RestFB 不提供帖子评论

我在用着restfb http://restfb.com/以这种方式获取 Facebook 页面的一些帖子和每个帖子的每条评论：

FacebookClient facebookClient = new DefaultFacebookClient(MY_ACCESS_TOKEN);
Connection<Post> pagePosts = facebookClient.fetchConnection("iPhone.page/feed", Post.class);
for (List<Post> posts : pagePosts)
    for (Post post : posts){
        for(Comment comment: post.getComments().getData()){
        //get number of likes of comment
        }
        String message = post.getMessage();
        String id      = post.getId();
        long timestamp = post.getCreatedTime().getTime()/1000;
        //store info            
    }

当它获取像这样的帖子时，我的问题就出现了this https://www.facebook.com/130489060322069/posts/422930041125702.

它有 140 条评论，但toString()方法给了我：

Post[actions=[...] application=null attribution=null caption=techblr.com comments=Comments[count=157 data=[]] createdTime=Wed Feb 27 14:41:58 CET 2013 ....]

评论的json部分是：

comments=Comments[count=157 data=[]]

count=157

但如果你现在继续看那篇文章，它会说 145...而且没有data!

这可能有什么问题吗？为什么它给我的数据与真实数据不同？

我是这样解决的：

private static List<FBComment> getCommentFromPost(FacebookClient client, String post_id){
    List<String> comments = new ArrayList<FBComment>();

    Connection<Comment> allComments = client.fetchConnection(post_id+"/comments", Comment.class);
    for(List<Comment> postcomments : allComments){
        for (Comment comment : postcomments){
        long likes     = comment.getLikeCount()==null?(comment.getLikes()==null?0:comment.getLikes()):comment.getLikeCount();
        comments.add(comment.getMessage()+" - "+likes);
        }
    }


    return comments;
}
