nodejs操作session和cookie

 

session：

安裝模塊

cnpm install express-session

 

引入session注冊到路由

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) { //設置session
    req.session.username = 'zhangsan'; //獲取session
 console.log(req.session); console.log(req.session.myname); res.render('/index', {title: '首頁'}); });

session存在於會話之中，連接一斷，session消失，因此在開發階段使用session請做好抓狂的准備。

 

 

cookie：

安裝模塊

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) { //設置cookie
    res.cookie('username','zhangsan'); res.cookie('username','zhangsan',{maxAge:10000}); //有效期以毫秒為單位

    //獲取cookie
 console.log(req.cookies); console.log(req.cookies.username); //刪除cookie
    res.clearCookie('username'); res.render('/index', {title: '首頁'}); });
