獲取Facebook事件場地經緯度

Question

您好，我使用下面的代碼，以根據提供的URL從facebook獲取事件信息。

的代碼是這樣的：

function importEvent($url) 
{ 
    $facebook = new Facebook(array(
      'appId' => 'someAppId', 
      'secret' => 'someSecret', 
      'cookie' => true, // enable optional cookie support 
     )); 

    if(checkLogin()==true) 
    { 
     //get rid of hash if exists 
     $hash = explode('#',$url); 

     if(!empty($hash[1])) 
      $array = parse_url($hash[1]); 
     else 
      $array = parse_url($hash[0]); 

     parse_str($array['query'],$output); 
     $eid = $output['eid']; 

     if(empty($eid))//new url think http://www.facebook.com/events/2323423423423/ 
     { 
      $url = str_replace('http://www.facebook.com/events/','',$url); 
      $url = str_replace('https://www.facebook.com/events/','',$url); 
      $hash = explode('/?',$url); 

      if(!empty($hash[1])) 
       $url = $hash[0]; 

      $eid = str_replace('?','',$url); 
      $eid = str_replace('/','',$url); 
      //print_r($eid); 
     } 
      //Calling users.getinfo legacy api call example 
      try{ 
       $param = array(
        'method' => 'events.get', 
        'eids' => $eid, 
        'access_token' => $_SESSION['access_token'] 

       ); 
       $events = $facebook->api($param); 
      } 
      catch(Exception $o){ 
       error_log($o); 
       echo $o; 
      } 

     print_r($events); 
     return $events; 
    } 
} 

我得到的輸出是這樣的：

Array 
(
    [0] => Array 
     (
      [eid] => 410474065693887

      [declined_count] => 509 
      [not_replied_count] => 6957 
     ) 

) 

但是在API文檔裏提到，場地包含以下內容：

的此事件的位置 generic access_token，user_events或friends_events 包含以下一個或多個字段的對象：id，s treet，城市，州，郵編，國家，緯度和經度領域。

但我得到的是場地身份證。

我無法找到如何獲取經緯度+場地場所的LNG一段特定的信息，我認爲這個代碼是確定的，如果我沒有記錯。

我是否需要爲場地信息執行另一個查詢，如果可以，請提供任何參考或代碼示例？或者有一種方法可以讓這段代碼返回lat + lng，所以我不必爲1個事件做2個查詢？

Answer 1

經過一番研究，我發現這可能是用fql.multiquery做的，現在看起來工作正常。這是源代碼。

function importEventFQL($url) 
{ 
    $facebook = new Facebook(array(
      'appId' => 'someApddID', 
      'secret' => 'someSecret', 
      'cookie' => true, // enable optional cookie support 
     )); 

    if(checkLogin()==true) 
    { 

     list($url_static,$url_URI) = explode('/events',$url); 

     $url_URI = ltrim($url_URI,'/'); 
     list($eid, $trash) = explode('/?',$url_URI); 

     $fql = '{'; 

     $fql .= '"event_info":"SELECT name, description, pic_small, pic_big, eid, venue, location, start_time, end_time, host from event WHERE eid=\'' . $eid . '\'",'; 
     $fql .= '"event_venue":"SELECT name, username, page_id, location FROM page WHERE page_id IN (SELECT venue.id FROM #event_info)"'; 

     $fql .= '}'; 

     $param = array(
      'method' => 'fql.multiquery', 
      'queries' => $fql, 
      'callback' => '' 
     ); 

     $result = $facebook->api($param); 

     print_r($result); 
    } 
} 

Answer 2

如果你只想要FQL做到這一點：

{ 
    "events" : "SELECT privacy, name, description, start_time, venue.id, pic_cover FROM event WHERE eid IN (SELECT eid FROM event_member WHERE uid = me())", 
    "venues" : "SELECT latitude, longitude, name, page_id FROM place WHERE page_id IN (SELECT venue.id FROM #events)" 
}
