我第一次尝试使用Google CloudStorage。
我只是按照文章https://developers.google.com/appengine/docs/java/googlestorage/
中给出的步骤进行操作我已按照以下步骤操作。
我在xyz.com域名中创建了一个应用程序，我的应用程序的服务帐户名称为“myapp@appspot.gserviceaccount.com”。
然后我转到Google API控制台上的“团队”标签，并尝试将我的应用程序的服务帐户名称添加到我已激活Google云端存储的项目中。
它已成功添加，但状态是等待我如何将状态更改为活动。当我运行我的项目时我得到了
