SLIM Separating out route from function using TWIG

如果我想将路由从函数中分离出来，最好的方法是什么，因为我仍然需要use($app,$twig)

$app->get('/app(/:date(/:time))', function ($date = null,$time = null) use ($app,$twig)     {       
    //do some stuff using TWIG
}); 
 $app->run();

新路线，功能function app(...

$app->get('/app(/:date(/:time))', 'app');

编辑1-下一步尝试使用一个类给出一个"未定义的变量：trick">

$actions = new Actions($app, $twig);
$app->get('/app(/:date(/:time))', [$actions, 'app']);   
$app->run();

class Actions {
    protected $app, $twig;
    public function __construct($app, $twig) {
        $this->app  = $app;
        $this->twig = $twig;
    }
    public function app($date = null,$time = null) {
        // print_r($:date);
    //  get some data using date time
        $template = $twig->loadTemplate('template.php');
            echo $template->render(array(
            ........
            ));
    }
}

$appFunc = function () use ($app, $twig) ...
$app->get(..., $appFunc);

或：

class Actions {
    protected $app, $twig;
    public function __construct($app, $twig) {
        $this->app  = $app;
        $this->twig = $twig;
    }
    public function app() ...
}
$actions = new Actions($app, $twig);
$app->get(..., [$actions, 'app']);

或：

function app($app, $twig) {
    return function () use ($app, $twig) ...
}
$app->get(..., app($app, $twig));
