在微信后台，启用服务器配置。
服务器URL地址，要通过Token的验证。
private void Auth()
{
string token = ConfigurationManager.AppSettings["WeixinToken"];//从配置文件获取Token
if (string.IsNullOrEmpty(token))
{
LogTextHelper.Error(string.Format("WeixinToken 配置项没有配置！"));
} string echoString = HttpContext.Current.Request.QueryString["echoStr"];
string signature = HttpContext.Current.Request.QueryString["signature"];
string timestamp = HttpContext.Current.Request.QueryString["timestamp"];
string nonce = HttpContext.Current.Request.QueryString["nonce"]; if (CheckSignature(token, signature, timestamp, nonce))
{
if (!string.IsNullOrEmpty(echoString))
{
HttpContext.Current.Response.Write(echoString);
HttpContext.Current.Response.End();
}
}
}
关注订阅号，发一个文本消息。里面有用户的openid
/// <summary>
/// 主入口
/// </summary>
/// <param name="msg"></param>
private void OnRecvEvent(ReqMsgEventBase msg)
{
switch (msg.Event)
{
case Event.LOCATION:
break;
case Event.subscribe:
string content = “openid=”+msg.FromUserName;
SendResponseText(msg, content);
break;
case Event.unsubscribe:
break;
default:
break;
} }
