隨機獲取隨機Http錯誤,同時嘗試從預定義的視頻獲取YouTube API v3在python中的評論。案例:給出每個視頻ID和評論列表,直到python拋出錯誤,並停止進程。如果我重新加載程序,它可能會停留在相同或另一個視頻以及不同的評論中。從40 *到500以及隨機的錯誤。 試圖把代碼放在嘗試除了,沒有幫助。除了記住上次報廢的視頻ID並手動重新加載程序外,還可以做其他任何事情嗎? 代碼:使用Youtube API時發生隨機Http錯誤,通過Python獲得評論

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.">

傻犯了錯誤。相反,在「例外」 API使用的錯誤標識的

... 
except HttpError, err: 
... 

Urlib2一個用於

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

簡單的解決方案只是忽略和重複,直到成功。但是,仍然不清楚爲什麼這些隨機錯誤即將到來。睡眠沒有幫助。
