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
//这是一个短信平台的后台提交功能
string postData = string.Format("ECODE={0}&USERNAME={1}&PASSWORD={2}&MOBILE={3}&CONTENT={4}", ECODE, USERNAME, PASSWORD, MOBILE, CONTENT); // 要发放的数据
byte[] byteArray = System.Text.Encoding.UTF8.GetBytes(postData);
HttpWebRequest objWebRequest = (HttpWebRequest)WebRequest.Create("http://n.020sms.com/MSMSEND.ewing"); //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
