Symnedi/Security

Install

composer require symnedi/security

Register the extension:

# app/config/config.neon
extensions:
	- Symnedi\Security\DI\SecurityExtension
	- Symnedi\EventDispatcher\DI\EventDispatcherExtension

Usage

Voters

First, read Symfony cookbook

Then create new voter implementing Symfony\Component\Security\Core\Authorization\Voter\VoterInterface and register it as service in config.neon:

services:
	- App\SomeModule\Security\Voter\MyVoter

Then in place, where we need to validate access, we'll just use AuthorizationChecker:

use Symfony\Component\Security\Core\Authorization\AuthorizationCheckerInterface;


class Presenter
{

	/**
	 * @var AuthorizationCheckerInterface
	 */
	private $authorizationChecker;

	
	public function __construct(AuthorizationCheckerInterface $authorizationChecker)
	{
		$this->authorizationChecker = $authorizationChecker;
	}


	/**
	 * @param PresenterComponentReflection $element
	 */
	public function checkRequirements($element)
	{
		if ($this->authorizationChecker->isGranted('access', $element) === FALSE) {
			throw new ForbiddenRequestException;
		}
	}

}

Firewalls

Original Symfony firewalls pretty simplified and with modular support by default.

All we need to create is a matcher and a listener.

Request Matcher

This service will match all sites in admin module - urls starting with /admin:

use Symfony\Component\HttpFoundation\Request;
use Symnedi\Security\Contract\HttpFoundation\RequestMatcherInterface;


class AdminRequestMatcher implements RequestMatcherInterface
{

	/**
	 * {@inheritdoc}
	 */
	public function getFirewallName()
	{
		return 'adminSecurity';
	}
	
	
	/**
	 * {@inheritdoc}
	 */
	public function matches(Request $request)
	{
		$url = $request->getPathInfo();
		return strpos($url, '/admin') === 0;
	}

}

Firewall Listener

It will ensure that user is logged in and has 'admin' role, otherwise redirect.

use Nette\Application\AbortException;
use Nette\Application\Application;
use Nette\Application\Request;
use Nette\Security\User;
use Symnedi\Security\Contract\Http\FirewallListenerInterface;


class LoggedAdminFirewallListener implements FirewallListenerInterface
{

	/**
	 * @var User
	 */
	private $user;
	

	public function __construct(User $user)
	{
		$this->user = $user;
	}
	
	
	/**
	 * {@inheritdoc}
	 */
	public function getFirewallName()
	{
		return 'adminSecurity';
	}

	
	/**
	 * {@inheritdoc}
	 */
	public function handle(Application $application, Request $applicationRequest)
	{
		if ( ! $this->user->isLoggedIn()) {
			throw new AbortException;
		}

		if ( ! $this->user->isInRole('admin')) {
			throw new AbortException;
		}
	}

}

Then we register both services.

services:
	- AdminRequestMatcher
	- LoggedAdminFirewallListener

That's it!
