无法从 Youtube Data API V3 [Python] 获得所有评论 [英] Can't get all comments from Youtube Data API V3 [Python]

问题描述

我有一个 python 函数，它允许您从 youtube 视频中获取所有评论.因此我使用 youtube API v3 comments.list 方法.

I have a python function, which allows you to get all comments from a youtube video. Therefore I use the youtube API v3 comments.list method.

key = 'My Key'
textFormat = 'plainText'
part = 'snippet'
maxResult = '100'
order = 'relevance'
nextToken = ''
videoId = 'Ix9NXVIbm2A'

while(True):
        response = requests.get("https://www.googleapis.com/youtube/v3/commentThreads?&key="+key+"&part="+part+"&videoId="+idVideo +"&maxResults="+maxResult+"&order="+order+"&pageToken="+nextToken)

        data  = response.json() #kind - etag - ?nextPageToken

        if 'error' in data:
            print(data)
            break

        for item in data['items']:
            snippet = item["snippet"]
            toplevelcomment = snippet['topLevelComment']
            content = toplevelcomment['snippet']

            commentid = toplevelcomment['id']
            authorname = content['authorDisplayName']
            textOriginal = content['textOriginal']

                #lists
            commentids.append(commentid)
            authornames.append(authorname)
            textOriginals.append(textOriginal)


        if 'nextPageToken' in data:
            nextToken = data['nextPageToken']

        else:
            break

从 pageToken 到另一个都进展顺利.但是当它到达pageToken编号13时，API总是返回

all progress good from pageToken to another. But when it reaches the pageToken number 13, the API always returns

{
'error': 
 {
 'errors': 
  [
   {
    'domain': 'youtube.commentThread', 
    'reason': 'processingFailure', 
    'message': '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.', 
    'locationType': 'other', 
    'location': 'body'
   }
  ], 
 'code': 400, 
 'message': '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.'
 }
}

我使用的是有效的密钥并且 pageToken 也有效(由 API 返回)

I'm using a valid key and the pageToken is valid too (returned by the API)

有没有人有同样的问题，或者我做错了什么?

Does anyone have the same problems or am I doing something wrong?

推荐答案

出现此错误是因为您的 api 限制已用完.Youtube 不时更改 api 的限制.

This error come because your api limits is exhausted. Youtube change the limit of api time to time.

有时也会出现网络问题.一旦请求失败，您必须编写多次尝试的代码.

And sometimes network problem is also occur. You have to write code for multiple attempt when once request is fail.
