Security Component - Core
|
||
|
|
=========================
|
||
|
|
|
||
|
|
Security provides an infrastructure for sophisticated authorization systems,
|
||
|
|
which makes it possible to easily separate the actual authorization logic from
|
||
|
|
so called user providers that hold the users credentials.
|
||
|
|
|
||
|
|
Getting Started
|
||
|
|
---------------
|
||
|
|
|
||
|
|
```bash
|
||
|
|
composer require symfony/security-core
|
||
|
|
```
|
||
|
|
|
||
|
|
```php
|
||
|
|
use Symfony\Component\Security\Core\Authentication\AuthenticationTrustResolver;
|
||
|
|
use Symfony\Component\Security\Core\Authentication\Token\UsernamePasswordToken;
|
||
|
|
use Symfony\Component\Security\Core\Authorization\AccessDecisionManager;
|
||
|
|
use Symfony\Component\Security\Core\Authorization\Voter\AuthenticatedVoter;
|
||
|
|
use Symfony\Component\Security\Core\Authorization\Voter\RoleVoter;
|
||
|
|
use Symfony\Component\Security\Core\Authorization\Voter\RoleHierarchyVoter;
|
||
|
|
use Symfony\Component\Security\Core\Exception\AccessDeniedException;
|
||
|
|
use Symfony\Component\Security\Core\Role\RoleHierarchy;
|
||
|
|
|
||
|
|
$accessDecisionManager = new AccessDecisionManager([
|
||
|
|
new AuthenticatedVoter(new AuthenticationTrustResolver()),
|
||
|
|
new RoleVoter(),
|
||
|
|
new RoleHierarchyVoter(new RoleHierarchy([
|
||
|
|
'ROLE_ADMIN' => ['ROLE_USER'],
|
||
|
|
]))
|
||
|
|
]);
|
||
|
|
|
||
|
|
$user = new \App\Entity\User(...);
|
||
|
|
$token = new UsernamePasswordToken($user, 'main', $user->getRoles());
|
||
|
|
|
||
|
|
if (!$accessDecisionManager->decide($token, ['ROLE_ADMIN'])) {
|
||
|
|
throw new AccessDeniedException();
|
||
|
|
}
|
||
|
|
```
