我想通过后台cron作业将谷歌分析中的数据拉入自己的数据库，而无需用户每次都进行身份验证。
正如我之前所问的，我知道如何通过用户交互获得Google Analytics OAuth访问令牌。使用OAuth是行不通的，因为它需要用户交互。根据Google Analytics API，参考OAuth和访问令牌可以用于在每次会话的基础上访问页面的统计数据。然而，我正在寻找一种持久的方法来在后台服务中实现这一点。
如何在没有用户身份验证的情况下访问google analytics或获得无过期访问令牌？
假设有问题的帐户是您自己的，您可以为我们提供服务帐户。确保您在帐户级别为服务帐户的电子邮件地址提供了对谷歌分析帐户的读取权限，它将能够读取您的数据。

代码从教程谷歌服务帐户与PHP
如果这不是你的帐户，那么你可以使用普通的Oauth2方法，要求用户对你进行一次身份验证，然后使用刷新令牌，你就可以访问数据。使用上一个问题中的代码。
