我尝试通过我的用户实体上的vichuploader bundle上传文件。 使用实现UserInterface的hwioauthbundle，我认为错误来自该包... 因此，每当我尝试上传文件时，我都会遇到此异常：
序列化＆＃39; Symfony \ Component \ HttpFoundation \ File \ UploadedFile＆＃39; 不允许
我已经尝试了 this solution但也有同样的异常。

我的表单用户类型：
use AppBundle\Form\FilesType;
->add('cv',FilesType::class)
我的表单Filestype：
-> add('imageFile',
VichFileType::class, [
'required' => false,
'allow_delete' => true,
'download_link' => true,
'label' => false,
]);

您正在此代码中序列化ImageFile实体，这就是您收到错误的原因，尝试删除该实体并添加updatedAt字段，以便该原则可以跟踪实体的更改：

* Files
* @ORM\Table(name="files")
* @ORM\Entity(repositoryClass="AppBundle\Repository\FilesRepository")
* @Vich\Uploadable
*/
class Files implements \Serializable
{
/**

* @ORM\GeneratedValue(strategy="AUTO")

protected $id;

看看这个，你的一个用户关系有一个 UploadedFile 属性，它本质上是一个文件，又名文件流，不允许序列化。因此，您需要指定要序列化的内容：
https://symfony.com/doc/3.3/security/entity_provider.html
基本上你只需要序列化id，用户名和密码（三个是上面页面的示例代码）
答案 2 :(得分：0)
对于Symfony5
Class User implement UserInterface
public function __serialize(): array
{
return [
'id' => $this->id,
'email' => $this->email,
//......
];
}
public function __unserialize(array $serialized): User
{
$this->id = $serialized['id'];
$this->email = $serialized['email'];
// .....
return $this;
}
