Youtube Data API 不断请求授权

Question

我正在尝试制作一个简单的 python 程序，它使用 Youtube Data API 根据 Youtube 搜索查询检索结果。

我已经创建了我的 OAuth 凭据并拥有一个 client_secrets JSON。每次我运行我的 python 程序时，它都会要求我获取授权密钥，以便我可以进行查询。我必须打开 chrome 并访问 API 提供给我的 URL，然后登录我的 Google 帐户并粘贴密钥。

有人可以演示如何使这个过程自动化吗？我在网上和 stackoverflow 上读到我需要一个刷新令牌，或者以某种方式存储一个，这样它就不会每次都提示我授权。

我的代码（复制自https://developers.google.com/youtube/v3/docs/search/list）：

# The CLIENT_SECRETS_FILE variable specifies the name of a file that contains
# the OAuth 2.0 information for this application, including its client_id and
# client_secret.
CLIENT_SECRETS_FILE = "client_secret.json"

# This OAuth 2.0 access scope allows for full read/write access to the
# authenticated user's account and requires requests to use an SSL connection.
SCOPES = ['https://www.googleapis.com/auth/youtube.force-ssl']

API_VERSION = 'v3'

def get_authenticated_service():
  flow = InstalledAppFlow.from_client_secrets_file(CLIENT_SECRETS_FILE, SCOPES)
  credentials = flow.run_console()
  return build(API_SERVICE_NAME, API_VERSION, credentials = credentials)

        # "for pa in range ..." loop, we will be setting a property in the

        ref[key] = {}

Answer 1

我也遇到了同样的问题。在搜索“YouTube Data Api v3”文档后，我发现了这个：

如果您使用的是已安装的应用流程，则此示例代码中不存储授权凭据，因此后续执行将提示重新授权。

所以我猜你应该改用“Web Server App”流程。没有办法解决这个问题。
