基于Flask的web微信

Request URL: https://login.wx.qq.com/jslogin?appid=wx782c26e4c19acffb&
redirect_uri=https%3A%2F%2Fwx.qq.com%2Fcgi-bin%2Fmmwebwx-bin%2Fwebwxnewloginpage&fun=new&lang=zh_CN&_=1552006589440

 微信的登录请求URl

取到后十三位数字，进行拼接，然后发起请求。

    ctime = time.time()
    t = int(ctime*1000)

 

请求结果中得到uuid，

Request URL: https://login.weixin.qq.com/qrcode/QbTJp0CvmA==

 拼接uuid，向后台发送请求。拿到url，向html展示。

Request URL:

https://login.wx.qq.com/cgi-bin/mmwebwx-bin/login?loginicon=true&uuid=4YSNlh_5MA==&tip=1&r=-1524271316&_=1552007464727

向后台不断发起请求，检测是否有扫码

 

没有扫码，code408，扫了未确认，code201，扫了确认，code200.

扫码之后，拿到头像，avator = re.findall("window.userAvatar = '(.*?)'",r1.text)，确认之后，拿到重定向url

拿到重定向url进行拼接后，拿到返回值。

 

拿到返回值的内容，拼接pass_ticket向后台发送数据，拿返回值
