表單驗(yàn)證在日常工作中經(jīng)常用到,如果我們是創(chuàng)建了自定義驗(yàn)證類 而又想手動(dòng)捕獲錯(cuò)誤消息,那么在新建的驗(yàn)證類里面寫如下方法即可,此方法會(huì)覆蓋掉繼承的FormRequest基類方法,當(dāng)然了如果你整個(gè)項(xiàng)目都需要用某種錯(cuò)誤返回的方法,直接修改基類的方法也可以.

namespace App\Http\Requests;

use Illuminate\Foundation\Http\FormRequest;
use Illuminate\Validation\ValidationException;
use Illuminate\Contracts\Validation\Validator;
use Illuminate\Http\Response;

public function failedValidation(Validator $validator)
    {
//后來添加的
        $data = [
            'code' => 422,
            'msg' => $validator->errors()->first(),
            'data' => $validator->errors()
        ];

        $respone = new Response(json_encode($data));


//下面是框架自帶的

        throw (new ValidationException($validator, $respone))
            ->errorBag($this->errorBag)
            ->redirectTo($this->getRedirectUrl());
    }
