以管理员身份访问所有用户驱动器

Question

我正在构建一个使用 Microsoft Graph 的本机应用程序。我想通过管理员帐户读取组织中所有用户的 OneDrive 中的所有文件。

我正在使用 (Azure AD 2.0) OAUTH 授权工作流来获取授权码。之后我获得了访问令牌和刷新令牌。

然而，当我尝试访问任何用户的驱动器时：

graphClient.Drives["amit@csys.onmicrosoft.com"].Root.Request().GetAsync();
// where graphClient is instance of GraphServiceClient

我得到：

generalException

Message: Unexpected exception returned from the service.

调用堆栈：

管理员可以访问所有其他用户的驱动器文件吗？

注意：当我以管理员身份登录时，我可以访问管理员的 OneDrive 帐户。

Answer 1

您的示例中的驱动器索引器需要一个 driveId，而不是 upn。

假设您的权限设置正确，并且您拥有有效的访问令牌，你会做这样的事情。

// Access the users in the org.
var users = await graphClient.Users.Request().GetAsync();

// Get the drives for a user.
var drives = await graphClient.Users[users[0].Id].Drives.Request().GetAsync();

// Get the specific drive metadata for a user
var drive = await graphClient.Drives[drives[0].Id].Request().GetASync();

以管理员身份访问所有用户驱动器

Access all user drives as Admin
