在python上使用youtubeapiv3从预定义视频中获取评论时,随机获取Http错误。案例:给定的视频ID和注释列表为每一个下载,直到python抛出错误,进程停止。如果我重新加载程序,它可能会停留在同一个或另一个视频,以及不同的评论。随机误差范围为40*到500。 尝试在try中输入代码,但没有帮助。除了记住上次废弃的视频id和手动重新加载程序,我还能做什么? 代码:

编辑:-------------------------- 很少出错
HttpError: <HttpError 400 when requesting https://www.googleapis.com/youtube/v3/commentThreads?pageToken=ChYQpqWd6pfYzgIYyISxrpfYzgIgACgcEhQIABDIhLGul9jOAhiQgZuP9IfOAhgCIO4VKJHr35vwuKix-gE%3D&part=snippet&key=AIzaSyBzExhLoWbeHU1iKHZuaYV7IBPJNiyaDkE&alt=json&videoId=D0uEXoL04OM&maxResults=100 returned "The API server failed to successfully process the request. While this can be a transient error, it usually indicates that the requests input is invalid. Check the structure of the <code>commentThread</code> resource in the request body to ensure that it is valid.">
犯了个愚蠢的错误。“exception”中使用了错误标识符而不是API
使用了Urlib2 one
简单的解决办法就是忽略和重复,直到成功。然而,仍然不清楚为什么会出现这些随机错误。睡觉没用。你知道吗
