset in the file.

If the upload is interrupted for any reason, resuming it is easy. First, verify that UploadSessionId and StartByte are populated (if the same instance of the class is used, they should already be populated, and no special action should be needed). Then call UploadFile again to resume the upload at the specified StartByte offset.

Note that if the upload is not resumed after some time the upload session will expire. dropbox.LocalFile = "../MyFile.zip"; dropbox.UploadFile("MyFile.zip"); //The transfer is interrupted and UploadFile() above fails. Later, resume the download. //Using the same instance StartByte and ResumeURL are already populated from the previous //upload attempt. dropbox.UploadFile("MyFile.zip");

WaitForChanges Method (CloudStorage_Dropbox Class)

Waits a certain amount of time for changes to occur.

Object Oriented Interface

public function doWaitForChanges($timeout);

Procedural Interface

cloudstorage_dropbox_do_waitforchanges($res, $timeout);

Remarks

This method blocks for Timeout seconds, waiting for changes to occur within the scope represented by the current NextChangeMarker (which must already be populated). If any changes occur, returns true; otherwise returns false.

Timeout must be a value between 30 and 480 seconds (inclusive). Note that Dropbox also adds 90 seconds of random jitter to this value. This method may return early if changes occur before the total timeout expires.

If this method returns true, use ListChanges to retrieve the changes.

Note that this method will automatically change the value of Timeout property as necessary when called; and will restore the original value before returning. // Get the baseline state first. Dropbox dropbox = new Dropbox(); dropbox.ListChanges(""); do { // Continue to call ListChanges() until ChangeMarker is the empty string (indicating there // are no more changes to list). dropbox.ListChanges(""); } while (dropbox.ChangeMarker.Length > 0); for (int i = 0; i < dropbox.Resources.Count; i++) { // Apply the baseline state. } // Now NextChangeMarker will be populated. If we were to call ListChanges() again right now, // nothing would be listed and NextChangeMarker would still be populated. // Wait at least 2 minutes for changes to occur. Assume something changes while we wait. dropbox.WaitForChanges(120); // (Note that this is a blocking call.) dropbox.ListChanges(""); do { dropbox.ListChanges(""); } while (dropbox.ChangeMarker.Length > 0); for (int i = 0; i < dropbox.Resources.Count; i++) { // Apply the changes. }

EndTransfer Event (CloudStorage_Dropbox Class)

This event fires when a document finishes transferring.

Object Oriented Interface

public function fireEndTransfer($param);

Procedural Interface

cloudstorage_dropbox_register_callback($res, 1, array($this, 'fireEndTransfer'));

Parameter List

 'direction'

Remarks

The EndTransfer event is fired when the document text finishes transferring from the server to the local host.

The Direction parameter shows whether the client (0) or the server (1) is sending the data.

Error Event (CloudStorage_Dropbox Class)

Fired when information is available about errors during data delivery.

Object Oriented Interface

public function fireError($param);

Procedural Interface

cloudstorage_dropbox_register_callback($res, 2, array($this, 'fireError'));

Parameter List

 'errorcode'
'description'

Remarks

The Error event is fired in case of exceptional conditions during message processing. Normally the class fails with an error.

The ErrorCode parameter contains an error code, and the Description parameter contains a textual description of the error. For a list of valid error codes and their descriptions, please refer to the Error Codes section.

FragmentComplete Event (CloudStorage_Dropbox Class)

Fires after each fragment of a resumable upload is completed.

Object Oriented Interface

public function fireFragmentComplete($param);

Procedural Interface

cloudstorage_dropbox_register_callback($res, 3, array($this, 'fireFragmentComplete'));

Parameter List

 'fragmentnumber'
'fragmentcount'
'interrupt'

Remarks

When UseResumableUpload is true and UploadFile is called, this event will fire after each fragment is uploaded, providing an indication of overall upload progress.

FragmentNumber is the number of the current fragment that has completed. This value starts at 1.

FragmentCount is the total number of fragments that will be uploaded.

Interrupt can be set to true to interrupt the upload. The upload may be resumed later.

Header Event (CloudStorage_Dropbox Class)

Fired every time a header line comes in.

Object Oriented Interface

public function fireHeader($param);

Procedural Interface

cloudstorage_dropbox_register_callback($res, 4, array($this, 'fireHeader'));

Parameter List

 'field'
'value'

Remarks

The Field parameter contains the name of the HTTP header (which is the same as it is delivered). The Value parameter contains the header contents.

If the header line being retrieved is a continuation header line, then the Field parameter contains "" (empty string).

Log Event (CloudStorage_Dropbox Class)

Fired once for each log message.

Object Oriented Interface

public function fireLog($param);

Procedural Interface

cloudstorage_dropbox_register_callback($res, 5, array($this, 'fireLog'));

Parameter List

 'loglevel'
'message'
'logtype'

Remarks

This event is fired once for each log message generated by the class. The verbosity is controlled by the LogLevel setting.

LogLevel indicates the level of message. Possible values are as follows:

0 (None) No events are logged.
1 (Info - default) Informational events are logged.
2 (Verbose) Detailed data are logged.
3 (Debug) Debug data are logged.

The value 1 (Info) logs basic information, including the URL, HTTP version, and status details.

The value 2 (Verbose) logs additional information about the request and response.

The value 3 (Debug) logs the headers and body for both the request and response, as well as additional debug information (if any).

Message is the log entry.

LogType identifies the type of log entry. Possible values are as follows:

  • "Info"
  • "RequestHeaders"
  • "ResponseHeaders"
  • "RequestBody"
  • "ResponseBody"
  • "ProxyRequest"
  • "ProxyResponse"
  • "FirewallRequest"
  • "FirewallResponse"

Progress Event (CloudStorage_Dropbox Class)

Fires during an upload or download to indicate transfer progress.

Object Oriented Interface

public function fireProgress($param);

Procedural Interface

cloudstorage_dropbox_register_callback($res, 6, array($this, 'fireProgress'));

Parameter List

 'direction'
'bytestransferred'
'totalbytes'
'percentdone'

Remarks

This event fires during an upload or download to indicate the progress of the transfer of the entire request. By default, this event will fire each time PercentDone increases by one percent; the ProgressStep configuration setting can be used to alter this behavior.

Direction indicates whether the transfer is an upload (0) or a download (1).

BytesTransferred reflects the number of bytes that have been transferred so far, or 0 if the transfer is starting (however, see note below).

TotalBytes reflects the total number of bytes that are to be transferred, or -1 if the total is unknown. This amount includes the size of everything in the request like HTTP headers.

PercentDone reflects the overall progress of the transfer, or -1 if the progress cannot be calculated.

Note: By default, the class tracks transfer progress absolutely. If a transfer is interrupted and later resumed, the values reported by this event upon and after resumption will account for the data that was transferred before the interruption.

For example, if 10MB of data was successfully transferred before the interruption, then this event will fire with a BytesTransferred value of 10485760 (10MB) when the transfer is first resumed, and then continue to fire with successively greater values as usual.

This behavior can be changed by disabling the ProgressAbsolute configuration setting, in which case the class will treat resumed transfers as "new" transfers. In this case, the BytesTransferred parameter will always be 0 the first time this event fires, regardless of whether the transfer is new or being resumed.

ResourceList Event (CloudStorage_Dropbox Class)

Fires once for each resource returned when listing resources, changes, or revisions.

Object Oriented Interface

public function fireResourceList($param);

Procedural Interface

cloudstorage_dropbox_register_callback($res, 7, array($this, 'fireResourceList'));

Parameter List

 'id'
'name'
'path'
'resourcetype'
'modifiedtime'
'size'
'accesstype'
'revision'
'hash'
'deleted'

Remarks

This event fires once for each resource returned when ListResources, GetResourceInfo, Search, ListChanges, or ListRevisions is called.

Id is the Id of the resource.

Name is the name of the resource.

Path is the path of the resource.

ResourceType reflects the resource's type. Possible values are:

0 (drtFile) A file.
1 (drtFolder) A folder.

ModifiedTime reflects the last modified time of the file resource, as reported by the server. Not applicable for folder resources. Timestamps are formatted according to ISO 8601 and are always in UTC time.

Size is the size of the file resource, in bytes. Not applicable for folder resources.

AccessType reflects the type of access the current user has to the resource. Possible values are:

0 (atUnrestricted) The user's access to the resource is not restricted.
1 (atReadOnly) The user has read-only access to the resource. This indicates that the resource is, or is located within, a read-only shared folder.
2 (atLimited) The user has limited access to the immediate contents of the folder resource (by virtue of having access to one or more other resources located somewhere within the folder). See further notes below. Only applicable to folders.
3 (atNoAccess) The user is allowed to see that the folder resource exists, but may not access its contents. Only applicable to folders.

An access type of 2 (atLimited) still allows the user to call ListResources for a folder, but the results will be limited to the subset of resources within that folder that the user can actually access (including any further limited-access subfolders).

Revision is the revision Id of the file resource. Note applicable for folder resources.

Hash holds a hash of the file resource's content. Not applicable for folder resources.

Deleted indicates whether the resource has been deleted.

SharedLinkList Event (CloudStorage_Dropbox Class)

Fires once for each shared link returned when listing shared links.

Object Oriented Interface

public function fireSharedLinkList($param);

Procedural Interface

cloudstorage_dropbox_register_callback($res, 8, array($this, 'fireSharedLinkList'));

Parameter List

 'url'
'name'
'id'
'path'
'resourcetype'
'visibility'
'expires'

Remarks

This event fires once for each shared link returned when ListSharedLinks is called.

URL is the URL of the shared link.

Name is the name of the linked resource.

Id is Id of the linked resource.

Path is the path of the linked resource.

ResourceType reflects the linked resource's type. Possible values are:

0 (lrtFile) A file.
1 (lrtFolder) A folder.

Visibility reflects the visibility of the link. Possible values are:

0 (lvPublic) Anyone with the link can access the linked resource.
1 (lvTeamOnly) Only members of the same team with the link can access the linked resource. (Only applicable to Dropbox Business.)
2 (lvPassword) Anyone with the link and the link's password can access the linked resource.
3 (lvTeamAndPassword) Only members of the same team with the link and the link's password can access the linked resource. (Only applicable to Dropbox Business.)
4 (lvSharedFolderOnly) Only members (with the link) of the shared folder containing the linked resource can access it.

Expires is the expiration timestamp of the link (or empty string, if the link doesn't expire). Timestamps are formatted according to ISO 8601 and are always in UTC time.

SSLServerAuthentication Event (CloudStorage_Dropbox Class)

Fired after the server presents its certificate to the client.

