大家好，我正在尝试做一张表格来修改个人资料的图像。一切正常，但是当我放大尺寸的图像（除数据库中的图像以外，我的图像超出了我所有的图像）时，就会出现此错误：
不允许对“ Symfony \ Component \ HttpFoundation \ File \ UploadedFile”进行序列化
我不知道为什么约束不起作用...（在我创建配置文件时有效，但在我对其进行修改时无效）
我将代码放在此处：（控制器）
$loggedAs = $this->getUser();
$avatar_profile = $loggedAs->getAvatarPath();
$em = $this->getDoctrine()->getManager();
$form = $this->createForm(ProfileModificationType::class, $loggedAs);
$form->handleRequest($request);
if ($form->isSubmitted() && $form->isValid()) {
/**
* @var UploadedFile $file
*/
$file = $form->get('avatarPath')->getData();
if ($file != NULL) {
$fileName = md5(uniqid()) . '.' . $file->guessExtension();
$file->move(
$this->getParameter('image_directory'), $fileName
);
$loggedAs->setAvatarPath($fileName);
} else {
$loggedAs->setAvatarPath($avatar_profile);
}
$loggedAs->setSalt(md5(uniqid()));
$loggedAs->setPassword($encoder->encodePassword($loggedAs, $loggedAs->getPassword()));
$em->flush();
$this->get('session')->getFlashBag()->add('success', "Votre compte a été modifié");
表格：
->add('avatarPath', FileType::class, array(
'data_class' => null,
'required' => false,
'label' => 'Avatar',
'constraints' => array(
new Assert\Image(array(
'maxHeight' => 600,
'maxWidth' => 600,
'maxSize' => 1000000,
'maxHeightMessage' => 'Longeur maximale de 600Px',
'maxWidthMessage' => 'Largeur maximale de 600Px',
'maxSizeMessage' => 'Taille maximale de 1Mo',
))),
'invalid_message' => 'Cette valeur est invalide',
));
以及我的实体资料（约束）：
public static function loadValidatorMetadata(ClassMetadata $metadata)
{
$metadata->addPropertyConstraint('avatarPath', new Assert\Image(array(
'maxHeight' => 600,
'maxWidth' => 600,
'maxSize' => 1000000,
'maxHeightMessage' => 'Longeur maximale de 600Px',
'maxWidthMessage' => 'Largeur maximale de 600Px',
'maxSizeMessage' => 'Taille maximale de 1Mo',
)));
}
和我的实体
/**
* @var string
*
* @ORM\Column(name="avatar_path", type="string", length=255, nullable=false)
*/
private $avatarPath;
当我修改实体时，我尝试序列化该实体，但是我遇到了同样的错误……也许我做错了，我把为序列化而更改的代码放给您。

也许可以在Java脚本或其他内容中添加约束，因为当我放置一个具有约束的良好尺寸的图像时，将不会出现错误，甚至不会出现在刷新前调整图像大小和设置图像大小的方法:)感谢任何尝试提供帮助的人
答案 0 :(得分：0)
也许您可以按照docs中所述使用注释直接将约束添加到Profile类：
/**
* @ORM\Column(name="avatar_path", type="string", length=255, nullable=false)
* @Assert\File(
* maxSize="1M",
* maxSizeMessage="Taille maximale de 1Mb")
*/
private $avatarPath;
