php – Facebook图形API循环通过分页

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;
    }
}}
