The Dropbox module makes it easy to upload, download, and manage files and folders within Dropbox.

Syntax

CloudStorage.Dropbox

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* properties to set the appropriate fields for the chosen OAuthClientProfile and OAuthGrantType.

The class has the following defaults:

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 = OAuthClientProfiles.cocpApplication; dropbox.OAuth.GrantType = OAuthGrantTypes.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

External OAuth Support

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).

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 Resource* 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 Resource* properties. // 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 . 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 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

The Dropbox class offers advanced functionality beyond simple uploads and downloads. For instance:

• Encrypt and decrypt files using the EncryptionAlgorithm and EncryptionPassword properties.
• Basic file and folder manipulation and organization using methods such as CopyResource, CreateFolder, DeleteResource, and MoveResource.
• Support for resource sharing using CreateLink, ListSharedLinks, and RevokeLink.
• Change tracking with ListChanges and WaitForChanges.
• Advanced resource listing using the Search method.
• Retrieval of account and space usage details using GetAccountInfo.
• File revision handling with ListRevisions and RestoreResource.
• And more!

LocalHost Property (Dropbox Module)

The name of the local host or user-assigned IP interface through which connections are initiated or accepted.

Syntax

• Swift
• Objective-C

public var localHost: String {
  get {...}
  set {...}
}

@property (nonatomic,readwrite,assign,getter=localHost,setter=setLocalHost:) NSString* localHost;

- (NSString*)localHost;
- (void)setLocalHost :(NSString*)newLocalHost;

Default Value

""

Remarks

The LocalHost property 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 multi-homed 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 property 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 multi-homed hosts (machines with more than one IP interface).

NOTE: LocalHost is not persistent. You must always set it in code, and never in the property window.

- (int)timeout;
- (void)setTimeout :(int)newTimeout;

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 .

Please note that by default, all timeouts are inactivity timeouts, i.e. 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.

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

Config Method (Dropbox Module)

Sets or retrieves a configuration setting.

Syntax

• Swift
• Objective-C

public func config(configurationString: String) throws -> String

- (NSString*)config:(NSString*)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 (Dropbox Module)

Copies a resource.

Syntax

• Swift
• Objective-C

public func copyResource(fromResource: String, toResourcePath: String) throws -> String

- (NSString*)copyResource:(NSString*)fromResource :(NSString*)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 (Dropbox Module)

Creates a new folder resource.

Syntax

• Swift
• Objective-C

public func createFolder(newFolderPath: String) throws -> String

- (NSString*)createFolder:(NSString*)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 (Dropbox Module)

Creates a shared link for a resource.

Syntax

• Swift
• Objective-C

public func createLink(resource: String) throws -> String

- (NSString*)createLink:(NSString*)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 (Dropbox Module)

Deletes a resource.

Syntax

• Swift
• Objective-C

public func deleteResource(resource: String) throws -> Void

- (void)deleteResource:(NSString*)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 (Dropbox Module)

Downloads a file resource.

Syntax

• Swift
• Objective-C

public func downloadFile(resource: String) throws -> Void

- (void)downloadFile:(NSString*)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 ResourcesExportExtension 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);

Syntax

• Swift
• Objective-C

public func listChanges(folderResource: String) throws -> Void

- (void)listChanges:(NSString*)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 Resource* 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 Resource* properties. (Once there aren't any more changes available to list, the NextChangeMarker property will be populated instead.)

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

ListResources Method (Dropbox Module)

Lists resources.

Syntax

• Swift
• Objective-C

public func listResources(folderResource: String) throws -> Void

- (void)listResources:(NSString*)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 Resource* 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 Resource* properties. // 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 (Dropbox Module)

Lists revisions for a file path or file resource Id.

Syntax

• Swift
• Objective-C

public func listRevisions(fileResource: String) throws -> Void

- (void)listRevisions:(NSString*)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 Resource* 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 (Dropbox Module)

Lists shared links created by the current user.

Syntax

• Swift
• Objective-C

public func listSharedLinks(resource: String) throws -> Void

- (void)listSharedLinks:(NSString*)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 SharedLink* 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 SharedLink* 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 (Dropbox Module)

Moves a resource.

Syntax

• Swift
• Objective-C

public func moveResource(fromResource: String, toResourcePath: String) throws -> Void

- (void)moveResource:(NSString*)fromResource :(NSString*)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 (Dropbox Module)

Resets the component to its initial state.

Syntax

• Swift
• Objective-C

public func reset() throws -> Void

- (void)reset;

Remarks

This method resets the class to its initial state.

RestoreResource Method (Dropbox Module)

Restores a given file resource revision.

Syntax

• Swift
• Objective-C

public func restoreResource(revision: String, toResourcePath: String) throws -> String

- (NSString*)restoreResource:(NSString*)revision :(NSString*)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 (Dropbox Module)

Revokes a shared link.

Syntax

• Swift
• Objective-C

public func revokeLink(sharedLink: String) throws -> Void

- (void)revokeLink:(NSString*)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 (Dropbox Module)

Searches for resources.

