將dbus.String轉換爲普通字符串

Question

我使用dbus從Songbird媒體播放器獲取當前播放的歌曲&元數據也來自dbus對象。

其中錯誤出現的行是： -

audio_file = MP3(current_playing_track['location'], ID3=ID3) 

的錯誤是： -

Traceback (most recent call last): 
    File "./last.py", line 42, in <module> 
    audio_file = MP3(current_playing_track['location'], ID3=ID3) 
    File "/usr/lib/python2.6/dist-packages/mutagen/__init__.py", line 73, in __init__ 
    self.load(filename, *args, **kwargs) 
    File "/usr/lib/python2.6/dist-packages/mutagen/id3.py", line 1949, in load 
    try: self.tags = ID3(filename, **kwargs) 
    File "/usr/lib/python2.6/dist-packages/mutagen/id3.py", line 74, in __init__ 
    super(ID3, self).__init__(*args, **kwargs)

    self.__fileobj = file(filename, 'rb') 
IOError: [Errno 2] No such file or directory: dbus.String(u'file:///media/Misc/Songbird%20Library/Puddle%20Of%20Mudd/Puddle%20Of%20Mudd%20-%20Unknown%20Album%20-%20Spin%20You%20Around.mp3', variant_level=1) 

如何文件位置轉換爲普通的字符串？

Answer 1

只是做str(your_dbus_string)
