YouTube 链接似乎过期了?我真的不知道，但我需要解决这个问题.这是我的代码:

It seems like YouTube links expire? I don't really know but I need to fix this issue. This is my code:

    class YTDLSource(discord.PCMVolumeTransformer):

            self.title = data['title']
            self.description = data['description']

            self.duration = data['duration']
            self.web_url = data['webpage_url']
            self.thumbnail = data['thumbnail']

        def __getitem__(self, item: str):
            return self.__getattribute__(item)

        @classmethod

                raw_data = await loop.run_in_executor(None, to_run)

                if 'entries' in raw_data:
                    # take first item from a playlist
                    if len(raw_data['entries']) == 1:
                        data = raw_data['entries'][0]
                    else:

我正在为机器人使用 discord.py 的重写分支.我不确定是否需要提供更多详细信息?请告诉我，我真的需要解决这个问题...

I'm using the rewrite branch of discord.py for the bot. I'm not sure if I need to provide more details? Please let me know, I really need to get this fixed...

推荐答案

其实这并不是你的代码的问题(很多人抱怨这个错误).

In fact it isn't really a problem with your code (and many people complain of this error).

这只是流式传输视频时可能出现的问题.如果您绝对想流式传输它，则必须接受这是一个潜在问题.请注意(几乎)每个音乐机器人如何为您想要收听的视频/音乐设置限制.

This is just a possible issue when streaming a video. If you absolutely want to stream it, you have to accept this as a potential issue. Note how (almost) every music bots set limitations for the video/music you want to listen to.

如果您需要确保不会遇到此问题，则必须完全下载音乐.(这也会使机器人在播放前加载更长的时间).

If you need to ensure you do not get this issue, you have to fully download the music. (Which will also make the bot loading longer before playing).
