Facebook的FQL API - API錯誤：1：發生未知錯誤

Question

我有一個FQL查詢，給出page_id找到您的Facebook朋友的照片location_post。

rest_client.fql_query("SELECT id, page_id, author_uid, coords, type, timestamp FROM location_post WHERE author_uid IN (SELECT uid2 FROM friend WHERE uid1=me()) AND type = 'photo' AND page_id = 212068492162618") 

但是，它返回APIERROR：1：發生未知的錯誤

Koala::Facebook::APIError: 1: An unknown error occurred from /opt/local/lib/ruby/gems/1.8/gems/koala-1.0.0/lib/koala/rest_api.rb:16:in rest_call' from /opt/local/lib/ruby/gems/1.8/gems/koala-1.0.0/lib/koala.rb:55:in api' from /opt/local/lib/ruby/gems/1.8/gems/koala-1.0.0/lib/koala/rest_api.rb:13:in rest_call' from /opt/local/lib/ruby/gems/1.8/gems/koala-1.0.0/lib/koala/rest_api.rb:7:in fql_query' from (irb):51 from :0

如果我擺脫要麼author_uid的IN（SELECT UID2從相知WHERE UID1 =我（）），如以下或PAGE_ID = 212068492162618，然後它

rest_client.fql_query("SELECT id, page_id, author_uid, coords, type, timestamp FROM location_post WHERE AND type = 'photo' AND page_id = 212068492162618 LIMIT 500") 

知道爲什麼這會發生？

感謝

我相信你正在尋找嘗試查詢

SELECT ID，PAGE_ID，author_uid，COORDS，類型，時間戳記location_post其中type = '照片' AND PAGE_ID = 212068492162618"

這會自動展開給你所有的朋友，如上例 https://developers.facebook.com/docs/reference/fql/location_post/
