如何从java向socket io服务器发送消息

// Maven
<dependency>
    <groupId>io.socket</groupId>
    <artifactId>socket.io-client</artifactId>
    <version>1.0.0</version>
</dependency>

// Gradle
implementation 'io.socket:socket.io-client:1.0.0'

import io.socket.client.IO;
import io.socket.client.Socket;
import io.socket.emitter.Emitter;

public class SocketClient {
    private Socket socket;

    public SocketClient() {
        try {
            socket = IO.socket("http://your-socket-io-server.com:3000");
        } catch (URISyntaxException e) {
            e.printStackTrace();
        }
    }

    public void connect() {
        socket.connect();
    }

    public void disconnect() {
        socket.disconnect();
    }

    // 其他操作，如发送消息等
}

SocketClient client = new SocketClient();
client.connect();

socket.emit("message", "Hello Socket.IO");

socket.on("reply", new Emitter.Listener() {
    @Override
    public void call(Object... args) {
        String replyMessage = (String) args[0];
        System.out.println("Received reply from server: " + replyMessage);
    }
});

client.disconnect();
