ASP.NET MVC 微信公共平台开发之获取用户消息并处理

ASP.NET MVC 微信公共平台开发

获取用户消息并处理

获取用户消息
用户发送的消息是在微信服务器发送的一个HTTP POST请求中包含的，获取用户发送的消息要从POST请求的数据流中获取

微信服务器推送消息到服务器的HTTP请求报文示例

POST /cgi-bin/wxpush? msg_signature=477715d11cdb4164915debcba66cb864d751f3e6×tamp=1409659813&nonce=1372623149 HTTP/1.1

Host: qy.weixin.qq.com

从POST请求中获取数据
