session:
安裝模組
cnpm install express-session
引入session註冊到路由
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) {
//設定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,連線一斷,session消失,因此在開發階段使用session請做好抓狂的準備。
cookie:
安裝模組
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) {
//設定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'});
});
