 private static string Post(string url, string postData, int retryCount = 3)
        {
            do
            {

                    HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
                    request.Method = "post";
                    request.ContentType = "application/json;charset=utf-8";
                    byte[] buffer = encoding.GetBytes(postData);
                    request.ContentLength = buffer.Length;
                    request.GetRequestStream().Write(buffer, 0, buffer.Length);
                    HttpWebResponse response = (HttpWebResponse)request.GetResponse();
                    var rspStm = response.GetResponseStream();
