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
地址栏中的localhost：8000 / api / users / auth / github
。
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: {

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