我正在使用 dbus 从 Songbird Media Player 获取当前正在播放的歌曲，元数据也来自 dbus 对象。
出错的那一行是:-
audio_file = MP3(current_playing_track['location'], ID3=ID3)
错误是:-
Traceback (most recent call last):
File "./last.py", line 42, in <module>
audio_file = MP3(current_playing_track['location'], ID3=ID3)

如何将文件位置转换为普通字符串？
请您参考如下方法:
只需执行 str( your_dbus_string )
