symfony 4.3，带有vich捆绑包的api平台-如何上传多个文件

问题描述 投票：0回答：1

我创建了一个具有一对多关系图像实体的demo1实体，并使用vich捆绑包进行上传

Demo1隐私

<?php

namespace App\Entity;

use ApiPlatform\Core\Annotation\ApiResource;
use Doctrine\Common\Collections\ArrayCollection;
use Doctrine\Common\Collections\Collection;
use Doctrine\ORM\Mapping as ORM;

use App\Controller\UploadImageAction;

/**
 * @ORM\Entity(repositoryClass="App\Repository\Demo1Repository")
 * @ApiResource(
 *     collectionOperations={
 *             "get",
 *              "post" ={
 *
 *                    "controller"=UploadImageAction::class,
 *                    "defaults"={"_api_receive"=false},
 *                    "denormalization_context"={"groups"={"image"}}
 *              }
 *     }
 * )
 */
class Demo1
{
    /**
     * @ORM\Id()

     * @ORM\Column(type="integer")
     */
    private $id;

    /**
     * @ORM\OneToMany(targetEntity="App\Entity\Image", mappedBy="myfiles")
     * @ORM\JoinColumn(nullable=false);
     */
    private $files;

    public function __construct()
    {
        $this->files = new ArrayCollection();
    }

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

    /**
     * @return Collection|Image[]
     */
    public function getFiles(): Collection
    {
        return $this->files;
    }

    public function addFile(Image $file): self
    {
        if (!$this->files->contains($file)) {
            $this->files[] = $file;
            $file->setMyfiles($this);
        }

        return $this;
    }

    public function removeFile(Image $file): self
    {
        if ($this->files->contains($file)) {
            $this->files->removeElement($file);
            // set the owning side to null (unless already changed)
            if ($file->getMyfiles() === $this) {
                $file->setMyfiles(null);
            }
        }

        return $this;
    }
}

ImageType（窗体）

class ImageType extends AbstractType
{
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder->add('files', FileType::class, [
            'multiple'=>true,
            'attr'     => [
                'accept' => 'image/*',
            ]

        ]);
    }
    public function configureOptions(OptionsResolver $resolver)
    {
        $resolver->setDefaults([
            'data_class' => Demo1::class,
            'csrf_protection' => false
        ]);
    }
    public function getBlockPrefix()
    {
        return '';
    }
}

上载动作

<?php


namespace App\Controller;


use ApiPlatform\Core\Validator\Exception\ValidationException;
use ApiPlatform\Core\Validator\ValidatorInterface;
use App\Entity\Demo1;
use App\Entity\Image;
use App\Form\ImageType;
use Doctrine\ORM\EntityManagerInterface;
use Symfony\Component\Form\FormFactoryInterface;
use Symfony\Component\HttpFoundation\Request;

class UploadImageAction
{

    /**
     * @var FormFactoryInterface
     */
    private $formFactory;
    /**
     * @var EntityManagerInterface
     */
    private $entityManager;
    /**
     * @var ValidatorInterface
     */
    private $validator;

    public function __construct(
        FormFactoryInterface $formFactory,
        EntityManagerInterface $entityManager,
        ValidatorInterface $validator
    )
    {

        $this->formFactory = $formFactory;
        $this->entityManager = $entityManager;
        $this->validator = $validator;
    }

    public function __invoke(Request $request)
    {
        // Create a new Image instance
        $image = new Demo1();
        // Validate the form
        $form = $this->formFactory->create(ImageType::class, $image);
        $form->handleRequest($request);
       // dump($request);
        if ($form->isSubmitted() && $form->isValid()){
            // Persist the new Image entity

            $this->entityManager->persist($image);
            $this->entityManager->flush();

           // $image->setFiles(null);

            return $image;


        }


        // Uploading done for us in background by VichUploader

        // Throw an validation exception, that means something went wrong during
        // form validation
        throw new ValidationException(
            $this->validator->validate($image)
        );


    }
}

如果有使用平台API上传多个文件的替代解决方案，建议当前代码不上传文件也不更新图像表

php symfony doctrine-orm doctrine api-platform.com
