我正在尝试使用 facebook4j 检索有关 facebook 帖子的所有基本信息。

这是我的代码：

    final Reading reading1 = new Reading().since("-1 month").limit(38).fields("comments", "likes", "id", "message", "caption", "description", "created_time", "from").summary(); 
    final ResponseList<Post> feeds1 = facebook.getPosts("viratkohli", reading1);

    final Reading reading2 = new Reading().since("-1 month").fields("likes", "id", "message", "created_time", "from", "story").limit(100).summary(); 
    final ResponseList<Post> feeds2 = facebook.getPosts("viratkohli", reading2);



    for (int i = 0; i < feeds2.size(); i++) {
        // Get post.
        Post post1 = feeds2.get(i);
        // Get (string) message.
        String message = post1.getMessage();
        Date d = post1.getCreatedTime();
        String id = post1.getId();
       PagableList<Like> pl = post1.getLikes();
       String story = post1.getStory();

       System.out.println("post: "+i+": "+message);
       System.out.println("Created time: "+d.toString());
       System.out.println("id: "+id);
       System.out.println("story: "+story);
       System.out.println();
       for(Like like: pl) {
           String like_name = like.getName();
           String like_id = like.getId();

           System.out.println("like name: "+like_name);
           System.out.println("like id: "+like_id);
           System.out.println();
       }
       System.out.println("******************");

    }

        for(int j=0;j<feeds1.size();j++){
            Post post2 = feeds1.get(j);
            System.out.println(j);
            final PagableList<Comment> comments = post2.getComments();
            for(int k=0; k<comments.size(); k++) {
                // Get comment.
                Comment comment = comments.get(k);
                String id2 = comment.getId();
                String comm = comment.getMessage();
                Date d2 = comment.getCreatedTime();
                Integer co = comment.getLikeCount();

                System.out.println("Comment "+k+": "+comm);
                System.out.println("id: "+id2);
                System.out.println("created time: "+d2);

                }

            System.out.println("~~~~~~~~~~~~~");
            }

目前，我可以获得以下信息：

最大限度。100 个最近的帖子，25 个最近的喜欢，每个帖子的 25 个最近的评论（最多 40 个帖子）。

任何克服限制问题的帮助将不胜感激。

这是正确的答案：

    final Reading reading = new Reading().summary().fields("id", "message", "likes.summary(true)", "shares", "comments.summary(true)").limit(20).since("-1 month"); 
    final ResponseList<Post> feeds = facebook.getPosts("green", reading);

    for (int i = 0; i < feeds.size(); i++) {
        // Get post.
        Post post = feeds.get(i);

       Integer likesCount = post.getLikes().getSummary().getTotalCount();
        Integer sharesCount = post.getSharesCount();
       Integer commentsCount = post.getComments().getSummary().getTotalCount();

       if(sharesCount == null)
           sharesCount = 0;
       if(likesCount == null)
           likesCount = 0;
       if(CommentsCount == null)
           commentsCount = 0;
        System.out.println("No. of shares for post "+i+": "+sharesCount);
        System.out.println("No. of likes for post "+i+": "+likesCount);
        System.out.println("No. of comments for post"+i+": "+commentsCount);
        System.out.println();

如果您只想要喜欢的总数，而不是个人喜欢 - 然后设置limit为 0，然后设置summary为 1。
