YQL：获取私人Twitter帐户的朋友列表时的空结果

Question

我使用YQL：js来获取数据。

我在https://developer.yahoo.com/yql/console/：

select * from twitter.friends where id='some_not_private_account'

它完美无缺。它返回好友列表。 现在我使用私人帐户做同样的事情：

select * from twitter.friends where id='some_private_account' and 
oauth_consumer_key='some_key' and 
oauth_consumer_secret='some_secret' and 
oauth_token='some_token' and 
oauth_token_secret='some_token_secret'

调试中没有任何错误，但结果部分为空。为什么？我做错了什么？
