如何在发出事件Socket.io后侦听事件

npm install socket.io

const server = require('http').createServer();
const io = require('socket.io')(server);

io.on('connection', (socket) => {
  console.log('A client connected');

  // 监听自定义事件
  socket.on('customEvent', (data) => {
    console.log('Received custom event:', data);

    // 发送响应事件给客户端
    socket.emit('responseEvent', 'Response data');
  });
});

server.listen(3000, () => {
  console.log('Socket.io server listening on port 3000');
});

// 引入Socket.io客户端库
import io from 'socket.io-client';

// 连接到Socket.io服务器
const socket = io('http://localhost:3000');

// 发出自定义事件
socket.emit('customEvent', 'Event data');

// 监听响应事件
socket.on('responseEvent', (data) => {
  console.log('Received response event:', data);
});
