在python中对Google api执行oauth2 headless

Google的youtube Analytics API仅基于Oauth2。 我正在使用以下测试脚本来查看是否可以访问:

import os
import google.oauth2.credentials
import google_auth_oauthlib.flow
from googleapiclient.discovery import build
from googleapiclient.errors import HttpError
from google_auth_oauthlib.flow import InstalledAppFlow

SCOPES = ['https://www.googleapis.com/auth/yt-analytics.readonly']

API_SERVICE_NAME = 'youtubeAnalytics'
API_VERSION = 'v2'
CLIENT_SECRETS_FILE = 'client_secret.json'
def get_service():
  flow = InstalledAppFlow.from_client_secrets_file(CLIENT_SECRETS_FILE,SCOPES)
  credentials = flow.run_console()
  return build(API_SERVICE_NAME,API_VERSION,credentials = credentials)

def execute_api_request(client_library_function,**kwargs):
  response = client_library_function(
    **kwargs
  ).execute()

  print(response)

if __name__ == '__main__':
  # Disable OAuthlib's HTTPs verification when running locally.
  # *DO NOT* leave this option enabled when running in production.
  os.environ['OAUTHLIB_INSECURE_TRANSPORT'] = '1'

  youtubeAnalytics = get_service()
  execute_api_request(
      youtubeAnalytics.reports().query,ids='channel==MINE',startDate='2017-01-01',endDate='2017-12-31',metrics='estimatedMinutesWatched,views,likes,subscribersGained',dimensions='day',sort='day'
  )

我的问题是该脚本要求我打开浏览器,设置链接,登录,然后获得令牌电缆。

有没有办法在“无头”模式下执行此操作? 我需要提取这些API进行机器到机器的传输。

谢谢!

执行一次,然后将credentials = flow.run_console()返回的凭据对象保存到数据库或文件中。它包含一个“刷新令牌”,可以在后续的api调用中使用它,这意味着您可以跳过flow.run_console步骤,而仅在credentials调用中使用保存的build(API_SERVICE_NAME,API_VERSION,credentials = credentials)
