python-3.x - Youtube Data API v.3 - 全自动 oAuth 流程(Python)？

Question

我一直在探索 YouTube 数据 API。我的项目的前提很简单:使用 API，进行身份验证(是的，我有帐户的凭据)，然后简单地检索我的所有视频列表，公共(public)和私有(private)。

我已经能够成功地完成这个，除了完全自动化的部分。我使用了各种来源的代码，当我在命令行上运行它时，它为我提供了一个在浏览器中使用的链接，以便进行授权。

它看起来像这样:

请访问此 URL 以授权此应用程序:https://accounts.google.com/o/oauth2/auth?response_type=code&client_id=7932902759886-cb8ai84grcqshe24nn459ka46uh45ssj.apps.googleusercontent.com&redirect_uri=urn%3Aietf%3Awg%3Aoauth%3A2.0%3Aoob&scope=https%3A%2F%2Fwww.googleapis.com%2Fauth%2Fyoutube.readonly&state=zNVvgEyO47nmacvdEEAhDsQipY194k&prompt=consent&access_type=offline&code_challenge=aF7uTCghjwgwjg49o3fgiIU-_ryK19rDeX4l1uzr37w&code_challenge_method=S256
输入授权码:

……

这是我的python代码片段:

import google_auth_oauthlib.flow
import googleapiclient.discovery
import googleapiclient.errors
...
...

# Get credentials and create an API client
flow = google_auth_oauthlib.flow.InstalledAppFlow.from_client_secrets_file(
    client_secrets_file, scopes)
credentials = flow.run_console()
youtube = googleapiclient.discovery.build(
    api_service_name, api_version, credentials=credentials)
## MAKE youtube SEARCH REQUEST
last_date = '2018-10-01T00:00:00Z'
request = youtube.search().list(
    part="snippet",
    forMine=True,
    maxResults=50,
    order="date",
    type="video"
)
all_items = []
response = request.execute()

我的问题如下: 是否可以以编程方式执行授权，以便应用程序可以独立运行而不必等待此用户操作 (要从 CMD 复制 URL，访问以获取 token ，然后再次复制并粘贴 token )？我想安排这个，因此希望它在没有人工干预的情况下运行和验证。这可能吗？如果是， 有人可以指点我一些工作示例和/或其他资源来帮助我到达那里吗？太感谢了。
