The AzureFile class provides an easy to use interface to Microsoft's Azure File Storage service.

Syntax

AzureFile

Remarks

The AzureFile class offers an easy-to-use API for the Microsoft Azure File Storage service. Capabilities include uploading and downloading files, strong encryption support, creating folders, file manipulation, and more.

Authentication

Authentication is simple, set the Account property to the name of the Azure Storage account to operate against, and set the AccessKey property to an Azure access key associated with that account.

Addressing Resources

Azure File Storage accounts can contain one or more file shares. Use the ListShares method to list available shares, and select which one the class should operate against using the Share property.

After selecting a share, address the files and folders within it using Linux-style absolute paths. Unless otherwise specified, the class always works in terms of absolute paths, and will always prepend a forward slash (/) to any path passed to it that does not already start with one.

Listing Directory Contents

ListResources lists resources (files and folders) within the specified directory. Calling this method will fire the ResourceList event once for each resource, and will also populate the Resource* properties. // ResourceList event handler. azurefile.OnResourceList += (s, e) => { Console.WriteLine(e.Name); }; azurefile.Share = "myshare"; do { azurefile.ListResources("/work_files/serious_business/cats"); for (int i = 0; i < azurefile.Resources.Count; i++) { // Process resources here. } } while (!string.IsNullOrEmpty(azurefile.ResourceMarker));

Downloading Files

The DownloadFile method downloads files.

If a stream has been specified using SetDownloadStream, the file data will be sent through it. If a stream is not specified, and 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: azurefile.LocalFile = "../MyFile.zip"; azurefile.DownloadFile(azurefile.Resources[0].Path);

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"; azurefile.LocalFile = downloadFile; azurefile.DownloadFile(azurefile.Resources[0].Path); //The transfer is interrupted and DownloadFile() above fails. Later, resume the download: //Get the size of the partially downloaded file azurefile.StartByte = new FileInfo(downloadFile).Length; azurefile.DownloadFile(azurefile.Resources[0].Path);

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. azurefile.LocalFile = "../MyFile.zip"; azurefile.EncryptionPassword = "password"; azurefile.DownloadFile(azurefile.Resources[0].Path); //The transfer is interrupted and DownloadFile() above fails. Later, resume the download: //Get the size of the partially download temp file azurefile.StartByte = new FileInfo(azurefile.Config("DownloadTempFile")).Length; azurefile.DownloadFile(azurefile.Resources[0].Path);

Uploading Files

The UploadFile method uploads new files.

If SetUploadStream has been used to set an upload stream, it will take priority as the file data source. 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

The UploadFile method is a convenience method that performs a resumable file upload. When called, the class first uses CreateFile to initialize a new file entry on the server; and then it fragments the file data into smaller pieces and calls PutRange multiple times in succession to upload those fragments. The fragment size is fixed at 4MB (this is a server limitation that cannot be changed).

During the 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 StartByte is populated (if the same instance of the class is used, they should already be populated, and no special action should be needed). If uploading from a stream, be sure to reset its position to where it was the first time the upload was started (typically the beginning). Then call UploadFile again to resume the upload at the specified StartByte offset. azurefile.LocalFile = "../MyFile.zip"; azurefile.UploadFile("MyFile.zip"); //The transfer is interrupted and UploadFile() above fails. Later, resume the download. //Using the same instance StartByte is already populated from the previous upload attempt. azurefile.UploadFile("MyFile.zip"); MemoryStream uploadStream = new MemoryStream(File.ReadAllBytes("../MyFile.zip")); azurefile.SetUploadStream(uploadStream); azurefile.UploadFile("MyFile.zip"); //The transfer is interrupted and UploadFile() above fails. Later, resume the download. //Using the same instance StartByte is already populated from the previous upload attempt. //You MUST reset the stream's position to where it was when you first started the upload! uploadStream.Position = 0; azurefile.UploadFile("MyFile.zip");

Additional Functionality

LocalHost Property (AzureFile Class)

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

Syntax

ANSI (Cross Platform)
char* GetLocalHost();
int SetLocalHost(const char* lpszLocalHost); Unicode (Windows) LPWSTR GetLocalHost();

int SetLocalHost(QString qsLocalHost);

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.

Default Value

0

Remarks

This is the type of certificate store for this certificate.

The class supports both public and private keys in a variety of formats. When the cstAuto value is used, the class will automatically determine the type. This property can take one of the following values:

0 (cstUser - 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 (cstMachine)For Windows, this specifies that the certificate store is a machine store.

Note: This store type is not available in Java.

2 (cstPFXFile)The certificate store is the name of a PFX (PKCS#12) file containing certificates.
3 (cstPFXBlob)The certificate store is a string (binary or Base64-encoded) representing a certificate store in PFX (PKCS#12) format.
4 (cstJKSFile)The certificate store is the name of a Java Key Store (JKS) file containing certificates.

Note: This store type is only available in Java.

5 (cstJKSBlob)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 only available in Java.

6 (cstPEMKeyFile)The certificate store is the name of a PEM-encoded file that contains a private key and an optional certificate.
7 (cstPEMKeyBlob)The certificate store is a string (binary or Base64-encoded) that contains a private key and an optional certificate.
8 (cstPublicKeyFile)The certificate store is the name of a file that contains a PEM- or DER-encoded public key certificate.
9 (cstPublicKeyBlob)The certificate store is a string (binary or Base64-encoded) that contains a PEM- or DER-encoded public key certificate.
10 (cstSSHPublicKeyBlob)The certificate store is a string (binary or Base64-encoded) that contains an SSH-style public key.
11 (cstP7BFile)The certificate store is the name of a PKCS#7 file containing certificates.
12 (cstP7BBlob)The certificate store is a string (binary) representing a certificate store in PKCS#7 format.
13 (cstSSHPublicKeyFile)The certificate store is the name of a file that contains an SSH-style public key.
14 (cstPPKFile)The certificate store is the name of a file that contains a PPK (PuTTY Private Key).
15 (cstPPKBlob)The certificate store is a string (binary) that contains a PPK (PuTTY Private Key).
16 (cstXMLFile)The certificate store is the name of a file that contains a certificate in XML format.
17 (cstXMLBlob)The certificate store is a string that contains a certificate in XML format.

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

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 SSLCertStore and set SSLCertStorePassword 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.

Data Type

Integer

SSLCertSubject Property (AzureFile Class)

This is the subject of the certificate used for client authentication.

Syntax

ANSI (Cross Platform)
char* GetSSLCertSubject();
int SetSSLCertSubject(const char* lpszSSLCertSubject); Unicode (Windows) LPWSTR GetSSLCertSubject();
INT SetSSLCertSubject(LPCWSTR lpszSSLCertSubject);
char* cloudstorage_azurefile_getsslcertsubject(void* lpObj);
int cloudstorage_azurefile_setsslcertsubject(void* lpObj, const char* lpszSSLCertSubject);
QString GetSSLCertSubject();
int SetSSLCertSubject(QString qsSSLCertSubject);

Default Value

""

Remarks

This is the subject of the certificate used for client authentication.

This property must be set after all other certificate properties are set. When this property is set, a search is performed in the current certificate store to locate a certificate with a matching subject.

If a matching certificate is found, the property is set to the full subject of the matching certificate.

If an exact match is not found, the store is searched for subjects containing the value of the property.

If a match is still not found, the property is set to an empty string, and no certificate is selected.

