Facebook php - 如何获得专辑封面照片 [英] facebook php - how to get album cover photo

问题描述

我需要使用PHP SDK（Facebook）获得专辑封面照片。
我尝试：

https://graph.facebook.com/ [ALBUM_ID] / picture？type = album，但我得到一个默认图像。 ..例如...获取用户的个人资料图片https://graph.facebook.com/ [USER_ID] /图片？type = square

有人可以告诉我正确的方式来收集相册的封面照片。

谢谢。

你可以使用FQL，这是我首选的方法，提供了很大的灵活性。此代码示例应该是您需要的：

  $ album_id ='6464156415616'; 
 try {
 $ fql ='SELECT pid，src_small FROM photo WHERE pid in（SELECT cover_pid FROM album WHERE aid ='。$ album_id。'AND owner = me（））'; 
 $ param = array（
'method'=>'fql.query'，
'query'=> $ fql，
'callback'=>'' 
 //，'return_ssl_resources'=> 1 //如果您希望源代码来自https 
），请设置此选项; 
 $ fqlResult = $ facebook-> api（$ param）; 
 $ fqlResult ['type'] = $ uploadVal ['type']; 
 
 //获取值
 $ src_small = $ fqlResult ['src_small']; 
 
} catch（异常$ o）{
 print_r（$ o）; 
}

I need to get the album cover photo with the PHP SDK (Facebook). I try with:

https://graph.facebook.com/[ALBUM_ID]/picture?type=album, but I get a default image... for example... to get profile pic of user https://graph.facebook.com/[USER_ID]/picture?type=square

Somebody can tell me the correct way to get cover photo for albums please.

thanks.

解决方案

You could just use FQL, it is my preferred method and offers a lot of flexibility. This code sample should be what you need:

$album_id = '6464156415616';
    try{
        $fql    =   'SELECT pid, src_small FROM photo WHERE pid in (SELECT cover_pid FROM album WHERE aid='.$album_id.' AND owner=me())';
        $param  =   array(
            'method'    => 'fql.query',
            'query'     => $fql,
            'callback'  => ''
            //,'return_ssl_resources'=>1 //set this option if you want the source to come from https
        );
        $fqlResult   =   $facebook->api($param);
        $fqlResult['type'] = $uploadVal['type'];

        //fetch values
        $src_small = $fqlResult['src_small'];                   

    } catch(Exception $o){
      print_r($o);
    }
