You can retrieve the comments in YouTube video by using the CommentThreads
. A commentThread resource contains information about a YouTube comment thread, which comprises a top-level comment and replies, if any exist, to that comment. A commentThread resource can represent comments about either a video or a channel.
您可以使用CommentThreads检索YouTube视频中的评论。 commentThread资源包含有关YouTube评论主题的信息,其中包含*评论和对该评论的回复(如果存在)。 commentThread资源可以表示有关视频或频道的评论。
