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）

最后附上这两个文件的代码 
LoginPost

<?phpnamespace 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($this->input('account')=='aaa@abc.com'){return false;}return true;}protected function failedAuthorization(){throw new AuthenticationException('该帐号已被拉黑');}/*** Get the validation rules that apply to the request.** @return array*/public function rules(){return ['account'=>['required','regex:/^1[34578][0-9]\d{4,8}|(\w)+(\.\w+)*@(\w)+((\.\w+)+)|[0-9a-zA-Z_]+$/',//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',];}}
