微信服务号校验URL核心代码

/验证URL        // @param sMsgSignature: 签名串，对应URL参数的msg_signature        // @param sTimeStamp: 时间戳，对应URL参数的timestamp        // @param sNonce: 随机串，对应URL参数的nonce        // @param sEchoStr: 随机串，对应URL参数的echostr        // @param sReplyEchoStr: 解密之后的echostr，当return返回0时有效        // @return：成功0，失败返回对应的错误码        public int VerifyURL(string sMsgSignature, string sTimeStamp, string sNonce, string sEchoStr, ref string sReplyEchoStr)        {            int ret = 0;            if (m_sEncodingAESKey.Length != 43)            {                return (int)WXBizMsgCryptErrorCode.WXBizMsgCrypt_IllegalAesKey;            }            ret = VerifySignature(m_sToken, sTimeStamp, sNonce, sEchoStr, sMsgSignature);            if (0 != ret)            {                return ret;            }            sReplyEchoStr = "";            string cpid = "";            try            {                sReplyEchoStr = Cryptography.AES_decrypt(sEchoStr, m_sEncodingAESKey, ref cpid); //m_sCorpID);            }            catch (Exception)            {                sReplyEchoStr = "";                return (int)WXBizMsgCryptErrorCode.WXBizMsgCrypt_DecryptAES_Error;            }            if (cpid != m_sCorpID)            {                sReplyEchoStr = "";                return (int)WXBizMsgCryptErrorCode.WXBizMsgCrypt_ValidateCorpid_Error;            }            return 0;        }以上是一段微信逛网提供的多年校验URL代码，单此代码我在微信企业号中使用过。目前由于公司需要做微信服务号使用时死活就报“签名错误-40001”.最后根据博客了解自己编写一个校验简单的方法。#region 自己额外添加        /// <summary>        /// MD5 加密        /// </summary>        /// <param name="s"></param>        /// <returns></returns>        public static string Sha1(string s)        {            using (var sha1 = SHA1.Create())            {                var result = sha1.ComputeHash(Encoding.UTF8.GetBytes(s));                var strResult = BitConverter.ToString(result);                return strResult.Replace("-", "").ToUpper();            }        }        /// <summary>        /// 验证微信签名        /// </summary>        /// <param name="token">token</param>        /// <param name="signature">签名</param>        /// <param name="timestamp">时间戳</param>        /// <param name="nonce">随机数</param>        /// <returns></returns>        public static bool WooCheckSignature(string token,             string signature, string timestamp, string nonce)        {            string[] ArrTmp = { token, timestamp, nonce };            //字典排序            Array.Sort(ArrTmp);            //拼接            string tmpStr = string.Join("", ArrTmp);            //sha1验证            tmpStr = Sha1(tmpStr); //FormsAuthentication.HashPasswordForStoringInConfigFile(tmpStr, "SHA1");                                   //tmpStr = Membership.CreateUser(tmpStr, "SHA1");            tmpStr = tmpStr.ToLower();            if (tmpStr == signature)            {                return true;            }            else            {                return false;            }        }        #endregion 自己额外添加用以上方法就方法就可以了。.net core 控制器使用/// <summary>        ///回调地址        /// </summary>        /// <returns></returns>        public IActionResult InitWxPort(string echoStr, string signature, string timestamp, string nonce)        {            var httpcontext = _accessor.HttpContext;            if (httpcontext.Request.Method.ToLower().Equals("get"))            {                string token = Constant.CorpToken;                //WeixinUtiliy weixin = new WeixinUtiliy();                if (WeixinUtiliy.WooCheckSignature(token, signature, timestamp, nonce))                {                    return Content(echoStr);                }                return Content("no as");                //return Content(weixin.Auth2(echoStr, signature, timestamp, nonce));            }            else            {                return Ok();            }                    }
