Socket使用SOAP调用WCF

使用Socket调用WCF服务，就是要完全构造出服务调用的消息报文,服务使用的是BasicHttpBinding作为通信方式，那么就是http消息报文了，下面模拟消息报文

新建一个txt文本文档：request.txt，编写如下内容

POST /operation HTTP/1.1
Content-Type: text/xml; charset=utf-8
SOAPAction: "urlns://little.org/operation/Add"
Host: localhost:8082
Content-Length: 148
Expect: 100-continue
Accept-Encoding: gzip, deflate
Connection: Keep-Alive

<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/"><s:Body><Add xmlns="urlns://little.org"><a>3</a><b>5</b></Add></s:Body></s:Envelope>

然后就是将这段报文发送出去，http协议是应用层协议，是基于网络层的tcp协议的，所以使用socket实现

        public static void SocketConnect()
        {

            int port = 8081;
            string host = "127.0.0.1";
            IPAddress ip = IPAddress.Parse (host);
            IPEndPoint endpoint = new IPEndPoint (ip, port);
            Socket socket = new Socket (AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.IP);
            socket.Connect (endpoint);
            FileStream fs = new FileStream ("request.txt", FileMode.Open);
            StreamReader sr = new StreamReader (fs);
            string sendMsg = sr.ReadToEnd ();
            //string sendMsg = "Hello,Server";
            //System.ServiceModel.BasicHttpBinding
            byte[] sendBuf = Encoding.UTF8.GetBytes (sendMsg);
            socket.Send (sendBuf, sendBuf.Length, 0);
            byte[] buf = new byte[4096];
            socket.Receive (buf, buf.Length, 0);
            string msg = Encoding.UTF8.GetString (buf);
            Console.WriteLine ("接收到来自服务器的信息...");
            Console.WriteLine (msg);
            socket.Close ();
            //socket.Shutdown(SocketShutdown.Send)
        }

调用后返回结果报文：

HTTP/1.1 200 OK
Content-Length: 172
Content-Type: text/xml; charset=utf-8
Server: Microsoft-HTTPAPI/2.0
