java - 设置 GOOGLE_APPLICATION_CREDENTIALS 仍然无法启用对 Google Storage 的访问

Question

This answer展示如何使用 Java 中的服务帐户访问 Google Cloud Storage。
使用硬编码服务帐户凭据，我可以访问 GCS。但是，使用 GOOGLE_APPLICATION_CREDENTIALS 或运行 gcloud auth application-default login，我无法访问 GCS 并收到 GoogleJsonResponseException: 401 Unauthorized。
我的操作系统是Win7_64x。

如何检查我哪里错了？

Answer 1

哦，亲爱的。我犯了一个错误。

我在变量值文本框中引用了变量值。
不需要使用引号将该字符串括起来。

不正确:“/path/to/jsonfile.json”
正确:/path/to/jsonfile.json
