GetFileInfo Method

Gets a file's information and metadata.

Syntax

backblazeb2.getFileInfo(fileId, [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){ }

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

'err' has 2 properties which hold detailed information:

err.code
err.message

Remarks

This method gets information and metadata for the file version specified by FileId (which must be a real file version, or a hide marker, not a multipart upload).

Calling this method will fire the FileList and MetadataList events, and will re-populate the File* and Metadata* properties.

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