问题

我尝试通过API平台上传文件：

我按照文档操作，但出现了以下错误：

"类 "App\\Entity\\MediaObject" 无法上传。如果您使用属性来配置VichUploaderBundle，您可能忘记在实体顶部添加 `#[Vich\\Uploadable]`。如果您不使用属性，请检查配置文件是否放置正确。在这两种情况下，清除缓存也可以解决问题。"

我使用的版本如下：

"api-platform/core": "^3.0",
"vich/uploader-bundle": "^2.0"

我的配置如下：

# api/config/packages/vich_uploader.yaml
vich_uploader:
  db_driver: orm
  metadata:
    type: attribute
  mappings:
    media_object:
      uri_prefix: /media
      upload_destination: '%kernel.project_dir%/public/media'
      namer: Vich\UploaderBundle\Naming\OrignameNamer

我的实体如下：

                            ]
                        ]
                    ]
                ]
            ]
        )
    ]
)]
class MediaObject
{
    #[ORM\Id, ORM\Column, ORM\GeneratedValue]
    private ?int $id = null;

    #[ApiProperty(types: ['https://schema.org/contentUrl'])]
    #[Groups(['media_object:read'])]
    public ?string $contentUrl = null;

    #[Vich\UploadableField(mapping: "media_object", fileNameProperty: "filePath")]

    public ?string $filePath = null;

    public function getId(): ?int
    {
        return $this->id;
    }
}

请注意，文档中的错误信息已经被翻译成中文。

"The class \"App\\Entity\\MediaObject\" is not uploadable. If you use attributes to configure VichUploaderBundle, you probably just forgot to add `#[Vich\\Uploadable]` on top of your entity. If you don't use attributes, check that the configuration files are in the right place. In both cases, clearing the cache can also solve the issue.",
