微信web协议分析(微信网页版 wx2.qq.com)

1.打开首页,分配一个随机uuid,
2.根据该uuid获取二维码图片。
3.微信客户端扫描该图片,在客户端确认登录。
4.浏览器不停的调用一个接口,如果返回登录成功,则调用登录接口
5.此时可以获取联系人列表,可以发送消息。然后不断调用同步接口。
6.如果同步接口有返回,则可以获取新消息,然后继续调用同步接口。

urllogin.weixin.qq.com/cgi-bin/mmwebwx-bin/login
methodGET
paramstip : 1:未扫描 0:已扫描
uuid : 获取到的uuid
_ : 时间戳

返回数据(String):

window.code=xxx;xxx:    408 登陆超时    201 扫描成功    200 确认登录当返回200时,还会有window.redirect_uri="https://wx.qq.com/cgi-bin/mmwebwx-bin/webwxnewloginpage?ticket=xxx&uuid=xxx&lang=xxx&scan=xxx";

4. 登录获取Cookie(参考方法 login)
