python - Gmail API 用户模拟(Python)

Question

我正在尝试通过服务帐户访问 Gmail API，并模拟我公司 G Suite 域中的用户来更改他们的电子邮件设置。我按照 Google 文档页面上的说明进行操作 here ，但我根据该指南提出的代码不断给我一个 HTTP 400:错误请求错误。

这是我的代码，我在其中尝试检索标签以查看我是否可以成功模拟用户:

from __future__ import print_function
import httplib2
import os

from apiclient import discovery
from oauth2client import client
from oauth2client import tools
from oauth2client.file import Storage

try:
    import argparse
    flags = argparse.ArgumentParser(parents=[tools.argparser]).parse_args()
except ImportError:
    flags = None

def main():


    from oauth2client.service_account import ServiceAccountCredentials

    #scopes = ['https://mail.google.com/', 'https://www.googleapis.com/auth/gmail.labels','https://www.googleapis.com/auth/gmail.readonly','https://www.googleapis.com/auth/gmail.settings.basic ','https://www.googleapis.com/auth/gmail.settings.sharing']
    scopes = ['https://mail.google.com/']

    credentials = ServiceAccountCredentials.from_json_keyfile_name('/Users/bartoszanimucki/Downloads/service_secret.json', scopes)
    http = credentials.authorize(httplib2.Http())

    delegated_credentials = credentials.create_delegated('user@domain.com')
    http_auth = credentials.authorize(httplib2.Http())

    service = discovery.build('gmail', 'v1', http=http_auth)

    results = service.users().labels().list(userId='me').execute()

    print(results)

if __name__ == '__main__':
    main()

脚本在 execute() 方法处失败，出现 HTTP 400。有什么想法吗？

作为引用，这是我从 Python 得到的错误信息:

Traceback (most recent call last):
  File "sample.py", line 37, in <module>
    main()
  File "sample.py", line 32, in main
    results = service.users().labels().list(userId='bb@comcamenergy.com').execute()
  File "/Library/Python/2.7/site-packages/oauth2client/_helpers.py", line 133, in positional_wrapper
    return wrapped(*args, **kwargs)
  File "/Library/Python/2.7/site-packages/googleapiclient/http.py", line 840, in execute
    raise HttpError(resp, content, uri=self.uri)
googleapiclient.errors.HttpError: <HttpError 400 when requesting https://www.googleapis.com/gmail/v1/users/bb%40comcamenergy.com/labels?alt=json returned "Bad Request">

我想通了!我试图使用链接到服务帐户的 Credentials 对象，而不是 delegated_credentials。它通过更改行来修复:

http_auth = credentials.authorize(httplib2.Http())

到

http_auth = delegated_credentials.authorize(httplib2.Http())

谢谢指教!注意细节是值得的。