Object Oriented Interface

public function fireSSLServerAuthentication($param);

Procedural Interface

cloudstorage_dropbox_register_callback($res, 9, array($this, 'fireSSLServerAuthentication'));

Parameter List

 'certencoded'
'certsubject'
'certissuer'
'status'
'accept'

Remarks

During this event, the client can decide whether or not to continue with the connection process. The Accept parameter is a recommendation on whether to continue or close the connection. This is just a suggestion: application software must use its own logic to determine whether or not to continue.

When Accept is False, Status shows why the verification failed (otherwise, Status contains the string OK). If it is decided to continue, you can override and accept the certificate by setting the Accept parameter to True.

SSLStatus Event (CloudStorage_Dropbox Class)

Fired when secure connection progress messages are available.

Object Oriented Interface

public function fireSSLStatus($param);

Procedural Interface

cloudstorage_dropbox_register_callback($res, 10, array($this, 'fireSSLStatus'));

Parameter List

 'message'

Remarks

The event is fired for informational and logging purposes only. This event tracks the progress of the connection.

StartTransfer Event (CloudStorage_Dropbox Class)

This event fires when a document starts transferring (after the headers).

Object Oriented Interface

public function fireStartTransfer($param);

Procedural Interface

cloudstorage_dropbox_register_callback($res, 11, array($this, 'fireStartTransfer'));

Parameter List

 'direction'

Remarks

The StartTransfer event is fired when the document text starts transferring from the server to the local host.

The Direction parameter shows whether the client (0) or the server (1) is sending the data.

Transfer Event (CloudStorage_Dropbox Class)

Fired while a document transfers (delivers document).

Object Oriented Interface

public function fireTransfer($param);

Procedural Interface

cloudstorage_dropbox_register_callback($res, 12, array($this, 'fireTransfer'));

Parameter List

 'direction'
'bytestransferred'
'percentdone'
'text'

Remarks

The Text parameter contains the portion of the document text being received. It is empty if data are being posted to the server.

The BytesTransferred parameter contains the number of bytes transferred in this Direction since the beginning of the document text (excluding HTTP response headers).

The Direction parameter shows whether the client (0) or the server (1) is sending the data.

The PercentDone parameter shows the progress of the transfer in the corresponding direction. If PercentDone can not be calculated the value will be -1.

Note: Events are not re-entrant. Performing time-consuming operations within this event will prevent it from firing again in a timely manner and may affect overall performance.

Config Settings (Dropbox Class)

The class accepts one or more of the following configuration settings. Configuration settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the class, access to these internal properties is provided through the Config method.

Dropbox Config Settings

AccountHomeNamespace:   The current user's home namespace Id.

After a successful call to GetAccountInfo this setting will be populated with the current user's home namespace Id.

AccountHomePath:   The path for the current user's home directory, if their account is part of a team.

After a successful call to GetAccountInfo, this setting will be populated with the path for the current user's home directory under their team's shared root. If the current user's account is not a member of a team, this setting will be empty.

AccountRootNamespace:   The current user's root namespace Id.

After a successful call to GetAccountInfo, this setting will be populated with the current user's root namespace Id. If the current user's account is a member of a team, this will be the Id of the team's namespace root. Otherwise, it will be the same as the AccountHomeNamespace.

AccumulatePages:   Whether the class should accumulate subsequent pages of results when listing them.

This setting controls how the class behaves when listing multiple pages of results. If this setting is enabled, each successive page of results will be appended to the appropriate collection properties until the last page of results has been listed (at which point the next list call will cause said collection to be cleared first). If this setting is disabled, the collection will be cleared every time a page of results is returned.

By default, this setting is enabled, allowing all pages of results to be accumulated in the appropriate collection properties.

AllowCopySharedFolders:   Whether to allow the copying of shared folders or their contents.

This setting must be enabled before attempting to copy shared folders (or any of their contents) using CopyResource.

This setting is disabled by default.

AllowFolderDownloads:   Whether to allow folder downloading.

This setting controls whether the DownloadFile method can be used to download folder resources. Calling DownloadFile for a folder resource with this setting enabled will cause the class to download it as a ZIP file.

This setting is disabled by default.

AllowOwnershipTransfers:   Whether to allow move operations that would result in ownership transfers.

This setting must be enabled before attempting to use MoveResource to move a resource to a location that would result in the current user losing ownership of it.

This setting is disabled by default.

ClientModifiedTime:   The client-side last modified time.

This setting may be set to an appropriately-formatted timestamp before calling UploadFile to set (or update) the client-side last modified time for the file resource.

Timestamps are formatted according to ISO 8601 and are always in UTC time.

CreateLinkExpiration:   The expiration date to assign to the link.

This setting may be set to an appropriately-formatted timestamp before calling CreateLink to specify an expiration time for it. If this setting is empty (default) when CreateLink is called, the link will never expire.

Timestamps are formatted according to ISO 8601 and are always in UTC time.

CreateLinkPassword:   The password to protect the link with.

When CreateLinkVisibility is set to 2, this setting must be set before calling CreateLink to specify the password to protect the link with.

CreateLinkVisibility:   The visibility to create links with.

This setting specifies the visibility that CreateLink should create links with. Possible values are:

0 (default) Public Anyone with the link can access the linked resource.
1 Team only Only members of the same team with the link can access the linked resource. (Only applicable to Dropbox Business.)
2 Password Anyone with the link and the link's password can access the linked resource.

Note that links created for team resources are subject to the team's access policies, and thus may end up with a different visibility than was requested.

DateFormat:   The format to use for date and time.

This setting specifies the date format for the date/time fields(e.g ModifiedTime). Below are the custom date and time format specifiers that can be used:

yyyyyear
MMmonth
ddday
hhhours
mmminutes
ssseconds
fffmilliseconds

These format specifiers can be written in any combination. For example: DropBox.Config("DateFormat=yyyy-MM-ddThh:mm:ss");

DropBox.Config("DateFormat=dd/MM/yyyy hh:mm:ss");

If this setting is not specified, the default date/time format will be yyyy-MM-ddTHH:mm:ssZ. This is from ISO 8601.

DownloadTempFile:   The temporary file used when downloading encrypted data.

This setting specifies the temporary file used when downloading encrypted data.

When downloading encrypted data with LocalFile set, the class will automatically create a temporary file at TempPath to hold the encrypted file contents. When the download is complete, the data is decrypted to LocalFile.

If the download is interrupted, the specified file will hold the partially downloaded encrypted file contents. Before resuming the download, this setting must be set to a valid file containing the partially encrypted file contents. See DownloadFile for details.

DropboxNamespacePath:   Specifies the namespace that is used for Dropbox API requests.

This setting is used to specify the ID of the namespace that should be used when making requests to the Dropbox API. When set, the Dropbox API will perform all actions relative to the specified namespace rather than to the root namespace. If the namespace does not exist or if the user does not have permissions for that namespace, any requests made to the API will return with a 422 HTTP error code.

See DropboxRootPath for more information about the root namespace.

DropboxRootPath:   Specifies the expected root for Dropbox API requests.

This setting is used to specify the ID of the root that is expected to be used when making requests to the Dropbox API. When set this configuration setting will add the Dropbox-API-Path-Root header with the namespace id of the root that is expected by the application. If the root ID has been changed, the server will respond with a 422 HTTP error code with a name space id for the new root. This can be used to inform the application that the relative paths might have changed for the current user.

When using the Dropbox API, calls that access content are "rooted" to a particular directory per the apps permission. This means that relative paths are evaluated to the root location and paths outside the root location are not accessible. The root namespace can change if the users joins, leaves, or changes teams.

To change the namespace that is used in requests, see DropboxNamespacePath.

EncryptionIV:   The initialization vector to be used for encryption/decryption.

When encrypting or decrypting a file, this setting may be set to specify the initialization vector. Normally the class will derive this value automatically from EncryptionPassword.

This setting accepts a hex encoded value.

EncryptionKey:   The key to use during encryption/decryption.

When encrypting or decrypting a file, this setting may be set to specify the key to use. Normally the class will derive this value automatically from EncryptionPassword.

This setting accepts a hex encoded value.

EncryptionPasswordKDF:   The KDF algorithm to use during password based encryption and decryption.

This setting specified the Key Derivation Function (KDF) used to derive a key from the specified EncryptionPassword. Possible values are:

  • 0 (default) - PBKDF1
  • 1 - PBKDF2
Note: PBKDF1 is not FIPS compliant. When operating in FIPS mode PBKDF2 should be used.

FragmentSize:   The fragment size.

This setting controls the fragment size, in bytes, to use while uploading files when UseResumableUpload is true. When UploadFile is called the file will be fragmented into pieces of this size.

The default value is 10485760 (10MB).

IfRevision:   A revision Id, used to modify certain requests.

This setting can be set to a revision Id before calling the following methods to modify their behavior:

  • DeleteResource: Prevents the deletion from occurring if the specified revision Id does not match the latest revision Id of the file resource specified by the Resource method parameter. (Not supported when deleting folder resources.)
  • UploadFile: Refer to the UploadFile method's documentation for information.
IncludeDeleted:   Whether deleted resources should be included in the results.

This setting specifies whether deleted resources should be included in the results when calling GetResourceInfo, ListResources, ListChanges, or GetCurrentChangeMarker.

Note that Dropbox only returns a very limited subset of metadata for deleted resources; this is a limitation of the Dropbox API that cannot be changed. Specifically, the following properties are returned:

This setting is disabled by default.

IncludeMounted:   Whether to include resources in mounted folders in the results.

This setting specifies whether resources in mounted folders (that is, app folders, shared folders, and team folders) should be included in the results when calling ListResources, ListChanges, or GetCurrentChangeMarker.

This setting is enabled by default.

ListRevisionsMode:   Controls the revision listing mode that the server should use.

When listing revisions, the server can return the revision history either by path or by Id. A path's revision history will include revisions for any and all files that have been located there; while an Id's revision history will only return revisions for the associated file resource (regardless of where it's been located over time).

By default, the class chooses which mode the server should use automatically each time ListRevisions is called based on the kind of resource identifier passed for the FileResource parameter. If a path (or an Id-based relative path) is provided, it chooses the path-based mode; and if a file resource Id is provided, it chooses the Id-based mode.

This setting can be used to explicitly control which revision listing mode the server should use. Possible values are:

0 (default) Auto The class will automatically choose which mode the server uses based on the kind of resource identifier passed to ListRevisions.
1 Path The server will always list revisions by path. If a file resource Id is passed to ListRevisions, the server will use the path of the file associated with that Id.
2 Id The server will always list revisions by file resource Id. If a path (or an Id-based relative path) is provided, the server will use the Id of the file at that path.

MaxResults:   Limits the number of resource and change results.

