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

我在 Symfony 2.7.10 中使用资产，我想在控制器中生成一个图像 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，我添加了以下设置:

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 twig 中生成 url 工作正常，因此使用以下 twig 代码:

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

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

它产生:

/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

好吧，看到这个答案随着时间的推移得到了一些关注，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 中仍有基于版本的标记时添加了此答案，并且该问题最初是为 Sf2 添加的
• 从那以后，事情发生了很大变化，所以我要扩展答案

如何使用容器服务处理 Symfony 2.8.36 的资产 url:

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

public function indexAction(Request $request)
{
    /** @var SymfonyBundleFrameworkBundleTemplatingHelperAssetsHelper $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 Autowire 配置处理 Symfony 3.4.6 的资产 url:

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

public function indexAction(Request $request)
{
    /** @var SymfonyComponentAssetPackages $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, SymfonyComponentAssetPackages $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 Autowire 配置处理 Symfony 4.0 的资产 URL:

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

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

对于 Symfony 4，有几件事需要了解:

For Symfony 4 there are few things to know:

• 项目的框架略有变化，现在您必须包含您将需要的包.在这种情况下，默认情况下不包括资产管理，因此为了使该服务正常工作，您需要执行 composer require symfony/asset.

使用名为 templating.helper.assets 的辅助服务可以解决问题.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'));
