验证签名,接入微信公众平台：不能直接返回String,直接返回String微信服务器不接受。

// GET: api/checkSignature/5
        public HttpResponseMessage Get(string signature , string timestamp , string nonce , string echostr)
        {

            string TOKEN = "微信公众平台设置的TOKEN";

            var response = new HttpResponseMessage(HttpStatusCode.OK);
            string[] ArrTmp = { TOKEN, timestamp, nonce };
            string result = "";
            Array.Sort(ArrTmp);
            string tmpStr = string.Join("", ArrTmp);
            string sign = SignHelper.Sha1Sign(tmpStr);
            Log.WorkInfo("sign:" + sign);
            Log.WorkInfo("signature:" + signature);
            if (sign.Equals(signature))
            {
                result =  echostr;
            }
            else
            {
                result =  "signature fail";
            }
            response.Content = new StringContent(result, System.Text.Encoding.UTF8, "text/plain");
            return response;