This setting specifies the maximum number of results that should be returned each time ListResources or ListChanges is called (it also affects the NextChangeMarker value returned by GetCurrentChangeMarker). If there are more items than can be returned, the results will be paged and the appropriate "Marker" property populated.

Acceptable values are from 1 to 2000 inclusive. The default is -1, which causes the server's default to be used.

MaxRevisionResults:   Limits the number of revision results.

This setting specifies the maximum number of results that should be returned when ListRevisions is called. (Note that unlike other listing operations, the results returned by ListRevisions cannot be paged through; this setting simply specifies a limit. This is a limitation of the Dropbox API.)

Acceptable values are from 1 to 100 inclusive. The default is -1, which causes the server's default (10) to be used.

MaxSearchResults:   Limits the number of search results.

This setting specifies the maximum number of search results that should be returned each time Search is called. If there are more items than can be returned, the results will be truncated and the SearchMarker property populated.

Acceptable values are from 1 to 1000 inclusive. The default is -1, which causes the server's default (100) to be used.

MuteFileUploads:   Whether the server should suppress file change notifications.

This setting controls whether the server should suppress the notifications that it typically sends to applicable users' Dropbox desktop clients when files are uploaded or updated.

This setting is disabled by default; UploadFile will cause the server to send file upload/update notifications.

PermanentlyDelete:   Whether resources should be permanently deleted (Dropbox Business only).

This setting controls whether resources should be deleted permanently when DeleteResource is called.

This setting is disabled by default. Permanent deletion is only supported for Dropbox Business.

ProgressAbsolute:   Whether the class should track transfer progress absolutely.

This setting controls whether the class tracks upload and download progress absolutely or relatively, with regards to the values reported via the Progress event when an interrupted transfer is resumed.

If this setting is enabled (default), then when a transfer is interrupted and later resumed, the values reported by the Progress event will account for the data that was successfully transferred before the interruption.

If this setting is disabled, then the class will treat resumed transfers as "new" transfers, and the values reported by the Progress event will start at 0 rather than from the number of bytes already transferred.

Refer to the Progress event for more information.

ProgressStep:   How often the progress event should be fired, in terms of percentage.

This setting controls how often the class will fire the Progress event during an upload or download, in terms of percentage. Valid values are 0 to 99, inclusive.

The default value, 1, will cause the Progress event to fire each time the event's PercentDone parameter value increases by one percent. Setting this setting to 0 will cause the Progress event to fire every time data is transferred.

Note that the Progress event will always fire once at the beginning and end of a transfer, regardless of this setting's value. Also, if PercentDone cannot be calculated for a particular transfer (e.g., for downloads that use chunked transfer encoding), then the class will behave as if this setting were 0 for the duration of the transfer.

RawRequest:   Returns the data that was sent to the server.

This setting may be queried after calling any method that sends data to the server to obtain the request data that was transmitted. Such data may be useful for troubleshooting purposes.

RawResponse:   Returns the data that was received from the server.

This setting may be queried after calling any method that sends data to the server to obtain the response data that was received. Such data may be useful for troubleshooting purposes.

RecurseSubfolders:   Whether to recursively list all resources within the specified folder.

This setting specifies whether calling ListResources will cause all resources within the specified folder to be listed (including those in all subfolders, recursively). This setting also affects ListChanges and GetCurrentChangeMarker.

This setting is disabled by default.

RenameIfExists:   Whether to rename newly-created resources in the event of a name conflict.

This setting specifies whether the server should rename files uploaded with UploadFile and folders created with CreateFolder if the desired name is already in use.

The name the server choses will be always unique; it will append a number to the end of the original name (for files, before the extension). That number will be incremented until a unique name is found.

This setting is disabled by default. Note that, when calling UploadFile, this setting takes precedence over the Overwrite property if both are enabled.

TempPath:   The path to the directory where temporary files are created.

This setting specifies the path where temporary files are created when downloading encrypted files. If not specified, the system's temporary directory is used. Refer to DownloadTempFile and DownloadFile for more information.

ThumbnailFormat:   The image format thumbnails should be downloaded in.

When DownloadType is set to 1 (ddtFileThumbnail), this setting specifies the image format that file thumbnails will be downloaded in when DownloadFile is called. Possible values are:

0 (default) JPEG
1 PNG
ThumbnailMode:   The mode the server should use to create thumbnails.

When DownloadType is set to 1 (ddtFileThumbnail), this setting specifies the mode the server should use to create thumbnails when DownloadFile is called. Possible values are:

0 (default) Strict Scale down the image to fit within the given ThumbnailSize.
1 Best fit Scale down the image to fit within the given ThumbnailSize or its transpose.
2 Best fit one Scale down the image to completely cover the given ThumbnailSize or its transpose.
ThumbnailSize:   The thumbnail output size.

When DownloadType is set to 1 (ddtFileThumbnail), this setting specifies the thumbnail output size the server should use. Possible values are:

0 32x32 px
1 (default) 64x64 px
2 128x128 px
3 256x256 px
4 480x320 px
5 640x480 px
6 960x640 px
7 1024x768 px
8 2048x1536 px
Note that the actual output size of each thumbnail may vary based the currently selected ThumbnailMode option.
XChildCount:   The number of child elements of the current element.

This configuration settings specifies the number of child attributes of the current element. The XChild configuration settings will be indexed from 0 to (XChildCount - 1).

The current element is specified through the XPath configuration setting. This configuration setting is read-only.

XChildName[i]:   The name of the child element.

This configuration setting provides the name of the i-th child element of the current element.

The current element is specified through the XPath configuration setting. This configuration setting is read-only.

XChildXText[i]:   The inner text of the child element.

This configuration setting provides the inner text of the i-th child element of the current element.

The current element is specified through the XPath configuration setting. This configuration setting is read-only.

XElement:   The name of the current element.

This configuration setting provides the name of the current element.

The current element is specified through the XPath configuration setting. This configuration setting is read-only.

XParent:   The parent of the current element.

This configuration setting provides the parent of the current element.

The current element is specified through the XPath configuration setting. This configuration setting is read-only.

XPath:   Provides a way to point to a specific element in the returned XML or JSON response.

The XPath setting allows you to point to specific elements in the XML or JSON response.

When XPath is set to a valid path, XElement points to the name of the element, with XText, XParent, XSubTree, XChildCount, XChildName[i], and XChildXText[i] providing other properties of the element.

XPath syntax is available for both XML and JSON documents. An XPath is a series of one or more element accessors separated by the / character, for example, /A/B/C/D. An XPath can be absolute (i.e., it starts with /), or it can be relative to the current XPath location.

The following are possible values for an element accessor, which operates relative to the current location specified by the XPath accessors, which proceed it in the overall XPath string:

Accessor Description
name The first element with a particular name. Can be *.
[i] The i-th element.
name[i] The i-th element with a particular name.
[last()] The last element.
[last()-i] The element i before the last element.
name[@attrname="attrvalue"]The first element with a particular name that contains the specified attribute-value pair.

Supports single and double quotes. (XML Only)

. The current element.
.. The parent element.
Note: XPath indices are 1-based.

For example, assume the following XML and JSON responses.

XML:

<firstlevel>
  <one>value</one>
  <two>
    <item>first</item>
    <item>second</item>
  </two>
  <three>value three</three>
</firstlevel>

JSON:

{
  "firstlevel": {
    "one": "value",
    "two": ["first", "second"],
    "three": "value three"
  }
}

The following are examples of valid XPaths for these responses:

DescriptionXML XPath JSON XPath
Document root / /json
Specific element /firstlevel/one /json/firstlevel/one
i-th child /firstlevel/two/item[2]/json/firstlevel/two/[2]

This list is not exhaustive, but it provides a general idea of the possibilities.

XSubTree:   A snapshot of the current element in the document.

This configuration setting provides the entirety of the current element (including its subelements).

The current element is specified through the XPath configuration setting. This configuration setting is read-only.

XText:   The text of the current element.

This configuration setting provides the inner text of the current element.

The current element is specified in the XPath configuration setting. This configuration setting is read-only.

OAuth Config Settings

OAuthAccessTokenExpiration:   The lifetime of the access token.

This setting holds the lifetime of the access token in seconds. For instance the value 3600 indicates that the token will expire in one hour from the time it was generated.

OAuthAuthorizationTokenType:   The type of access token returned.

The applicable values include the following:

Bearer (default)When the access token returned by the server is a Bearer type, the authorization string returned by Authorize will be in the format "Bearer access_token". This can be supplied as the value of the HTTP Authorization header.
OAuthAutomaticRefresh:   Whether or not to refresh an expired access token automatically.

When this setting is set to true and the Authorization property is not set, the class will automatically get a new access token if it has the necessary properties to do so without user interaction.

For example, when using the Authorization Code grant type, the OAuthRefreshToken property should be set to a valid refresh token. When using the Client Credential grant type however, the class does not need any additional properties set as it can already get a new access token without user interaction.

OAuthBrowserResponseTimeout:   Specifies the amount of time to wait for a response from the browser.

This setting specifies the amount of time (in seconds) the class will wait for a response from the browser when requesting user authentication. The default value is 0, meaning that the class will wait indefinitely.

OAuthIncludeEmptyRedirectURI:   Whether an empty redirect_uri parameter is included in requests.

This setting specifies whether redirect_uri is included in the request made by Authorize if it is empty.

If set to true (default) the redirect_uri will be sent in all cases. If set to false the redirect_uri will only be sent if it has a value.

OAuthJWTPayload:   The payload of the JWT access token if present.

This configuration setting provides the payload section of a JWT access token if the access token is a JWT and the class is able to parse out the payload section. This setting only applies to access tokens that are returned from a service provider after successfully authorizing and authenticating with the service.

To parse the payload for specific claims, see OAuthJWTXPath.

OAuthJWTXChildCount:   The number of child elements of the current element.

The number of child attributes of the current element. The OAuthJWTXChildCount configuration settings will be indexed from 0 to (OAuthJWTXChildCount - 1).

The current element is specified in the OAuthJWTXPath configuration setting. This configuration setting is read-only.

OauthJWTXChildName[i]:   The name of the child element.

Provides the name of the i'th child element of the current element.

The current element is specified in the OAuthJWTXPath configuration setting. This configuration setting is read-only.

OAuthJWTXChildXText[i]:   The inner text of the child element.

Provides the inner text of the i'th child element of the current element.

The current element is specified in the OAuthJWTXPath configuration setting. This configuration setting is read-only.

OAuthJWTXElement:   The name of the current element.

Provides the name of the current element.

The current element is specified in the OAuthJWTXPath configuration setting. This configuration setting is read-only.

OauthJWTXParent:   The parent of the current element.

Provides the parent of the current element.

The current element is specified in the OAuthJWTXPath configuration setting. This configuration setting is read-only.