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

SSLP_INTERNAL(2)
int cloudstorage_azurefile_getsslprovider(void* lpObj);
int cloudstorage_azurefile_setsslprovider(void* lpObj, int iSSLProvider);
int GetSSLProvider();
int SetSSLProvider(int iSSLProvider);

Default Value

0

Remarks

This property specifies the SSL/TLS implementation to use. In most cases the default value of 0 (Automatic) is recommended and should not be changed. When set to 0 (Automatic) the class will select whether to use the platform implementation or the internal implementation depending on the operating system as well as the TLS version being used.

Possible values are:

0 (sslpAutomatic - default)Automatically selects the appropriate implementation.
1 (sslpPlatform) Uses the platform/system implementation.
2 (sslpInternal) Uses the internal implementation.
Additional Notes

In most cases using the default value (Automatic) is recommended. The class will select a provider depending on the current platform.

When Automatic is selected, on Windows the class will use the platform implementation. On Linux/macOS the class will use the internal implementation. When TLS 1.3 is enabled via SSLEnabledProtocols the internal implementation is used on all platforms.

Data Type

Integer

SSLServerCertEncoded Property (AzureFile Class)

This is the certificate (PEM/Base64 encoded).

Syntax

ANSI (Cross Platform)
int GetSSLServerCertEncoded(char* &lpSSLServerCertEncoded, int &lenSSLServerCertEncoded);

Unicode (Windows)
INT GetSSLServerCertEncoded(LPSTR &lpSSLServerCertEncoded, INT &lenSSLServerCertEncoded);
int cloudstorage_azurefile_getsslservercertencoded(void* lpObj, char** lpSSLServerCertEncoded, int* lenSSLServerCertEncoded);
QByteArray GetSSLServerCertEncoded();

Default Value

""

Remarks

This is the certificate (PEM/Base64 encoded). This property is used to assign a specific certificate. The SSLServerCertStore and SSLServerCertSubject properties also may be used to specify a certificate.

When SSLServerCertEncoded is set, a search is initiated in the current SSLServerCertStore for the private key of the certificate. If the key is found, SSLServerCertSubject is updated to reflect the full subject of the selected certificate; otherwise, SSLServerCertSubject is set to an empty string.

This property is read-only and not available at design time.

Data Type

Binary String

StartByte Property (AzureFile Class)

The byte offset from which to start the upload or download.

Syntax

ANSI (Cross Platform)
int64 GetStartByte();
int SetStartByte(int64 lStartByte); Unicode (Windows) LONG64 GetStartByte();
INT SetStartByte(LONG64 lStartByte);
int64 cloudstorage_azurefile_getstartbyte(void* lpObj);
int cloudstorage_azurefile_setstartbyte(void* lpObj, int64 lStartByte);
qint64 GetStartByte();
int SetStartByte(qint64 lStartByte);

Default Value

0

Remarks

This property may be set to resume an upload or download; it specifies the offset in the file (or stream, when uploading) from which to resume. See UploadFile and DownloadFile for details about resuming uploads and downloads.

When uploading from a stream, the class will always seek forward in the stream if the value of StartByte is greater than 0 when UploadFile is called. Keep this in mind when resuming interrupted uploads.

This property is not available at design time.

Data Type

Long64

Timeout Property (AzureFile Class)

A timeout for the class.

Syntax

ANSI (Cross Platform)
int GetTimeout();
int SetTimeout(int iTimeout); Unicode (Windows) INT GetTimeout();
INT SetTimeout(INT iTimeout);
int cloudstorage_azurefile_gettimeout(void* lpObj);
int cloudstorage_azurefile_settimeout(void* lpObj, int iTimeout);
int GetTimeout();
int SetTimeout(int iTimeout);

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.

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.

Data Type

Integer

UseSSL Property (AzureFile Class)

Whether to use SSL/TLS when connecting.

Syntax

ANSI (Cross Platform)

int cloudstorage_azurefile_abortcopy(void* lpObj, const char* lpszDestFilePath, const char* lpszCopyId);
int AbortCopy(const QString& qsDestFilePath, const QString& qsCopyId);

Remarks

This method aborts the copy operation identified by the given CopyId for the destination file at DestFilePath in the share currently selected by Share.

Note that the destination file will still exist after aborting a copy operation, but it will be empty.

Error Handling (C++)

This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)

AddMetadata Method (AzureFile Class)

Adds a metadata item to the Metadata properties.

Syntax

ANSI (Cross Platform)
int AddMetadata(const char* lpszName, const char* lpszValue);

Unicode (Windows)
INT AddMetadata(LPCWSTR lpszName, LPCWSTR lpszValue);
int cloudstorage_azurefile_addmetadata(void* lpObj, const char* lpszName, const char* lpszValue);
int AddMetadata(const QString& qsName, const QString& qsValue);

Remarks

This method adds a metadata item to the Metadata properties. Name specifies the name of the item, and Value specifies the value of the item.

Note that the class will automatically prepend x-ms-meta- to metadata item names (as necessary) when they are submitted to the server. Also note that while metadata item names are case-preserving, they are not case-sensitive.

Error Handling (C++)

This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)

AddQueryParam Method (AzureFile Class)

Adds a query parameter to the QueryParams properties.

Syntax

ANSI (Cross Platform)
int AddQueryParam(const char* lpszName, const char* lpszValue);

Unicode (Windows)
INT AddQueryParam(LPCWSTR lpszName, LPCWSTR lpszValue);
int cloudstorage_azurefile_addqueryparam(void* lpObj, const char* lpszName, const char* lpszValue);
int AddQueryParam(const QString& qsName, const QString& qsValue);

Remarks

This method is used to add a query parameter to the QueryaParam* 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.

Error Handling (C++)

This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)

ClearRange Method (AzureFile Class)

Clears a range of bytes from a file.

Syntax

ANSI (Cross Platform)
int ClearRange(const char* lpszFilePath, int64 lFirst, int64 lLast);

Unicode (Windows)
INT ClearRange(LPCWSTR lpszFilePath, LONG64 lFirst, LONG64 lLast);
int cloudstorage_azurefile_clearrange(void* lpObj, const char* lpszFilePath, int64 lFirst, int64 lLast);
int ClearRange(const QString& qsFilePath, qint64 lFirst, qint64 lLast);

Remarks

This method clears the range of bytes from First to Last (inclusive) from the file at FilePath in the share currently selected by Share.

The server tracks ranges of file data in 512-byte chunks, aligned to the absolute beginning of the file. When this method is called, the server frees any such chunks that are completely covered by the specified range of bytes ([First]-[Last]), and writes 0s to the appropriate portions of any chunks which are not completely covered by that range.

Freed chunks are not included in the results returned by GetRanges.

Error Handling (C++)

This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)

Config Method (AzureFile Class)

Sets or retrieves a configuration setting.

Syntax

ANSI (Cross Platform)
char* Config(const char* lpszConfigurationString);

Unicode (Windows)
LPWSTR Config(LPCWSTR lpszConfigurationString);
char* cloudstorage_azurefile_config(void* lpObj, const char* lpszConfigurationString);
QString Config(const QString& qsConfigurationString);

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.

Error Handling (C++)

This method returns a String value; after it returns, call the GetLastErrorCode() method to obtain its result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message.

CopyFile Method (AzureFile Class)

Copies a file.

Syntax

ANSI (Cross Platform)
char* CopyFile(const char* lpszFromFilePath, const char* lpszToFilePath, const char* lpszToShare);

Unicode (Windows)
LPWSTR CopyFile(LPCWSTR lpszFromFilePath, LPCWSTR lpszToFilePath, LPCWSTR lpszToShare);
char* cloudstorage_azurefile_copyfile(void* lpObj, const char* lpszFromFilePath, const char* lpszToFilePath, const char* lpszToShare);
QString CopyFile(const QString& qsFromFilePath, const QString& qsToFilePath, const QString& qsToShare);

Remarks

This method copies the file at FromFilePath (in the share currently selected by Share) to the path ToFilePath in the share ToShare. If this method finishes successfully, it will either return an asynchronous copy operation Id, or an empty string (if the copy has finished already).

