- sourceUri
- Uri
Specifies the Uri of the source blob. The value may be a URL of up to 2 KB in length that specifies a blob. The source blob must either be public or must be authenticated via a shared access signature. If the source blob is public, no authentication is required to perform the operation.
- base64BlockId
- String
A valid Base64 string value that identifies the block. Prior to
encoding, the string must be less than or equal to 64 bytes in
size. For a given blob, the length of the value specified for
the base64BlockId parameter must be the same
size for each block. Note that the Base64 string will be
URL-encoded.
- options
- StageBlockFromUriOptions
Optional parameters. StageBlockFromUriOptions.
- cancellationToken
- CancellationToken
Optional CancellationToken to propagate notifications that the operation should be cancelled.
Returns
A Response<T> describing the state of the updated block.
Remarks
A RequestFailedException will be thrown if a failure occurs.
