如何在Symfony控制器中获取资产img URL [英] How to get assets img url in Symfony controller

问题描述

我正在使用Symfony 2.7.10中的资产，并且想要在控制器中生成图像url.

I'm using assets in Symfony 2.7.10 and I want to generate an image url in the controller.

在symfony config.yml文件中，添加了以下设置:

In the symfony config.yml file I have added the following setting:

framework:
    assets:
          version: '311nk2'
          version_format: '%%s?v=%%s'
          base_path: /bundles/myBundleName

在树枝中，可以正常生成网址，因此使用以下树枝代码即可:

In twig the generating of an url works ok, so with the following twig code:

{{ asset('images/logo.png') }}

它生成:

/bundles/myBundleName/images/logo.png?v=311nk2

现在我想在控制器中生成相同的url，这怎么可能?

Now I want to generate the same url in a controller, how is this possible?

推荐答案

好的，看到这个答案随着时间的流逝得到了一点关注，我应该指出两点:

All right, seeing that this answer get a little bit of attention over the time, I should point out two things:

• 当我们在SO中仍具有基于版本的标记时，便添加了此答案，而该问题最初是为Sf2添加的.
• 从那时起，情况发生了很大变化，所以我要扩大答案

如何使用Container服务处理 Symfony 2.8.36 的资产网址:

How to handle asset url for Symfony 2.8.36 using the Container service:

public function indexAction(Request $request)
{
    /** @var \Symfony\Bundle\FrameworkBundle\Templating\Helper\AssetsHelper $manager */
    $manager = $this->get('templating.helper.assets');

    return $this->render('default/index.html.twig', array(
        'base_dir' => realpath($this->container->getParameter('kernel.root_dir').'/..').DIRECTORY_SEPARATOR,
        'logo' => $manager->getUrl('bundles/myBundleName/images/logo.png'),
    ));
}

如何使用容器服务和新的自动装配配置来处理 Symfony 3.4.6 的资产网址:

How to handle asset url for Symfony 3.4.6 using Container service and the new Autowire configuration:

public function indexAction(Request $request)
{
    /** @var \Symfony\Component\Asset\Packages $manager */
    $manager = $this->get('assets.packages');

    return $this->render('default/index.html.twig', [
        'base_dir' => realpath($this->getParameter('kernel.project_dir')).DIRECTORY_SEPARATOR,
        'logo' => $manager->getUrl('bundles/myBundleName/images/logo.png'),
    ]);
}

和

public function autowireAction(Request $request, \Symfony\Component\Asset\Packages $assetsManager)
{
    return $this->render('default/index.html.twig', [
        'base_dir' => realpath($this->getParameter('kernel.project_dir')).DIRECTORY_SEPARATOR,
        'logo' => $assetsManager->getUrl('bundles/myBundleName/images/logo.png'),
    ]);
}

如何仅使用自动装配配置来处理Symfony 4.0的资产网址:

How to handle asset url for Symfony 4.0 only with Autowire configuration:

public function indexAction(Request $request, \Symfony\Component\Asset\Packages $assetsManager)
{
    $path = $assetsManager->getUrl('bundles/myBundleName/images/logo.png');
}

对于Symfony 4，有几件事要知道:

For Symfony 4 there are few things to know:

• 该项目的框架已经发生了一些变化，现在您必须包含所需的软件包.在这种情况下，默认情况下不包括资产管理，因此，要使此服务正常工作，您需要执行composer require symfony/asset.

使用名为templating.helper.assets的帮助程序服务可以解决问题. 尝试这样的事情:

Using the helper service called templating.helper.assets could do the trick. Try something like this:

var_dump($this->get('templating.helper.assets')->getUrl('bundles/myBundleName/images/logo.png'));
