dingo 的 request 报错,如何按照自己的格式报错呢?

vendor/dingo/api/src/Http/FormRequest.php

<?php

namespace Dingo\Api\Http;

use Illuminate\Contracts\Validation\Validator;
use Dingo\Api\Exception\ValidationHttpException;
use Symfony\Component\HttpKernel\Exception\HttpException;
use Illuminate\Foundation\Http\FormRequest as IlluminateFormRequest;

class FormRequest extends IlluminateFormRequest
{
    /**
     * Handle a failed validation attempt.
     *
     * @param \Illuminate\Contracts\Validation\Validator $validator
     *
     * @return void
     */
    protected function failedValidation(Validator $validator)
    {
        if ($this->container['request'] instanceof Request) {
            throw new ValidationHttpException($validator->errors());
        }

        parent::failedValidation($validator);
    }

    /**
     * Handle a failed authorization attempt.
     *
     * @return void
     */
    protected function failedAuthorization()
    {
        if ($this->container['request'] instanceof Request) {
            throw new HttpException(403);
        }

        parent::failedAuthorization();
    }
}

你看看 FormRequest.php 的代码，自己定义 failedValidation
