keep reference to original requested url

[zabakala]

Following the example of this repo, what is the proper way of keeping a reference to the original requested url? This information is available in the former request as req.originalUrl but it gets lost if the user is not authenticated and the redirection (from GET /login to POST /login etc.) and authentication take place. The example in this repo has a static /

I tried to relay a state. Something like:

req.query.RelayState = req.params.redirect_to;
passport.authenticate('saml')(req, res, next);

... but to no avail. The information still gets lost.

Hi @davidgithub1980! Since the request data won't be available after redirect, have you considered storing them in a cookie or session storage?

@davidgithub1980 I had the same question here is what I did

const redirect_cookie = 'redirect-cookie';

app.use((req, res, next) => {
      if (!req.isAuthenticated()) {
        res.cookie(redirect_cookie, req.path);
        res.redirect('/login');
      } else {
        next();
      }
    });

 app.post('/login/callback', passport.authenticate('wsfed-saml2'), (req, res) => {
    if (req.cookies && req.cookies[redirect_cookie]) {
      res.clearCookie(redirect_cookie);
      res.redirect(req.cookies[redirect_cookie]);
    } else {
      res.redirect('/');
    }
  });
