Symfony 2.8 -> 3.4 Upgrade IsGranted('IS_AUTHENTICATED_ANONYMOUSLY') Throws Errors

Question

I\'m in the process of upgrading Symfony from 2.8 to 3.4 and I have a Authentication Listener.

The constructor of the listener

  public function __co         


        

Answer 1

Issue was with the priority order.

thanks @cerad for giving a clue about it

bin/console debug:event-dispatcher kernel.request

helped to solve the issue. i was using

tags:
        - { name: kernel.event_listener, event: kernel.response, method: onKernelResponse, priority: 10 }

in Services.yml and it had a conflict with the

getSubscribedEvents()

therefore i have removed tags and only kept

public static function getSubscribedEvents()
    {
        return array(
            KernelEvents::REQUEST  => array('onKernelRequest', 10),
        );
    }

then i moved authentication listener to the down by giving high priority to other two listeners as same as it was there in symfony 2.8

Thanks all for helping me out on this specially @Pie @Cerad and @BoShurik

Inject AuthorizationChecker to your class

protected $authChecker;

public function __construct(AuthorizationChecker $authChecker)
    {
        $this->authChecker = $authChecker;
    }

By injecting it in your service.yml

XXXXXXXXX:
    class: App\XXX\XXXX\XXXXX
    arguments: [ "@security.authorization_checker" ]

And then use it to check role using isGranted

if ($this->authChecker->isGranted('IS_AUTHENTICATED_ANONYMOUSLY')) {

}

Answer 3

I believe it's the securitycontext which has been deprecated / removed. isGranted needs to be called on the authorization checker

return $this->get('security.authorization_checker');

You need the 'security.authorization_checker' service.

You then call isGranted on the authorization_checker service.

// get the service from the container or pass it in via injection
$authChecker = $this->get('security.authorization_checker');
if ($authChecker->isGranted('IS...')) { ... }

I used rector for easier migration. I would highly recommend https://github.com/rectorphp/rector for smooth migration. I can guarantee you will save lots of time by using this tool.
