            string result = "";
            HttpWebRequest req = (HttpWebRequest)WebRequest.Create(Url);
            req.Method = "POST";
            req.ContentLength = 0;//一定要添加这句
            HttpWebResponse resp = (HttpWebResponse)req.GetResponse();
            Stream stream = resp.GetResponseStream();
            //获取内容
            using (StreamReader reader = new StreamReader(stream, Encoding.UTF8))
            {
                result = reader.ReadToEnd();
