当我使用带有验证的 vich 上传器上传图像时,它将返回“imageName 不应为空”错误消息。我无法弄清楚它造成这种情况的原因。
Vich 上传器配置:
vich_uploader:
db_driver: orm
mappings:
home_partner_alliance:
uri_prefix: /image/home/partnerAlliance
upload_destination: '%kernel.project_dir%/public/image/home/partnerAlliance'
我的控制器:
/*
--- router annotation ---
*/
public function addImage(Request $request, ValidatorInterface $validator)
{
$file = $request->files->get('image');
$home = new HomePartnerAlliance();
$home->setImageFile($file);
$home->setUpdatedAt(new \DateTime());
$errors = $validator->validate($home);
if(count($errors) == 0){
$this->em->persist($home);
$this->em->flush();
}
else
{
$messages = [];
foreach($errors as $error)
{
$messages[$error->getPropertyPath()] = $error->getMessage();
}
}
return new JsonResponse(['status'=> $messages]);
}
我的实体:
<?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\HomePartnerAllianceRepository")
* @Vich\Uploadable
*/
class HomePartnerAlliance
{
/**
* @ORM\Id()
* @ORM\GeneratedValue()
* @ORM\Column(type="integer")
*/
private $id;
/**
* @Vich\UploadableField(mapping="home_partner_alliance", fileNameProperty="imageName")
* @Assert\File(mimeTypes = {"image/jpeg", "image/png"})
*/
private $imageFile;
/**
* @ORM\Column(type="string", length=255)
*/
private $imageName;
/**
* @ORM\Column(type="date")
*/
private $updatedAt;
public function getId(): ?int
{
return $this->id;
}
public function setImageFile(?File $imageFile = null): void
{
$this->imageFile = $imageFile;
if (null !== $imageFile) {
// 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->updatedAt = new \DateTime();
}
}
public function getImageFile(): ?File
{
return $this->imageFile;
}
public function getImageName(): ?string
{
return $this->imageName;
}
public function setImageName(?string $imageName): self
{
$this->imageName = $imageName;
return $this;
}
public function getUpdatedAt(): ?\DateTimeInterface
{
return $this->updatedAt;
}
public function setUpdatedAt(\DateTimeInterface $updatedAt): self
{
$this->updatedAt = $updatedAt;
return $this;
}
}
因此,当我将图像发布到控制器时,它会返回一条错误消息:
{
"status": {
"imageName": "This value should not be null."
}
}
我尝试上传无效类型的文件,它也会返回 imageName Null:
{
"status": {
"imageFile": "The mime type of the file is invalid (\"image\/vnd.adobe.photoshop\"). Allowed mime types are \"image\/jpeg\", \"image\/png\".",
"imageName": "This value should not be null."
}
}
但是当我删除控制器中的验证代码时,它成功地将图像添加到文件夹中,并且图像名称被保存到数据库中。这个问题有什么解决办法吗?
