Old question and all that, but the link in the other answer is dead.

我的研究表明，我需要授予服务帐户电子邮件地址访问 Google 驱动器上目录的权限，但我终生不知道如何做到这一点.

My research suggests that I need to give the service account email address access to a directory on Google drive, but I can't find out for the life of me how to do that.

获得电子邮件地址后，您可以通过 Google Drive UI 执行此操作:

You can do this through the Google Drive UI after you have the email address:

1. 从 https://console.developers.google.com/获取服务帐户的电子邮件地址api/凭据
2. 在 Google 云端硬盘中，导航到您要共享的文件夹
3. 右键单击文件夹
4. 点击分享"
5. 输入您在第 1 步中获得的电子邮件地址，然后点击完成".
