供以后参考(例如:For python3)

>>> import urllib.request as req
>>> query = 'eventName=theEvent&eventDescription=testDesc'
>>> req.pathname2url(query)
>>> 'eventName%3DtheEvent%26eventDescription%3DtestDesc'

Python 3:

urllib parse。引用+(字符串，安全= "，编码= no, errors= no)

如果urllib.parse. parse。urlencode()给你错误，然后尝试urllib3模块。

语法如下:

import urllib3
urllib3.request.urlencode({"user" : "john" }) 

import urllib.parse
query = 'Hellö Wörld@Python'
urllib.parse.quote(query) // returns Hell%C3%B6%20W%C3%B6rld%40Python

Python 2

你要找的是urllib.quote_plus:

safe_string = urllib.quote_plus('string_of_characters_like_these:$#@=?%^Q^$')

#Value: 'string_of_characters_like_these%3A%24%23%40%3D%3F%25%5EQ%5E%24'

Python 3

在Python 3中，urllib包被分解成更小的组件。您将使用urllib.parse。Quote_plus(注意解析子模块)

import urllib.parse
safe_string = urllib.parse.quote_plus(...)

如果你不想使用urllib。
