1、PHP与WebSocket
在PHP中,可以使用Ratchet库来实现WebSocket客户端和服务器的功能,以下是一个简单的PHP WebSocket服务器示例:
<?php require 'vendor/autoload.php'; use Ratchet\Server\IoServer; use Ratchet\Http\HttpServer; use Ratchet\WebSocket\WsServer; use MyAppChat; $server = IoServer::factory( new HttpServer( new WsServer( new Chat() ) ), 8080 ); $server->run(); ?>
在这个示例中,我们首先引入了Ratchet库,然后创建了一个基于HttpServer和WsServer的IoServer实例,接着启动了这个服务器并监听8080端口,Chat类需要继承WsServer,并实现相应的方法来处理WebSocket事件。
2、Java与WebSocket
在Java中,可以使用Java-WebSocket库来实现WebSocket客户端和服务器的功能,以下是一个简单的Java WebSocket服务器示例:
import org.java_websocket.server.WebSocketServer; import org.java_websocket.handshake.ClientHandshake; import org.java_websocket.WebSocket; import org.java_websocket.framing.TextMessage; import java.net.InetSocketAddress; import java.io.IOException; import java.util.concurrent.CopyOnWriteArraySet; public class SimpleWebSocketServer extends WebSocketServer { private static final int PORT = 8080; private static CopyOnWriteArraySet<SimpleWebSocketServer> webSocketSet = new CopyOnWriteArraySet<>(); private static Thread messageThread; //消息处理线程 private volatile boolean isRunning = true; //运行标志位 public SimpleWebSocketServer(InetSocketAddress address) { super(address); } @Override public void onOpen(WebSocket conn, ClientHandshake handshake) { System.out.println("新连接加入:" + conn.getRemoteSocketAddress().getAddress().getHostAddress()); //打印IP地址信息 webSocketSet.add(this); //添加到集合中方便移除连接时判断是否还有其他连接存在此服务器上,如果不存在则关闭服务器,防止内存泄漏问题!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!&&&&&&&&&&&&&&&&>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>------------------------------------------------------------------------------------------------------------------------------------------------------------>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>8763456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789
