接收到微信用户发送过来的消息，我们服务器处理并回应。 需要注意一下，微信说明
我们无法保证我们服务器能在5秒回应的话，推荐使用异步处理，使用客服消息回复用户(不讨论客服消息次数限制等问题)

// 消息处理

}
Action里面处理
[HttpPost]
public ActionResult Access()
{
//异步操作 使用客服消息接口回复用户
Stream stream = Request.InputStream;
AsyncManager.OutstandingOperations.Increment();
var task = Task.Factory.StartNew(() => weixin.DisposeMsg(stream));
task.ContinueWith(t =>
{
//AsyncManager.Parameters["model"] = t.Result;
AsyncManager.OutstandingOperations.Decrement();
});
return Content("");
}