If ToShare is empty, the current value of Share will be used instead. If ToShare is non-empty, the value will automatically be lowercased when preparing the request.

Any parent folders included in ToFilePath must already exist.

If the destination file already exists, it will be overwritten.

As long as the server doesn't return an error, this method will always populate the CopyId and CopyStatus configuration settings (and clear CopyProgress and CopyStatusDesc).

Asynchronous Copy Notes

As mentioned, this method will return a copy operation Id if the copy operation was started asynchronously. In this case, use the GetFileInfo method to poll the destination file's information, which will cause the CopyStatus, CopyStatusDesc, and CopyProgress configuration settings to be refreshed.

A copy operation whose CopyStatus is still pending may also be aborted by passing the copy operation Id returned by this method (or later retrieved from CopyId) to the AbortCopy method. // Copy a file to another location within the same share. string copyResult = azurefile.CopyFile("/folder1/important.zip", "/folder2/secrets.zip", ""); // If the returned value *isn't* empty string, then we'll monitor the status of the // asynchronous copy operation by polling once every 2 seconds using GetFileInfo(). if (!string.IsNullOrEmpty(copyResult)) { do { azurefile.GetFileInfo("/folder2/secrets.zip"); Console.WriteLine("Copy progress: " + azurefile.Config("CopyProgress")); } while (azurefile.Config("CopyStatus") == "pending"); }

Error Handling (C++)

This method returns a String value; after it returns, call the GetLastErrorCode() method to obtain its result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message.

CreateFile Method (AzureFile Class)

Syntax

ANSI (Cross Platform)
char* CreateFile(const char* lpszNewFilePath, int64 lFileLength);

Unicode (Windows)
LPWSTR CreateFile(LPCWSTR lpszNewFilePath, LONG64 lFileLength);
char* cloudstorage_azurefile_createfile(void* lpObj, const char* lpszNewFilePath, int64 lFileLength);
QString CreateFile(const QString& qsNewFilePath, qint64 lFileLength);

Remarks

This method initializes a new file with a given FileLength (in bytes) at the specified NewFilePath in the share currently selected by Share. The path of the newly-initialized file is returned.

Any parent folders included in NewFilePath must already exist.

If the SendMetadata configuration setting is enabled when this method is called, all items in the Metadata* properties will be sent along with the creation request.

Note: This method is typically only useful for advanced use-cases. To upload a file, just call UploadFile.

Usage Notes

This method does not upload or otherwise allocate any data, it just creates the file entry and "reserves" storage space for it. After a file has been created with this method, the following methods can be used to manipulate its data:

  • The PutRange method can be used to upload ranges of data (up to 4MB at once) to the file.
  • The ClearRange method can be used to clear an arbitrary range of data from the file, allowing the server to release the associated storage resources.
  • The GetRanges method can be used to obtain a list of all data ranges present in the file.

Error Handling (C++)

This method returns a String value; after it returns, call the GetLastErrorCode() method to obtain its result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message.

CreateFolder Method (AzureFile Class)

If the CreateShareQuota configuration setting is a positive, non-zero integer when this method is called, the share will be created with a space quota of that many GB. A share's space quota may be changed at any time using the SetShareQuota method.

If the SendMetadata configuration setting is enabled when this method is called, all items in the Metadata* properties will be sent along with the creation request.

Share Name Rules

Share names must adhere to the following rules:

  • Must be 3 to 63 characters long.
  • Must start with a letter or number; and may only contain letters, numbers, and hyphens.
  • All letters much be lowercase. (For convenience, the class will automatically lowercase all letters in any value assigned to Share.)
  • All hyphens must be immediately preceded and followed by a letter or number (consecutive hyphens are not allowed).

Error Handling (C++)

This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution.

Unicode (Windows)
INT DeleteShare();
int cloudstorage_azurefile_deleteshare(void* lpObj);
int DeleteShare();

Remarks

This method deletes the share currently selected by the Share property.

If the currently selected Share has any snapshots associated with it, and the DeleteShareSnapshots configuration setting is disabled (default) when this method is called, the server will return an error. Shares with snapshots can only be deleted after enabling DeleteShareSnapshots.

Note that, according to the Azure File Storage documentation, a share's name cannot be reused until at least 30 seconds after its deletion.

Error Handling (C++)

This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message.

DownloadFile Method (AzureFile Class)

Downloads a file.

Syntax

ANSI (Cross Platform)
int DownloadFile(const char* lpszFilePath);

Unicode (Windows)
INT DownloadFile(LPCWSTR lpszFilePath);
int cloudstorage_azurefile_downloadfile(void* lpObj, const char* lpszFilePath);
int DownloadFile(const QString& qsFilePath);

Remarks

This method downloads the file at the specified FilePath in the share currently selected by Share.

If a stream has been specified using SetDownloadStream, the file data will be sent through it. If a stream is not specified, and 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: azurefile.LocalFile = "../MyFile.zip"; azurefile.DownloadFile(azurefile.Resources[0].Path);

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"; azurefile.LocalFile = downloadFile; azurefile.DownloadFile(azurefile.Resources[0].Path); //The transfer is interrupted and DownloadFile() above fails. Later, resume the download: //Get the size of the partially downloaded file azurefile.StartByte = new FileInfo(downloadFile).Length; azurefile.DownloadFile(azurefile.Resources[0].Path);

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. azurefile.LocalFile = "../MyFile.zip"; azurefile.EncryptionPassword = "password"; azurefile.DownloadFile(azurefile.Resources[0].Path); //The transfer is interrupted and DownloadFile() above fails. Later, resume the download: //Get the size of the partially download temp file azurefile.StartByte = new FileInfo(azurefile.Config("DownloadTempFile")).Length; azurefile.DownloadFile(azurefile.Resources[0].Path);

Error Handling (C++)

This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)

GetLink Method (AzureFile Class)

Creates a link that provides access to a share or file.

Syntax

Remarks

This method creates and returns a shared access signature (SAS), which is a link that provides access to a specific share or file. The following table indicates which inputs must be provided to produce a link of the desired type:

Link TypeRequired Inputs
Share Non-empty Share, empty FilePath
File Non-empty Share and FilePath

Permissions specifies what permissions the SAS grants, in the form of an abbreviated permissions list. Refer to this section of Azure's "Create a Service SAS" article for more information about how to format this value.

StartTime and ExpiryTime specify the UTC start and end times of the SAS's validity interval. Refer to this section of Azure's "Create a Service SAS" article for more information about how to format these values.

StartTime may be empty, in which case the server will assume that the link is valid immediately. Permissions and ExpiryTime must both be non-empty, unless an si query parameter that references a stored access policy (which has corresponding non-empty values) is present in the QueryParam* properties.

If any of the query parameters listed below are present in the QueryParam* properties when this method is called, they will be included when creating the SAS. All other application-specified query parameters are ignored.

  • Response headers: rscc, rscd, rsce, rscl, rsct
  • IP address (single or range): sip
  • Allowed HTTP protocol(s): spr
  • Stored access policy ("signed identifier"): si

For more information about SAS links, refer to Azure's Create a Service SAS article.

Error Handling (C++)

This method returns a String value; after it returns, call the GetLastErrorCode() method to obtain its result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message.