OAuthJWTXPath:   Provides a way to point to a specific element in the returned payload of a JWT based access token.

The OAuthJWTXPath setting allows you to point to specific claims within the payload of a JWT based access token.

XPath syntax is available for the payload of JWT based access tokens if available. An XPath is a series of one or more element accessors separated by the / character, for example: /A/B/C/D.

The following are possible values for an element accessor, which operates relative to the current location specified by the XPath accessors which proceed it in the overall XPath string:

Accessor Description
name The first element with a particular name. Can be *.
[i] The i-th element.
name[i] The i-th element with a particular name.
[last()] The last element.
[last()-i] The element i before the last element.
Here are some examples of valid XPaths and some common claims:
DescriptionJSON XPath
Document root /json
Specific element /json/element_one
Username Claim (Microsoft Specific) /json/preferred_username
Registered Application Name Claim (Microsoft Specific) /json/app_displayname

This is not an exhaustive list by any means, but should provide a general idea of the possibilities. To get the text of the specified element, see OAuthJWTXText.

OAuthJWTXSubTree:   A snapshot of the current element in the document.

Provides the entirety of the current element (including its sub-elements).

The current element is specified in the OAuthJWTXPath configuration setting. This configuration setting is read-only.

OAuthJWTXText:   The text of the current element.

Provides the inner text of the current element.

The current element is specified in the OAuthJWTXPath configuration setting. This configuration setting is read-only.

OAuthParamCount:   Specifies the number of additional parameters variables to include in the request.

This setting can be used to add query string parameters to the outgoing request. One common use for this method would be to add the "state" parameter to the request, which can be used when the OAuthClientProfile is cocpWeb to add user defined data. The authorization server will include the "state" parameter in the response and will be available in the post back to your server which will allow you to maintain state in your application. This is used in conjunction with OAuthParamName[i] and OAuthParamValue[i]. For instance:

component.Config("OAuthParamCount=2"); component.Config("OAuthParamName[0]=myvar"); component.Config("OAuthParamValue[0]=myvalue"); component.Config("OAuthParamName[1]=testname"); component.Config("OAuthParamValue[1]=testvalue");

Additionally, this will also be updated to hold the parameters returned in the response.

for (int i = 0; i < int.Parse(component.Config("OAuthParamCount")); i++) { string name = component.Config("OAuthParamName[" + i + "]"); string value = component.Config("OAuthParamValue[" + i + "]"); }

OAuthParamName[i]:   Specifies the parameter name at the specified index.

This setting can be used to retrieve or specify the parameter variable name at the index specified. See OAuthParamCount for details.

OAuthParamValue[i]:   Specifies the parameter value at the specified index.

This setting can be used to retrieve or specify the parameter variable value at the index specified. See OAuthParamCount for details.

OAuthPasswordGrantUsername:   Used in the Resource Owner Password grant type.

Used to set the username property when the OAuthGrantType is set to the password grant type and Authorize is called.

OAuthPKCEChallengeEncoding:   The PKCE code challenge method to use.

This setting controls the PKCE code challenge method used when OAuthUsePKCE is set to true. Possible values are:

  • 1 (Plain)
  • 2 (S256/SHA256 - default)
OAuthPKCEVerifier:   The PKCE verifier used to generate the challenge.

This configuration setting when queried provides the PKCE verifier that is used to generate the PKCE challenge for the Authorize method and the OAuthWebAuthURL field when OAuthUsePKCE is set to true. When using the cocpWeb OAuthClientProfile, the configuration setting can be set instead to allow the authorization request to be made from a different instance than the authentication (token) request.

OAuthResetData:   Determines if the Reset method applies to the OAuth settings.

If set to true (default), the Reset method will reset the OAuth settings including any authorization fields like OAuthAccessToken and OAuthRefreshToken. This means the Authorize method must be called again to get new authorization information. When set to false, the Reset method will not reset the OAuth property and the OAuth* configuration settings. This allows for the class to be reset without having to get authorization again.

OAuthReUseWebServer:   Determines if the same server instance is used between requests.

If set to true (default), the same embedded web server instance will be used for multiple requests. If set to false the embedded web server will be created and destroyed on each call to Authorize

OAuthTransferredRequest:   The full OAuth request last sent by the client.

This configuration setting returns the full OAuth request last sent by the client. For performance reasons, the request is not normally saved. Set this configuration setting to ON before making a request to enable it. Following are examples of this request:

.NET Gmail gmail = new Gmail(); gmail.Config("OAuthTransferredRequest=on"); gmail.Authorize(); Console.WriteLine(gmail.Config("OAuthTransferredRequest")); C++ Gmail gmail; gmail.Config("OAuthTransferredRequest=on"); gmail.Authorize(); printf("%s\r\n", gmail.Config("OAuthTransferredRequest"));

OAuthUsePKCE:   Specifies if PKCE should be used.

If set to true (default), Proof Key for Code Exchange (PKCE) defined by RFC 7636 will be used when performing authorization. This setting applies when using the Authorization Code OAuthGrantType. The OAuthPKCEChallengeEncoding configuration setting can be used to control the code challenge method that will be used.

OAuthWebServerActive:   Specifies and controls whether the embedded web server is active.

The setting when queried will return the current state of the web server. If the webserver is active, it will return "true" and if it is inactive it will return "false".

This setting can also be set to activate or deactivate the web server. Under normal circumstances, this would not be required as the class will automatically start and stop the web server when Authorize is called. In certain cases, it is required to start the webserver before calling Authorize. For example, if the OAuthReturnURL needs to be set to a relay server, then you will need to start the web server manually. Another example would be when the OAuthReUseWebServer is set to true, the server will not be automatically stopped, and this configuration setting must be set to "false" to stop the embedded web server.

OAuthWebServerCertStore:   The certificate with private key to use when SSL is enabled.

The name of the certificate store used for the embedded web server's SSL.

The OAuthWebServerCertStoreType property specifies the type of the certificate store specified by OAuthWebServerCertStore. If the store is password protected, specify the password in OAuthWebServerCertStorePassword.

OAuthWebServerCertStore is used in conjunction with the OAuthWebServerCertSubject property in order to specify the certificate to be used during SSL.

Designations of certificate stores are platform dependent.

The following designations are the most common User and Machine certificate stores in Windows:

MYA certificate store holding personal certificates with their associated private keys.
CACertifying authority certificates.
ROOTRoot certificates.

When the certificate store type is cstPFXFile, this property must be set to the name of the file. When the type is cstPFXBlob, the property must be set to the binary contents of a PFX file (i.e., PKCS#12 certificate store).

Note: This is required when OAuthWebServerSSLEnabled is set to true.

OAuthWebServerCertStorePassword:   The certificate with private key to use when SSL is enabled.

If the certificate store is of a type that requires a password, this property is used to specify that password in order to open the certificate store.

Note: This is only applicable when OAuthWebServerSSLEnabled is set to true.

OAuthWebServerCertStoreType:   The certificate with private key to use when SSL is enabled.

This specifies the type of certificate store. Possible values are:

0 User - This is the default for Windows. This specifies that the certificate store is a certificate store owned by the current user. Note: This store type is not available in Java.
1 Machine - For Windows, this specifies that the certificate store is a machine store. Note: This store type is not available in Java.
2 PFXFile - The certificate store is the name of a PFX (PKCS12) file containing certificates.
3 PFXBlob - The certificate store is a string (binary or Base64-encoded) representing a certificate store in PFX (PKCS12) format.
4 JKSFile - The certificate store is the name of a Java Key Store (JKS) file containing certificates. Note: This store type is available only in Java.
5 JKSBlob - The certificate store is a string (binary or Base64-encoded) representing a certificate store in Java Key Store (JKS) format. Note: This store type is available only in Java.
6 PEMKeyFile - The certificate store is the name of a PEM-encoded file that contains a private key and an optional certificate.
7 PEMKeyBlob - The certificate store is a string (binary or Base64-encoded) that contains a private key and an optional certificate.
14 PPKFile - The certificate store is the name of a file that contains a PPK (PuTTY Private Key).
15 PPKBlob - The certificate store is a string (binary) that contains a PPK (PuTTY Private Key).
16 XMLFile - The certificate store is the name of a file that contains a certificate in XML format.
17 XMLBlob - The certificate store is a string that contains a certificate in XML format.
Note: This is required when OAuthWebServerSSLEnabled is set to true.
OAuthWebServerCertSubject:   The certificate with private key to use when SSL is enabled.

The subject of the SSL certificate.

The special value "*" picks a random certificate in the certificate store.

The certificate subject is a comma-separated list of distinguished name fields and values. For instance, "CN=www.server.com, OU=test, C=US, E=support@nsoftware.com". Common fields and their meanings are as follows:

FieldMeaning
CNCommon Name. This is commonly a hostname like www.server.com.
OOrganization
OUOrganizational Unit
LLocality
SState
CCountry
EEmail Address

If a field value contains a comma, it must be quoted.

Note: This is required when OAuthWebServerSSLEnabled is set to true.

OAuthWebServerFailedResponse:   The custom response that will be displayed to the user if authentication failed.

When Authorize is called the user will be redirected to the embedded web server upon completing authentication with the authorization server. If authentication failed, the HTML specified here will be sent to the user's browser.

OAuthWebServerHost:   The hostname used by the embedded web server displayed in the ReturnURL.

This setting specifies the hostname used by the embedded web server when OAuthClientProfile is set to cocpApplication. This specifies the interface on which the embedded web server listens, and also the value displayed in the OAuthReturnURL. This should be set to the hostname only, not the full URL.

The default value is localhost.

OAuthWebServerPort:   The local port on which the embedded web server listens.

This property specifies the port on which the embedded web server listens. Setting this to 0 (default) enables the system to choose a port at random. The chosen port will be returned when this setting is queried after the server has started listening.This is only applicable when using the embedded web server.

OAuthWebServerResponse:   The custom response that will be displayed to the user.

When Authorize is called the user will be redirected to the embedded web server upon completing authentication with the authorization server. This setting allows you to specify the HTML that will be sent to the user's browser.

OAuthWebServerSSLEnabled:   Whether the web server requires SSL connections.

This setting specifies whether the embedded web server will use SSL. If set to True OAuthWebServerCert* configs are required and the server will only accept SSL connections. If set to False only plaintext connects are supported.

HTTP Config Settings

AcceptEncoding:   Used to tell the server which types of content encodings the client supports.

When AllowHTTPCompression is True, the class adds an Accept-Encoding header to the request being sent to the server. By default, this header's value is "gzip, deflate". This configuration setting allows you to change the value of the Accept-Encoding header. Note: The class only supports gzip and deflate decompression algorithms.

AllowHTTPCompression:   This property enables HTTP compression for receiving data.

