我有自定義服務,我想在樹枝模板中使用它。 在Symfony的< 3我可以這樣做:如何在自定義服務中獲取Tempating或Container?
use Symfony\Component\DependencyInjection\Container;
//...
public function __construct(Container $container)
{
$this->container = $container;
}
public function getView()
{
$this->container->get('templating')->render('default/view.html.twig');
}
但在Symfony的3.3我有錯誤:
Cannot autowire service "AppBundle\Service\ViewService": argument "$container" of method "__construct()" references class "Symfony\Component\DependencyInjection\Container" but no such service exists. Try changing the type-hint to one of its parents: interface "Psr\Container\ContainerInterface", or interface "Symfony\Component\DependencyInjection\ContainerInterface".
謝謝,但你怎麼知道什麼接口使用?我在哪裏可以檢查它?如果我運行「bin/console debug:container」,那麼我有:'templating.engine.twig'的模板別名。那麼爲什麼和如何EngineInterface? – roggy
使用'bin/console debug:container templating'的@roggy會給你[提示自動裝配類型](https://i.stack.imgur.com/7fkeN.png)。 – jkucharovic
