Question

我有一个烧瓶应用程序从谷歌表中获取一些数据。当我在本地计算机上运行烧瓶应用程序时，最初它通过0auth2身份验证创建凭据并将其存储在本地。在成功完成flask本地应用程序之后，我在docker容器中创建了相同的应用程序。

场景1
容器具有在以下位置复制/添加的凭据容器创建的时间。在这种情况下，烧瓶应用程序工作没有任何问题

场景2
容器当前没有凭据文件。因此，它必须通过调用get_credentials()函数来生成文件。此时，Web浏览器停止/继续等待来自服务器的响应（浏览器在加载阶段）

场景2是问题。希望有人可以帮助我..
我正在关注这个documentation。
