身份验证后护照不保存请求用户

时间:2019-05-04 01:05:39

标签: node.js express passport.js

当前用户可以使用github登录,我可以看到它在回调函数和通行证github文件中获取了req.user

  console.log(`frontid ${req.user.id}`) // logs user id

和护照

   console.log(`backbro ${id}`); // logs an id

但是,当我沿这条路线行驶时,github用户返回null,我不确定为什么。有几次,我看到已登录github的用户返回了current_user路由,但是我现在很少看到它。它有时显示,有时不显示。金达怪异。可能是会话问题吗?

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

是的,我查看了以下链接,但仍然没有合适的答案。

Node + Express + Passport: req.user Undefined

req.user undefined after twitter authentication using express sever, passport.js

访问此链接的方式是明确调用

  

localhost:8000 / api / users / auth / github

地址栏中的

路由/用户

router.get('/auth/github', passport.authenticate('github', {
  scope:[ 'profile', 'id']
}));
router.get('/auth/github/callback', 
  passport.authenticate('github', { session:true, failureRedirect: 'http:localhost:8001/signIn' }),
  function(req, res) {
    // Successful authentication, redirect home.
    // var token = jwt.sign({ id: req.user.id},  process.env.JWT_SECRET );
    // // res.cookie("jwt", token, { expires: new Date(Date.now() + 10*1000*60*60*24)});
    // jwt.verify(token, process.env.JWT_SECRET, function(err, data){
    //   console.log(err, data);
    // })
    const user = req.user
    req.logIn(user, err => {
      models.User.findOne({
         where: {
           id: req.user.id,
         },
       }).then(user => {
         const token = jwt.sign({ id: user.id  }, process.env.JWT_SECRET);
         // res.cookie("jwt", token, { expires: new Date(Date.now() + 10*1000*60*60*24)});
         jwt.verify(token, process.env.JWT_SECRET, function(err, data){
           console.log(err, data);
         })
         res.redirect('http://localhost:8001');

         // console.log(req.user)
       });
     });

    console.log(`frontid ${req.user.id}`)
    // res.redirect('')
    // console.log('this works', token);
