我将 Vich Uploader Bundle 与 API Platform 结合使用来存储文件。我已按照官方文档https://api-platform.com/docs/core/file-upload/#handling-file-upload中的说明进行操作
一切正常，除了我想包含 PUT 调用来替换现有的 MediaObject 实体。我的尝试如下：
我创建了一个自定义操作并将其映射到实体中的 PUT 方法，如下所示：
<?php
// api/src/Entity/MediaObject.php
namespace App\Entity;
use ApiPlatform\Core\Annotation\ApiProperty;
use ApiPlatform\Core\Annotation\ApiResource;
use App\Controller\CreateMediaObject;
use App\Controller\EditMediaObject;
use Doctrine\ORM\Mapping as ORM;
use Symfony\Component\HttpFoundation\File\File;
use Symfony\Component\Serializer\Annotation\Groups;
use Symfony\Component\Validator\Constraints as Assert;
use Vich\UploaderBundle\Mapping\Annotation as Vich;