Syntax

• Swift
• Objective-C

public func search(folderResource: String, query: String) throws -> Void

- (void)search:(NSString*)folderResource :(NSString*)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 Resource* 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 Resource* properties.

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

SendCustomRequest Method (Dropbox Module)

Sends a custom request to the Dropbox API.

Syntax

• Swift
• Objective-C

public func sendCustomRequest(httpMethod: String, requestPath: String, requestBody: String) throws -> Void

- (void)sendCustomRequest:(NSString*)httpMethod :(NSString*)requestPath :(NSString*)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 QueryParam* 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 ParsedHeader* 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 (Dropbox Module)

Uploads a file resource.

Syntax

• Swift
• Objective-C

public func uploadFile(newFileResource: String) throws -> String

- (NSString*)uploadFile:(NSString*)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 , then a new file resource is created with a unique name that contains "conflicted copy".
   • If RenameIfExists is , then the upload fails.
3. Otherwise, if RenameIfExists is , then a new file resource is created with a unique name.
4. Otherwise, if Overwrite is , 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 . 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 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 (Dropbox Module)

Waits a certain amount of time for changes to occur.

Syntax

• Swift
• Objective-C

public func waitForChanges(timeout: Int32) throws -> Bool

- (BOOL)waitForChanges:(int)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 ; otherwise returns .

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 , 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 (Dropbox Module)

This event fires when a document finishes transferring.

Syntax

• Swift
• Objective-C

func onEndTransfer(direction: Int32)

- (void)onEndTransfer:(int)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 (Dropbox Module)

Fired when information is available about errors during data delivery.

Syntax

• Swift
• Objective-C

func onError(errorCode: Int32, description: String)

- (void)onError:(int)errorCode :(NSString*)description;

Remarks

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

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 (Dropbox Module)

Fires after each fragment of a resumable upload is completed.

Syntax

• Swift
• Objective-C

func onFragmentComplete(fragmentNumber: Int32, fragmentCount: Int32, interrupt: inout Bool)

- (void)onFragmentComplete:(int)fragmentNumber :(int)fragmentCount :(int*)interrupt;

Remarks

When UseResumableUpload is 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 to interrupt the upload. The upload may be resumed later.

Header Event (Dropbox Module)

This event is fired every time a header line comes in.

Syntax

• Swift
• Objective-C

func onHeader(field: String, value: String)

- (void)onHeader:(NSString*)field :(NSString*)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 (Dropbox Module)

This event fires once for each log message.

Syntax

• Swift
• Objective-C

func onLog(logLevel: Int32, message: String, logType: String)

- (void)onLog:(int)logLevel :(NSString*)message :(NSString*)logType;

Remarks

This event fires 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:

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 (Dropbox Module)

Fires during an upload or download to indicate transfer progress.

Syntax

• Swift
• Objective-C

func onProgress(direction: Int32, bytesTransferred: Int64, totalBytes: Int64, percentDone: Int32)

- (void)onProgress:(int)direction :(long long)bytesTransferred :(long long)totalBytes :(int)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 (Dropbox Module)

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

Syntax

• Swift
• Objective-C

func onResourceList(id: String, name: String, path: String, resourceType: Int32, modifiedTime: String, size: Int64, accessType: Int32, revision: String, hash: String, deleted: Bool)

- (void)onResourceList:(NSString*)id :(NSString*)name :(NSString*)path :(int)resourceType :(NSString*)modifiedTime :(long long)size :(int)accessType :(NSString*)revision :(NSString*)hash :(BOOL)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:

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:

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 (Dropbox Module)

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

Syntax

• Swift
• Objective-C

func onSharedLinkList(url: String, name: String, id: String, path: String, resourceType: Int32, visibility: Int32, expires: String)

- (void)onSharedLinkList:(NSString*)URL :(NSString*)name :(NSString*)id :(NSString*)path :(int)resourceType :(int)visibility :(NSString*)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:

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

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 (Dropbox Module)

Fired after the server presents its certificate to the client.

Syntax

• Swift
• Objective-C

func onSSLServerAuthentication(certEncoded: Data, certSubject: String, certIssuer: String, status: String, accept: inout Bool)

- (void)onSSLServerAuthentication:(NSData*)certEncoded :(NSString*)certSubject :(NSString*)certIssuer :(NSString*)status :(int*)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 (Dropbox Module)

Fired when secure connection progress messages are available.

Syntax

• Swift
• Objective-C

func onSSLStatus(message: String)

- (void)onSSLStatus:(NSString*)message;

Remarks

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

StartTransfer Event (Dropbox Module)

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

Syntax

• Swift
• Objective-C

func onStartTransfer(direction: Int32)

- (void)onStartTransfer:(int)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 (Dropbox Module)

This event is fired while a document transfers (delivers document).

Syntax

• Swift
• Objective-C

func onTransfer(direction: Int32, bytesTransferred: Int64, percentDone: Int32, text: Data)

- (void)onTransfer:(int)direction :(long long)bytesTransferred :(int)percentDone :(NSData*)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.
