如何使用Python从URL中删除查询字符串

Question

例:

http://example.com/?a=text&q2=text2&q3=text3&q2=text4

删除" q2 "后,它将返回:

http://example.com/?q=text&q3=text3

在这种情况下,有多个" q2 ",所有都被删除.

Answer 1

import sys

if sys.version_info.major == 3:
    from urllib.parse import urlencode, urlparse, urlunparse, parse_qs
else:
    from urllib import urlencode
    from urlparse import urlparse, urlunparse, parse_qs

url = 'http://example.com/?a=text&q2=text2&q3=text3&q2=text4&b#q2=keep_fragment'
u = urlparse(url)
query = parse_qs(u.query, keep_blank_values=True)
query.pop('q2', None)
u = u._replace(query=urlencode(query, True))
print(urlunparse(u))

Answer 2

import urlparse

url = 'http://example.com/?a=text&q2=text2&q3=text3&q2=text4'
urlparse.urljoin(url, urlparse.urlparse(url).path)

Answer 3

使用python的url操作库furl:

import furl
f = furl.furl("http://example.com/?a=text&q2=text2&q3=text3&q2=text4")
f.remove(['q2'])
print(f.url)

Answer 4

我下面的答案是最好的方法。

Answer 5

这不只是在字符上分割字符串的问题吗？

>>> url = http://example.com/?a=text&q2=text2&q3=text3&q2=text4
>>> url = url.split('?')[0]
'http://example.com/'
