fql.multiquery返回空數組

我正在查詢頁面的所有相冊並獲取每張專輯的封面照片。下面是我有的代碼返回一個空的結果。fql.multiquery返回空數組

我能夠兩個查詢分開沒有問題，所以它不是一個權限問題。

$album_fql = "SELECT aid, owner, name, object_id, cover_pid, cover_object_id 
       FROM album 
       WHERE owner = 'xxxxxxx'"; 

$albumpic_fql = "SELECT pid, src_small 
       FROM photo 
       WHERE pid IN (SELECT cover_pid FROM #query1)"; 

$album_param = array(
       'method' => 'fql.multiquery', 
       'queries' => '{"query1":"' . $album_fql . '", "query2":"' . $albumpic_fql . '"}'); 

$album_fqlResult = $facebook->api($album_param); 

print_r($album_fqlResult);

任何想法？

是否超時？該頁面是否有大量相冊？ – 2011-12-29 22:09:29

你可以在嵌套查詢而不是多查詢中做到這一點。

SELECT pid, src_small 
FROM photo 
WHERE pid in (SELECT cover_pid FROM album where owner={page id here})

例如這裏的專輯列表中涵蓋了我從可口可樂的Facebook頁面

SELECT pid, src_small 
FROM photo 
WHERE pid in (SELECT cover_pid FROM album where owner=40796308305) 
LIMIT 5

返回了：

    } 
    ] 
}

如果你想試試你multiquery，然後嘗試命名從索引0開始而不是1開始查詢query0和query1這是C＃SDK允許的唯一方式，也許php SDK也是如此。

感謝您的迴應！我還需要得到專輯的名稱，從我讀過的內容來看，這需要我認爲的多重查詢。 – teamdane 2011-12-30 16:07:00

終於明白了。我不得不將這些查詢合併到1個變量中並且轉義單引號。

$queries = '{ 

"query1" : "SELECT aid, name, cover_pid FROM album WHERE owner = \'xxxxxxxxxxx\'", 

"query2" : "SELECT aid, images FROM photo WHERE pid IN (SELECT cover_pid FROM #query1)" 

}';
