nodejs操作session和cookie

 

session：

安装模块

cnpm install express-session

 

引入session注册到路由

var express = require('express'); var session = require('express-session'); var router = express.Router(); router.use(session({secret: 'keyboard cat', resave: false, saveUninitialized: true, cookie: {maxAge: 60000}}));

 

操作session

router.get('/', function (req, res, next) { //设置session
    req.session.username = 'zhangsan'; //获取session
 console.log(req.session); console.log(req.session.myname); res.render('/index', {title: '首页'}); });

session存在于会话之中，连接一断，session消失，因此在开发阶段使用session请做好抓狂的准备。

 

 

cookie：

安装模块

cnpm install cookie-parser

 

引入cookie

var express = require('express'); var cookie = require('cookie-parser'); var router = express.Router();

 

操作cookie

router.get('/', function (req, res, next) { //设置cookie
    res.cookie('username','zhangsan'); res.cookie('username','zhangsan',{maxAge:10000}); //有效期以毫秒为单位

    //获取cookie
 console.log(req.cookies); console.log(req.cookies.username); //删除cookie
    res.clearCookie('username'); res.render('/index', {title: '首页'}); });
