我正在使用restfb在Facebook页面上创建带有child_attachments(轮播)的帖子。

这是创建DefaultFacebookClient并尝试发布帖子的代码:

public String post(List<News> newsList) 
{
    try 
    {
        FacebookClient facebookClient = new DefaultFacebookClient(ACCESS_TOKEN, APP_SECRET, Version.LATEST);

        List<Post> attachments = new ArrayList<>();

        for(int i = 0; i < 4; i++) 
        {
            PostCallToActionValue postCallToActionValue = new PostCallToActionValue();
            postCallToActionValue.setLink(newsList.get(i).GetNewsUrl());
            postCallToActionValue.setLinkTitle(newsList.get(i).GetTitle());

            PostCallToAction postToAction = new PostCallToAction();
            postToAction.setType("NO_BUTTON");
            postToAction.setValue(postCallToActionValue);

            Post post = new Post();

            post.setPicture(newsList.get(i).GetImageUrl());
            post.setName(newsList.get(i).GetTitle());
            post.setLink(newsList.get(i).GetNewsUrl());
            post.setCaption("Asewome description here ...");
            post.setDescription(newsList.get(i).GetDescription());
            post.setCallToAction(postToAction);

            attachments.add(post);
        }

        FacebookType publishMessageResponse = facebookClient.publish(FACEBOOK_PAGE + "/feed", 
            FacebookType.class, 
            com.restfb.Parameter.with("message", "Awesome message here ..."),
            com.restfb.Parameter.with("multi_share_end_card", false),
            com.restfb.Parameter.with("child_attachments", attachments)
        );

        String facebookUrl = "http://www.facebook.com/permalink.php?story_fbid=" + publishMessageResponse.getId() + "&id=" + FACEBOOK_PAGE;

        return facebookUrl;
    } 
    catch (RuntimeException e) 
    {
        throw e;
    }
}

我从Facebook Api收到此错误:

"Received Facebook error response of type OAuthException: (#100) Invalid keys \"likes\" were found in param \"child_attachments[0]\". (code 100, subcode null) 'null - null'"

在对Open Graph进行了大量研究之后,我不知道“喜欢”键是什么。

有什么建议吗?

谢谢!
