 方法1

namespace app\lib;class Response extends \yii\web\Response{    public function alert($message, $code = 1, $data = null){        $this->format = self::FORMAT_JSON;        $this->data = [            ‘message‘ => $message,            ‘code‘ => $code,            ‘data‘ => $data        ]        return $this;    }}//修改response組件的配置後，就可以這樣調用了嘛return Yii::$app->response->alert(‘餘額不足‘);

 方法2

‘response‘ => [    ‘on beforeSend‘ => function($event){        $response = $event->sender;        if(                $response->format != \yii\web\Response::FORMAT_JSON //沒設定format為JSON            &&    is_array($response->data) //數組        ){            $data = $response->data;            $response->data = [                ‘message‘ => $data[0],                ‘code‘ => isset($data[1]) ? $data[1] : 0,                ‘data‘ => isset($data[2]) ? $data[2] : ‘‘,            ];            $response->format = \yii\web\Response::FORMAT_JSON;        }    }],//於是action可以這樣用：return [‘餘額不足‘];return [‘操作成功！‘, 0];return [‘搜尋結果‘, 0, $dataList];return $this->render(‘xxx‘); //此時返回的是string，beforeSend裡有is_array的判斷，所以不會影響模板的輸出
