我正在创建一个 MacOS 应用程序，该应用程序在给定的 Google Team Drive/文件夹中创建自定义文件夹层次结构。每次我运行该应用程序时，它都会打开一个浏览器并要求用户登录并允许该应用程序访问。接受后，应用程序会创建文件夹并按预期工作。但是，它每次都会这样做，我很难找出如何保存“用户的同意”，以便他们只需要允许一次同意，即他们第一次运行应用程序时。我尝试了许多不同的选择，但我一无所获，所以我非常感谢任何帮助。

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

SCOPES = ['https://www.googleapis.com/auth/drive']
API_SERVICE_NAME = 'drive'
API_VERSION = 'v3'

def get_authenticated_service():
    client_secrets = args["secrets"] #client_secrets.json file passed as "secrets" argument

    flow = InstalledAppFlow.from_client_secrets_file(client_secrets, SCOPES)

    credentials = flow.run_local_server(host='localhost',
                                    port=8080,
                                    authorization_prompt_message='Please visit this URL: {url}',
                                    success_message='The auth flow is complete; you may close this window.',
                                    open_browser=True)

    return build(API_SERVICE_NAME, API_VERSION, credentials = credentials)

if __name__ == '__main__':
    service = get_authenticated_service()
    name = format_client_name()
    create_folders(service, name)

我在这里尝试使用 Google API 客户端库（https://developers.google.com/api-client-library/python/guide/aaa_oauth），它显示存储，但是它没有任何与谷歌相关的说明。 oauth，因为您不能将 oauth2client 存储与 google.oauth 一起使用。我觉得这很简单，但我碰壁了。

您可以使用oauth2client.file.Storage将凭据存储在credentials.json文件中以供将来检索。该函数在运行身份验证流程之前检查本地存储的有效凭据。

我在下面的 repo 中附上了一个示例：
