VichUploader：MediaObject 不可上传

Question

我尝试使用 API 平台通过 REST API 上传文件

我跟着医生，但我得到了：

"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.",

我正在使用：

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

我的配置：

# 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：

// api/src/Entity/MediaObject.php

Answer 1

就我而言，这解决了问题：

composer require doctrine/annotations

Answer 2

就我而言，将元数据类型设置为属性解决了问题。

   vich_uploader:
        metadata:
            type: attribute
