Gaufrette (带AWS) & Symfony 4-读一幅图

Question

下午好,

我试图显示来自AWS S3存储的图像。我使用了gaufrette文件配置，当我在AWS S3存储中上传文件时，它可以工作。

计量器配置：

knp_gaufrette:
    adapters:
        images:
            aws_s3:
                service_id: "infra.aws_s3.client"
                bucket_name: "%amazon_s3.bucket_name%"
                detect_content_type: true
                options:
                    directory: "%amazon_s3.directories.images%"
                    acl: public-read
        documents:
            aws_s3:
                service_id: "infra.aws_s3.client"
                bucket_name: "%amazon_s3.bucket_name%"
                detect_content_type: true
                options:
                    directory: "%amazon_s3.directories.documents%"
                    acl: public-read
        imports:
            aws_s3:
                service_id: "infra.aws_s3.client"
                bucket_name: "%amazon_s3.bucket_name%"
                detect_content_type: true
                options:
                    directory: "%amazon_s3.directories.imports%"
                    acl: public-read
    filesystems:
        images:
            adapter: images
            alias: images_filesystem
        documents:
            adapter: documents
            alias: documents_filesystem
        imports:
            adapter: imports
            alias: imports_filesystem

    public function __construct(
        PropertyPictureRepository $propertyPictureRepository,
        BuildingMediaRepository $buildingMediaRepository,
        Filesystem $awsS3,
        SerializerInterface $serializer,
        CommandBus $commandBus
    ) {
        $this->propertyPictureRepository = $propertyPictureRepository;
        $this->buildingMediaRepository = $buildingMediaRepository;
        $this->awsS3 = $awsS3;

        parent::__construct($serializer, $commandBus);
    }

    /**

     */
    public function propertyPictureReadAction(PropertyPicture $propertyPicture): BinaryFileResponse
    {
        $adapter = $this->awsS3->getAdapter();

        $filePath = $adapter->read(
            'group'.DIRECTORY_SEPARATOR.
            $this->getUser()->getGroupId().DIRECTORY_SEPARATOR.
            'property'.DIRECTORY_SEPARATOR.
            $propertyPicture->getProperty()->getIdValue().DIRECTORY_SEPARATOR.
            $propertyPicture->getFilename()
        );

        $response = new BinaryFileResponse($filepath);
        $response->headers->set('Content-Type', 'image/jpeg');
        $response->setContentDisposition(
            ResponseHeaderBag::DISPOSITION_INLINE,
            $propertyPicture->getFilename()
        );

        return $response;
    }
}

如果我尝试使用getLink() from $propertyPicture (该方法返回保存在数据库中的文件URL )，BinaryFileResponse就不会从给定的$propertyPicture中找到该文件。

我需要有来自Gaufrette的文件URL来在API响应中显示该文件。

在尝试了许多可能的解决方案之后，我已经找到了一个用于图片的解决方案(而且它工作得很好，即使在AWS S3中使用私有桶也是如此)：

<?php

namespace App\Application\Controller;

use App\Application\Controller\Rest\RestController;
use App\Domain\Entity\BuildingMedia;
use App\Domain\Entity\PropertyPicture;
use App\Infrastructure\Command\Command\CommandBus;
use App\Infrastructure\Repository\BuildingMediaRepository;
use App\Infrastructure\Repository\PropertyPictureRepository;
use Gaufrette\Filesystem;
use JMS\Serializer\SerializerInterface;
use Symfony\Component\HttpFoundation\Response;
use Swagger\Annotations as SWG;
use Nelmio\ApiDocBundle\Annotation\Operation;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\ParamConverter;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Security;
use Symfony\Component\HttpKernel\Exception\HttpException;

class MediaController extends RestController
{
    /**
     * @var PropertyPictureRepository
     */
    private $propertyPictureRepository;

    /**
     * @var BuildingMediaRepository
     */
    private $buildingMediaRepository;

    /**
     * @var Filesystem
     */
    private $awsS3;

    /**

     * @param SerializerInterface       $serializer
     * @param CommandBus                $commandBus
     */
    public function __construct(
        PropertyPictureRepository $propertyPictureRepository,
        BuildingMediaRepository $buildingMediaRepository,
        Filesystem $awsS3,
        SerializerInterface $serializer,
        CommandBus $commandBus
    ) {
        $this->propertyPictureRepository = $propertyPictureRepository;
        $this->buildingMediaRepository = $buildingMediaRepository;
        $this->awsS3 = $awsS3;

        parent::__construct($serializer, $commandBus);
    }

    /**
     * @Operation(
     *     tags={"Media"},
     *     summary="Read a property's picture.",
     *     @SWG\Response(

     *         description="OK"
     *     ),
     *     @SWG\Response(
     *         response="400",
     *         description="Bad request"
     *     ),
     *     @SWG\Response(
     *         response="401",
     *         description="Unauthorized"
     *     ),
     *     @SWG\Response(
     *         response="403",
     *         description="Access denied"
     *     ),

     * )
     *
     * @ParamConverter("propertyPicture", converter="property_picture")
     *
     * @param PropertyPicture $propertyPicture
     *
     * @return Response
     */
    public function propertyPictureReadAction(PropertyPicture $propertyPicture): Response
    {
        $adapter = $this->awsS3->getAdapter();

        $content = $adapter->read(
            'group'.DIRECTORY_SEPARATOR.
            $this->getUser()->getGroupId().DIRECTORY_SEPARATOR.
            'property'.DIRECTORY_SEPARATOR.
            $propertyPicture->getProperty()->getIdValue().DIRECTORY_SEPARATOR.
            $propertyPicture->getFilename()
        );

        return new Response($content, 200, array(
                'Content-Type' => 'image/jpeg'
        ));
    }
}

read()方法从Gaufrette返回文件内容，而不是真正的路径。因此，我只需将返回值从BinaryFileResponse更改为Response，并手动设置Content-Type。

下一次升级，如果您有相同的处理，是在保存文件时在数据库中设置MIME类型，并在需要使用API中类似的路由显示它时返回它。
