如何在 symfony2 服务中执行 $this->render() ? [英] how to perform $this->render() inside symfony2 service?

问题描述

我在一个普通的 symfony2 控制器中有这个代码:

I have this code inside a normal symfony2 controller:

            $temp = $this->render('BizTVArchiveBundle:ContentTemplate:'.$content[$i]['template'].'/view.html.twig', array(
                'c'=> $content[$i],
                'ordernumber' => 1,
            ));

而且效果很好.

现在我正在尝试将其移至服务，但我不知道如何访问普通控制器的 $this 等效项.

Now I am trying to move this to a service, but I don't know how to access the equivalent of $this of the normal controller.

我尝试像这样注入容器:

I tried injecting the container like this:

    $systemContainer = $this->container;

    $temp = $systemContainer->render('BizTVArchiveBundle:ContentTemplate:'.$content[$i]['template'].'/view.html.twig', array(
                'c'=> $content[$i],
                'ordernumber' => 1,
            ));

但是那没有用，我想那是因为 render 并没有真正使用普通控制器的 $this-> 容器，而只是使用了 $this 部分.

But that didn't work, and I guess that is because render isn't really using the $this->container of the normal controller but only using the $this part.

有人知道如何从服务中使用 $this->render() 吗?

Anyone know how to use $this->render() from a service?

推荐答案

检查Symfony\Bundle\FrameworkBundle\Controller类中的render方法.它说:

Check method render in Symfony\Bundle\FrameworkBundle\Controller class. It says:

return $this->container->get('templating')->render($view, $parameters);

因此，由于您的服务中已经有容器，因此您可以像上面的示例一样使用它.

so since you have container already in your service you can use it like in above example.

注意:将整个容器注入服务被认为是不好的做法，在这种情况下，您应该只注入模板引擎，并在模板对象上调用 render 方法.

NOTE: injecting whole container into service is considered as bad practice, you should inject only templating engine in this case and call render method on templating object.

如此完整的图片:

services.yml:

services:
    your_service_name:
        class: Acme\YourSeviceClass
        arguments: [@templating]

你的班级:

public function __construct($templating)
{ 
    $this->templating = $templating
}

和您的渲染调用:

$this->templating->render($view, $parameters)
