Как получить комментарии к видео youtube

Question

Я пытаюсь получить все комментарии к видео с YouTube, используя следующий подход, но я не могу получить все комментарии, связанные с видео, только некоторые из комментариев будут получены. я попытался сделать это, но ничего не помогло, может кто-нибудь объяснить, как получить все комментарии, связанные с видео с YouTube.

//url :- "https://www.googleapis.com/auth/youtube.force-ssl" 

public void ReadAllComments(String videoId){ 
    try { 

     CommentThreadListResponse videoCommentsListResponse = youtube.commentThreads() 
       .list("snippet").setVideoId(videoId).setTextFormat("plainText").execute(); 

     List<CommentThread> videoComments = videoCommentsListResponse.getItems(); 

      for (CommentThread videoComment : videoComments) {    
       CommentSnippet snippet = videoComment.getSnippet().getTopLevelComment().getSnippet(); 
       System.out.println(" - Author: " + snippet.getAuthorDisplayName()); 
       System.out.println(" - Comment: " + snippet.getTextDisplay()); 
       System.out.println("\n-------------------------------------------------------------\n"); 
      } 

    } catch (Exception e) { 
     e.printStackTrace(); 
    } 

} 

Answer 1

CommentThreadListResponse videoCommentsListResponse = youtube.commentThreads() 
.list("snippet").setVideoId(videoId).setTextFormat("plainText").execute(); 

изменения выше код этого работал,

CommentThreadListResponse videoCommentsListResponse = youtube.commentThreads() 
.list("snippet").setVideoId(videoId).setMaxResults(50l).setTextFormat("plainText").execute(); 

Answer 2

Вы можете получить комментарии в видео на YouTube с помощью CommentThreads. Ресурс commentThread содержит информацию о потоке комментариев YouTube, который содержит комментарий и ответы на высшем уровне, если таковые имеются, к этому комментарию. Ресурс commentThread может представлять комментарии о видео или канале.

Вот пример HTTP-запроса для получения комментариев.

https://www.googleapis.com/youtube/v3/commentThreads?key=YOUR_API_KEY&textFormat=plainText&part=snippet&videoId=Vm8qiuDgcJ8&maxResults=50 

Просто проверить различные parameters, которые вы можете использовать в запросе.

В этой документации вы также можете проверить разные sample code.

Вот пример JAVA.

/** 
* This sample creates and manages comments by:

* 2. Replying to a comment thread via "comments.insert" method. 
* 3. Retrieving comment replies via "comments.list" method. 
* 4. Updating an existing comment via "comments.update" method. 
* 5. Sets moderation status of an existing comment via "comments.setModerationStatus" method. 
* 6. Marking a comment as spam via "comments.markAsSpam" method. 
* 7. Deleting an existing comment via "comments.delete" method.
