import React, { useEffect } from 'react';
import io from 'socket.io-client';

const socket = io('http://your-server-url');

function App() {
  useEffect(() => {
    // 建立连接
    socket.connect();

    // 监听连接事件
    socket.on('connect', () => {
      console.log('Connected to server');
    });

    // 监听服务器发送的消息
    socket.on('message', (data) => {
      console.log('Received message:', data);
    });

    // 发送消息给服务器
    socket.emit('message', 'Hello server');
  }, []);
