#     qq登录
    path('loginQq/',qq.loginQq,name='loginQq/'),
    path('returns/',qq.returns,name='returns/'),

<a data-wow-delay=".5s" href="/blog/loginQq/"> »  QQ登录</a>

3, the application program created under the folder, and creates function.py utils for encapsulating function, a function for extracting the package OpenID (Tencent inside the database user id) from the return data

Function contents encapsulated as follows;

import re

def parse_jsonp(jsonp_str):
    try:
        return re.search('^[^(]*?\((.*)\)[^)]*$', jsonp_str).group(1)
    except:
        raise ValueError('无效数据！')
