客户端Socket.io覆盖或hendle断开连接事件

const io = require('socket.io-client');
const socket = io('http://localhost:3000');

socket.on('connect', () => {
    console.log('Connected to server');
});

socket.on('disconnect', (reason) => {
    console.log(`Disconnected from server due to ${reason}`);
    // 可以在这里添加重连逻辑或其他恢复措施
});

socket.on('reconnect', (attemptNumber) => {
    console.log(`Reconnected after ${attemptNumber} attempts`);
});

const express = require('express');
const http = require('http');
const socketIo = require('socket.io');

const app = express();
const server = http.createServer(app);
const io = socketIo(server);

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

    socket.on('disconnect', (reason) => {
        console.log(`User disconnected due to ${reason}`);
        // 可以在这里处理用户断开连接后的逻辑
    });
});

server.listen(3000, () => {
    console.log('Server is running on port 3000');
});
