从Facebook获取专辑

Question

I have tried to fetch all album IDs from facebook using the following code. But only first 25 albums were returned. Did I miss something?

response = facebook.request("me/albums");
json = Util.parseJson(response);
albums = json.getJSONArray("data");
for (int i =0; i < albums.length(); i++) {
    JSONObject album = albums.getJSONObject(i);
    String album_name = album.getString("name");
    String album_id = album.getString("id");
}

Answer 1

But only first 25 albums were returned. Did I miss something?

Yes – that 25 is the default limit parameter value for requests like this.

Either use the paging links to retrieve the next 25 and so on, or set a higher limit yourself.

Answer 2

I use following ways to get the rest of album list.

next_page_URL = null; 
next = json.getJSONObject("paging"); 
next_page_URL = next.getString("next"); 
response = facebook.request("me/albums&"+next_page_URL);