This configuration setting enables HTTP compression for receiving data. When set to True (default), the class will accept compressed data. It then will uncompress the data it has received. The class will handle data compressed by both gzip and deflate compression algorithms.

When True, the class adds an Accept-Encoding header to the outgoing request. The value for this header can be controlled by the AcceptEncoding configuration setting. The default value for this header is "gzip, deflate".

The default value is True.

AllowHTTPFallback:   Whether HTTP/2 connections are permitted to fallback to HTTP/1.1.

This configuration setting controls whether HTTP/2 connections are permitted to fall back to HTTP/1.1 when the server does not support HTTP/2. This setting is applicable only when HTTPVersion is set to "2.0".

If set to True (default), the class will automatically use HTTP/1.1 if the server does not support HTTP/2. If set to False, the class fails with an error if the server does not support HTTP/2.

The default value is True.

Append:   Whether to append data to LocalFile.

This configuration setting determines whether data will be appended when writing to LocalFile. When set to True, downloaded data will be appended to LocalFile. This may be used in conjunction with Range to resume a failed download. This is applicable only when LocalFile is set. The default value is False.

Authorization:   The Authorization string to be sent to the server.

If the Authorization property contains a nonempty string, an Authorization HTTP request header is added to the request. This header conveys Authorization information to the server.

This property is provided so that the HTTP class can be extended with other security schemes in addition to the authorization schemes already implemented by the class.

The AuthScheme property defines the authentication scheme used. In the case of HTTP Basic Authentication (default), every time User and Password are set, they are Base64 encoded, and the result is put in the Authorization property in the form "Basic [encoded-user-password]".

BytesTransferred:   Contains the number of bytes transferred in the response data.

This configuration setting returns the raw number of bytes from the HTTP response data, before the component processes the data, whether it is chunked or compressed. This returns the same value as the Transfer event, by BytesTransferred.

ChunkSize:   Specifies the chunk size in bytes when using chunked encoding.

This is applicable only when UseChunkedEncoding is True. This setting specifies the chunk size in bytes to be used when posting data. The default value is 16384.

CompressHTTPRequest:   Set to true to compress the body of a PUT or POST request.

If set to True, the body of a PUT or POST request will be compressed into gzip format before sending the request. The "Content-Encoding" header is also added to the outgoing request.

The default value is False.

EncodeURL:   If set to True the URL will be encoded by the class.

If set to True, the URL passed to the class will be URL encoded. The default value is False.

FollowRedirects:   Determines what happens when the server issues a redirect.

This option determines what happens when the server issues a redirect. Normally, the class returns an error if the server responds with an "Object Moved" message. If this property is set to 1 (always), the new URL for the object is retrieved automatically every time.

If this property is set to 2 (Same Scheme), the new URL is retrieved automatically only if the URL Scheme is the same; otherwise, the class fails with an error.

Note: Following the HTTP specification, unless this option is set to 1 (Always), automatic redirects will be performed only for GET or HEAD requests. Other methods potentially could change the conditions of the initial request and create security vulnerabilities.

Furthermore, if either the new URL server or port are different from the existing one, User and Password are also reset to empty, unless this property is set to 1 (Always), in which case the same credentials are used to connect to the new server.

A Redirect event is fired for every URL the product is redirected to. In the case of automatic redirections, the Redirect event is a good place to set properties related to the new connection (e.g., new authentication parameters).

The default value is 0 (Never). In this case, redirects are never followed, and the class fails with an error instead.

Following are the valid options:

  • 0 - Never
  • 1 - Always
  • 2 - Same Scheme

GetOn302Redirect:   If set to True the class will perform a GET on the new location.

The default value is False. If set to True, the class will perform a GET on the new location. Otherwise, it will use the same HTTP method again.

HTTP2HeadersWithoutIndexing:   HTTP2 headers that should not update the dynamic header table with incremental indexing.

HTTP/2 servers maintain a dynamic table of headers and values seen over the course of a connection. Typically, these headers are inserted into the table through incremental indexing (also known as HPACK, defined in RFC 7541). To tell the component not to use incremental indexing for certain headers, and thus not update the dynamic table, set this configuration option to a comma-delimited list of the header names.

HTTPVersion:   The version of HTTP used by the class.

This property specifies the HTTP version used by the class. Possible values are as follows:

  • "1.0"
  • "1.1" (default)
  • "2.0"
  • "3.0"

When using HTTP/2 ("2.0"), additional restrictions apply. Please see the following notes for details.

HTTP/2 Notes

When using HTTP/2, a secure Secure Sockets Layer/Transport Layer Security (TLS/SSL) connection is required. Attempting to use a plaintext URL with HTTP/2 will result in an error.

If the server does not support HTTP/2, the class will automatically use HTTP/1.1 instead. This is done to provide compatibility without the need for any additional settings. To see which version was used, check NegotiatedHTTPVersion after calling a method. The AllowHTTPFallback setting controls whether this behavior is allowed (default) or disallowed.

HTTP/3 Notes

HTTP/3 is supported only in .NET and Java.

When using HTTP/3, a secure (TLS/SSL) connection is required. Attempting to use a plaintext URL with HTTP/3 will result in an error.

IfModifiedSince:   A date determining the maximum age of the desired document.

If this setting contains a nonempty string, an If-Modified-Since HTTP header is added to the request. The value of this header is used to make the HTTP request conditional: if the requested documented has not been modified since the time specified in the field, a copy of the document will not be returned from the server; instead, a 304 (not modified) response will be returned by the server and the component throws an exception

The format of the date value for IfModifiedSince is detailed in the HTTP specs. For example: Sat, 29 Oct 2017 19:43:31 GMT.

KeepAlive:   Determines whether the HTTP connection is closed after completion of the request.

If true, the component will not send the Connection: Close header. The absence of the Connection header indicates to the server that HTTP persistent connections should be used if supported. Note: Not all servers support persistent connections. If false, the connection will be closed immediately after the server response is received.

The default value for KeepAlive is false.

KerberosSPN:   The Service Principal Name for the Kerberos Domain Controller.

If the Service Principal Name on the Kerberos Domain Controller is not the same as the URL that you are authenticating to, the Service Principal Name should be set here.

LogLevel:   The level of detail that is logged.

This configuration setting controls the level of detail that is logged through the Log event. Possible values are as follows:

0 (None) No events are logged.
1 (Info - default) Informational events are logged.
2 (Verbose) Detailed data are logged.
3 (Debug) Debug data are logged.

The value 1 (Info) logs basic information, including the URL, HTTP version, and status details.

The value 2 (Verbose) logs additional information about the request and response.

The value 3 (Debug) logs the headers and body for both the request and response, as well as additional debug information (if any).

MaxRedirectAttempts:   Limits the number of redirects that are followed in a request.

When FollowRedirects is set to any value other than frNever, the class will follow redirects until this maximum number of redirect attempts are made. The default value is 20.

NegotiatedHTTPVersion:   The negotiated HTTP version.

This configuration setting may be queried after the request is complete to indicate the HTTP version used. When HTTPVersion is set to "2.0" (if the server does not support "2.0"), then the class will fall back to using "1.1" automatically. This setting will indicate which version was used.

OtherHeaders:   Other headers as determined by the user (optional).

This configuration setting can be set to a string of headers to be appended to the HTTP request headers.

The headers must follow the format "header: value" as described in the HTTP specifications. Header lines should be separated by CRLF ("\r\n") .

Use this configuration setting with caution. If this configuration setting contains invalid headers, HTTP requests may fail.

This configuration setting is useful for extending the functionality of the class beyond what is provided.

ProxyAuthorization:   The authorization string to be sent to the proxy server.

This is similar to the Authorization configuration setting, but is used for proxy authorization. If this configuration setting contains a nonempty string, a Proxy-Authorization HTTP request header is added to the request. This header conveys proxy Authorization information to the server. If ProxyUser and ProxyPassword are specified, this value is calculated using the algorithm specified by ProxyAuthScheme.

ProxyAuthScheme:   The authorization scheme to be used for the proxy.

This configuration setting is provided for use by classs that do not directly expose Proxy properties.

ProxyPassword:   A password if authentication is to be used for the proxy.

This configuration setting is provided for use by classs that do not directly expose Proxy properties.

ProxyPort:   Port for the proxy server (default 80).

This configuration setting is provided for use by classs that do not directly expose Proxy properties.

ProxyServer:   Name or IP address of a proxy server (optional).

This configuration setting is provided for use by classs that do not directly expose Proxy properties.

ProxyUser:   A user name if authentication is to be used for the proxy.

This configuration setting is provided for use by classs that do not directly expose Proxy properties.

SentHeaders:   The full set of headers as sent by the client.

This configuration setting returns the complete set of raw headers as sent by the client.

StatusCode:   The status code of the last response from the server.

This configuration setting contains the result code of the last response from the server.

StatusLine:   The first line of the last response from the server.

This setting contains the first line of the last response from the server. The format of the line will be [HTTP version] [Result Code] [Description].

TransferredData:   The contents of the last response from the server.

This configuration setting contains the contents of the last response from the server.

TransferredDataLimit:   The maximum number of incoming bytes to be stored by the class.

If TransferredDataLimit is set to 0 (default), no limits are imposed. Otherwise, this reflects the maximum number of incoming bytes that can be stored by the class.

TransferredHeaders:   The full set of headers as received from the server.

This configuration setting returns the complete set of raw headers as received from the server.

TransferredRequest:   The full request as sent by the client.

This configuration setting returns the full request as sent by the client. For performance reasons, the request is not normally saved. Set this configuration setting to ON before making a request to enable it. Following are examples of this request:

.NET Http http = new Http(); http.Config("TransferredRequest=on"); http.PostData = "body"; http.Post("http://someserver.com"); Console.WriteLine(http.Config("TransferredRequest")); C++ HTTP http; http.Config("TransferredRequest=on"); http.SetPostData("body", 5); http.Post("http://someserver.com"); printf("%s\r\n", http.Config("TransferredRequest"));

UseChunkedEncoding:   Enables or Disables HTTP chunked encoding for transfers.

If UseChunkedEncoding is set to True, the class will use HTTP-chunked encoding when posting, if possible. HTTP-chunked encoding allows large files to be sent in chunks instead of all at once. If set to False, the class will not use HTTP-chunked encoding. The default value is False.

Note: Some servers (such as the ASP.NET Development Server) may not support chunked encoding.

UseIDNs:   Whether to encode hostnames to internationalized domain names.

This configuration setting specifies whether hostnames containing non-ASCII characters are encoded to internationalized domain names. When set to True, if a hostname contains non-ASCII characters, it is encoded using Punycode to an IDN (internationalized domain name).

