微信token认证源码分享(c#版)

在开发时遇到一个问题:

  上线后提交申请微信提示"您的服务器没有正确响应token验证。。。",我查看日志发现根本就没有接收到来自微信的参数。

后来我又记录了微信请求方式和请求的字符串,想看看微信服务器到底有没有给我的服务器响应请求。结果是有的。并且通过了。

代码就添加了Request.HttpMethod和Request.QueryString没变,但不晓得怎么回事。

 /// <summary> 按照api说明对signature进行校验,校验成功返回参数echostr </summary>
        /// <returns></returns>
        public string CheckSign()
        {
            var httpMethod = Request.HttpMethod.ToLower();
            string httpString = string.Empty;
            if (httpMethod == "get")
            {
                httpString = Request.QueryString.ToString();
            }
            else if (httpMethod == "post")
            {
                httpMethod = Request.Form.ToString();
            }
            else
            {
                httpMethod = "请求方式不是get和post";
            }
            var strSignature = Request["signature"];
            var strEchostr = Request["echostr"];
            var strToken = "58jiancai";
            var strTimestamp = Request["timestamp"];
            var strNonce = Request["nonce"];

            log4net.LogManager.GetLogger("请求方式").Info(httpMethod);
            log4net.LogManager.GetLogger("请求字符串").Info(httpString);
            log4net.LogManager.GetLogger("pram1.strSignature").Info(strSignature);
            log4net.LogManager.GetLogger("pram2.strEchostr").Info(strEchostr);
            log4net.LogManager.GetLogger("pram3.strToken").Info(strToken);
            log4net.LogManager.GetLogger("pram4.strTimestamp").Info(strTimestamp);
            log4net.LogManager.GetLogger("pram5.strNonce").Info(strNonce);

            //step1:字典序排序
            string[] array = new[] { strToken, strTimestamp, strNonce };
            Array.Sort(array);
            log4net.LogManager.GetLogger("sort").Info(array[0] + "||" + array[1] + "||" + array[2]);

            //step2:sha1加密
            var strResult = FormsAuthentication.HashPasswordForStoringInConfigFile(string.Concat(array), "SHA1").ToLower();
            log4net.LogManager.GetLogger("sha1").Info(strResult);

            //step3:加密后的字符串与参数signature值比较
            if (strResult == strSignature.ToLower())
            {
                log4net.LogManager.GetLogger("result").Info("success");
                return strEchostr;
            }
            log4net.LogManager.GetLogger("result").Info("fail");
            return string.Empty;
        }