GetRanges Method (AzureFile Class)

Gets the list of allocated data ranges in a file.

Syntax

ANSI (Cross Platform)
int GetRanges(const char* lpszFilePath);

Unicode (Windows)
INT GetRanges(LPCWSTR lpszFilePath);
int cloudstorage_azurefile_getranges(void* lpObj, const char* lpszFilePath);
int GetRanges(const QString& qsFilePath);

Remarks

This method gets the list of allocated data ranges in the file at the specified FilePath in the share currently selected by Share and populates the Range* properties with the results.

The server tracks ranges of file data in 512-byte chunks, aligned to the absolute beginning of the file; thus, the size of every range returned by this method will always be a multiple of 512. Chunks that are not currently allocated (either because no data has been written to them, or because they've been freed with ClearRange) will not be returned by this method.

Error Handling (C++)

This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)

GetShareInfo Method (AzureFile Class)

Unicode (Windows)
INT GetShareInfo();
int cloudstorage_azurefile_getshareinfo(void* lpObj);
int GetShareInfo();

Remarks

This method gets information and metadata for the share currently selected by the Share property.

Calling this method will fire the ShareList event, will re-populate the Share* properties with a single item, and will re-populate the Metadata* properties with any metadata currently associated with the share.

Error Handling (C++)

This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)

Interrupt Method (AzureFile Class)

Interrupt the current method.

Syntax

ANSI (Cross Platform)
int Interrupt();

Remarks

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

Error Handling (C++)

This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)

ListResources Method (AzureFile Class)

Lists resources in a given folder.

Syntax

ANSI (Cross Platform)
int ListResources(const char* lpszFolderPath);

Unicode (Windows)
INT ListResources(LPCWSTR lpszFolderPath);
int cloudstorage_azurefile_listresources(void* lpObj, const char* lpszFolderPath);
int ListResources(const QString& qsFolderPath);

Remarks

This method lists the resources in the folder at the specified FolderPath in the share currently selected by Share.

Before calling this method, the Prefix property may be set in order to restrict the results to only the items whose names begin with a given string. The MaxResults configuration setting may also be used to limit the number of results returned.

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.

Note that the server only returns the following resource properties when listing resources (use GetFileInfo or GetFolderInfo to retrieve all properties for a specific resource):

// ResourceList event handler. azurefile.OnResourceList += (s, e) => { Console.WriteLine(e.Name); }; azurefile.Share = "myshare"; do { azurefile.ListResources("/work_files/serious_business/cats"); for (int i = 0; i < azurefile.Resources.Count; i++) { // Process resources here. } } while (!string.IsNullOrEmpty(azurefile.ResourceMarker));

Error Handling (C++)

This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message.

Unicode (Windows)
INT ListShares();
int cloudstorage_azurefile_listshares(void* lpObj);
int ListShares();

Remarks

This method lists the shares in the file storage account specified by the Account property.

Before calling this method, the Prefix property may be set in order to restrict the results to only the items whose names begin with a given string. The MaxResults configuration setting may also be used to limit the number of results returned.

Calling this method will fire the ShareList event once for each share, and will also populate the Share* properties.

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

Note that the server does not return the shares' ShareSpaceUsed property when listing shares; use GetShareInfo to retrieve all properties for a specific share. // ShareList event handler. azurefile.OnShareList += (s, e) => { Console.WriteLine(e.Name); }; do { azurefile.ListShares(); for (int i = 0; i < azurefile.Shares.Count; i++) { // Process shares here. } } while (!string.IsNullOrEmpty(azurefile.ShareMarker));

Error Handling (C++)

This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)

PutRange Method (AzureFile Class)

Uploads a range of data to a file.

Syntax

ANSI (Cross Platform)
int PutRange(const char* lpszFilePath, int64 lWriteOffset);

int cloudstorage_azurefile_putrange(void* lpObj, const char* lpszFilePath, int64 lWriteOffset);
int PutRange(const QString& qsFilePath, qint64 lWriteOffset);

Remarks

This method uploads a range of data to the file at the specified FilePath in the share currently selected by Share. The data to upload cannot be larger than 4MB (4194304 bytes), and is written to the file at the given WriteOffset (specified in bytes).

The server tracks ranges of file data in 512-byte chunks, aligned to the absolute beginning of the file. However, neither the WriteOffset nor the length of the data to upload need be a multiple of 512. Any portions of a chunk not written to will be populated with 0s.

Note that, according to the Azure File Storage documentation, this operation requires a write lock on the entire file in order to complete successfully.

Error Handling (C++)

This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message.

Unicode (Windows)
INT SetDownloadStream(CloudStorageStream* sDownloadStream);
int cloudstorage_azurefile_setdownloadstream(void* lpObj, CloudStorageStream* sDownloadStream);
int SetDownloadStream(CloudStorageStream* sDownloadStream);

Remarks

If a download stream is set before data is downloaded, the downloaded data will be written to the stream. The stream should be open and normally set to position 0.

Note: Passing a non-null value for DownloadStream will cause LocalFile to be cleared. Similarly, setting LocalFile to a non-empty value will discard any stream set using this method.

Error Handling (C++)

This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)

SetShareQuota Method (AzureFile Class)

Sets a share's space quota.

Syntax

ANSI (Cross Platform)
int SetShareQuota(int iQuota);

Unicode (Windows)
INT SetShareQuota(INT iQuota);
int cloudstorage_azurefile_setsharequota(void* lpObj, int iQuota);
int SetShareQuota(int iQuota);

Remarks

This method sets the size, in GB, of the space quota imposed on the share currently selected by the Share property. Quota must be greater than 0.

It is legal to lower a share's quota to a value less than its current space usage. However, doing so will prevent new space from being allocated until either the space usage falls below quota or the quota is raised above the space usage.

Error Handling (C++)

This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)

SetUploadStream Method (AzureFile Class)

Sets the stream from which data is read when uploading.

Unicode (Windows)
INT SetUploadStream(CloudStorageStream* sUploadStream);
int cloudstorage_azurefile_setuploadstream(void* lpObj, CloudStorageStream* sUploadStream);
int SetUploadStream(CloudStorageStream* sUploadStream);

Remarks

If an upload stream is set before data is uploaded, the content of the stream will be read by the class and uploaded to the server. The stream should be open and normally set to position 0.

Note: Passing a non-null value for UploadStream will cause LocalFile to be cleared. Similarly, setting LocalFile to a non-empty value will discard any stream set using this method.

Error Handling (C++)

This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message.

INT UpdateMetadata(LPCWSTR lpszPath, INT iResourceType);
int cloudstorage_azurefile_updatemetadata(void* lpObj, const char* lpszPath, int iResourceType);
int UpdateMetadata(const QString& qsPath, int iResourceType);

Remarks

This method sets the metadata for a file, folder, or share to the items currently held by the Metadata* properties. The ResourceType parameter indicates the kind of resource the class should prepare the request for; possible values are:

  • 0: Set the metadata for the file at the specified Path in the share currently selected by Share.
  • 1: Set the metadata for the folder at the specified Path in the share currently selected by Share.
  • 2: Set the metadata for the share currently selected by Share (Path is ignored).

Note that it is not possible to do a partial metadata update. That is, all metadata currently associated with the remote entity will be replaced with the metadata sent in the request.

Error Handling (C++)

This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)

UploadFile Method (AzureFile Class)

Uploads a new file resource.

