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 数据 API 来检索基于 Youtube 搜索查询的结果。

我已经创建了我的 OAuth 凭据并且有一个 client_secrets JSON。每次我运行我的 python 程序它总是要求我获得授权密钥以便我可以进行查询。我必须打开 chrome 并前往 API 给我的 URL 并登录到我的 Google 帐户并粘贴密钥。

有人可以演示我如何让这个过程自动化吗？我在网上和 Whosebug 上读到我需要一个刷新令牌，或者以某种方式存储一个，这样它就不会提示我每次都授权。

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

Answer 1

我刚运行遇到了同样的问题。在搜索 "YouTube Data Api v3" 文档后，我发现了这个：

If you are using the installed app flow, authorization credentials are not stored in this sample code, so subsequent executions will prompt for reauthorization.

所以我想您应该改用 "Web Server App" 流程。没有办法解决这个问题。

Answer 2

试试这个

def get_authenticated_service():
    try:
        credentials = google.oauth2.credentials.Credentials.from_authorized_user_file(CLIENT_SECRETS_FILE)
    except ValueError as e: # first run with new secret.json
        flow = InstalledAppFlow.from_client_secrets_file(CLIENT_SECRETS_FILE, SCOPES)
        credentials = flow.run_console()
        with open(CLIENT_SECRETS_FILE, 'w') as file:
            file.write(credentials.to_json())
    return build(API_SERVICE_NAME, API_VERSION, credentials=credentials)
