Can the callback for facebook-pasport be dynamically constructed?

Question

When using facebook-passport the usual thing to do is to specify the redirect_uri in the constructor of the FacebookStrategy thst you use, something like this:<

Answer 1

I was struggling to do this specifically with Angularjs, and wanted to redirect back to the same url that the login was initiated from.

My solution was to create a route in Angularjs that just implements a location back. I know this does not specifically answer the question, but I thought it would be helpful for anyone looking to do the same.

On the server:

app.get('/auth/facebook/', passport.authenticate ('facebook'));

app.get('/auth/facebook/callback', function (req, res, next) {
    var authenticator = passport.authenticate ('facebook', {
            successRedirect: '/fbcallback',
            failureRedirect: '/'
    });

    delete req.session.returnTo;
    authenticator (req, res, next);
})

Angular router:

when('/fbcallback', {
    template: "",
    controller: 'fbCtrl' 
}).

Angular controller:

app.controller("fbCtrl", function () {
    window.history.back();
});

You could probably do some other client side routing in the controller as well.
