Question

使用github登录时，我一直得到user：null。

我不确定自己在做什么错，因为我可以看到用户登录

这周我一直在参考。我正在对数据库使用sequelize

Node + Express + Passport: req.user Undefined

还有这个

req.user undefined - node + express + passport-facebook

routes / users.js

router.get('/auth/github', passport.authenticate('github') );

router.get('/auth/github/callback', 
  passport.authenticate('github', { failureRedirect: '/'}),
  function(req, res, done) {
     console.log(`session ${req.session.passport.user} `); // renders the user id
      const user = req.session.passport.user;
        if(user){   
          const data = {
             id: req.session.passport.user

          };
          models.User.findOne({
            where: {
              id: data.id,
            },
          }).then((user) => {
            req.login(user, err => {
              return res.redirect('http://127.0.0.1:8001/dashboard');
            });

          });

        } else if(user == null) {
            console.log(info.message);
            res.status(403).send(info.message);
        }

  });
router.get("/current_user", (req, res) => {
  if(req.user){
    res.status(200).send({ user: req.user});
  } else {
    res.json({ user:null})
  }

});
