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'});
});
