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(); } }
