【问题描述】:
在尝试使用 Python 上的 YouTube API v3 从预定义视频中获取 cmets 时随机获取随机 Http 错误。案例:为每个视频 id 和 cmets 下载列表,直到 python 抛出错误,进程停止。如果我重新加载程序,它可能会卡在同一视频或另一个视频以及不同的 cmets 上。误差范围从 40* 到 500 以及随机基础。 试图将代码放入尝试中,但没有帮助。除了记住上次报废的视频 ID 和手动重新加载程序之外,我还能做什么? 代码:

请同时发布一些带有相关错误文本的错误示例。
-
您是否可能只是达到了 v3 api 的每秒请求数限制?
-
您好,感谢您的评论,现在我只是随机收到“http 400 错误”,这是我以前没有遇到的,也许明天会出现一些不同的情况。跨度>
