合并socket.io和express.js会话

npm install express socket.io express-session

const express = require('express');
const app = express();
const session = require('express-session');

app.use(session({
    secret: 'my-secret',
    resave: true,
    saveUninitialized: true
}));

const server = app.listen(3000, function() {
    console.log('Server listening on port 3000');
});

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

io.use((socket, next) => {
    sessionMiddleware(socket.request, socket.request.res, next);
});

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

    // Access session data
    console.log(socket.request.session.user);

    socket.on('disconnect', () => {
        console.log('Client disconnected');
    });
});
