ASP.NET后台手动调用POST提交并获取返回值，用于短信平台接口

string userid = "lyancoffee";

            string password = "lyancofe";

            string phone = "15921263164";

            string content = "hello world";

            string time = DateTime.Now.ToString();

            string postData = string.Format("id={0}&pwd={1}&to={2}&content={3}&time={4}", userid, password, phone, content, time); // 要发放的数据

            byte[] byteArray = System.Text.Encoding.UTF8.GetBytes(postData);

            HttpWebRequest objWebRequest = (HttpWebRequest)WebRequest.Create("http://service.winic.org:8009/sys_port/gateway"); //发送地址

            objWebRequest.Method = "POST";//提交方式

            objWebRequest.ContentType = "application/x-www-form-urlencoded";

            objWebRequest.ContentLength = byteArray.Length;

            Stream newStream = objWebRequest.GetRequestStream(); // Send the data.

            newStream.Write(byteArray, 0, byteArray.Length); //写入参数

            newStream.Close();

            HttpWebResponse response = (HttpWebResponse)objWebRequest.GetResponse();//获取响应

            StreamReader sr = new StreamReader(response.GetResponseStream(), System.Text.Encoding.Default);

            string textResponse = sr.ReadToEnd() + "返回数据"; // 返回的数据


            Response.Write(textResponse);//打印返回值
