HttpWebRequestとHttpWebResponseの例

HttpWebRequestの詳細な使用方法については、MSDNと私のもう1編という例を参照してください.この例は、クライアントが要求を開始しただけで、サービス側は対応する例を簡単に処理します.
クライアント要求

            string reqestMsg = "Tom";

            string responseMsg = string.Empty;

            byte[] buffer = Encoding.UTF8.GetBytes(reqestMsg);



            try

            {

　　　　　　//   http://www.cnblogs.com  　　

                HttpWebRequest request = (HttpWebRequest)WebRequest.Create("http://localhost:6603/WebServer.aspx");

                request.Method = "POST";

                request.ContentLength = buffer.Length;



                using (Stream requestStream = request.GetRequestStream())

                {

                    requestStream.Write(buffer, 0, buffer.Length);

                }



                HttpWebResponse resonse = (HttpWebResponse)request.GetResponse();

                Stream responseStream = resonse.GetResponseStream();

                

                using (StreamReader sr = new StreamReader(responseStream))

                {

                    responseMsg = sr.ReadToEnd();

                }



                resonse.Close();

            }

            catch (Exception ex)

            {

                responseMsg = ex.Message;

            }



            Response.Write(responseMsg);

サービス側対応

            string responseMsg = "NO MSG";



            if (Request.InputStream != null)

            {

                byte[] buffer = new byte[Request.InputStream.Length];

                Request.InputStream.Read(buffer, 0, buffer.Length);

                string msg = Encoding.UTF8.GetString(buffer);

                msg = msg.Replace("+", "%2B").Replace(" ", "%20");

                responseMsg = SayHello(msg);

            }



            Response.Write(responseMsg);
