google.oauth2.credentials.Credentials使用有效令牌失败

我正在尝试通过Python 3.6列出我的YouTube频道，因为（这很重要）已有访问令牌和一些有效的API密钥。它与curl配合良好，并返回有效的JSON响应：

curl 'https://www.googleapis.com/youtube/v3/channels?part=snippet&mine=true&key=API_KEY' \
-H 'Accept: application/json' \
-H 'Authorization: Bearer ACCESS_TOKEN'

响应：

{
    "kind": "youtube#channelListResponse",
    "etag": "\"xxxxxxxxx\"",
    "pageInfo": {...},
    "items": [...]
}

如果删除授权标头，则会出现预期的错误：

{
    "error": {
        "errors": [
            {
                "domain": "youtube.parameter",
                "reason": "authorizationRequired",
                "message": "The request uses the <code>mine</code> parameter but is not properly authorized.",
                "locationType": "parameter",
                "location": "mine"
            }
        ],
        "code": 401,
        "message": "The request uses the <code>mine</code> parameter but is not properly authorized."
    }
}

现在，我尝试对Google Python库执行相同的操作（因为我需要它来进行更复杂的操作和代码控制），但是它不起作用。我收到与未传递任何访问令牌相同的错误。有什么想法我做错了吗？这是我的Python代码（请注意，访问令牌已赋予代码，我必须原样使用）：

import argparse
import google.oauth2.credentials
from googleapiclient.discovery import build
from googleapiclient.errors import HttpError

def get_authenticated_service(options):
  creds = google.oauth2.credentials.Credentials(options.access_token)
  return build('youtube', 'v3', credentials=creds, developerKey=options.api_key)

def list_channels(youtube, options):
  request = youtube.channels().list(part="snippet", mine=True)
  response = request.execute()
  print(response)

if __name__ == '__main__':
  parser = argparse.ArgumentParser()
  parser.add_argument('--api_key', required=True)
  parser.add_argument('--access_token', required=True)
  args = parser.parse_args()
  youtube = get_authenticated_service(args)
  try:
    list_channels(youtube, args)
  except HttpError as e:
    print('An HTTP error {0} occurred:\n{1}'.format(e.resp.status, e.content))

我这样运行：

python3 test.py --api_key MY_API_KEY --access_token MY_ACCESS_TOKEN
