1)引入模块
var session = require(‘express-session‘); var cookieParser = require(‘cookie-parser‘);
2)应用cookie及session
app.use(cookieParser()); app.use(session({ resave: true, // don‘t save session if unmodified saveUninitialized: false, // don‘t create session until something stored secret: ‘love‘ }));
3)请求时,应用身份验证
app.use(function(req,res,next){ if (!req.session.user) { if(req.url=="/login"){ next();//如果请求的地址是登录则通过,进行下一个请求 } else { res.redirect(‘/login‘); } } else if (req.session.user) { next(); } });
4)登陆设计
app.get(‘/login‘,function(req,res){ res.render("login"); }); app.post(‘/login‘,function(req,res){ if(req.body.username=="love" && req.body.password=="love"){ var user = {‘username‘:‘love‘}; req.session.user = user; res.redirect(‘/admin/app/list‘); } else { res.redirect(‘/login‘); } }); app.get(‘/logout‘,function(req,res){ req.session.user = null; res.redirect(‘/login‘); });