The default value is False and the hostname will always be used exactly as specified. Note: The CodePage setting must be set to a value capable of interpreting the specified host name. For instance, to specify UTF-8, set CodePage to 65001. In the C++ Edition for Windows, the *W version of the class must be used. For instance, DNSW or HTTPW.

UsePlatformHTTPClient:   Whether or not to use the platform HTTP client.

When using this configuration setting, if True, the component will use the default HTTP client for the platform (URLConnection in Java, WebRequest in .NET, or CFHTTPMessage in Mac/iOS) instead of the internal HTTP implementation. This is important for environments in which direct access to sockets is limited or not allowed (e.g., in the Google AppEngine).

Note: This setting is applicable only to Mac/iOS editions.

UseProxyAutoConfigURL:   Whether to use a Proxy auto-config file when attempting a connection.

This configuration specifies whether the class will attempt to use the Proxy auto-config URL when establishing a connection and ProxyAutoDetect is set to True.

When True (default), the class will check for the existence of a Proxy auto-config URL, and if found, will determine the appropriate proxy to use.

UserAgent:   Information about the user agent (browser).

This is the value supplied in the HTTP User-Agent header. The default setting is "IPWorks HTTP Component - www.nsoftware.com".

Override the default with the name and version of your software.

TCPClient Config Settings

ConnectionTimeout:   Sets a separate timeout value for establishing a connection.

When set, this configuration setting allows you to specify a different timeout value for establishing a connection. Otherwise, the class will use Timeout for establishing a connection and transmitting/receiving data.

FirewallAutoDetect:   Tells the class whether or not to automatically detect and use firewall system settings, if available.

This configuration setting is provided for use by classs that do not directly expose Firewall properties.

FirewallHost:   Name or IP address of firewall (optional).

If a FirewallHost is given, requested connections will be authenticated through the specified firewall when connecting.

If the FirewallHost setting is set to a Domain Name, a DNS request is initiated. Upon successful termination of the request, the FirewallHost setting is set to the corresponding address. If the search is not successful, an error is returned.

Note: This setting is provided for use by classs that do not directly expose Firewall properties.

FirewallPassword:   Password to be used if authentication is to be used when connecting through the firewall.

If FirewallHost is specified, the FirewallUser and FirewallPassword settings are used to connect and authenticate to the given firewall. If the authentication fails, the class fails with an error.

Note: This setting is provided for use by classs that do not directly expose Firewall properties.

FirewallPort:   The TCP port for the FirewallHost;.

The FirewallPort is set automatically when FirewallType is set to a valid value.

Note: This configuration setting is provided for use by classs that do not directly expose Firewall properties.

FirewallType:   Determines the type of firewall to connect through.

Possible values are as follows:

0No firewall (default setting).
1Connect through a tunneling proxy. FirewallPort is set to 80.
2Connect through a SOCKS4 Proxy. FirewallPort is set to 1080.
3Connect through a SOCKS5 Proxy. FirewallPort is set to 1080.
10Connect through a SOCKS4A Proxy. FirewallPort is set to 1080.

Note: This setting is provided for use by classs that do not directly expose Firewall properties.

FirewallUser:   A user name if authentication is to be used connecting through a firewall.

If the FirewallHost is specified, the FirewallUser and FirewallPassword settings are used to connect and authenticate to the Firewall. If the authentication fails, the class fails with an error.

Note: This setting is provided for use by classs that do not directly expose Firewall properties.

KeepAliveInterval:   The retry interval, in milliseconds, to be used when a TCP keep-alive packet is sent and no response is received.

When set, TCPKeepAlive will automatically be set to True. A TCP keep-alive packet will be sent after a period of inactivity as defined by KeepAliveTime. If no acknowledgment is received from the remote host, the keep-alive packet will be sent again. This configuration setting specifies the interval at which the successive keep-alive packets are sent in milliseconds. This system default if this value is not specified here is 1 second.

Note: This value is not applicable in macOS.

KeepAliveTime:   The inactivity time in milliseconds before a TCP keep-alive packet is sent.

When set, TCPKeepAlive will automatically be set to True. By default, the operating system will determine the time a connection is idle before a Transmission Control Protocol (TCP) keep-alive packet is sent. This system default if this value is not specified here is 2 hours. In many cases, a shorter interval is more useful. Set this value to the desired interval in milliseconds.

Linger:   When set to True, connections are terminated gracefully.

This property controls how a connection is closed. The default is True.

In the case that Linger is True (default), two scenarios determine how long the connection will linger. In the first, if LingerTime is 0 (default), the system will attempt to send pending data for a connection until the default IP timeout expires.

In the second scenario, if LingerTime is a positive value, the system will attempt to send pending data until the specified LingerTime is reached. If this attempt fails, then the system will reset the connection.

The default behavior (which is also the default mode for stream sockets) might result in a long delay in closing the connection. Although the class returns control immediately, the system could hold system resources until all pending data are sent (even after your application closes).

Setting this property to False forces an immediate disconnection. If you know that the other side has received all the data you sent (e.g., by a client acknowledgment), setting this property to False might be the appropriate course of action.

LingerTime:   Time in seconds to have the connection linger.

LingerTime is the time, in seconds, the socket connection will linger. This value is 0 by default, which means it will use the default IP timeout.

LocalHost:   The name of the local host through which connections are initiated or accepted.

The LocalHost setting contains the name of the local host as obtained by the gethostname() system call, or if the user has assigned an IP address, the value of that address.

In multihomed hosts (machines with more than one IP interface), setting LocalHost to the value of an interface will make the class initiate connections (or accept in the case of server classs) only through that interface.

If the class is connected, the LocalHost setting shows the IP address of the interface through which the connection is made in internet dotted format (aaa.bbb.ccc.ddd). In most cases, this is the address of the local host, except for multihomed hosts (machines with more than one IP interface).

LocalPort:   The port in the local host where the class binds.

This configuration setting must be set before a connection is attempted. It instructs the class to bind to a specific port (or communication endpoint) in the local machine.

Setting this to 0 (default) enables the system to choose a port at random. The chosen port will be shown by LocalPort after the connection is established.

LocalPort cannot be changed once a connection is made. Any attempt to set this when a connection is active will generate an error.

This configuration setting is useful when trying to connect to services that require a trusted port on the client side. An example is the remote shell (rsh) service in UNIX systems.

MaxLineLength:   The maximum amount of data to accumulate when no EOL is found.

MaxLineLength is the size of an internal buffer, which holds received data while waiting for an EOL string.

If an EOL string is found in the input stream before MaxLineLength bytes are received, the DataIn event is fired with the EOL parameter set to True, and the buffer is reset.

If no EOL is found, and MaxLineLength bytes are accumulated in the buffer, the DataIn event is fired with the EOL parameter set to False, and the buffer is reset.

The minimum value for MaxLineLength is 256 bytes. The default value is 2048 bytes.

MaxTransferRate:   The transfer rate limit in bytes per second.

This configuration setting can be used to throttle outbound TCP traffic. Set this to the number of bytes to be sent per second. By default, this is not set and there is no limit.

ProxyExceptionsList:   A semicolon separated list of hosts and IPs to bypass when using a proxy.

This configuration setting optionally specifies a semicolon-separated list of hostnames or IP addresses to bypass when a proxy is in use. When requests are made to hosts specified in this property, the proxy will not be used. For instance:

www.google.com;www.nsoftware.com

TCPKeepAlive:   Determines whether or not the keep alive socket option is enabled.

If set to True, the socket's keep-alive option is enabled and keep-alive packets will be sent periodically to maintain the connection. Set KeepAliveTime and KeepAliveInterval to configure the timing of the keep-alive packets.

Note: This value is not applicable in Java.

TcpNoDelay:   Whether or not to delay when sending packets.

When set to True, the socket will send all data that are ready to send at once. When set to False, the socket will send smaller buffered packets of data at small intervals. This is known as the Nagle algorithm.

By default, this configuration setting is set to False.

UseIPv6:   Whether to use IPv6.

When set to 0 (default), the class will use IPv4 exclusively. When set to 1, the class will use IPv6 exclusively. To instruct the class to prefer IPv6 addresses, but use IPv4 if IPv6 is not supported on the system, this setting should be set to 2. The default value is 0. Possible values are as follows:

0 IPv4 only
1 IPv6 only
2 IPv6 with IPv4 fallback

SSL Config Settings

LogSSLPackets:   Controls whether SSL packets are logged when using the internal security API.

When SSLProvider is set to Internal, this configuration setting controls whether Secure Sockets Layer (SSL) packets should be logged. By default, this configuration setting is False, as it is useful only for debugging purposes.

When enabled, SSL packet logs are output using the SSLStatus event, which will fire each time an SSL packet is sent or received.

Enabling this configuration setting has no effect if SSLProvider is set to Platform.

OpenSSLCADir:   The path to a directory containing CA certificates.

This functionality is available only when the provider is OpenSSL.

The path set by this property should point to a directory containing CA certificates in PEM format. The files each contain one CA certificate. The files are looked up by the CA subject name hash value, which must hence be available. If more than one CA certificate with the same name hash value exist, the extension must be different (e.g., 9d66eef0.0, 9d66eef0.1). OpenSSL recommends the use of the c_rehash utility to create the necessary links. Please refer to the OpenSSL man page SSL_CTX_load_verify_locations(3) for details.

OpenSSLCAFile:   Name of the file containing the list of CA's trusted by your application.

This functionality is available only when the provider is OpenSSL.

The file set by this property should contain a list of CA certificates in PEM format. The file can contain several CA certificates identified by the following sequences:

-----BEGIN CERTIFICATE-----

... (CA certificate in base64 encoding) ...

-----END CERTIFICATE-----

Before, between, and after the certificate text is allowed, which can be used, for example, for descriptions of the certificates. Refer to the OpenSSL man page SSL_CTX_load_verify_locations(3) for details.

OpenSSLCipherList:   A string that controls the ciphers to be used by SSL.

This functionality is available only when the provider is OpenSSL.

The format of this string is described in the OpenSSL man page ciphers(1) section "CIPHER LIST FORMAT". Please refer to it for details. The default string "DEFAULT" is determined at compile time and is normally equivalent to "ALL:!ADH:RC4+RSA:+SSLv2:@STRENGTH".

OpenSSLPrngSeedData:   The data to seed the pseudo random number generator (PRNG).

This functionality is available only when the provider is OpenSSL.

By default, OpenSSL uses the device file "/dev/urandom" to seed the PRNG, and setting OpenSSLPrngSeedData is not required. If set, the string specified is used to seed the PRNG.

ReuseSSLSession:   Determines if the SSL session is reused.

If set to True, the class will reuse the context if and only if the following criteria are met:

  • The target host name is the same.
  • The system cache entry has not expired (default timeout is 10 hours).
  • The application process that calls the function is the same.
  • The logon session is the same.
  • The instance of the class is the same.

