如何向Socket.io服务器发送带有WebSocket的消息

npm install socket.io

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

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

  // 监听客户端发送的消息
  socket.on('message', (data) => {
    console.log('Received message:', data);

    // 向客户端发送消息
    socket.emit('response', 'Message received');
  });

  // 监听客户端断开连接事件
  socket.on('disconnect', () => {
    console.log('A client disconnected');
  });
});

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

// 引入Socket.IO库
import io from 'socket.io-client';

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

// 发送消息
socket.emit('message', 'Hello Server');

// 监听服务器的响应
socket.on('response', (data) => {
  console.log('Server response:', data);
});
