python - pafy.get_playlist() 不适用于下载

Question

我正在开发一个播放列表下载器应用程序，但我在 def playlist_Download(self): with code 中遇到了问题

#playlist = pafy.get_playlist(playlist_url)

&

#playlist2 = pafy.get_playlist2(playlist_url

当我单击应用程序中的下载单击时，我使用播放列表功能收到此消息：

urllib.error.HTTPError：HTTP 错误 404：未找到

并使用 playlist2 函数发送此消息：

pafy.util.GdataError: Youtube 错误 403: The request cannot be completed because you have exceeded your quota。有谁能帮助我吗？
