获取youtube实时聊天评论和实时流“找不到您尝试检索的实时聊天[404]”和“未选择过滤器[400]”

Question

我需要使用Youtube API从我的youtube帐户中获取实时流列表，并从我的LiveStream LiveChat中获取所有评论。

该令牌很好（因为我多次删除了该令牌，并且在我再次启动该应用并获得许可后再次自动下载了该令牌）。 授予，删除和再次授予访问权限（我尝试过...）（我在这里可以通过“ youtube”权限https://myaccount.google.com/permissions?pli=1看到它） 在Google提示再次询问是否允许我访问此应用后，令牌已删除并自动再次自动添加。
