我希望能够上传一个文件，并从它创建3缩略图和存储在S3服务器上的一切。
我的liip/LiipImagineBundle设置如下：
liip_imagine：

# configure resolvers
resolvers :
    # setup the default resolver
    default :
        # use the default web path
        web_path : ~
# your filter sets are defined here
filter_sets :
    # use the default cache configuration
    cache : ~
    # the name of the "filter set"
    my_thumb :
        # adjust the image quality to 75%
        quality : 75
        # list of transformations to apply (the "filters")
        filters :
            # create a thumbnail: set size to 120x90 and use the "outbound" mode
            # to crop the image when the size ratio of the input differs
            thumbnail  : { size : [120, 90], mode : outbound }
            # create a 2px black border: center the thumbnail on a black background
            # 4px larger to create a 2px border around the final image
            background : { size : [124, 94], position : center, color : '#000000' }
    # the name of the "filter set"
    thumb_square :
        # adjust the image quality to 75%
        quality : 75
        # list of transformations to apply (the "filters")
        filters :
            thumbnail :  { size : [300, 300], mode : outbound }
            # create a 2px black border: center the thumbnail on a black background
            # 4px larger to create a 2px border around the final image
            background : { size : [304, 304], position : center, color : '#000000' }
    # the name of the "filter set"
    thumb_rectangle_md :
        # adjust the image quality to 75%
        quality : 75
        # list of transformations to apply (the "filters")
        filters :
            thumbnail :  { size : [670, 400], mode : outbound }
            # create a 2px black border: center the thumbnail on a black background
            # 4px larger to create a 2px border around the final image
            background : { size : [674, 404], position : center, color : '#000000' }
    # the name of the "filter set"
    thumb_hd :
        # adjust the image quality to 75%
        quality : 75
        # list of transformations to apply (the "filters")
        filters :
            thumbnail :  { size : [1920, 1080], mode : outbound }
            # create a 2px black border: center the thumbnail on a black background
            # 4px larger to create a 2px border around the final image
            background : { size : [1924, 1084], position : center, color : '#000000' }

这是我正在查看的文档：https://symfony.com/doc/2.0/bundles/LiipImagineBundle/basic-usage.html#runtime-options
我遇到的问题是，在文档中，它只是说要像下面这样做：
$this['imagine']->filter('/relative/path/to/image.jpg', 'my_thumb')
我得到的最明显的错误是：
Cannot use object of type App\Controller\CreatorDashboard\PostsController as array
我明白为什么我得到的错误，它认为我试图使用我的控制器类作为一个数组。
但是你如何在代码中访问这个Liip/LiipImagineBundle呢？我如何在Symfony 4中获得它的“句柄”呢？
文件不清楚。

你分享的例子是不带twig的模板用法。如果你在一个控制器中（基于你分享的错误的假设），你需要从容器中获取Liip缓存管理器。

/** @var CacheManager */
$imagineCacheManager = $this->get('liip_imagine.cache.manager'); // gets the service from the container
/** @var string */
$resolvedPath = $imagineCacheManager->getBrowserPath('/relative/path/to/image.jpg', 'my_thumb'); // resolves the stored path

（在Symfony 5中测试过）如果你想在服务中使用它（或在控制器中），你可以注入Liip\ImagineBundle\Imagine\Cache\CacheManager并在你的类中使用它：

public function __construct(UploaderHelper $uploaderHelper, CacheManager $cacheManager)
{
    $this->uploaderHelper = $uploaderHelper;
    $this->cacheManager = $cacheManager;
}   
public function getImageLink($image)
{
    $imagePath = $this->uploaderHelper->asset($image, 'imageFile');
    $imageLink = $this->cacheManager->getBrowserPath($imagePath, $imagine_filter);
    return $imageLink;
}

$this['imagine']的使用似乎仅限于在PHP模板中使用它。如果在控制器或服务中使用它，您可以将其作为服务使用，或者从容器中获取它（使用服务的旧风格），手动将其注入类（在service.yaml文件中，使用@liip_imagine.service.filter），或者使用它提供的class-as-a-service-name，就像您从Request objec，LoggerInterface，或者Symfony 3.3+中的大多数其他东西（从代码来看，它出现在Liip\ImagineBundle\Service\FilterService类中）。

还测试了Symfony 6.3和liip/imagine-bundle 2.11

<?php
use Symfony\Bundle\FrameworkBundle\Controller\AbstractController;
use Symfony\Component\HttpFoundation\Response;
use Liip\ImagineBundle\Imagine\Cache\CacheManager;
class ItemController extends AbstractController{
    public function __construct(private readonly CacheManager $imagineCacheManager) {}
    #[Route('/list', name: 'list')]
    public function list(): Response {
        $pathRelative = '/uploads/images/image.png';
        $resolvedPath = $this->imagineCacheManager->generateUrl($pathRelative, 'my_thumb');
        $htmlString = '<img src="'.$resolvedPath.'" class="img-fluid img-thumbnail"   alt="..." >';
        return $this->render('item/list.html.twig', ['htmlString' => $htmlString,]);
    }
}
