var express = require('express');var session = require('express-session');var app = express();app.use(session({    secret: '12345',    name: 'express_11_cookie',   //这里的name值得是cookie的name，默认cookie的name是：connect.sid    cookie: {maxAge: 80000 },     //设置maxAge是80000ms，即80s后session和相应的cookie失效过期}));app.get('/login', function(req, res){    if (req.session.sign) {//检查用户是否已经登录        console.log(req.session);//打印session的值        res.send('welecome <strong><a href="' + req.session.name + '"/></strong>, 欢迎你再次登录');    } else {        req.session.sign = true;        req.session.name = 'http://blog.csdn.net/wzjisking?viewmode=contents';        res.send('欢迎登陆！');    }});app.listen(8888);
