如何使用restfb在Facebook中获取评论图片？

Question

I'm having troubles getting the attached image of a comment to a status update in a Facebook page using restfb.

I'm commenting a status update in the page (did by myself) and adding a picture. I'd like to get that picture, but the Comment object returned has always the attachment set to null...here is the code:

JsonObject commentAsObject = FacebookUtils.getCommentAsObject(access_token, commentId);
Comment comment = FacebookUtils.getComment(access_token, commentId);
if (comment.getAttachement() != null)
    //Do something

The commentId is valid, I build the permalink using that ID and it works...and the returned Comment object has all the values, like message OK, but the picture is not present...thus, does restfb return any of this?

Thanks!

您构建的用于获取注释的请求需要fields=attachment参数，因为只有明确请求时才返回此字段。
