php - 验证请求中的验证钩子后

Question

我可以在验证钩子（文档）之后附加到我的定制请求php artisan make:request吗？

您可以像这样覆盖getValidatorInstance()自定义请求类中的方法：

protected function getValidatorInstance()
{
   $validator = parent::getValidatorInstance();

   // here you can apply hook (example hook taken from documentation):

    $validator->after(function ($validator) {
       if ($this->somethingElseIsInvalid()) {
          $validator->errors()->add('field', 'Something is wrong with this field!');
       }
   });

   return $validator;
}
