Authentication 调用未定义的方法\Http\JsonResponse:：validate（）

我正在使用带有

Laravel 5.3

它在web上运行良好，但我在postman中看到以下例外

FatalErrorException in RegistersUsers.php line 31:
Call to undefined method Illuminate\Http\JsonResponse::validate()

Auth\RegisterController

   protected function validator(array $data)
    {
        if(Request::wantsJson()) {
            $rules  =   array(
            'first_name'    =>  'required',
            'last_name'     =>  'required',
            'email'         =>  'required',
            'password'      =>  'required',
            'phone_number'  =>  'required',

            );
            $validator  =   Validator::make($data, $rules);
            if($validator->fails()) {
                return response()->json($validator->messages());

            }
        } else {
            return Validator::make($data, [
                'name' => 'required|max:255',
                'email' => 'required|email|max:255|unique:users',
                'password' => 'required|min:6|confirmed',
            ]);

        }

    }

错误的完整堆栈跟踪为

验证器方法应该返回一个验证器实例。在Request:：wantsJson（）的情况下，返回一个JsonResponse（在失败时）或什么都不返回（在成功时）。您可能应该返回$validator。

有人能举例说明这个答案吗？谢谢所以当我返回$validator时。。。我在邮递员身上发现以下错误…----“无法得到任何回应”有人能用一个例子来解释这个答案吗？谢谢所以当我返回$validator时。。。我在邮递员身上发现以下错误…----“无法获得任何响应”
