Question

当我尝试获取用户使用Facebook4j流播放在墙上的所有Facebook帖子时，我似乎只能获得过去14天的帖子。有没有办法绕过这个限制并让用户在墙上发布的每条消息？

我正在使用分页，并且在过去的两周内收到了550封邮件，但没有更多。

这是我的代码

private void printFBMessages(FileWriter fileWriter, String nameFeed)
        throws InterruptedException, IOException, FacebookException {
    int n = 0;
    boolean notEmpty = true;
    while (notEmpty) {
        try {
            notEmpty = false;
            System.out.println("N: " + n);
            for (Post post : facebook.getFeed(nameFeed, new Reading().limit(100).offset(n))) {
                notEmpty = true;
                MessageInfo msg = new MessageInfo();
                msg.setDate(post.getCreatedTime().toString());
                msg.setTitle(post.getMessage());
                System.out.println(msg);
                n++;

                addControleToResult(fileWriter, nameFeed, msg);
            }
            if (!notEmpty) {
                System.out.println("Empty");
            }
        } catch (FacebookException ex) {
            System.out.println(ex.getMessage());
            Thread.sleep(300000);
        }
        n++;
    }
    System.out.println("Done!");
    return;
}

似乎我正在处理分页错误，这就是为什么它没有按预期工作的原因。

这是实际按预期工作的代码示例：

private void printFBMessages(FileWriter fileWriter, String nameFeed)
        throws InterruptedException, IOException, FacebookException {
    boolean notEmpty = true;

    facebook4j.ResponseList<Post> posts = facebook.getFeed(nameFeed, new Reading().limit(100));

    while (notEmpty) {
        try {
            notEmpty = false;

            for (Post post : posts) {
                notEmpty = true;
                MessageInfo msg = new MessageInfo();
                msg.setDate(post.getCreatedTime().toString());
                msg.setTitle(post.getMessage());
                System.out.println(msg);

                addControleToResult(fileWriter, nameFeed, msg);
            }               
            posts = facebook.fetchNext(posts.getPaging());
        } catch (FacebookException ex) {
            System.out.println(ex.getMessage());
            Thread.sleep(300000);
        }
    }
    System.out.println("Done!");
    return;
}

Facebook4j的帖子限制为过去2周？
