随机获取随机Http错误,同时尝试从预定义的视频获取YouTube API v3在python中的评论。案例:给出每个视频ID和评论列表,直到python抛出错误,并停止进程。如果我重新加载程序,它可能会停留在相同或另一个视频以及不同的评论中。从40 *到500以及随机的错误。 试图把代码放在尝试除了,没有帮助。除了记住上次报废的视频ID并手动重新加载程序外,还可以做其他任何事情吗? 代码:使用Youtube API时发生随机Http错误,通过Python获得评论

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.">

你有可能简单地达到v3 api每秒请求的限制吗? – Av4t4r

傻犯了错误。相反,在“例外” API使用的错误标识的

... 
except HttpError, err: 
... 

Urlib2一个用于

... 
except urllib2.HTTPError, err: 
... 

简单的解决方案只是忽略和重复,直到成功。但是,仍然不清楚为什么这些随机错误即将到来。睡眠没有帮助。
