如何从“google drive api”文件列表中查看路径

Question

我已经关注https://developers.google.com/drive/api/v2/reference/files/list，成功了！我明白了。但不是我的“驱动器”。我收到一条警告“您需要在此处获得访问权限。那么我该如何解决上述错误呢？

我创建了一个新项目、服务帐号密钥和 OAuth 2.0 客户端 ID。但很糟糕，它没有正确链接到我的“google drive”帐户

这是我的全部代码

您需要记住的是，服务帐户不是您。服务帐户是一个虚拟用户。它有自己的谷歌驱动器帐户。当您将文件上传到服务帐户驱动器帐户时，它们只能由该帐户访问，因为它是它的所有者。

共享驱动器

如果您希望它能够访问您的个人云端硬盘帐户中的文件，您需要通过与服务帐户电子邮件地址共享文件来授予其访问权限。这就是预先批准服务帐户的方式。

获取路径

至于获取文件的路径，没有简单的方法可以做到这一点，您需要通过获取文件，然后获取其父级，然后获取更多父级，直到您到达顶部和以这种方式构建它。
