自定义控制器验证不起作用- Api-platform

Question

您好，我正在尝试验证用户实体验证，但只有一个带有补丁请求的属性，但我得到了Cannot validate values of type \"NULL\" automatically. Please provide a constraint.

即使从validation_groups中删除默认设置，也会得到相同的结果

非常感谢您的帮助。

App\Controller\PayingMembershipForOthersController

namespace App\Controller;

use ApiPlatform\Core\Validator\ValidatorInterface;
use App\Entity\User;
use Symfony\Component\HttpFoundation\Request;

class PayingMembershipForOthersController
{

    private ValidatorInterface $validator;

    public function __construct(ValidatorInterface $validator)
    {
        $this->validator = $validator;
    }

    public function __invoke(User $data, Request $request)
    {
        $this->validator->validate($data);
    }

}

所以我的目的是设置空值{"payForNewMember": ""}验证不显示违规列表

您的自定义控制器必须返回用户或响应。

class PayingMembershipForOthersController
{

    private ValidatorInterface $validator;

    public function __construct(ValidatorInterface $validator)
    {
        $this->validator = $validator;
    }

    public function __invoke(User $data)
    {
        $this->validator->validate($data);
        return $data;
    }

}
