Question

我目前正在尝试编写Python脚本，以使用YouTube API来获取我的YouTube频道成员。我已经创建了一个OAuth客户端，并经过了必要的步骤来设置我的所有令牌（我认为）。当我使用此OAuth客户端获取我的频道的订阅列表和其他信息时，此OAuth客户端有效，但是当我尝试获取我的成员时，我收到403错误。我相信这是因为Members Documention指出我必须填写特定的form才能访问此API路由。我填写了我认为Google需要的所有信息。但是，我没有收到有关此批准状态的任何更新，也没有收到有关是否填写正确信息的指示。

是否有人对使用YouTube API来获取频道成员有任何经验，并且到目前为止我是否做得正确？如果我正确执行此操作，批准一个应用程序需要多长时间才能访问成员API路由？

对于代码，我只是使用Python Web Client Quickstart Guide。我也尝试过使用示波器，但没有成功...

  # When running locally, disable OAuthlib's HTTPs verification.

具体来说，这些是当前有效的部分（我所属的频道）和不可用的部分（我的频道成员）...

  # THIS WORKS
  # subs = youtube.subscriptions().list(
  #     part="snippet,contentDetails",
  #     mine=True
  # ).execute()

  # THIS DOESNT WORK
  subs = youtube.members().list(
      part="snippet",
      maxResults=50
  ).execute()
