Posted 2022-10-30

目前 官方小程序验证只有php的 ，暂未发现C#版本的  ，本人研究后贴出来大家分享下。

有不懂的请留言,本人会尽快回复的：

   废话不多说直接上代码:

    public class Msg : IHttpHandler
    
        //服务器日志类 
        Log log = new Log(AppDomain.CurrentDomain.BaseDirectory + @"/log/Log.txt");
        public void ProcessRequest(HttpContext context)
        
            string postString = string.Empty;
            if (HttpContext.Current.Request.HttpMethod.ToUpper() == "POST")
            
                using (Stream stream = HttpContext.Current.Request.InputStream)
                
                    Byte[] postBytes = new Byte[stream.Length];
                    stream.Read(postBytes, 0, (Int32)stream.Length);
                    postString = Encoding.UTF8.GetString(postBytes);
                

                if (!string.IsNullOrEmpty(postString))
                
                    log.log("=========================a.WeiXin 服务器验证========================= ");
                    log.log(postString);
                
                else
                
                    log.log("=========================b.WeiXin 服务器验证========================= ");
                    log.log(postString);
                
            
            else
            
                log.log("=========================c.WeiXin 服务器验证========================= ");
                Auth(context);
            

           
        

        private void Auth(HttpContext context)
        
            var signature = context.Request["signature"];
            var timestamp = context.Request["timestamp"];
            var nonce = context.Request["nonce"];
            var echostr = context.Request["echostr"];


            log.log("微信消息服务器验证传入数据" + string.Format("signature:0,timestamp:1,nonce:2,echostr:3", signature, timestamp, nonce, echostr));

            var token = "myxiaochengxu123";//自定义字段(自己填写3-32个字符)

            //timestamp和token和nonce 字典排序
            Dictionary<string, string> dic = new Dictionary<string, string>();
            dic.Add("token", token);
            dic.Add("nonce", nonce);
            dic.Add("timestamp", timestamp);
            var list = dic.OrderBy(s => s.Value);
            var conbineStr = "";
            foreach (var s in list)
            
                conbineStr = conbineStr + s.Value;
            
            string data = conbineStr;
            //sha1加密
            string secret = FormsAuthentication.HashPasswordForStoringInConfigFile(conbineStr, "SHA1").ToLower();
            var success = signature == secret;
            if (success)
            
                data = echostr;
            
            context.Response.ContentType = "text/plain";
            context.Response.Write(data);
        

        public bool IsReusable
        
            get
            
                return false;
            
        
    

配置成功即可： 这里注意 http服务的，再接收消息是也能够用https 到才行。
