尝试通过Python中的服务帐户使用 AdminSettings API 检索域用户数“GetCurrentNumberOfUsers()” 。启用了广泛的授权和范围，但出现错误。我已将服务帐户用于日历 API、目录 API、电子邮件设置 API，但不适用于 AdminSettings。在以下位置尝试了示例代码：github.com/Khan/gdata-python-client/blob/master/samples/apps/adminsettings_example.py但在为管理员帐户使用正确凭据时出现“需要授权”错误：API Client Acccess 

from oauth2client.client import SignedJwtAssertionCredentials
import gdata.gauth
import gdata.apps.service
import gdata.apps.adminsettings.service

SERVICE_ACCOUNT_EMAIL = "XXXXXXXXXXXXX-ebirq08jvhldahbb482u8a1otu9n3l8p.apps.googleusercontent.com"
SERVICE_ACCOUNT_PKCS12_FILE_PATH = 'gapi_admin/privatekey.p12'
f = file(SERVICE_ACCOUNT_PKCS12_FILE_PATH, 'rb')
key = f.read()
f.close()
credentials = SignedJwtAssertionCredentials(SERVICE_ACCOUNT_EMAIL, key, scope='https://apps-apis.google.com/a/feeds/domain/', sub='admin@xxxtestmail.edu')
auth2token = gdata.gauth.OAuth2TokenFromCredentials(credentials)
service = gdata.apps.adminsettings.service.AdminSettingsService(source="testApp", domain='xxxtestmail.edu')
service = auth2token.authorize(service)

print service.GetCurrentNumberOfUsers()

#output
#TypeError: new_request() takes exactly 1 non-keyword argument (2 given)

在 OAuth2 Playground 中工作正常，查看Screenshot。

旧的 GData Python 库服务对象实际上并不支持您需要使用的 OAuth 2.0。但是，您可以在那里破解访问令牌。尝试类似：

credentials = SignedJwtAssertionCredentials(SERVICE_ACCOUNT_EMAIL, key, scope='https://apps-apis.google.com/a/feeds/domain/', sub='admin@xxxtestmail.edu')
credentials.refresh(httplib2.Http())
service = gdata.apps.adminsettings.service.AdminSettingsService(source="testApp", domain='xxxtestmail.edu')
service.additional_headers[u'Authorization'] = u'Bearer {0}'.format(credentials.access_token)

print service.GetCurrentNumberOfUsers()
