Laravel 5.5 FormRequest 自定义错误消息

　　使用FormRequest进行表单验证，就不用让验证逻辑和控制器里面的逻辑都混在一起。但在使用的时候呢，发现json错误返回的数据，与我们想要的有点差距。下面我给个例子：（不喜勿喷）
　　

　　在用ajax进行提交时，如果验证错了，那么他会返回
　　
　　
　　如果是权限错了，他会返回
　　

　　但我想要的是
　　

　　那怎么办呢，其实很简单
　　我们只需要在　App\Exceptions\Handler 里面重写两个函数就可以了
　　
　　添加上这两个函数，然后里面怎么定义，就看你了
　　记得加上
　　

       use Illuminate\Validation\ValidationException; use Illuminate\Auth\Access\AuthorizationException;

最后附上这两个文件的代码
LoginPost

<?php namespace App\Http\Requests; use Illuminate\Foundation\Http\FormRequest; use Illuminate\Auth\AuthenticationException; class LoginPost extends FormRequest { /** * Determine if the user is authorized to make this request. * * @return bool */ public function authorize(){ if($this->input('account')=='[e-mail]'){ return false; } return true; } protected function failedAuthorization() { throw new AuthenticationException('该帐号已被拉黑'); } /** * Get the validation rules that apply to the request. * * @return array */ public function rules(){ return [ 'account'=>[ 'required', 'regex:/^1[34578][0-9]\d{4,8}|(\w)+(\.\w+)*@(\w)+((\.\w+)+)|[0-9a-zA-Z_]+$/',//验证为手机号，邮箱，或帐号 ], 'password'=>'required|between:6,18',//验证密码 ]; } public function messages(){ return [ 'account.required' => '帐号不能为空', 'account.regex' => '帐号不合法', 'password.required' => '密码不能为空', 'password.between' => '密码错误', ]; } 

Handler

<?php namespace App\Exceptions; use Exception; use Illuminate\Foundation\Exceptions\Handler as ExceptionHandler; use Illuminate\Validation\ValidationException; use Illuminate\Auth\AuthenticationException; class Handler extends ExceptionHandler { /** * A list of the exception types that are not reported. * * @var array */ protected $dontReport = [ // ]; /** * A list of the inputs that are never flashed for validation exceptions. * * @var array */ protected $dontFlash = [ 'password', 'password_confirmation', ]; /** * Report or log an exception. * * This is a great spot to send exceptions to Sentry, Bugsnag, etc. * * @param \Exception $exception * @return void */ public function report(Exception $exception) { parent::report($exception); } /** * Render an exception into an HTTP response. * * @param \Illuminate\Http\Request $request * @param \Exception $exception * @return \Illuminate\Http\Response */ public function render($request, Exception $exception) { return parent::render($request, $exception); } protected function unauthenticated($request, AuthenticationException $exception) { if($request->expectsJson()){ $response=response()->json([ 'status'=>3, 'msg' => $exception->getMessage(), 'errors'=>[], ], 200); }else{ $response=redirect()->guest(route('login')); } return $response; } protected function invalidJson($request, ValidationException $exception) { return response()->json([ 'status'=>2, 'msg' => $exception->getMessage(), 'errors' => $exception->errors(), ], $exception->status); } }
