Passport.js 重定向到 |successRedirect: '/profile'|但是 req.isAuthenticated() returns 错误

Question

以下代码是Node.js + Express + Passport.js开发的一个app的一部分。一个有效的用户被重定向到 /profile url（成功重定向），但是 req.isAuthenticated returns false 并且 req.user 是 undefined。我无法弄清楚可能是什么原因：

app.post('/login',
    passport.authenticate('local', {
        successRedirect: '/profile',// <-- a valid user gets redirected to `/profile`
        failureRedirect: '/',
        failureFlash: true
    })
);


app.get('/profile',function(req,res){    
    console.log('req.user: \n'+req.user)
    console.log('req.isAuthenticated(): '+req.isAuthenticated()) // <-- However, the `req.isAuthenticated()` returns false
    console.log('req.isAuthenticated: '+req.isAuthenticated)
    res.render('profile.ejs',{
        /*username: req.user.username*/ // <-- req.user is undefined
    });
})

Answer 1

在需要身份验证的每个路由上，您应该应用 passport.authenticate 中间件，即：

app.get('/profile', passport.authenticate('local'), (req, res) => {
  console.log(req.user);
  console.log(req.isAuthenticated());
}
