我试图跟踪用户是否登录，如果没有，并尝试创建一个新的帖子，他将重定向到登录页面，然后我存储了他试图去的URL(新的帖子URL)，所以当他登录时，他会被重定向到那里，我使用Express会话来存储它，并让Passport本地做认证的事情，无论如何(新的帖子)URL在会话中，但当我登录(做帖子请求)时，它只是被删除了，尽管我尝试了其他帖子请求，看看是否这个问题，但它只在这个帖子上重置

检查并存储会话中url的中间件

module.exports.isLoggedIn = (req, res, next) => {
    if (!req.isAuthenticated()) {
        req.session.returnTo = req.originalUrl
        console.log(req.session.returnTo)
        req.flash('error', 'You must be signed in first!');
        return res.redirect('/login');
    }
    next();
}

module.exports.isNotLoggedIn = (req, res, next) => {
    if (req.isAuthenticated()) {
        return res.redirect('/campgrounds')
    }
    next();
}

登录路径

const express = require('express');
const router = express.Router();
const passport = require('passport');
const catchAsync = require('../utils/catchAsync');

router.get('/register', isNotLoggedIn, (req, res) => {
    res.render('users/register');
});

router.post('/register', isNotLoggedIn, catchAsync(async (req, res, next) => {
    try {
        const { email, username, password } = req.body;
        const user = new User({ email, username });
        const registeredUser = await User.register(user, password);
        req.login(registeredUser, err => {
            if (err) return next(err);
            req.flash('success', 'Welcome to Yelp Camp!');
            res.redirect('/campgrounds');
        })
    } catch (e) {
        req.flash('error', e.message);
        res.redirect('register');
    }
}));

router.get('/login', isNotLoggedIn, (req, res) => {
    console.log(req.session)
    res.render('users/login');
})

router.post('/login', isNotLoggedIn, passport.authenticate('local', { failureFlash: true, failureRedirect: '/login' }), (req, res) => {
    req.flash('success', 'welcome back!');
    const returnTo = req.session.returnTo || '/campgrounds';
    console.log('this thsisdifsdk')
    console.log(req.session) //todo this req.session is getting reset for some reason and i cannot return to what page i was goin for
    res.redirect(returnTo);
})

router.get('/logout', (req, res) => {
    req.logout((err) => {
        if (err) { return next(err); }
        req.flash('success', "Goodbye!");
        res.redirect('/campgrounds');

我试过的事情删除cookie，添加for cookie Secure：True，Change Secure：False，更改密钥，Make re Save True and False，make saveUnInitialized True and False，更改会话名称，都不起作用，我怀疑Passport是问题所在，但不知道如何解决
