如何在api-platform中“验证”DELETE请求

// 自定义验证器类
use Symfony\Component\Validator\Constraints as Assert;
use Symfony\Component\Validator\Context\ExecutionContextInterface;

class DeleteRequestValidator
{
    /**
     * @Assert\Callback
     */
    public function validateDeleteRequest($data, ExecutionContextInterface $context)
    {
        // 验证逻辑
        if ($data->getParam() === null) {
            $context->buildViolation('Param cannot be null.')
                ->atPath('param')
                ->addViolation();
        }
    }
}

// 资源类
use ApiPlatform\Core\Annotation\ApiResource;
use Symfony\Component\Validator\Constraints as Assert;

/**
 * @ApiResource(
 *     collectionOperations={},
 *     itemOperations={
 *         "delete"={
 *             "method"="DELETE",
 *             "path"="/resources/{id}",
 *             "validation_groups"={"Default", "delete"}
 *         }
 *     }
 * )
 */
class Resource
{
    /**
     * @Assert\NotBlank(groups={"delete"})
     */
    private $param;

    // Getter 和 Setter 方法
}
