GetDownloadAuthToken Method

Create a download authorization token for one or more files in a bucket.

Syntax

backblazeb2.getDownloadAuthToken(allowedBucketId, allowedPrefix, validityDuration, [callback])

Callback

The 'callback' parameter specifies a function which will be called when the operation completes (or an error is encountered). If the 'callback' parameter is not specified, then the method will block and will not return until the operation completes (or an error is encountered).

The callback for this method is defined as:

function(err, data){ }

'err' is the error that occurred. If there was no error, then 'err' is 'null'.

'data' is the value returned by the method.

'err' has 2 properties which hold detailed information:

err.code
err.message

Remarks

This method creates and returns a download authorization token for the files in the bucket specified by AllowedBucketId whose names start with AllowedPrefix. The newly-created token will remain valid for the number of seconds specified by ValidityDuration, which must be a value in the range 1 to 604800 (1 week), inclusive.

Download authorization tokens created using this method can be used by anybody to download an applicable file by name; they cannot be used to download a file by Id. Refer to the DownloadFile method for more information.

The currently-authenticated application key must have the shareFiles capability to call this method successfully, otherwise the server will return an error. Refer to the AccountCapabilities property for more information.
