我知道很多人以前遇到过这个错误,但我找不到解决我的问题的方法。
我有一个想要规范化的 URL:
url = u"http://www.dgzfp.de/Dienste/Fachbeitr%C3%A4ge.aspx?EntryId=267&Page=5"
scheme, host_port, path, query, fragment = urlsplit(url)
path = urllib.unquote(path)
path = urllib.quote(path,safe="%/")
这给出了一条错误消息:
/usr/lib64/python2.6/urllib.py:1236: UnicodeWarning: Unicode equal comparison failed to convert both arguments to Unicode - interpreting them as being unequal
res = map(safe_map.__getitem__, s)
Traceback (most recent call last):
File "url_normalization.py", line 246, in <module>
logging.info(get_canonical_url(url))
File "url_normalization.py", line 102, in get_canonical_url
path = urllib.quote(path,safe="%/")
File "/usr/lib64/python2.6/urllib.py", line 1236, in quote
res = map(safe_map.__getitem__, s)
KeyError: u'\xc3'
我尝试从 URL 字符串中删除 unicode 指示符“u”,但没有收到错误消息。但是我如何自动删除 unicode,因为我直接从数据库读取它。
