如何在使用自定义验证器解析器时使用验证名称和属性[laravel 6]

<?php

namespace App\Validation;

use Illuminate\Validation\Validator;

class CustomValidator extends Validator
{
    public function validateCustomRule($attribute, $value, $parameters)
    {
        // 自定义验证规则的逻辑
        // 可以使用 $this->validateAttribute 方法来验证属性的值

        // 示例：判断属性值是否为偶数
        if ($value % 2 != 0) {
            return false;
        }

        return true;
    }
}

<?php

namespace App\Providers;

use Illuminate\Support\ServiceProvider;
use Illuminate\Support\Facades\Validator;
use App\Validation\CustomValidator;

class AppServiceProvider extends ServiceProvider
{
    public function boot()
    {
        Validator::resolver(function ($translator, $data, $rules, $messages) {
            return new CustomValidator($translator, $data, $rules, $messages);
        });
    }
}

$rules = [
    'attribute' => 'custom_rule',
];
