Lumen with Dingo API Helpers返回錯誤的狀態代碼

Question

我正在使用Lumen和Dingo API構建API。我的註冊功能會檢查指定的電子郵件是否已經存在。

如果電子郵件已存在於數據庫中，則使用Dingo API助手返回錯誤響應。

Dingo\Api\Routing\Helpers 

isEmailTaken功能：

private function isEmailtaken($email) { 
    $userExists = User::where('email', $email)->count(); 
    if($userExists) { 
     $return['error'] = true; 
     $return['message'] = "It appears you already have an account with us."; 
     return $return; 
    } else { 
     $return['error'] = false; 
     return $return; 
    } 
} 

註冊函數調用函數，並返回一個錯誤：

$validateEmail = $this->isEmailtaken($email); 
    if ($validateEmail['error'] == true) { 
     return $this->response->errorBadRequest($validateEmail['message']); 
    } 

它輸出與JSON響應正確的錯誤代碼正確的錯誤消息：

"{"message":"It appears you already have an account with us.","status_code":400}" 

然而，在頭產生的響應狀態正常和代碼是200

Answer 1

STATUS_CODE 400 bad request當請求數據不低於代碼幫助有效

返回定製STATUS_CODE

響應將返回

use Illuminate\Http\Response; 


return response()->json(['message' => 'It appears you already have an account with us.'])->setStatusCode(400); 

另外短路辦法從laravel驗證驗證獨特EMAILID像下面

$rules = array(

      'email'=>'required|email|unique:user', 
      ); 

    $validator = Validator::make($request->all(), $rules); 

    if (!$validator->passes()) { 
     return response()->json([ 'message' => $validator->messages()])->setStatusCode(400); 

}
