我正在尝试通过我的用户实体上的vichuploader 包上传文件。使用实现UserInterface的hwioauthbundle，我认为错误来自那个包......所以每次我尝试上传一个文件时，我都会遇到这个异常：

'Symfony\Component\HttpFoundation\File\UploadedFile' 的序列化是不允许的

我已经尝试过这个解决方案，但也有同样的例外。

您正在ImageFile此代码中序列化实体，这就是您收到错误的原因，请尝试删除该错误并添加updatedAt字段，以便学说可以跟踪实体的更改：

/**

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

     *

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;
}

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，也就是一个不允许被序列化的文件流。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）
