Question

您好我使用以下代码，以便根据提供的网址从Facebook检索事件信息。

代码是这样的：

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;
    }
}

我得到的输出是：

            [not_replied_count] => 6957
        )

)

然而，在api文档中，它提到该地点包含以下内容：

此活动的位置通用access_token，user_events或friends_events 包含以下一个或多个字段的对象：id，street，city，state，zip，country，latitude和longitude fields。

但我得到的只是场地ID。

我无法找到有关如何检索场地的lat + lng的特定信息，我认为如果我没有弄错的话，这段代码是可以的。

我是否需要仅针对场地信息执行另一个查询，如果可以，请提供任何参考或代码示例？或者这段代码是否有办法返回lat + lng，所以我不必为1个事件做2个查询？

Answer 1

经过一些研究后，我发现这可以用fql.multiquery做，现在看起来效果很好。这是源代码。

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

如果您只想让FQL执行此操作：

{
    "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)"
}

获取Facebook活动场所的纬度和频率经度
