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），然后简单地检索我所有视频的列表，公共和私人。

除了完全自动化的部分，我已经能够成功地完成这项工作。我使用了各种来源的代码，当我在命令行上运行它时，它为我提供了一个可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&redirect3Auriet%3Auth%Aurn3A ％3Aoob＆范围= HTTPS％3A％2F％2Fwww.googleapis.com％2Fauth％2Fyoutube.readonly＆状态= zNVvgEyO47nmacvdEEAhDsQipY194k＆提示=同意＆ACCESS_TYPE =离线＆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（从 CMD 逐字复制 URL，访问以获取令牌，以及复制和再次粘贴令牌）？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？如果是这样，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。

该Credentials实例credentials = flow.run_console()具有刷新令牌的内置功能。如果需要，它将在执行请求时刷新令牌。

因此，您可以将credentials对象保存到pickle中，并在需要时读取它

对 Google python 示例代码进行一些修改：

def get_authenticated_service():
    if os.path.exists(CREDENTIALS_PICKLE_FILE):
        with open(CREDENTIALS_PICKLE_FILE, 'rb') as f:
            credentials = pickle.load(f)
    else:
        flow = InstalledAppFlow.from_client_secrets_file(CLIENT_SECRETS_FILE, SCOPES)
        credentials = flow.run_console()
        with open(CREDENTIALS_PICKLE_FILE, 'wb') as f:
            pickle.dump(credentials, f)
    return build(API_SERVICE_NAME, API_VERSION, credentials = credentials)
