FilePath (string): The full path of the torrent file.
The FilePath parameter name is only available from v3.2 onwards.
In v3.1 and earlier FileName must be used instead. While the earlier name will still work, we recommend that, from v3.2 onwards, FilePath is used instead.
AnnounceUri (string): An announce URI contained in the torrent file.
Get on or more announce URI of a torrent called myTorrent.torrent.
