Node + Express 会话过期

Node + Express 会话过期？

javascript
const express = require('express');
const session = require('express-session');
const app = express();
// 设置会话过期时间为30分钟
app.use(session({
  secret: 'mysecret',
  resave: false,
  saveUninitialized: true,
  cookie: { maxAge: 30 * 60 * 1000 }
}));
// 检查会话过期
app.use((req, res, next) => {
  if (req.session && req.session.user) {
    const currentTime = new Date().getTime();
    const lastActivityTime = req.session.lastActivityTime || currentTime;
    // 如果距离上次活动时间超过30分钟，则会话过期
    if (currentTime - lastActivityTime > 30 * 60 * 1000) {
      req.session.destroy();
      res.redirect('/login');
    } else {
      req.session.lastActivityTime = currentTime;
      next();
    }
  } else {
    next();
  }
});
// 路由和其他中间件
// ...
// 启动服务器
app.listen(3000, () => {
  console.log('Server is running on port 3000');
});
