Facebook API不返回所有带有访问令牌的公共页面墙贴

Question

I am using the PHP Facebook API but it doesn't return all of the wall posts from my public page with a valid access token - and I can't figure out what's so special about those posts. They were all made by me, the page owner - Any ideas?

FYI the posts that arent working contain: https://www.facebook.com/events/205819312854732/ https://www.facebook.com/events/207820205995213/

PHP is: $wall = $validFacebookObject->api('/184196778359304/feed?access_token=".$validToken','GET');

You can't get ALL posts in one call. If you look at the bottom of the response you'll see:

"paging": {
    "previous": "https://graph.facebook.com/184196778359304/feed?format=json&limit=25&since=1334425968&__previous=1",
    "next": "https://graph.facebook.com/184196778359304/feed?format=json&limit=25&until=1331389779"
  }

You can either use the "next" and "previous" URL's to parse through the posts, or include "limit" and "offset" parameters in your calls (ie: graph.facebook.com/PAGE_ID/feed?limit=100&offset=500&access_token=ACCESS_TOKEN will get posts 501 to 600)
