JavaWeb模拟微信（网页版）发送消息到好友。PS：不是公众号，是好友之间，或者发送到群。

1、发送文字消息到好友，或群。

1、登录微信网页版，使用firebug抓取发送文字的请求：https://wx2.qq.com/cgi-bin/mmwebwx-bin/webwxsendmsg

2、分析参数：

这里写图片描述
{\”BaseRequest\”:{\”Uin\”:123456,\”Sid\”:\”123456\”,\”Skey\”:\”@crypt_c799f4fc_7f98126a5836d9ed6fdbff40cd491c5f\”,\”DeviceID\”:\”e155964836553096\”},\”Msg\”:{\”Type\”:1,\”Content\”:\”hello\”,\”FromUserName\”:\”@abe6eb6ac61b71451c703f7126b8e454\”,\”ToUserName\”:\”abe6eb6ac61b71451c703f7126b8e454\”,\”LocalID\”:\”“+currentTimeMillis+”\”,\”ClientMsgId\”:\”“+currentTimeMillis+”\”}}
uin:表示微信帐号id，sid：每次会话生成新的，sky：每次会话生成新的，FromUserName：消息发送人，ToUserName：消息接收人，DeviceID：可重复

示例代码：
