req.session.returnTo 未定义

Question

我正在使用护照通过discord oauth2 对我的用户进行身份验证。我希望它们被重定向回原来的页面，而不是主页或仪表板。

我尝试将 URL 存储在会话中，如此处所述，但它不会保留到下一个请求。

我的页面需要身份验证的中间件：

module.exports = (req, res, next) => {
  if (req.user) {
    next();
  }
  else {
    req.session.returnTo = req.originalUrl;
    res.redirect('/auth');
  }
};

认证路线：

router.get("/auth", passport.authenticate("discord"));

router.get("/auth/redirect", passport.authenticate("discord", {
  failureRedirect: "/auth/forbidden"
}), (req, res) => {
  console.log(req.session); // doesnt have returnTo inside anymore ?
  res.redirect(req.session.returnTo || '/');
  delete req.session.returnTo;
});

console.log 显示用户已成功通过身份验证，但 returnTo 字段不再存在。

嗨，我遇到了同样的问题。尝试添加keepSessionInfo: true到passport.authenticate.

router.get("/auth", passport.authenticate("discord", {
    failureRedirect: "/auth/forbidden", keepSessionInfo: true
}), (req, res) => {
    console.log(req.session); // doesnt have returnTo inside anymore ?
    res.redirect(req.session.returnTo || '/');
    delete req.session.returnTo;
});