Syntax

ANSI (Cross Platform)
char* UploadFile(const char* lpszNewFilePath);

Unicode (Windows)
LPWSTR UploadFile(LPCWSTR lpszNewFilePath);
char* cloudstorage_azurefile_uploadfile(void* lpObj, const char* lpszNewFilePath);
QString UploadFile(const QString& qsNewFilePath);

Remarks

This method uploads a new file resource at the specified NewFilePath in the share currently selected by Share. The path of the newly-created file is returned.

Any parent folders included in NewFilePath must already exist.

If the SendMetadata configuration setting is enabled when this method is called, all items in the Metadata* properties will be sent along with the creation request.

If SetUploadStream has been used to set an upload stream, it will take priority as the file data source. 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

The UploadFile method is a convenience method that performs a resumable file upload. When called, the class first uses CreateFile to initialize a new file entry on the server; and then it fragments the file data into smaller pieces and calls PutRange multiple times in succession to upload those fragments. The fragment size is fixed at 4MB (this is a server limitation that cannot be changed).

During the 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 StartByte is populated (if the same instance of the class is used, they should already be populated, and no special action should be needed). If uploading from a stream, be sure to reset its position to where it was the first time the upload was started (typically the beginning). Then call UploadFile again to resume the upload at the specified StartByte offset. azurefile.LocalFile = "../MyFile.zip"; azurefile.UploadFile("MyFile.zip"); //The transfer is interrupted and UploadFile() above fails. Later, resume the download. //Using the same instance StartByte is already populated from the previous upload attempt. azurefile.UploadFile("MyFile.zip"); MemoryStream uploadStream = new MemoryStream(File.ReadAllBytes("../MyFile.zip")); azurefile.SetUploadStream(uploadStream); azurefile.UploadFile("MyFile.zip"); //The transfer is interrupted and UploadFile() above fails. Later, resume the download. //Using the same instance StartByte is already populated from the previous upload attempt. //You MUST reset the stream's position to where it was when you first started the upload! uploadStream.Position = 0; azurefile.UploadFile("MyFile.zip");

Error Handling (C++)

This method returns a String value; after it returns, call the GetLastErrorCode() method to obtain its result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message.

EndTransfer Event (AzureFile Class)

This event fires when a document finishes transferring.

Syntax

ANSI (Cross Platform)
virtual int FireEndTransfer(AzureFileEndTransferEventParams *e);
typedef struct {
int Direction; int reserved; } AzureFileEndTransferEventParams;
Unicode (Windows) virtual INT FireEndTransfer(AzureFileEndTransferEventParams *e);
typedef struct {
INT Direction; INT reserved; } AzureFileEndTransferEventParams;
#define EID_AZUREFILE_ENDTRANSFER 1

virtual INT CLOUDSTORAGE_CALL FireEndTransfer(INT &iDirection);
class AzureFileEndTransferEventParams {
public:
  int Direction();

  int EventRetVal();
  void SetEventRetVal(int iRetVal);
};
// To handle, connect one or more slots to this signal. void EndTransfer(AzureFileEndTransferEventParams *e);
// Or, subclass AzureFile and override this emitter function. virtual int FireEndTransfer(AzureFileEndTransferEventParams *e) {...}

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 (AzureFile Class)

Fired when information is available about errors during data delivery.

Syntax

ANSI (Cross Platform)
virtual int FireError(AzureFileErrorEventParams *e);
typedef struct {
int ErrorCode;
const char *Description; int reserved; } AzureFileErrorEventParams;
Unicode (Windows) virtual INT FireError(AzureFileErrorEventParams *e);
typedef struct {
INT ErrorCode;
LPCWSTR Description; INT reserved; } AzureFileErrorEventParams;
#define EID_AZUREFILE_ERROR 2

virtual INT CLOUDSTORAGE_CALL FireError(INT &iErrorCode, LPSTR &lpszDescription);
class AzureFileErrorEventParams {
public:
  int ErrorCode();

  const QString &Description();

  int EventRetVal();
  void SetEventRetVal(int iRetVal);
};
// To handle, connect one or more slots to this signal. void Error(AzureFileErrorEventParams *e);
// Or, subclass AzureFile and override this emitter function. virtual int FireError(AzureFileErrorEventParams *e) {...}

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 (AzureFile Class)

Fires after each fragment of a resumable upload is completed.

Syntax

ANSI (Cross Platform)
virtual int FireFragmentComplete(AzureFileFragmentCompleteEventParams *e);
typedef struct {
int FragmentNumber;
int FragmentCount;
int Interrupt; int reserved; } AzureFileFragmentCompleteEventParams;
Unicode (Windows) virtual INT FireFragmentComplete(AzureFileFragmentCompleteEventParams *e);
typedef struct {
INT FragmentNumber;
INT FragmentCount;
BOOL Interrupt; INT reserved; } AzureFileFragmentCompleteEventParams;
#define EID_AZUREFILE_FRAGMENTCOMPLETE 3

virtual INT CLOUDSTORAGE_CALL FireFragmentComplete(INT &iFragmentNumber, INT &iFragmentCount, BOOL &bInterrupt);
class AzureFileFragmentCompleteEventParams {
public:
  int FragmentNumber();

  int FragmentCount();

  bool Interrupt();
  void SetInterrupt(bool bInterrupt);

  int EventRetVal();
  void SetEventRetVal(int iRetVal);
};
// To handle, connect one or more slots to this signal. void FragmentComplete(AzureFileFragmentCompleteEventParams *e);
// Or, subclass AzureFile and override this emitter function. virtual int FireFragmentComplete(AzureFileFragmentCompleteEventParams *e) {...}

Remarks

When 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 begins 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 (AzureFile Class)

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

Syntax

ANSI (Cross Platform)
virtual int FireHeader(AzureFileHeaderEventParams *e);
typedef struct {
const char *Field;
const char *Value; int reserved; } AzureFileHeaderEventParams;
Unicode (Windows) virtual INT FireHeader(AzureFileHeaderEventParams *e);
typedef struct {
LPCWSTR Field;
LPCWSTR Value; INT reserved; } AzureFileHeaderEventParams;
#define EID_AZUREFILE_HEADER 4

virtual INT CLOUDSTORAGE_CALL FireHeader(LPSTR &lpszField, LPSTR &lpszValue);
class AzureFileHeaderEventParams {
public:
  const QString &Field();

  const QString &Value();

  int EventRetVal();
  void SetEventRetVal(int iRetVal);
};
// To handle, connect one or more slots to this signal. void Header(AzureFileHeaderEventParams *e);
// Or, subclass AzureFile and override this emitter function. virtual int FireHeader(AzureFileHeaderEventParams *e) {...}

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 (AzureFile Class)

This event fires once for each log message.

Syntax

ANSI (Cross Platform)
virtual int FireLog(AzureFileLogEventParams *e);
typedef struct {
int LogLevel;
const char *Message;
const char *LogType; int reserved; } AzureFileLogEventParams;
Unicode (Windows) virtual INT FireLog(AzureFileLogEventParams *e);
typedef struct {
INT LogLevel;
LPCWSTR Message;
LPCWSTR LogType; INT reserved; } AzureFileLogEventParams;
#define EID_AZUREFILE_LOG 5

virtual INT CLOUDSTORAGE_CALL FireLog(INT &iLogLevel, LPSTR &lpszMessage, LPSTR &lpszLogType);
class AzureFileLogEventParams {
public:
  int LogLevel();

  const QString &Message();

  const QString &LogType();

  int EventRetVal();
  void SetEventRetVal(int iRetVal);
};
// To handle, connect one or more slots to this signal. void Log(AzureFileLogEventParams *e);
// Or, subclass AzureFile and override this emitter function. virtual int FireLog(AzureFileLogEventParams *e) {...}

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:

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 (AzureFile Class)

Fires during an upload or download to indicate transfer progress.

