php - 合并验证错误并返回一条消息

Question

我有两个数组要在我的自定义 Request 中验证:

$rules = [
  'params.words1.*.value' => 'required|string|between:5,50',
  'params.words2.*.value' => 'required|string|between:5,50',
];

这将返回每个单词的错误消息。但我想要一个单一的一般信息，比如“有些词是无效的”。
有没有 Laravel 的方式来做到这一点？

你可以这样做:

$messages = [
    'params.*' => 'Some of the words are invalid.',
];

我想我可能已经找到了解决方案:

首先，确保在顶部导入 Validator 和 HttpResponseException:

use Illuminate\Contracts\Validation\Validator;
use Illuminate\Http\Exceptions\HttpResponseException;

然后，您可以覆盖 native failedValidation方法并根据需要更改错误:

protected function failedValidation(Validator $validator)
{
    // Get all the errors thrown
    $errors = collect($validator->errors());
    // Manipulate however you want. I'm just getting the first one here,
    // but you can use whatever logic fits your needs.
    $error  = $errors->unique()->first();

    // Either throw the exception, or return it any other way.
    throw new HttpResponseException(response(
        $error,
        422
    ));
}
