Method Detail

tryParseCredentials

public static StorageCredentials tryParseCredentials(String connectionString)
                                              throws InvalidKeyException,
                                                     StorageException

Tries to determine the storage credentials from a connection string.

The format for the connection string is in the pattern "keyname=value". Multiple key/value pairs can be separated by a semi-colon, for example, "keyname1=value1;keyname2=value2". Either include an account name with an account key or a shared access signature. If you use an account name and account key, do not include a shared access signature, and vice versa.

The same connection string can be used as for CloudStorageAccount.parse(String) but here only the account name, account key, and sas key/value pairs will be examined.

Parameters:

connectionString - A String that contains the key/value pairs that represent the storage credentials.

Returns:

A StorageCredentials object representing the storage credentials determined from the connection string.

Throws:

InvalidKeyException - If the account key specified in connectionString is not valid.

StorageException

isHttpsOnly

public boolean isHttpsOnly()

Gets whether this StorageCredentials object only allows access via HTTPS.

Returns:

A boolean representing whether this StorageCredentials object only allows access via HTTPS.

getAccountName

public String getAccountName()

Returns the associated account name for the credentials. This is null for anonymous and shared access signature credentials.

Returns:

A String that represents the associated account name for the credentials

toString

public abstract String toString(boolean exportSecrets)

Returns a String that represents this instance.

Parameters:

exportSecrets - true to include sensitive data in the return string; otherwise, false.

Returns:

A String that represents this object, optionally including sensitive data.

transformUri

public URI transformUri(URI resourceUri)
                 throws URISyntaxException,
                        StorageException

Transforms a resource URI into a shared access signature URI, by appending a shared access token.

Parameters:

resourceUri - A java.net.URI object that represents the resource URI to be transformed.

Returns:

A java.net.URI object that represents the signature, including the resource URI and the shared access token.

Throws:

StorageException - If a storage service error occurred.

URISyntaxException - If the resource URI is not properly formatted.

transformUri

public StorageUri transformUri(StorageUri resourceUri)
                        throws URISyntaxException,
                               StorageException

Transforms a resource URI into a shared access signature URI, by appending a shared access token.

Parameters:

resourceUri - A StorageUri object that represents the resource URI to be transformed.

Returns:

A StorageUri object that represents the signature, including the resource URI and the shared access token.

Throws:

StorageException - If a storage service error occurred.

URISyntaxException - If the resource URI is not properly formatted.

transformUri

public abstract URI transformUri(URI resourceUri,
               OperationContext opContext)
                          throws URISyntaxException,
                                 StorageException

Transforms a resource URI into a shared access signature URI, by appending a shared access token and using the specified operation context.

Parameters:

resourceUri - A java.net.URI object that represents the resource URI to be transformed.

opContext - An OperationContext object that represents the context for the current operation. This object is used to track requests to the storage service, and to provide additional runtime information about the operation.

Returns:

A java.net.URI object that represents the signature, including the resource URI and the shared access token.

Throws:

StorageException - If a storage service error occurred.

URISyntaxException - If the resource URI is not properly formatted.

transformUri

public abstract StorageUri transformUri(StorageUri resourceUri,
                      OperationContext opContext)
                                 throws URISyntaxException,
                                        StorageException

Transforms a resource URI into a shared access signature URI, by appending a shared access token and using the specified operation context.

Parameters:

resourceUri - A StorageUri object that represents the resource URI to be transformed.

opContext - An OperationContext object that represents the context for the current operation. This object is used to track requests to the storage service, and to provide additional runtime information about the operation.
