Google服务帐户无法模拟GSuite用户

python

from google.oauth2 import service_account
import googleapiclient.discovery

SCOPES = ['https://www.googleapis.com/auth/calendar']
SERVICE_ACCOUNT_FILE = 'GOOGLE_SECRET.json'

credentials = service_account.Credentials.from_service_account_file(
        SERVICE_ACCOUNT_FILE, scopes=SCOPES)

delegated_credentials = credentials.with_subject('address@example.com')

google_calendar = googleapiclient.discovery.build('calendar', 'v3', credentials=delegated_credentials)

events = google_calendar.events().list(
    calendarId='address@example.com',
    maxResults=10
).execute()

上述代码的结果是:

google.auth.exceptions.RefreshError: ('unauthorized_client: Client is unauthorized to retrieve access tokens using this method.', '{\n  "error" : "unauthorized_client",\n  "error_description" : "Client is unauthorized to retrieve access tokens using this method."\n}')

Domain-wide delegation开启。服务帐户客户ID已在GSuite中使用适当的范围进行了授权。

该服务帐户可用于普通凭据。它仅不适用于委托凭证。

我在我们的域中尝试了不同的API(作用域)和不同的用户。

我有一个同事尝试从头开始编写示例,他得到了同样的东西。

我认为您的问题是,在调用Calendar
API
之前,您没有对凭据进行授权,但是我在自己的实现中使用了一些区别

  • 使用以下导入语句

    from oauth2client.service_account import ServiceAccountCredentials
    

    from apiclient import discovery

  • 使用from_json_keyfile_name方法

  • 授权凭证,并http在构建服务时将其作为参数传递

尝试对您的代码进行此修改:

from apiclient import discovery
from oauth2client.service_account import ServiceAccountCredentials
import httplib2

SCOPES = ['https://www.googleapis.com/auth/calendar']
SERVICE_ACCOUNT_FILE = 'GOOGLE_SECRET.json'

credentials = ServiceAccountCredentials.from_json_keyfile_name(
        SERVICE_ACCOUNT_FILE, scopes=SCOPES)

# Use the create_delegated() method and authorize the delegated credentials
delegated_credentials = credentials.create_delegated('address@example.com')  
delegated_http = delegated_credentials.authorize(httplib2.Http())
google_calendar = discovery.build('calendar', 'v3', http=delegated_http)

events = google_calendar.events().list(
    calendarId='address@example.com',
    maxResults=10
).execute()

我也建议calendarId='primary'您在API调用中进行设置,以便始终返回当前为其委派了凭据的用户的主日历。

有关使用进行身份验证的更多信息,ServiceAccountCredentials请参见以下链接:http