SSLCACertFilePaths:   The paths to CA certificate files on Unix/Linux.

This configuration setting specifies the paths on disk to CA certificate files on Unix/Linux.

The value is formatted as a list of paths separated by semicolons. The class will check for the existence of each file in the order specified. When a file is found, the CA certificates within the file will be loaded and used to determine the validity of server or client certificates.

The default value is as follows:

/etc/ssl/ca-bundle.pem;/etc/pki/tls/certs/ca-bundle.crt;/etc/ssl/certs/ca-certificates.crt;/etc/pki/tls/cacert.pem

SSLCACerts:   A newline separated list of CA certificates to be included when performing an SSL handshake.

When SSLProvider is set to Internal, this configuration setting specifies one or more CA certificates to be included with the SSLCert property. Some servers or clients require the entire chain, including CA certificates, to be presented when performing SSL authentication. The value of this configuration setting is a newline-separated (CR/LF) list of certificates. For instance:

-----BEGIN CERTIFICATE-----
MIIEKzCCAxOgAwIBAgIRANTET4LIkxdH6P+CFIiHvTowDQYJKoZIhvcNAQELBQAw
... Intermediate Cert ...
eWHV5OW1K53o/atv59sOiW5K3crjFhsBOd5Q+cJJnU+SWinPKtANXMht+EDvYY2w
F0I1XhM+pKj7FjDr+XNj
-----END CERTIFICATE-----
\r \n
-----BEGIN CERTIFICATE-----
MIIEFjCCAv6gAwIBAgIQetu1SMxpnENAnnOz1P+PtTANBgkqhkiG9w0BAQUFADBp
... Root Cert ...
d8q23djXZbVYiIfE9ebr4g3152BlVCHZ2GyPdjhIuLeH21VbT/dyEHHA
-----END CERTIFICATE-----

SSLCheckCRL:   Whether to check the Certificate Revocation List for the server certificate.

This configuration setting specifies whether the class will check the Certificate Revocation List (CRL) specified by the server certificate. If set to 1 or 2, the class will first obtain the list of CRL URLs from the server certificate's CRL distribution points extension. The class will then make HTTP requests to each CRL endpoint to check the validity of the server's certificate. If the certificate has been revoked or any other issues are found during validation the class fails with an error.

When set to 0 (default), the CRL check will not be performed by the class. When set to 1, it will attempt to perform the CRL check, but it will continue without an error if the server's certificate does not support CRL. When set to 2, it will perform the CRL check and will throw an error if CRL is not supported.

This configuration setting is supported only in the Java, C#, and C++ editions. In the C++ edition, it is supported only on Windows operating systems.

SSLCheckOCSP:   Whether to use OCSP to check the status of the server certificate.

This configuration setting specifies whether the class will use OCSP to check the validity of the server certificate. If set to 1 or 2, the class will first obtain the Online Certificate Status Protocol (OCSP) URL from the server certificate's OCSP extension. The class will then locate the issuing certificate and make an HTTP request to the OCSP endpoint to check the validity of the server's certificate. If the certificate has been revoked or any other issues are found during validation, the class fails with an error.

When set to 0 (default), the class will not perform an OCSP check. When set to 1, it will attempt to perform the OCSP check, but it will continue without an error if the server's certificate does not support OCSP. When set to 2, it will perform the OCSP check and will throw an error if OCSP is not supported.

This configuration setting is supported only in the Java, C#, and C++ editions. In the C++ edition, it is supported only on Windows operating systems.

SSLCipherStrength:   The minimum cipher strength used for bulk encryption.

This minimum cipher strength is largely dependent on the security modules installed on the system. If the cipher strength specified is not supported, an error will be returned when connections are initiated.

Note: This configuration setting contains the minimum cipher strength requested from the security library. The actual cipher strength used for the connection is shown by the SSLStatus event.

Use this configuration setting with caution. Requesting a lower cipher strength than necessary could potentially cause serious security vulnerabilities in your application.

When the provider is OpenSSL, SSLCipherStrength is currently not supported. This functionality is instead made available through the OpenSSLCipherList configuration setting.

SSLClientCACerts:   A newline separated list of CA certificates to use during SSL client certificate validation.

This configuration setting is only applicable to server components (e.g., TCPServer) see SSLServerCACerts for client components (e.g., TCPClient). This setting can be used to optionally specify one or more CA certificates to be used when verifying the client certificate that is presented by the client during the SSL handshake when SSLAuthenticateClients is enabled. When verifying the client's certificate, the certificates trusted by the system will be used as part of the verification process. If the client's CA certificates are not installed to the trusted system store, they may be specified here so they are included when performing the verification process. This configuration setting should be set only if the client's CA certificates are not already trusted on the system and cannot be installed to the trusted system store.

The value of this configuration setting is a newline-separated (CR/LF) list of certificates. For instance:

-----BEGIN CERTIFICATE-----
MIIEKzCCAxOgAwIBAgIRANTET4LIkxdH6P+CFIiHvTowDQYJKoZIhvcNAQELBQAw
... Intermediate Cert ...
eWHV5OW1K53o/atv59sOiW5K3crjFhsBOd5Q+cJJnU+SWinPKtANXMht+EDvYY2w
F0I1XhM+pKj7FjDr+XNj
-----END CERTIFICATE-----
\r \n
-----BEGIN CERTIFICATE-----
MIIEFjCCAv6gAwIBAgIQetu1SMxpnENAnnOz1P+PtTANBgkqhkiG9w0BAQUFADBp
... Root Cert ...
d8q23djXZbVYiIfE9ebr4g3152BlVCHZ2GyPdjhIuLeH21VbT/dyEHHA
-----END CERTIFICATE-----

SSLEnabledCipherSuites:   The cipher suite to be used in an SSL negotiation.

This configuration setting enables the cipher suites to be used in SSL negotiation.

By default, the enabled cipher suites will include all available ciphers ("*").

The special value "*" means that the class will pick all of the supported cipher suites. If SSLEnabledCipherSuites is set to any other value, only the specified cipher suites will be considered.

Multiple cipher suites are separated by semicolons.

Example values when SSLProvider is set to Platform include the following: obj.config("SSLEnabledCipherSuites=*"); obj.config("SSLEnabledCipherSuites=CALG_AES_256"); obj.config("SSLEnabledCipherSuites=CALG_AES_256;CALG_3DES"); Possible values when SSLProvider is set to Platform include the following:

When TLS 1.3 is negotiated (see SSLEnabledProtocols), only the following cipher suites are supported:

  • TLS_AES_256_GCM_SHA384
  • TLS_CHACHA20_POLY1305_SHA256
  • TLS_AES_128_GCM_SHA256

SSLEnabledCipherSuites is used together with SSLCipherStrength.

SSLEnabledProtocols:   Used to enable/disable the supported security protocols.

This configuration setting is used to enable or disable the supported security protocols.

Not all supported protocols are enabled by default. The default value is 4032 for client components, and 3072 for server components. To specify a combination of enabled protocol versions set this config to the binary OR of one or more of the following values:

TLS1.312288 (Hex 3000)
TLS1.23072 (Hex C00) (Default - Client and Server)
TLS1.1768 (Hex 300) (Default - Client)
TLS1 192 (Hex C0) (Default - Client)
SSL3 48 (Hex 30)
SSL2 12 (Hex 0C)

Note that only TLS 1.2 is enabled for server components that accept incoming connections. This adheres to industry standards to ensure a secure connection. Client components enable TLS 1.0, TLS 1.1, and TLS 1.2 by default and will negotiate the highest mutually supported version when connecting to a server, which should be TLS 1.2 in most cases.

SSLEnabledProtocols: Transport Layer Security (TLS) 1.3 Notes:

By default when TLS 1.3 is enabled, the class will use the internal TLS implementation when the SSLProvider is set to Automatic for all editions.

In editions that are designed to run on Windows, SSLProvider can be set to Platform to use the platform implementation instead of the internal implementation. When configured in this manner, please note that the platform provider is supported only on Windows 11/Windows Server 2022 and up. The default internal provider is available on all platforms and is not restricted to any specific OS version.

If set to 1 (Platform provider), please be aware of the following notes:

  • The platform provider is available only on Windows 11/Windows Server 2022 and up.
  • SSLEnabledCipherSuites and other similar SSL configuration settings are not supported.
  • If SSLEnabledProtocols includes both TLS 1.3 and TLS 1.2, these restrictions are still applicable even if TLS 1.2 is negotiated. Enabling TLS 1.3 with the platform provider changes the implementation used for all TLS versions.

SSLEnabledProtocols: SSL2 and SSL3 Notes:

SSL 2.0 and 3.0 are not supported by the class when the SSLProvider is set to internal. To use SSL 2.0 or SSL 3.0, the platform security API must have the protocols enabled and SSLProvider needs to be set to platform.

SSLEnableRenegotiation:   Whether the renegotiation_info SSL extension is supported.

This configuration setting specifies whether the renegotiation_info SSL extension will be used in the request when using the internal security API. This configuration setting is false by default, but it can be set to true to enable the extension.

This configuration setting is applicable only when SSLProvider is set to Internal.

SSLIncludeCertChain:   Whether the entire certificate chain is included in the SSLServerAuthentication event.

This configuration setting specifies whether the Encoded parameter of the SSLServerAuthentication event contains the full certificate chain. By default this value is False and only the leaf certificate will be present in the Encoded parameter of the SSLServerAuthentication event.

If set to True, all certificates returned by the server will be present in the Encoded parameter of the SSLServerAuthentication event. This includes the leaf certificate, any intermediate certificate, and the root certificate.

SSLKeyLogFile:   The location of a file where per-session secrets are written for debugging purposes.

This configuration setting optionally specifies the full path to a file on disk where per-session secrets are stored for debugging purposes.

When set, the class will save the session secrets in the same format as the SSLKEYLOGFILE environment variable functionality used by most major browsers and tools, such as Chrome, Firefox, and cURL. This file can then be used in tools such as Wireshark to decrypt TLS traffic for debugging purposes. When writing to this file, the class will only append, it will not overwrite previous values.

Note: This configuration setting is applicable only when SSLProvider is set to Internal.

SSLNegotiatedCipher:   Returns the negotiated cipher suite.

This configuration setting returns the cipher suite negotiated during the SSL handshake.

SSLNegotiatedVersion:   Returns the negotiated protocol version.

This configuration setting returns the protocol version negotiated during the SSL handshake.

Note: For server components (e.g., TCPServer), this is a per-connection configuration setting accessed by passing the ConnectionId. For example: server.Config("SSLNegotiatedVersion[connId]");

SSLSecurityFlags:   Flags that control certificate verification.

