我有这个:
a = {'album': u'Metamorphine', 'group': 'monoku', 'name': u'Son Of Venus (Danny\xb4s Song)', 'artist': u'Leandra', 'checksum': '2836e33d42baf947e8c8adef48921f2f76fcb37eea9c50b0b59d7651', 'track_number': 8, 'year': '2008', 'genre': 'Darkwave', 'path': u'/media/data/musik/Leandra/2008. Metamorphine/08. Son Of Venus (Danny\xb4s Song).mp3', 'user_email': '[email protected]', 'size': 6624104}
data = urllib.urlencode(mp3_data)
这就引发了一个异常(exception):
Traceback (most recent call last):
File "playkud.py", line 44, in <module>

v = quote_plus(str(v))
UnicodeEncodeError: 'ascii' codec can't encode character u'\xb4' in position 19: ordinal not in range(128)
和ipython(2.5):
In [7]: urllib.urlencode(a)
UnicodeEncodeError Traceback (most recent call last)
/home/diegueus9/<ipython console> in <module>()
/usr/lib/python2.5/urllib.pyc in urlencode(query, doseq)
1248 for k, v in query:
1249 k = quote_plus(str(k))
-> 1250 v = quote_plus(str(v))
1251 l.append(k + '=' + v)
1252 else:
UnicodeEncodeError: 'ascii' codec can't encode character u'\xb4' in position 19: ordinal not in range(128)
我该如何解决?
最佳答案
urlencode
库期望使用str
格式的数据,并且由于无法提供指定编码的方式,因此无法很好地处理Unicode数据。尝试以下方法:
mp3_data = {'album': u'Metamorphine',
'group': 'monoku',
'name': u'Son Of Venus (Danny\xb4s Song)',
'artist': u'Leandra',
'checksum': '2836e33d42baf947e8c8adef48921f2f76fcb37eea9c50b0b59d7651',
'track_number': 8,
'year': '2008', 'genre': 'Darkwave',
'path': u'/media/data/musik/Leandra/2008. Metamorphine/08. Son Of Venus (Danny\xb4s Song).mp3',
'user_email': '[email protected]',
'size': 6624104}
str_mp3_data = {}
for k, v in mp3_data.iteritems():
str_mp3_data[k] = unicode(v).encode('utf-8')
data = urllib.urlencode(str_mp3_data)
我所做的是确保在将字典传递到
str
函数之前,使用UTF-8将所有数据编码为urlencode
。
