我有一个网站,我希望向所有访问者显示我的Google Analytics帐户中的一些数据(来自不同国家/地区的独特网页浏览量).就我而言,可以使用OAuth 2.0和Google AnalyticsAPI执行此操作.我希望身份验证能够实现自动化,以便访问我网站的任何人都可以查看此数据,而不仅仅是可以登录我的Google Analytics帐户的用户.

我做了什么

>使用GOOGLE DeveloPErs Console制作项目.
>将Analytics API更改为ON.
>创建了一个服务帐户.
>为服务器和浏览器应用程序生成的API密钥(不知道确切地使用哪个和哪里使用).
>下载用于PHP的Google Api客户端库.
>上传了我创建服务帐户时下载的.p12密钥,将其上传到我的网站并链接到google-api-PHP-client-master / examples / service-account.PHP.
>在google-api-PHP-client-master / examples / service-account.PHP中声明了我的服务帐户客户端ID.

问题

>在google-api-PHP-client-master / examples / service-account.PHP中有这段代码,我不太明白：

$service_account_name =”;

我应该在这里宣布什么？

>当我完成上述所有操作并在我的网站上加载google-api-PHP-client-master / examples / service-account.PHP页面时,我收到以下两个错误：

我做错了什么？