Syntax

ANSI (Cross Platform)
virtual int FireProgress(AzureFileProgressEventParams *e);
typedef struct {
int Direction;
int64 BytesTransferred;
int64 TotalBytes;
int PercentDone; int reserved; } AzureFileProgressEventParams;
Unicode (Windows) virtual INT FireProgress(AzureFileProgressEventParams *e);
typedef struct {
INT Direction;
LONG64 BytesTransferred;
LONG64 TotalBytes;
INT PercentDone; INT reserved; } AzureFileProgressEventParams;
#define EID_AZUREFILE_PROGRESS 6

virtual INT CLOUDSTORAGE_CALL FireProgress(INT &iDirection, LONG64 &lBytesTransferred, LONG64 &lTotalBytes, INT &iPercentDone);
class AzureFileProgressEventParams {
public:
  int Direction();

  qint64 BytesTransferred();

  qint64 TotalBytes();

  int PercentDone();

  int EventRetVal();
  void SetEventRetVal(int iRetVal);
};
// To handle, connect one or more slots to this signal. void Progress(AzureFileProgressEventParams *e);
// Or, subclass AzureFile and override this emitter function. virtual int FireProgress(AzureFileProgressEventParams *e) {...}

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 (AzureFile Class)

Fires once for each resource returned when listing resources.

Syntax

ANSI (Cross Platform)
virtual int FireResourceList(AzureFileResourceListEventParams *e);
typedef struct {
const char *Name;
const char *Path;
const char *Share;
int ResourceType;
const char *ModifiedTime;
int64 Size;
const char *ETag; int reserved; } AzureFileResourceListEventParams;

  void SetEventRetVal(int iRetVal);
};
// To handle, connect one or more slots to this signal. void ResourceList(AzureFileResourceListEventParams *e);
// Or, subclass AzureFile and override this emitter function. virtual int FireResourceList(AzureFileResourceListEventParams *e) {...}

Remarks

This event fires once for each resource returned when ListResources, GetFileInfo, or GetFolderInfo is called.

Name is the name of the resource.

Path is the full path of the resource (not including the share).

Share is the name of the share the resource resides in.

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

0 (afrtFile) A file.
1 (afrtFolder) A folder.

ModifiedTime is the last modified time of the resource, formatted according to RFC 1123. (Note: this parameter is not populated by calls to ListResources.)

Size is the size of the file. Always 0 for folders.

ETag is the ETag of the resource. (Note: this parameter is not populated by calls to ListResources.)

ShareList Event (AzureFile Class)

Fires once for each share returned when listing shares.

Syntax

ANSI (Cross Platform)
virtual int FireShareList(AzureFileShareListEventParams *e);
typedef struct {
const char *Name;
const char *ModifiedTime;
const char *ETag;
int Quota; int reserved; } AzureFileShareListEventParams;
Unicode (Windows) virtual INT FireShareList(AzureFileShareListEventParams *e);
typedef struct {
LPCWSTR Name;
LPCWSTR ModifiedTime;
LPCWSTR ETag;
INT Quota; INT reserved; } AzureFileShareListEventParams;
#define EID_AZUREFILE_SHARELIST 8

virtual INT CLOUDSTORAGE_CALL FireShareList(LPSTR &lpszName, LPSTR &lpszModifiedTime, LPSTR &lpszETag, INT &iQuota);
class AzureFileShareListEventParams {
public:
  const QString &Name();

  const QString &ModifiedTime();

  const QString &ETag();

  int Quota();

  int EventRetVal();
  void SetEventRetVal(int iRetVal);
};
// To handle, connect one or more slots to this signal. void ShareList(AzureFileShareListEventParams *e);
// Or, subclass AzureFile and override this emitter function. virtual int FireShareList(AzureFileShareListEventParams *e) {...}

Remarks

This event fires once for each share returned when ListShares or GetShareInfo is called.

Name is the name of the share.

ModifiedTime is the last modified time of the share, formatted according to RFC 1123.

ETag is the ETag of the share.

Quota is the share's space quota, in GB.

SSLServerAuthentication Event (AzureFile Class)

Fired after the server presents its certificate to the client.

Syntax

ANSI (Cross Platform)
virtual int FireSSLServerAuthentication(AzureFileSSLServerAuthenticationEventParams *e);
typedef struct {
const char *CertEncoded; int lenCertEncoded;
const char *CertSubject;
const char *CertIssuer;
const char *Status;
int Accept; int reserved; } AzureFileSSLServerAuthenticationEventParams;
Unicode (Windows) virtual INT FireSSLServerAuthentication(AzureFileSSLServerAuthenticationEventParams *e);
typedef struct {
LPCSTR CertEncoded; INT lenCertEncoded;
LPCWSTR CertSubject;
LPCWSTR CertIssuer;
LPCWSTR Status;
BOOL Accept; INT reserved; } AzureFileSSLServerAuthenticationEventParams;
#define EID_AZUREFILE_SSLSERVERAUTHENTICATION 9

virtual INT CLOUDSTORAGE_CALL FireSSLServerAuthentication(LPSTR &lpCertEncoded, INT &lenCertEncoded, LPSTR &lpszCertSubject, LPSTR &lpszCertIssuer, LPSTR &lpszStatus, BOOL &bAccept);
class AzureFileSSLServerAuthenticationEventParams {
public:
  const QByteArray &CertEncoded();

  const QString &CertSubject();

  const QString &CertIssuer();

  const QString &Status();

  bool Accept();
  void SetAccept(bool bAccept);

  int EventRetVal();
  void SetEventRetVal(int iRetVal);
};
// To handle, connect one or more slots to this signal. void SSLServerAuthentication(AzureFileSSLServerAuthenticationEventParams *e);
// Or, subclass AzureFile and override this emitter function. virtual int FireSSLServerAuthentication(AzureFileSSLServerAuthenticationEventParams *e) {...}

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 (AzureFile Class)

Fired when secure connection progress messages are available.

Syntax

ANSI (Cross Platform)
virtual int FireSSLStatus(AzureFileSSLStatusEventParams *e);
typedef struct {
const char *Message; int reserved; } AzureFileSSLStatusEventParams;
Unicode (Windows) virtual INT FireSSLStatus(AzureFileSSLStatusEventParams *e);
typedef struct {
LPCWSTR Message; INT reserved; } AzureFileSSLStatusEventParams;
#define EID_AZUREFILE_SSLSTATUS 10

virtual INT CLOUDSTORAGE_CALL FireSSLStatus(LPSTR &lpszMessage);
class AzureFileSSLStatusEventParams {
public:
  const QString &Message();

  int EventRetVal();
  void SetEventRetVal(int iRetVal);
};
// To handle, connect one or more slots to this signal. void SSLStatus(AzureFileSSLStatusEventParams *e);
// Or, subclass AzureFile and override this emitter function. virtual int FireSSLStatus(AzureFileSSLStatusEventParams *e) {...}

Remarks

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

StartTransfer Event (AzureFile Class)

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

Syntax

ANSI (Cross Platform)
virtual int FireStartTransfer(AzureFileStartTransferEventParams *e);
typedef struct {
int Direction; int reserved; } AzureFileStartTransferEventParams;
Unicode (Windows) virtual INT FireStartTransfer(AzureFileStartTransferEventParams *e);
typedef struct {
INT Direction; INT reserved; } AzureFileStartTransferEventParams;
#define EID_AZUREFILE_STARTTRANSFER 11

virtual INT CLOUDSTORAGE_CALL FireStartTransfer(INT &iDirection);
class AzureFileStartTransferEventParams {
public:
  int Direction();

  int EventRetVal();
  void SetEventRetVal(int iRetVal);
};
// To handle, connect one or more slots to this signal. void StartTransfer(AzureFileStartTransferEventParams *e);
// Or, subclass AzureFile and override this emitter function. virtual int FireStartTransfer(AzureFileStartTransferEventParams *e) {...}

