验证请求后验证钩子

Question

我可以在验证钩子（documentation）后用php artisan make:request附加到我的定制请求吗？

Answer 1

您可以在自定义请求类中覆盖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;
}
