记录Laravel 定义API 统一返回JSON响应和错误格式

<?php

namespace App\Http\Requests;

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

class BaseRequest extends FormRequest
{
    // 定义统一的返回错误格式,下面的可以不定义
    protected function failedValidation(Validator $validator)
    {
      throw(new HttpResponseException(response()->json([
          'code'=>422,
          'msg'=>$validator->errors(),
          'data'=>null
      ],422)));
    }


    // 是否所有response 都是JSON 返回
    public function expectsJson()
    {
        return true;
    }
    public function wantsJson()
    {
        return true;
    }
}

$response = $kernel->handle(
    $request = \App\Http\Requests\BaseRequest::capture()
);
