use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Symfony\Component\HttpFoundation\Response;

class InheritanceController extends Controller
{
    /**

     */
    public function inheritAction(){
        return new Response($this->render('article/list.html.twig'));
    }
}

my image folder is in root directory

Answer 1

仅当图像存在于web/images文件夹中时，才可以使用其默认配置的twig中的asset()函数，然后可以通过{{ asset('images/<image_name>') }}来调用任何图像

Answer 2

通过控制台安装资产： php app/console assets:install --symlink

Answer 3

方法$this->render()已经返回一个Response实例，只需将其更改为return $this->render(...)然后重试即可。
