google-drive-api - 团队云端硬盘文件的 Google 云端硬盘 REST API 结果不完整

Question

问题

在团队云端硬盘备份系统的第一阶段，我首先需要扫描给定团队云端硬盘中的文件，以确定要复制哪些文件进行备份。

I (think?) have full permissions over the files & folders of the Team Drive, due to the credentials I use (set to Owner in the cloud console).

尽管如此，我的问题是，当我查询 REST API 查找给定团队云端硬盘的文件列表时，结果不符合 documentation 。返回的文件对象仅包含 5 个字段，分别是:

• 种类、名称、id、mimeType、teamDriveId

根据提供的文档，我应该会收到更多字段。

下面是我用来查询 API 和输出的代码。

简化来源

credentials = get_credentials() # retrieves and processes app credentials
drive = get_drive_api(credentials) # get the drive API v3 using httplib2 and discovery
query = drive.files().list(
    pageSize = 10,
    corpora = 'teamDrive',
    supportsTeamDriveItems = True,
    includeTeamDrives = True,
    teamDriveId = "..."
)
results = query.execute() # contact the REST API
files = results.get('files', [])
for file in files:
    print(file)

对于给定的团队云端硬盘，输出为

{
  'kind': 'drive#file',
  'id': '...',
  'name': 'filename',
  'mimeType': 'application/vnd.google-apps.document',
  'teamDriveId': '...'
}

这显然不是 docs 的预期输出.

关于我没有获得完整预期数据的原因有什么见解吗？

Answer 1

With Google Drive API v3 full resources are no longer returned by default. Use the fields query parameter to request specific fields to be returned. If left unspecified only a subset of commonly used fields are returned.

要获取资源的所有可用字段，您可以将 fields 设置为 *。

例如:

query = drive.files().list(
    pageSize = 10,
    corpora = 'teamDrive',
    supportsTeamDriveItems = True,
    includeTeamDrives = True,
    teamDriveId = "...",
    fields="*"  # or maybe "files(id,name,capabilities/canShare),nextPageToken"
)