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 (AzureFile Class)

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

Syntax

ANSI (Cross Platform)
virtual int FireTransfer(AzureFileTransferEventParams *e);
typedef struct {
int Direction;
int64 BytesTransferred;
int PercentDone;
const char *Text; int lenText; int reserved; } AzureFileTransferEventParams;
Unicode (Windows) virtual INT FireTransfer(AzureFileTransferEventParams *e);
typedef struct {
INT Direction;
LONG64 BytesTransferred;
INT PercentDone;
LPCSTR Text; INT lenText; INT reserved; } AzureFileTransferEventParams;
#define EID_AZUREFILE_TRANSFER 12

virtual INT CLOUDSTORAGE_CALL FireTransfer(INT &iDirection, LONG64 &lBytesTransferred, INT &iPercentDone, LPSTR &lpText, INT &lenText);
class AzureFileTransferEventParams {
public:
  int Direction();

  qint64 BytesTransferred();

  int PercentDone();

  const QByteArray &Text();

  int EventRetVal();
  void SetEventRetVal(int iRetVal);
};
// To handle, connect one or more slots to this signal. void Transfer(AzureFileTransferEventParams *e);
// Or, subclass AzureFile and override this emitter function. virtual int FireTransfer(AzureFileTransferEventParams *e) {...}

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.

CloudStorageStream Type

Syntax

CloudStorageStream (declared in cloudstorage.h)

Remarks

The AzureFile class includes one or more API members that take a stream object as a parameter. To use such API members, create a concrete class that implements the CloudStorageStream interface and pass the AzureFile class an instance of that concrete class.

When implementing the CloudStorageStream interface's properties and methods, they must behave as described below. If the concrete class's implementation does not behave as expected, undefined behavior may occur.

Properties

CanRead Whether the stream supports reading.

bool CanRead() { return true; }
CanSeek Whether the stream supports seeking.

bool CanSeek() { return true; }
CanWrite Whether the stream supports writing.

bool CanWrite() { return true; }
Length Gets the length of the stream, in bytes.

int64 GetLength() = 0;

Methods

Close Closes the stream, releasing all resources currently allocated for it.

void Close() {}

This method is called automatically when a CloudStorageStream object is deleted.

Flush Forces all data held by the stream's buffers to be written out to storage.

int Flush() { return 0; }

Must return 0 if flushing is successful; or -1 if an error occurs or the stream is closed. If the stream does not support writing, this method must do nothing and return 0.

Read Reads a sequence of bytes from the stream and advances the current position within the stream by the number of bytes read.

int Read(void* buffer, int count) = 0;

Buffer specifies the buffer to populate with data from the stream. Count specifies the number of bytes that should be read from the stream.

Must return the total number of bytes read into Buffer; this may be less than Count if that many bytes are not currently available, or 0 if the end of the stream has been reached. Must return -1 if an error occurs, if reading is not supported, or if the stream is closed.

Seek Sets the current position within the stream based on a particular point of origin.

int64 Seek(int64 offset, int seekOrigin) = 0;

Offset specifies the offset in the stream to seek to, relative to SeekOrigin. Valid values for SeekOrigin are:

  • 0: Seek from beginning.
  • 1: Seek from current position.
  • 2: Seek from end.

Must return the new position within the stream; or -1 if an error occurs, if seeking is not supported, or if the stream is closed (however, see note below). If -1 is returned, the current position within the stream must remain unchanged.

Note: If the stream is not closed, it must always be possible to call this method with an Offset of 0 and a SeekOrigin of 1 to obtain the current position within the stream, even if seeking is not otherwise supported.

Write Writes a sequence of bytes to the stream and advances the current position within the stream by the number of bytes written.

int Write(const void* buffer, int count) = 0;

Buffer specifies the buffer with data to write to the stream. Count specifies the number of bytes that should be written to the stream.

Must return the total number of bytes written to the stream; this may be less than Count if that many bytes could not be written. Must return -1 if an error occurs, if writing is not supported, or if the stream is closed.

Config Settings (AzureFile 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.

AzureFile Config Settings

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.

APIVersion:   The Azure Storage REST API version being used by the class.

This setting can be queried to obtain the version of the Azure Storage REST APIs being used by the class.

Note that this setting cannot be changed.

CopyId:   The Id of a copy operation.

This setting can be queried to obtain the Id of a copy operation.

This setting is populated after calling CopyFile, or after calling GetFileInfo for the destination file in a copy operation.

CopyProgress:   The progress of a copy operation.

This setting can be queried to obtain the progress of a copy operation, which is representing as the number of bytes copied out of the total number of bytes (e.g., 273/3620).

Calling CopyFile will clear this setting; call GetFileInfo for the destination file in a copy operation to populate it.

CopyStatus:   The status of a copy operation.

This setting can be queried to obtain the status of a copy operation. Possible values are:

  • pending
  • success
  • aborted
  • failed

This setting is populated after calling CopyFile, or after calling GetFileInfo for the destination file in a copy operation.

CopyStatusDesc:   The status description for a copy operation.

This setting can be queried to obtain a description of a copy operation's status. The description will vary based on the operation's current CopyStatus:

  • If the operation is pending, the description may reflect any non-fatal errors which have occurred thus far.
  • If the operation is failed, the description will detail the fatal error which caused the failure.
  • Otherwise, the description will always be empty.

Calling CopyFile will clear this setting; call GetFileInfo for the destination file in a copy operation to populate it.

CreateShareQuota:   Specifies an initial space quota to impose when creating shares.

This setting may be set to a positive, non-zero integer number to impose a space quota of that many GB when creating shares with CreateShare.

If set to 0 (default), no explicit space quota is imposed on the share when it is created. Note that a share's space quota may be changed at any time using the SetShareQuota method.

DeleteShareSnapshots:   Whether to automatically delete share snapshots when deleting a share.

This setting specifies whether a share's snapshots (if any exist) should be deleted when the share itself is deleted.

If this setting is disabled (default), calling DeleteShare will fail if the specified share has any snapshots associated with it.

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.

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.

Endpoint:   The Azure Storage endpoint suffix that the class should use.

This setting specifies the base Azure Storage endpoint suffix that the class should use. By default, the class uses the global Azure Storage endpoint, https://[ACCOUNT].[blob|file].core.windows.net (this setting controls the bolded suffix only).

In most cases, the default endpoint suffix is the correct choice. This setting should only be changed if the class needs to use an endpoint suffix associated with a specific National Cloud Deployment, in which case it should be set to one of the values shown in this table:

National Cloud Endpoint Suffix
Azure global service .core.windows.net (default)
Azure Government (US) .core.usgovcloudapi.net
Azure Germany .core.cloudapi.de
Azure China .core.chinacloudapi.cn

Please note that each National Cloud Deployment also has its own corresponding application registration portal and OAuth endpoints, both of which are completely separate from those used for/by the global Azure Storage services. Applications that wish to work with a specific National Cloud Deployment must use that National Cloud Deployment's app registration portal and OAuth endpoints to register and authenticate in order for the class to successfully communicate using the National Cloud Deployment-specific endpoint. Refer to Microsoft's National Cloud Authentication article for more information.

MaxResults:   The maximum number of results to return when listing resources or shares.

