C# 开发微信小程序 系列（1） 接入服务器 验证token

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。
