所以我正在使用这个脚本来遍历给定页面中的事件.突然间我发现它不再起作用了:(
我觉得这可能是一个错误,因为如果您选择任何页面,使用access_token查看事件,则无法获取“下一个”分页URL的任何数据.例如在apigee.com上尝试https://graph.facebook.com/evenightclub/events
有任何想法吗？
($fid是页面对象id)
- try {
- $facebook = new Facebook(array(
- 'appId' => '<removed>','secret' => '<removed>',));
- $access_token = $facebook->getAccessToken();
- $events_data = array();
- $offset = 0;
- $limit = 5000;
- $params = array('access_token' => $access_token);
- //fetch events from Facebook API
- $data = $facebook->api("$fid/events/?limit=$limit&offset=$offset",$params);
- $events_data = array_merge($events_data,$data["data"]);
- //loop through pages to return all results
- while(in_array("paging",$data) && array_key_exists("next",$data["paging"])) {
- $offset += $limit;
- $data = $facebook->api("$fid/events/?limit=$limit&offset=$offset",$params);
- $events_data = array_merge($events_data,$data["data"]);
- }}
你的代码对我有用,我唯一做的就是确保count($data [“data”])>在将其与现有信息合并之前为0.所以它看起来像这样：
- //loop through pages to return all results
- while(in_array("paging",$data["paging"])) {
- $offset += $limit;
- $data = $facebook->api("$fid/events/?limit=$limit&offset=$offset",$params);
- // make sure we do not merge with an empty array
- if (count($data["data"]) > 0){
- $events_data = array_merge($events_data,$data["data"]);
- } else {
- // if the data entry is empty,we have reached the end,exit the while loop
- break;
- }
- }}
