socket 服务器浏览器与服务器客户端实例

一、服务器与浏览器

// 取得本机的loopback网络地址，即127.0.0.1
            IPAddress address = IPAddress.Loopback;
            IPEndPoint endPoint = new IPEndPoint(address, 49152);
            Socket socket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
            socket.Bind(endPoint);
            socket.Listen(10);
            Console.WriteLine("开始监听，端口号;{0}.", endPoint.Port);
            while (true)
            {
                Socket client = socket.Accept();
                Console.WriteLine(client.RemoteEndPoint);
                byte[] buffer = new byte[4096];
                int length = client.Receive(buffer, 4096, SocketFlags.None);
                System.Text.Encoding utf8 = System.Text.Encoding.UTF8;
                string requestString = utf8.GetString(buffer, 0, length);
                Console.WriteLine(requestString);
                string statusLine = "HTTP/1.1 200 OK\r\n";
                byte[] statusLineBytes = utf8.GetBytes(statusLine);
                string responseBody = "<html><head><title>From Socket Server</title></head><body><hl>Hello,world.</hl></body></html>";
                byte[] responseBodyBytes = utf8.GetBytes(responseBody);
                // 回应的头部
                string responseHeader = string.Format("Content-Type:text/html;charset=UTF-8\r\nContent-Length:{0}\r\n",
                    responseBody.Length);
                byte[] responseHeaderBytes = utf8.GetBytes(responseHeader);
                // 向客户端发送状态消息
                client.Send(statusLineBytes);
                // 向客户端发送回应头
                client.Send(responseHeaderBytes);
                client.Send(new byte[] { 13, 10 });
                client.Send(responseBodyBytes);
                client.Close();
                if (Console.KeyAvailable)
                {
                    break;
                }
                socket.Close();
            }

最后在浏览器地址栏中输入：http://localhost:49152

二、服务器客户端

服务端：

class Program
    {
        private static byte[] result = new byte[1024];
        private static int myProt = 8885;   //端口
        static Socket serverSocket;
        static void Main(string[] args)
        {
            //服务器IP地址
            IPAddress ip = IPAddress.Parse("127.0.0.1");
            serverSocket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
            serverSocket.Bind(new IPEndPoint(ip, myProt));  //绑定IP地址：端口
            serverSocket.Listen(10);    //设定最多10个排队连接请求
            Console.WriteLine("启动监听{0}成功", serverSocket.LocalEndPoint.ToString());
            //通过Clientsoket发送数据
            Thread myThread = new Thread(ListenClientConnect);
            myThread.Start();
            Console.ReadLine();
        }

        /// <summary>
        /// 监听客户端连接
        /// </summary>
        private static void ListenClientConnect()
        {
            while (true)
            {
                Socket clientSocket = serverSocket.Accept();
                clientSocket.Send(Encoding.ASCII.GetBytes("Server Say Hello"));
                Thread receiveThread = new Thread(ReceiveMessage);
                receiveThread.Start(clientSocket);
            }
        }

        /// <summary>
        /// 接收消息
        /// </summary>
        /// <param name="clientSocket"></param>
        private static void ReceiveMessage(object clientSocket)
        {
            Socket myClientSocket = (Socket)clientSocket;
            while (true)
            {
                try
                {
                    //通过clientSocket接收数据
                    int receiveNumber = myClientSocket.Receive(result);
                    Console.WriteLine("接收客户端{0}消息{1}", myClientSocket.RemoteEndPoint.ToString(), Encoding.ASCII.GetString(result, 0, receiveNumber));
                }
                catch(Exception ex)
                {
                    Console.WriteLine(ex.Message);
                    myClientSocket.Shutdown(SocketShutdown.Both);
                    myClientSocket.Close();
                    break;
                }
            }
        }
    }

客户端：

class Program
    {
        private static byte[] result = new byte[1024];
        static void Main(string[] args)
        {
            //设定服务器IP地址
            IPAddress ip = IPAddress.Parse("127.0.0.1");
            Socket clientSocket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
            try
            {
                clientSocket.Connect(new IPEndPoint(ip, 8885)); //配置服务器IP与端口
                Console.WriteLine("连接服务器成功");
            }
            catch
            {
                Console.WriteLine("连接服务器失败，请按回车键退出！");
                return;
            }
            //通过clientSocket接收数据
            int receiveLength = clientSocket.Receive(result);
            Console.WriteLine("接收服务器消息：{0}",Encoding.ASCII.GetString(result,0,receiveLength));
            //通过 clientSocket 发送数据
            for (int i = 0; i < 10; i++)
            {
                try
                {
                    Thread.Sleep(1000);    //等待1秒钟
                    string sendMessage = "client send Message Hellp" + DateTime.Now;
                    clientSocket.Send(Encoding.ASCII.GetBytes(sendMessage));
                    Console.WriteLine("向服务器发送消息：{0}" + sendMessage);
                }
                catch
                {
                    clientSocket.Shutdown(SocketShutdown.Both);
                    clientSocket.Close();
                    break;
                }
            }
            Console.WriteLine("发送完毕，按回车键退出");
            Console.ReadLine();
        }
    }
