UnicodeWarning:Unicode 相等比较未能将两个参数都转换为 Unicode
UnicodeWarning: Unicode equal comparison failed to convert both arguments to Unicode
我知道很多人以前遇到过这个错误,但我找不到解决问题的办法。
我有一个 URL 想要标准化:
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="%/")
这会给出一条错误消息:
/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'
我试图从 URL 字符串中删除 unicode 指示符 "u",但我没有收到错误消息。但是我怎样才能自动摆脱 unicode 因为我直接从数据库中读取它。
urllib.quote()
没有正确解析 Unicode。要解决这个问题,您可以在读取 url 时调用 .encode()
方法(或从数据库中读取的变量)。所以 运行 url = url.encode('utf-8')
。有了这个你得到:
import urllib
import urlparse
from urlparse import urlsplit
url = u"http://www.dgzfp.de/Dienste/Fachbeitr%C3%A4ge.aspx?EntryId=267&Page=5"
url = url.encode('utf-8')
scheme, host_port, path, query, fragment = urlsplit(url)
path = urllib.unquote(path)
path = urllib.quote(path,safe="%/")
然后 path
变量的输出将是:
>>> path
'/Dienste/Fachbeitr%C3%A4ge.aspx'
这个有用吗?
