java - ApiProxy$ApplicationException : ApplicationError: 8 after created the API Access in google Cloud Storage

Question

我创建了一个“可以编辑”的服务帐户名称来访问谷歌云存储。我使用了 Complete sample Application 中提供的示例应用程序用于 java 并部署在 App Engine 中。当在浏览器中调用 servlet 时出现这样的错误，

Uncaught exception from servlet
java.io.IOException

谁能建议我解决这个问题。

提前致谢!

您是否按照文档 [1] -> 5 中的说明授予了访问权限。为您的存储桶或对象授予权限。)?

您使用哪个版本的 SDK？可能是旧的 SDK 版本导致了这个异常。
