Facebook API变化？ PHP获取页数错误

Question

Facebook API Broken?

Ive got this code ive been using for a while now that looks at a facebook page and reports back how many fans the page has. However over the past few days its stopped working and im now getting the following error. Can anyone shed any light on why this is happening?

Error:

Warning: file_get_contents(https://graph.facebook.com/themeparkguide?access_token=2007*********3|9b5***********fcd&fields=fan_count): failed to open stream: HTTP request failed! HTTP/1.1 403 Forbidden in /homepages/28/d541****/htdocs/*********project/facebook_stats.php on line 4
0

Code:

<?php
function fbLikeCount($id,$appid,$appsecret){
  $json_url ='https://graph.facebook.com/'.$id.'?access_token='.$appid.'|'.$appsecret.'&fields=fan_count';
  $json = file_get_contents($json_url);
  $json_output = json_decode($json);
  //Extract the likes count from the JSON object
  if($json_output->fan_count){
    return $fan_count = $json_output->fan_count;
  }else{
    return 0;
  }
}
echo fbLikeCount('coregenie','___APPID___','___APPSECRET___');

It works in the API Explorer: https://developers.facebook.com/tools/explorer/?method=GET&path=themeparkguide%3Ffields%3Dfan_count&version=v2.12

So i assume with some error logging, you would get the error that your App is inactive. Try with a different or new App instead. This should not be affected by the recent changes.

Side note: You should not use that script on every page load, better cache the result for some time. If a lot of users visit the page in a short time, you will hit the rate limit.
