如何制作spring websocket + node.js客户端

npm init -y

npm install websocket

const WebSocket = require('websocket').client;

const client = new WebSocket();

client.on('connectFailed', (error) => {
    console.log('连接失败: ' + error.toString());
});

client.on('connect', (connection) => {
    console.log('连接成功');

    connection.on('error', (error) => {
        console.log('连接错误: ' + error.toString());
    });

    connection.on('close', () => {
        console.log('连接关闭');
    });

    connection.on('message', (message) => {
        if (message.type === 'utf8') {
            console.log('收到消息: ' + message.utf8Data);
        }
    });
});

client.connect('ws://localhost:8080/websocket');

node client.js

import org.springframework.web.socket.TextMessage;
import org.springframework.web.socket.WebSocketSession;
import org.springframework.web.socket.handler.TextWebSocketHandler;

public class WebSocketHandler extends TextWebSocketHandler {
    @Override
    protected void handleTextMessage(WebSocketSession session, TextMessage message) throws Exception {
        String payload = message.getPayload();
        System.out.println("收到消息: " + payload);

        // 处理接收到的消息

        session.sendMessage(new TextMessage("回复消息"));
    }
}

import org.springframework.context.annotation.Configuration;
import org.springframework.web.socket.config.annotation.EnableWebSocket;
import org.springframework.web.socket.config.annotation.WebSocketConfigurer;
import org.springframework.web.socket.config.annotation.WebSocketHandlerRegistry;

@Configuration
@EnableWebSocket
public class WebSocketConfig implements WebSocketConfigurer {
    @Override
    public void registerWebSocketHandlers(WebSocketHandlerRegistry registry) {
        registry.addHandler(new WebSocketHandler(), "/websocket").setAllowedOrigins("*");
    }
}
