Codeigniter中的Google Analytics（分析）广告系列数据

Question

我正在尝试在codeigniter的Google Analytics（分析）帐户中列出广告系列数据。我遵循了Google链接：

Analytics reporting API v4; PHP Quickstart

我在项目中完全使用了上述URL中的代码，但是我找不到用于获取广告系列数据的代码。请帮助我获取从Google Analytics（分析）中获取广告系列数据的方式。

谢谢

这是我的代码-

        pr($response);
        $this->printResults($response);
    }

        $analytics = new Google_Service_AnalyticsReporting($client);
