这个例子只是简单实现了如何使用 Socket 类实现面向连接的通信。
注意:此例子的目的只是为了说明用套接字写程序的大概思路,而不是实际项目中的使用程序。在这个例子中,实际上还有很多问题没有解决,如消息边界问题、端口号是否被占用、消息命令的解析问题等。。
下面是两个程序的代码,(两个程序均为控制台程序)
先发服务端的(Server)完整代码如下:
引入命名空间:
using System.Net.Sockets; using System.Net; using System.Threading;
完整代码如下:
namespace SocketServer { 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; } } } } }
以上是服务端(server)的完整代码。
客户端(Client)的完整代码如下:
引入命名空间:
using System.Net; using System.Net.Sockets; using System.Threading;
完整代码:
namespace SocketClient { 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(); } } }
编译成功后,先运行 服务端(server),再运行客户端(client)即可达到通信效果。
效果如下图:
该程序已在局域网测试通过。(192.168.X.X)
php socket通信(tcp/udp)
注意
1.在socket_bind的时候ip地址不能真回环地址如127.0.0.1
2.server.php后台跑起来的时候 nohup php server.php > /var/tmp/a.log 2>&1 &
一: udp 方式
1) server.php
<?php //error_reporting( E_ALL ); set_time_limit( 0 ); ob_implicit_flush(); $socket = socket_create( AF_INET, SOCK_DGRAM, SOL_UDP ); if ( $socket === false ) { echo "socket_create() failed:reason:" . socket_strerror( socket_last_error() ) . "\n"; } $ok = socket_bind( $socket, '202.85.218.133', 11109 ); if ( $ok === false ) { echo "socket_bind() failed:reason:" . socket_strerror( socket_last_error( $socket ) ); } while ( true ) { $from = ""; $port = 0; socket_recvfrom( $socket, $buf,1024, 0, $from, $port ); echo $buf; usleep( 1000 ); } ?>
2) client.php
<?php $sock = socket_create(AF_INET, SOCK_DGRAM, SOL_UDP); $msg = 'hello'; $len = strlen($msg); socket_sendto($sock, $msg, $len, 0, '202.85.218.133', 11109); socket_close($sock); ?>
一: TCP 方式
1)server.php
<?php //error_reporting( E_ALL ); set_time_limit( 0 ); ob_implicit_flush(); $socket = socket_create( AF_INET, SOCK_STREAM, SOL_TCP ); socket_bind( $socket, '192.168.2.143', 11109 ); socket_listen($socket); $acpt=socket_accept($socket); echo "Acpt!\n"; while ( $acpt ) { $words=fgets(STDIN); socket_write($acpt,$words); $hear=socket_read($acpt,1024); echo $hear; if("bye\r\n"==$hear){ socket_shutdown($acpt); break; } usleep( 1000 ); } socket_close($socket) ?>
2) client.php
<?php $socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP); $con=socket_connect($socket,'192.168.2.143',11109); if(!$con){socket_close($socket);exit;} echo "Link\n"; while($con){ $hear=socket_read($socket,1024); echo $hear; $words=fgets(STDIN); socket_write($socket,$words); if($words=="bye\r\n"){break;} } socket_shutdown($socket); socket_close($sock); ?>
