在你的例子中，字符串被解码了两次，所以我们需要取消引号两次才能将其恢复

In [1]: import urllib
In [2]: urllib.unquote(urllib.unquote("what%2527s%2bthe%2btime%252c%2bnow%253f") )
Out[3]: "what's+the+time,+now?"

in your case, the string was decoded twice, so we need unquote twice to get it back

In [1]: import urllib
In [2]: urllib.unquote(urllib.unquote("what%2527s%2bthe%2btime%252c%2bnow%253f") )
Out[3]: "what's+the+time,+now?"

像这样的东西吗？

title = u"what%2527s%2bthe%2btime%252c%2bnow%253f"
print title.encode('ascii','ignore')

另外，看看这个

Something like this?

title = u"what%2527s%2bthe%2btime%252c%2bnow%253f"
print title.encode('ascii','ignore')

Also, take a look at this

您可以使用以下内容转换 %(hex) 转义字符：

import re

def my_decode(s):
    re.sub('%([0-9a-fA-F]{2,4})', lambda x: unichr(int(x.group(1), 16)), s)

s = u'what%2527s%2bthe%2btime%252c%2bnow%253f'
print my_decode(s)

results in the unicode string

u'what\u2527s+the+time\u252c+now\u253f'

不确定您如何知道将 \u2527 转换为单引号，或在转换为 ascii 时删除 \u253f 和 \u252c 字符

You could convert the %(hex) escaped chars with something like this:

import re

def my_decode(s):
    re.sub('%([0-9a-fA-F]{2,4})', lambda x: unichr(int(x.group(1), 16)), s)

s = u'what%2527s%2bthe%2btime%252c%2bnow%253f'
print my_decode(s)

results in the unicode string
