http调用速度慢

[m0_37360669]

string htp = "https://api.weixin.qq.com/cgi-bin/message/template/send?access_token=" + access_token;
jsonfh = HttpPost(htp, jsonText);

如果本地调用速度很快，但是放到服务器上，调用需要15秒才能返回结果

public static string HttpPost(string url, string postData)
{
ServicePointManager.ServerCertificateValidationCallback += RemoteCertificateValidate;
byte[] data = Encoding.UTF8.GetBytes(postData);
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
request.Proxy = null;
request.Method = "Post";
request.ContentType = "application/json";
request.ContentLength = data.Length;
request.KeepAlive = true;

Stream stream = request.GetRequestStream();
stream.Write(data, 0, data.Length);

HttpWebResponse response;
try
{
response = (HttpWebResponse)request.GetResponse();
}
catch (WebException ex)
{
response = (HttpWebResponse)ex.Response;
}

StreamReader reader = new StreamReader(response.GetResponseStream(), Encoding.UTF8);
string content = reader.ReadToEnd();

request.Abort();
response.Close();
reader.Dispose();
stream.Close();
stream.Dispose();

return content;
}

自己在服务器上ping这个地址的耗时吧

服务器进出带宽怎么样？应该考虑你的服务器与你本地环境的差异，主要是网络差异

这个问题，我专门花时间研究过，我是在远程服务器做了一个Rest Web API接口，发现调用时间有时候达到15秒左右，微软给出的答案是在http请示时，有一次代理检查，你的应该第二次请示就会很快了，还用，这种通讯不都是用现场的组件吗，我调用RestSharp，禁止代理后，速度明显变快，代码分离给你：

stopwatch.Start();
            string url = BaseUrl + @"/License/";

            var request = new RestRequest(url, Method.GET) { RequestFormat = DataFormat.Json };

            request.AddParameter("p_key", "OLMS_WXYT");
            client = new RestClient();

            IWebProxy webProXy = new WebProxy();
            webProXy.Credentials = null;
            client.Proxy = webProXy;
            IRestResponse response = client.Execute(request);

            if (!string.IsNullOrEmpty(response.Content))
            {
                string strJson = response.Content;
                GetNormalJson(ref strJson);

                var model = JsonConvert.DeserializeObject<LicenseModel>(strJson);

                AppendText(strJson);
                stopwatch.Stop();
