laravel API不示出了从请求验证消息

Question

具有带我的后端laravel API错误处理程序问题IM，不从验证显示错误消息。

路线/ API

<?php
Route::group([

    'middleware' => 'api',

], function ($router) {
    Route::post('access/sign-up', 'AuthenticationController@signUp');
});

AuthenticationController

<?php

namespace App\Http\Controllers;

use Illuminate\Support\Facades\Auth;
use App\Http\Controllers\Controller;
use App\Http\Requests\SignUpRequest;
use Illuminate\Http\Request;
use App\User;


    class AuthenticationController extends Controller
    {
        /**
         * Create a new AuthenticationController instance.
         *
         * @return void
         */
        public function __construct()
        {
            $this->middleware('auth:api', ['except' => ['signUp']]);
        }


        /**
         * 
         *
         * @return \Illuminate\Http\JsonResponse
         */
        public function signUp(SignUpRequest $request)
        {
            //User::create($request->all());
            return response()->json([
                'data' => 'Usuario creado correctamente.'
            ]);
        }
    }

SignUpRequest

<?php

namespace App\Http\Requests;

use Illuminate\Foundation\Http\FormRequest;

class SignUpRequest extends FormRequest
{
    /**
     * Determine if the user is authorized to make this request.
     *
     * @return bool
     */
    public function authorize()
    {
        return true;
    }

    /**
     * Get the validation rules that apply to the request.
     *
     * @return array
     */
    public function rules()
    {
        return [
            'email' => 'required|email|unique:users',
            'firstName' => 'required',
            'password' => 'required',
        ];
    }


}

问题是，当邮递员我在空白发送密码或不发送，例如邮件发给我的主网页insted的给我一个JSON的所有像以前一样的错误。我不知道该怎么办。我tryed与SignUpRequest自定义消息，但是这不是问题，认为某种重定向的错误处理程序。

Answer 1

使用表单请求;如果验证失败，重定向响应，将产生用户发送回他们以前的位置。这就是为什么要重定向回页面，而不是响应JSON。

Laravel有一个保护法“failedValidation”的方法。覆盖在你的形式请求类此方法。

  protected function failedValidation(\Illuminate\Contracts\Validation\Validator $validator)
{

    throw new \Illuminate\Validation\ValidationException(response()->json($validator->errors(), 422));
}

Answer 2

只需添加该代码SignUpRequest

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



protected function failedValidation(Validator $validator)
{
    throw new HttpResponseException(response()->json($validator->errors(), 422));
}
