验证请求中的验证挂钩后

After validation hook in validation request

我可以使用 php artisan make:request 将验证挂钩 (documentation) 附加到我的自定义请求吗?

您可以在自定义请求 class 中覆盖 getValidatorInstance() 方法,如下所示:

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;
}
