Sending additional parameters to callback uri in socialite package for laravel

Question

Im trying to use Socialite package for laravel and I would like to know how to pass additional parameters to callback url. It seems that OAuth allows additional params, but

Answer 1

For some reason, Optional Parameters didn't work for me, so i ended up by using session to pass variables from redirect method to the callback method. it's not the best way to do it, but it does the trick.

Simplified example

use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
use App\User;
use Socialite;

class FacebookController extends Controller {

    /**
     * Create a new controller instance.
     *
     * @return void
     */
    public function redirect($my_variable)
    {
        session(['my_variable' => $my_variable]);

        return Socialite::driver('facebook')->redirect();
    }


    /**
     * Create a new controller instance.
     *
     * @return void
     */
    public function callback(Request $request)
    {
        try {

            $facebookAccount = Socialite::driver('facebook')->stateless()->user();

            $my_variable = session('my_variable');

            // your logic...

            return redirect()->route('route.name');


        } catch (Exception $e) {


            return redirect()->route('auth.facebook');
        }
    }
}
