## express 使用-1 1.全局路由攔截 2.app.use 3.Cookie的使用 4.Session的使用 ### 全局路由攔截 ~~~ app.all('/', (req,res) => { // 處理請求 }) ~~~ ### app.use 注冊中間函數 ~~~ app.use(express.static('public')); function middlewareA(req, res, next) { next(); } function middlewareB(req, res, next) { next(); } function middlewareC(req, res, next) { next(); } app.use(middlewareA); app.use(middlewareB); app.use(middlewareC); ~~~ ### Cookie的使用 ~~~ var cookieParser = require('cookie-parser'); app.use(cookieParser()); res.cookie("name",'zhangsan',{maxAge: 900000, httpOnly: true}); ~~~ ### Session的使用 ~~~ var session = require('express-session'); secret: '12345', name: 'testapp', //這里的name值得是cookie的name，默認cookie的name是：connect.sid cookie: {maxAge: 80000 } })); ~~~
