如何在 Web MVC 應用程式中實現存取控制清單 (ACL) 和基於角色的存取？

class SecureContainer
{
    protected $target;
    protected $acl;

    public function __construct($target, $acl)
    {
        $this->target = $target;
        $this->acl = $acl;
    }

    public function __call($method, $arguments)
    {
        if (method_exists($this->target, $method)
            && $this->acl->isAllowed(get_class($this->target), $method))
        {
            return call_user_func_array([$this->target, $method], $arguments);
        }
    }
}

$currentUser = ...;
$controller = ...;
$acl = new AccessControlList($currentUser);

$controller = new SecureContainer($controller, $acl);
$controller->actionIndex(); // ACL-protected controller methods

$this->acl->isAllowed(
    $this->target->getPermissions(), // Get object permissions
    [$getter, $method] // Command
);