This setting specifies the maximum number of results that should be returned by a call to ListResources or ListShares.

If this setting is -1 (default), the server's default (5000) is used. Acceptable values are 1 to 5000 (inclusive).

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.

SendMetadata:   Whether to send metadata items when creating files and folders.

This setting controls whether the class will automatically submit any Metadata* items when creating shares or resources with UploadFile, CreateFile, CreateFolder, or CreateShare.

By default, this setting is disabled, and resources are not automatically created with metadata.

SendMetadataOnCopy:   Whether to send metadata items when copying files.

This setting controls whether the class will automatically submit any Metadata* items, to apply to the destination file, when CopyFile is called.

If this setting is disabled (default), or if this setting is enabled but there are no Metadata* items, then the server will copy the original metadata from the source file to the destination file.

SharedAccessSignature:   Specifies a SAS token to use for authentication.

This setting can be used to specify a URL-encoded Shared Access Signature (SAS) token that will be included in the request. To generate a Shared Access Signature for specific resources, you can use the GetLink method.

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.

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

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 via the XPath configuration setting. This configuration setting is read-only.

XChildName[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 via the XPath configuration setting. This configuration setting is read-only.

XChildXText[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 via the XPath configuration setting. This configuration setting is read-only.

XElement:   The name of the current element.

Provides the name of the current element.

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

XParent:   The parent of the current element.

Provides the parent of the current element.

The current element is specified via 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

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.

XPath Examples

Assuming the following XML response:

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

Or, alternatively, the following JSON response:

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

Here are some examples of valid XPaths:

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 is not an exhaustive list by any means, but should provide a general idea of the possibilities.

XSubTree:   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 via the XPath configuration setting. This configuration setting is read-only.

XText:   The text of the current element.

Provides the inner text of the current element.

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

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.

The appropriate 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.

KeepAliveRetryCount:   The number of keep-alive packets to be sent before the remotehost is considered disconnected.

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 number of times that the keep-alive packets will be sent before the remote host is considered disconnected. The system default if this value is not specified here is 9.

Note: This configuration setting is only available in the Unix platform. It is not supported in masOS or FreeBSD.

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

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

This 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; setting is useful when trying to connect to services that require a trusted port in 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 true, the socket will send all data that is ready to send at once. When false, the socket will send smaller buffered packets of data at small intervals. This is known as the Nagle algorithm.

By default, this config 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:

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 setting controls whether SSL packets should be logged. By default, this setting is False, as it is only useful 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 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 etc). OpenSSL recommends to use 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

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

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

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

sequences. Before, between, and after the certificates text is allowed which can be used e.g. for descriptions of the certificates. Please 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 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:

/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 certificate to use during SSL client authentication.

This setting specifies one or more CA certificates to be included in the request when performing SSL client authentication. Some servers require the entire chain, including CA certificates, to be presented when performing SSL client authentication. The value of this setting is a newline (CrLf) separated list of certificates. For instance:

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

SSLCipherStrength:   The minimum cipher strength used for bulk encryption.

This minimum cipher strength 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.

Please note that this 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 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 config setting.

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

The enabled 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: 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:

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.

Used to enable/disable the supported security protocols.

Not all supported protocols are enabled by default (the value of this setting is 4032). If you want more granular control over the enabled protocols, you can set this property to the binary 'OR' of one or more of the following values:

TLS1.312288 (Hex 3000)
TLS1.23072 (Hex C00) (Default)
TLS1.1768 (Hex 300) (Default)
TLS1 192 (Hex C0) (Default)
SSL3 48 (Hex 30) [Platform Only]
SSL2 12 (Hex 0C) [Platform Only]

SSLEnabledProtocols - 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 which 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 only supported 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 only available 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 the above 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 setting specifies whether the renegotiation_info SSL extension will be used in the request when using the internal security API. This setting is true by default, but can be set to false to disable the extension.

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

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

This 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 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 traffice for debugging purposes. When writing to this file the class will only append, it will not overwrite previous values.

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

SSLNegotiatedCipher:   Returns the negotiated cipher suite.

Returns the cipher suite negotiated during the SSL handshake.

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

SSLNegotiatedCipherStrength:   Returns the negotiated cipher suite strength.

Returns the strength of the cipher suite negotiated during the SSL handshake.

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

SSLNegotiatedCipherSuite:   Returns the negotiated cipher suite.

Returns the cipher suite negotiated during the SSL handshake represented as a single string.

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

SSLNegotiatedKeyExchange:   Returns the negotiated key exchange algorithm.

Returns the key exchange algorithm negotiated during the SSL handshake.

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

SSLNegotiatedKeyExchangeStrength:   Returns the negotiated key exchange algorithm strength.

Returns the strenghth of the key exchange algorithm negotiated during the SSL handshake.

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

SSLNegotiatedVersion:   Returns the negotiated protocol version.

Returns the protocol version negotiated during the SSL handshake.

Note: For server components (e.g. TCPServer) this is a per-connection 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 or-ed 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.
0x00000200Ignore unknown CTL signer revocation status.
0x00000400Ignore unknown Certificate Authority revocation status.
0x00000800Ignore unknown Root revocation status.
0x00008000Allow test Root certificate.
0x00004000Trust test Root certificate.
0x80000000Ignore non-matching CN (certificate CN not-matching server name).

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

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

This setting optionally specifies one or more CA certificates to be used when 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 setting should only be set 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 setting is a newline (CrLf) separated list of certificates. For instance:

-----BEGIN CERTIFICATE-----
MIIEKzCCAxOgAwIBAgIRANTET4LIkxdH6P+CFIiHvTowDQYJKoZIhvcNAQELBQAw
...
eWHV5OW1K53o/atv59sOiW5K3crjFhsBOd5Q+cJJnU+SWinPKtANXMht+EDvYY2w

d8q23djXZbVYiIfE9ebr4g3152BlVCHZ2GyPdjhIuLeH21VbT/dyEHHA
-----END CERTIFICATE-----

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

This 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 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 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.

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

TLS12SupportedGroups:   The supported groups for ECC.

This 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 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 round trip 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 setting.

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

In most cases this setting does not need to be modified. This should only be modified 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 setting holds a comma separated list of allowed signature algorithms. Possible values are:

  • "ed25519" (default)
  • "ed448" (default)
  • "ecdsa_secp256r1_sha256" (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 setting is only applicable when SSLEnabledProtocols includes TLS 1.3.
TLS13SupportedGroups:   The supported groups for (EC)DHE key exchange.

This setting specifies a comma separated list of named groups used in TLS 1.3 for key exchange. This setting should only be modified 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 which 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 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 TCP/IP stack. You can increase or decrease its size depending on the amount of data that you will be receiving. Increasing the value of the InBufferSize setting can provide significant improvements in performance in some cases.

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. Increasing the value of the OutBufferSize setting can provide significant improvements in performance in some cases.

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.
MaskSensitive:   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 FIPS, while all the 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 which 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 only applicable 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.

Trappable Errors (AzureFile Class)

Error Handling (C++)

Call the GetLastErrorCode() method to obtain the last called method's result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. Known error codes are listed below. If an error occurs, the GetLastError() method can be called to retrieve the associated error message.

Common Errors

600   A server error occurred, and/or the class was unable to process the server's response. Please refer to the error message for more information.
601   An unsupported operation or action was attempted.
602   The RawRequest or RawResponse configuration setting was queried without first setting the TransferredRequest configuration setting to ON.
603   The login credentials specified were invalid. Please refer to the error message for more information.
604   An invalid remote resource identifier (i.e., a name, path, Id, etc.) was specified.
