如何通过Google API获取共享云端硬盘授权用户列表及相关API支持情况咨询

Hey there! Let's tackle your questions about fetching authorized user lists for shared Google Drives using Google APIs—here's a clear breakdown:

The most straightforward way is using the Drive API's permissions.list endpoint. Here's how to do it:

• First, ensure your app has the correct scopes: You'll need https://www.googleapis.com/auth/drive (full access) or drive.readonly (read-only access). If you're a Workspace domain admin, drive.readonly.metadata works too for just metadata retrieval.
• When calling the endpoint, specify the shared drive's ID as the fileId parameter. You can grab the drive ID from its web URL—it's the string in the folders/ path (e.g., https://drive.google.com/drive/u/0/folders/[YOUR_DRIVE_ID]).
• Critical parameter: Add supportsAllDrives=true to your request. The Drive API doesn't handle shared drives by default, so this flag is mandatory to access permission data for shared drives.

Here's a quick curl example to test:

curl "https://www.googleapis.com/drive/v3/files/[YOUR_DRIVE_ID]/permissions?supportsAllDrives=true&fields=*" \
  -H "Authorization: Bearer [YOUR_ACCESS_TOKEN]"

The response will include all users, groups, or service accounts with access to the shared drive, along with their permission type (e.g., user, group), role (e.g., owner, organizer, reader), and identifying details like email addresses.

To answer your second question directly: Yes, Google fully supports retrieving authorized user lists for specific shared drives, and the Drive API is the right tool for this job. The Admin SDK has limited utility here—it's designed for managing domain-wide users/groups, not directly querying permissions for individual shared drives. That said, if you're a Workspace admin, you can combine Admin SDK data with Drive API results to filter domain-specific users, but the core permission data comes from the Drive API.

A few extra tips:

• If the shared drive has a large number of permissions, the API will paginate results. Use the nextPageToken returned in the response to fetch subsequent pages.
• External users (outside your domain) who have access to the shared drive will also appear in the results, as long as your app has the necessary permissions to read this data.
• For Google Workspace users, make sure your domain admin has enabled third-party app access to shared drives in the Admin Console's API permissions settings.
