調用未定義的方法照亮\ HTTP \ JsonResponse ::的validate（）

Question

我實現一個登記表，並與Laravel 5.3

它工作正常的網絡使用發送郵差POST請求，但我看到郵遞員以下異常

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

在錯誤的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', 
      ]); 

     } 

    } 

完整的堆棧跟蹤我的驗證方法是

驗證器方法應該返回一個Validator實例。在Request :: wantsJson（）的情況下，你返回一個JsonResponse（失敗），或者根本沒有（成功）。您應該可以返回$ validator。
