Question

我正在尝试使用VichUploaderBundle通过dropzone上传文件，当我在$media->setFile($file)中完全分配文件时，我在控制器中收到以下错误：

Expected argument of type "string or null", "array" given

Dropzone HTML

<form action="{{path("media_dropzone")}}" class="dropzone" id="add_images_helpdesk" enctype="multipart/form-data">

<input type="hidden" name="entity" value="helpdesk" >

<input type="hidden" name="entityID" value="{{helpdesk.id}}" >

</form>

Dropzone jQuery

 var myDropzone = new Dropzone("#add_images_helpdesk", {
        url: $(this).attr("action"),
        addRemoveLinks: true
    });

我从dropzone获取ajax请求的控制器

/**
     * @Route("/dropzone", name="dropzone")
     * @Method({"GET", "POST"})
     */
    public function dropzone(Request $request)
    {
        $em       = $this->getDoctrine()->getManager();
        $file     = $request->files->get("file");
        $entity   = $request->request->get('entity');
        $entityId = $request->request->get('entityID');

       dump($file);

        $media = new Media();
        $media->setName("torre");
        $media->setFile($file);
        $media->setEntity($entity);
        $media->setEntityId($entityId);  
        $em->persist($media);
        $em->flush(); 


        // return data to the frontend
        return new JsonResponse([]);
    }

我在实体中分配文件的Setter。

<?php

namespace App\Entity;

use Doctrine\ORM\Mapping as ORM;
use Symfony\Component\HttpFoundation\File\File;
use Vich\UploaderBundle\Mapping\Annotation as Vich;
use Symfony\Component\Validator\Constraints as Assert;

    /**
     * @ORM\Entity(repositoryClass="App\Repository\MediaRepository")
     * @Vich\Uploadable
     */
    class Media
    {

     /**
         * 
         * @Vich\UploadableField(mapping="media", fileNameProperty="name", size="size",dimensions="dimensions")
         */
        private $file;

        public function setFile(?File $media = null): void
        {
            $this->file = $media;

            if (null !== $media) {
                // It is required that at least one field changes if you are using doctrine
                // otherwise the event listeners won't be called and the file is lost
                $this->createdAt = new \DateTime(date('Y-m-d H:i:s'));
            }

        }

有人可以告诉我为什么VichUploader没有处理它或它需要处理什么？

VichUploaderBundle + Dropzone类型＆＃34;字符串或null＆＃34;，＆＃34;数组＆＃34;的预期参数特定
