Question

I have the following code:

public function get_facebook()
    {
        $loginUrl = Helpers::fbLogin();

        if(Input::get('error'))
        {
            Session::flash('failure', 'You need to give permissions.');
            return Redirect::to('signup');
        }
        else
        {
            $facebook = IoC::resolve('facebook-sdk');
            $uid = $facebook->getUser();
            $fbuser = $facebook->api('/me', 'GET');

            $user = User::where('uid', '=', $uid)->or_where('email', '=', $fbuser['email'])->first();

            if(is_null($user)){
                Session::flash('fbuser', $fbuser);
                return Redirect::to('signup');
            } else {
                Auth::login($user);
                return Redirect::to('/');
            }
        }

        return Redirect::to($loginUrl);
    }

But I get this message:
An active access token must be used to query information about the current user.

Also when I print the $facebook->getAccessToken() & try opening my app with different facebook accounts I get same token.

What is access token & what do we use it for?

P.S. I have set up properly my appID & secret code. The problem is that sometimes it works, sometimes it doesn’t.

Answer 1

Access token is token, that is given to your application by user to access his/her information from your application. In order to get that token, user has to give you permission to access at least his basic information.
