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‘});});nodejs操作session和cookie
