Symfony 2 无法解决 Construct

Question

我遇到了这个错误

PHP Fatal error:  Uncaught exception 'Symfony\Component\Debug\Exception\ContextErrorException' with message 'Catchable Fatal Error: Argument 8 passed to Sonata\MediaBundle\Provider\ImageProvider::__construct() must implement interface Imagine\Image\ImagineInterface, none given, called in

我的服务：

sonata.media.provider.cropper:
    class: %cmy_sonata_media.custom_class_cropper%
    tags:
        - { name: sonata.media.provider }
    arguments:
        - sonata.media.provider.cropper
        - @sonata.media.filesystem.local
        - @sonata.media.cdn.server
        - @sonata.media.generator.default

        - ['image/jpeg', 'image/png']

    calls:
        - [ setTemplates, [ { helper_thumbnail: SonataMediaBundle:Provider:thumbnail.html.twig, helper_view: SonataMediaBundle:Provider:view_image.html.twig } ] ]

我的提供商

class ImageCropperProvider extends ImageProvider
{

protected $imagineAdapter;

/**

 */
public function __construct($name, Filesystem $filesystem, CDNInterface $cdn, GeneratorInterface $pathGenerator, ThumbnailInterface $thumbnail, array $allowedExtensions = array(), array $allowedMimeTypes = array(), ImagineInterface $adapter, MetadataBuilderInterface $metadata = null)
{

    parent::__construct($name, $filesystem, $cdn, $pathGenerator, $thumbnail, $allowedExtensions, $allowedMimeTypes, $metadata);

    $this->imagineAdapter = $adapter;
}

public function getProviderMetadata()
{
    return new Metadata($this->getName(), $this->getName().'.description', false, 'SonataMediaBundle', array('class' => 'fa fa-crop'));
}
}

我想做的是创建相同的 ImageProvider。但我不断收到该错误：我几乎尝试了一切。但总是以这个错误结束。也许我错过了什么。也许我的服务配置有误。但它与 ImageProvider 相同。所以应该没问题

Answer 1

你是不是忘记了 parent 的构造调用中的一个参数： $adapter 应该在 $allowedMimeTypes 和 $metadata

之间

如果您想之后再设置它，则为 null (...allowedMimeTypes, null, $metadata)

Answer 2

看来这是我的 api 缓存问题。清除所有缓存后解决。