The following flags are defined (specified in hexadecimal notation). They can be ORed together to exclude multiple conditions:

0x00000001Ignore time validity status of certificate.
0x00000002Ignore time validity status of CTL.
0x00000004Ignore non-nested certificate times.
0x00000010Allow unknown certificate authority.
0x00000020Ignore wrong certificate usage.
0x00000100Ignore unknown certificate revocation status.

0x00004000Trust test root certificate.
0x80000000Ignore non-matching CN (certificate CN non-matching server name).

This functionality is currently not available when the provider is OpenSSL.

SSLServerCACerts:   A newline separated list of CA certificates to use during SSL server certificate validation.

This configuration setting is only used by client components (e.g., TCPClient) see SSLClientCACerts for server components (e.g., TCPServer). This configuration setting can be used to optionally specify one or more CA certificates to be used when connecting to the server and verifying the server certificate. When verifying the server's certificate, the certificates trusted by the system will be used as part of the verification process. If the server's CA certificates are not installed to the trusted system store, they may be specified here so they are included when performing the verification process. This configuration setting should be set only if the server's CA certificates are not already trusted on the system and cannot be installed to the trusted system store.

The value of this configuration setting is a newline-separated (CR/LF) list of certificates. For instance:

-----BEGIN CERTIFICATE-----
MIIEKzCCAxOgAwIBAgIRANTET4LIkxdH6P+CFIiHvTowDQYJKoZIhvcNAQELBQAw

-----END CERTIFICATE-----

TLS12SignatureAlgorithms:   Defines the allowed TLS 1.2 signature algorithms when SSLProvider is set to Internal.

This configuration setting specifies the allowed server certificate signature algorithms when SSLProvider is set to Internal and SSLEnabledProtocols is set to allow TLS 1.2.

When specified the class will verify that the server certificate signature algorithm is among the values specified in this configuration setting. If the server certificate signature algorithm is unsupported, the class fails with an error.

The format of this value is a comma-separated list of hash-signature combinations. For instance: component.SSLProvider = TCPClientSSLProviders.sslpInternal; component.Config("SSLEnabledProtocols=3072"); //TLS 1.2 component.Config("TLS12SignatureAlgorithms=sha256-rsa,sha256-dsa,sha1-rsa,sha1-dsa"); The default value for this configuration setting is sha512-ecdsa,sha512-rsa,sha512-dsa,sha384-ecdsa,sha384-rsa,sha384-dsa,sha256-ecdsa,sha256-rsa,sha256-dsa,sha224-ecdsa,sha224-rsa,sha224-dsa,sha1-ecdsa,sha1-rsa,sha1-dsa.

To not restrict the server's certificate signature algorithm, specify an empty string as the value for this configuration setting, which will cause the signature_algorithms TLS 1.2 extension to not be sent.

TLS12SupportedGroups:   The supported groups for ECC.

This configuration setting specifies a comma-separated list of named groups used in TLS 1.2 for ECC.

The default value is ecdhe_secp256r1,ecdhe_secp384r1,ecdhe_secp521r1.

When using TLS 1.2 and SSLProvider is set to Internal, the values refer to the supported groups for ECC. The following values are supported:

  • "ecdhe_secp256r1" (default)
  • "ecdhe_secp384r1" (default)
  • "ecdhe_secp521r1" (default)

TLS13KeyShareGroups:   The groups for which to pregenerate key shares.

This configuration setting specifies a comma-separated list of named groups used in TLS 1.3 for key exchange. The groups specified here will have key share data pregenerated locally before establishing a connection. This can prevent an additional roundtrip during the handshake if the group is supported by the server.

The default value is set to balance common supported groups and the computational resources required to generate key shares. As a result, only some groups are included by default in this configuration setting.

Note: All supported groups can always be used during the handshake even if not listed here, but if a group is used that is not present in this list, it will incur an additional roundtrip and time to generate the key share for that group.

In most cases, this configuration setting does not need to be modified. This should be modified only if there is a specific reason to do so.

The default value is ecdhe_x25519,ecdhe_secp256r1,ecdhe_secp384r1,ffdhe_2048,ffdhe_3072

The values are ordered from most preferred to least preferred. The following values are supported:

  • "ecdhe_x25519" (default)
  • "ecdhe_x448"
  • "ecdhe_secp256r1" (default)
  • "ecdhe_secp384r1" (default)
  • "ecdhe_secp521r1"
  • "ffdhe_2048" (default)
  • "ffdhe_3072" (default)
  • "ffdhe_4096"
  • "ffdhe_6144"
  • "ffdhe_8192"

TLS13SignatureAlgorithms:   The allowed certificate signature algorithms.

This configuration setting holds a comma-separated list of allowed signature algorithms. Possible values include the following:

  • "ed25519" (default)
  • "ed448" (default)

  • "ecdsa_secp384r1_sha384" (default)
  • "ecdsa_secp521r1_sha512" (default)
  • "rsa_pkcs1_sha256" (default)
  • "rsa_pkcs1_sha384" (default)
  • "rsa_pkcs1_sha512" (default)
  • "rsa_pss_sha256" (default)
  • "rsa_pss_sha384" (default)
  • "rsa_pss_sha512" (default)
The default value is rsa_pss_sha256,rsa_pss_sha384,rsa_pss_sha512,rsa_pkcs1_sha256,rsa_pkcs1_sha384,rsa_pkcs1_sha512,ecdsa_secp256r1_sha256,ecdsa_secp384r1_sha384,ecdsa_secp521r1_sha512,ed25519,ed448. This configuration setting is applicable only when SSLEnabledProtocols includes TLS 1.3.
TLS13SupportedGroups:   The supported groups for (EC)DHE key exchange.

This configuration setting specifies a comma-separated list of named groups used in TLS 1.3 for key exchange. This configuration setting should be modified only if there is a specific reason to do so.

The default value is ecdhe_x25519,ecdhe_x448,ecdhe_secp256r1,ecdhe_secp384r1,ecdhe_secp521r1,ffdhe_2048,ffdhe_3072,ffdhe_4096,ffdhe_6144,ffdhe_8192

The values are ordered from most preferred to least preferred. The following values are supported:

  • "ecdhe_x25519" (default)
  • "ecdhe_x448" (default)
  • "ecdhe_secp256r1" (default)
  • "ecdhe_secp384r1" (default)
  • "ecdhe_secp521r1" (default)
  • "ffdhe_2048" (default)
  • "ffdhe_3072" (default)
  • "ffdhe_4096" (default)
  • "ffdhe_6144" (default)
  • "ffdhe_8192" (default)

Socket Config Settings

AbsoluteTimeout:   Determines whether timeouts are inactivity timeouts or absolute timeouts.

If AbsoluteTimeout is set to True, any method that does not complete within Timeout seconds will be aborted. By default, AbsoluteTimeout is False, and the timeout is an inactivity timeout.

Note: This option is not valid for User Datagram Protocol (UDP) ports.

FirewallData:   Used to send extra data to the firewall.

When the firewall is a tunneling proxy, use this property to send custom (additional) headers to the firewall (e.g., headers for custom authentication schemes).

InBufferSize:   The size in bytes of the incoming queue of the socket.

This is the size of an internal queue in the Transmission Control Protocol (TCP)/IP stack. You can increase or decrease its size depending on the amount of data that you will be receiving. In some cases, increasing the value of the InBufferSize setting can provide significant improvements in performance.

Some TCP/IP implementations do not support variable buffer sizes. If that is the case, when the class is activated the InBufferSize reverts to its defined size. The same happens if you attempt to make it too large or too small.

OutBufferSize:   The size in bytes of the outgoing queue of the socket.

This is the size of an internal queue in the TCP/IP stack. You can increase or decrease its size depending on the amount of data that you will be sending. In some cases, increasing the value of the OutBufferSize setting can provide significant improvements in performance.

Some TCP/IP implementations do not support variable buffer sizes. If that is the case, when the class is activated the OutBufferSize reverts to its defined size. The same happens if you attempt to make it too large or too small.

Base Config Settings

BuildInfo:   Information about the product's build.

When queried, this setting will return a string containing information about the product's build.

LicenseInfo:   Information about the current license.

When queried, this setting will return a string containing information about the license this instance of a class is using. It will return the following information:

  • Product: The product the license is for.
  • Product Key: The key the license was generated from.
  • License Source: Where the license was found (e.g., RuntimeLicense, License File).
  • License Type: The type of license installed (e.g., Royalty Free, Single Server).
  • Last Valid Build: The last valid build number for which the license will work.
MaskSensitiveData:   Whether sensitive data is masked in log messages.

In certain circumstances it may be beneficial to mask sensitive data, like passwords, in log messages. Set this to true to mask sensitive data. The default is true.

This setting only works on these classes: AS3Receiver, AS3Sender, Atom, Client(3DS), FTP, FTPServer, IMAP, OFTPClient, SSHClient, SCP, Server(3DS), Sexec, SFTP, SFTPServer, SSHServer, TCPClient, TCPServer.

ProcessIdleEvents:   Whether the class uses its internal event loop to process events when the main thread is idle.

If set to False, the class will not fire internal idle events. Set this to False to use the class in a background thread on Mac OS. By default, this setting is True.

SelectWaitMillis:   The length of time in milliseconds the class will wait when DoEvents is called if there are no events to process.

If there are no events to process when DoEvents is called, the class will wait for the amount of time specified here before returning. The default value is 20.

UseFIPSCompliantAPI:   Tells the class whether or not to use FIPS certified APIs.

When set to true, the class will utilize the underlying operating system's certified APIs. Java editions, regardless of OS, utilize Bouncy Castle Federal Information Processing Standards (FIPS), while all other Windows editions make use of Microsoft security libraries.

FIPS mode can be enabled by setting the UseFIPSCompliantAPI configuration setting to true. This is a static setting that applies to all instances of all classes of the toolkit within the process. It is recommended to enable or disable this setting once before the component has been used to establish a connection. Enabling FIPS while an instance of the component is active and connected may result in unexpected behavior.

For more details, please see the FIPS 140-2 Compliance article.

Note: This setting is applicable only on Windows.

Note: Enabling FIPS compliance requires a special license; please contact sales@nsoftware.com for details.

UseInternalSecurityAPI:   Whether or not to use the system security libraries or an internal implementation.

When set to false, the class will use the system security libraries by default to perform cryptographic functions where applicable.

Setting this configuration setting to true tells the class to use the internal implementation instead of using the system security libraries.

On Windows, this setting is set to false by default. On Linux/macOS, this setting is set to true by default.

To use the system security libraries for Linux, OpenSSL support must be enabled. For more information on how to enable OpenSSL, please refer to the OpenSSL Notes section.
