小乔流水人家 微信web协议分析和实现微信机器人（微信网页版 wx2.qq.com）

参考:https://www.jianshu.com/p/43f54e4b3dc1  http://www.07net01.com/2016/01/1201188.html  http://www.cnblogs.com/xiaozhi_5638/p/4923811.html https://segmentfault.com/a/1190000011996725?utm_source=tuicool&utm_medium=referral

 错误返回值分析：
{"Ret": 0,"ErrMsg": ""} 成功
{"Ret": -14,"ErrMsg": ""} ticket 错误
{"Ret": 1,"ErrMsg": ""} 传入参数 错误
{"Ret": 1100"ErrMsg": ""}未登录提示
{"Ret": 1101,"ErrMsg": ""}（可能：1未检测到登陆？）
{"Ret": 1102,"ErrMsg": ""}（可能：cookie值无效？）
（若返回为空，则说明协议头存在问题）

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。
