(Symfony 4)如何从PHP代码中访问Liip Imagine捆绑包?
我希望能够上传一个文件,并从中创建3个缩略图,并将所有内容存储在S3服务器上 我的liip/LiipImagineBundle设置如下: 想象一下:(Symfony 4)如何从PHP代码中访问Liip Imagine捆绑包?,symfony,thumbnails,Symfony,Thumbnails,我希望能够上传一个文件,并从中创建3个缩略图,并将所有内容存储在S3服务器上 我的liip/LiipImagineBundle设置如下: 想象一下: # configure resolvers resolvers : # setup the default resolver default : # use the default web path web_path : ~ # your filter sets are defined here

这是我正在查看的文档:
我遇到的问题是,在文档中,它只是说按如下方式执行:
$this['imagine']->过滤器('/relative/path/to/image.jpg','my_thumb')
我得到的明显错误是:
无法将App\Controller\CreatorDashboard\PostsController类型的对象用作数组
我理解为什么会出现错误,它认为我试图将控制器类用作数组
但是如何在代码中访问这个Liip/LiipImagineBundle呢?如何在Symfony 4中获得“句柄”
文件不清楚 似乎只有在PHP模板中使用
$this['imagine']
时才使用它。要在控制器或服务中使用它,您可以从容器中获取它(使用服务的旧样式),手动将其注入类中(在带有@liip\u imagine.service.filter
的service.yaml文件中),或者使用它提供的class-as-a-service-name,以同样的方式,您可以键入来自请求对象、LoggerInterface或Symfony 3.3+中大多数其他内容的任何提示(来自出现在Liip\ImagineBundle\Service\FilterService
类中的代码)。您共享的示例用于不带细枝的模板使用。如果您在控制器中(基于您共享的错误的假设),则需要将Liip缓存管理器从容器中取出
/** @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)
如果您想在intance服务(或控制器)中使用它,可以插入Liip\ImagineBundle\Imagine\Cache\CacheManager
并在课堂上使用它:
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;
}
谢谢harmstyler,成功了。我在想,你是如何让它在服务课上发挥作用的?因为我希望遵循最佳实践并尽可能使控制器轻。必须将其作为id为
liip\u imagine.cache.manager的参数传递
