Facebook FQL查询返回{}

Question

我正在使用FQL从用户的流中获取数据，以构建一个看起来像墙到墙的网页。有两个问题：

  

query =“SELECT post_id，message，created_time FROM stream WHERE filter_key IN（SELECT filter_key FROM stream_filter WHERE uid =”+ user ['uid'] +“AND type ='newsfeed'）AND target_id =”+ uid +“AND actor_id =“+ user ['uid'] +”LIMIT 5“

和

  

query =“SELECT post_id，message，created_time FROM stream WHERE filter_key IN（SELECT filter_key FROM stream_filter WHERE uid =”+ user ['uid'] +“AND type ='newsfeed'）AND target_id =”+ user [' uid'] +“AND actor_id =”+ uid +“LIMIT 5”

他们只会回来：

  

{}

我的查询有什么问题？ 谢谢:)）

Answer 1

尝试检查您用于uid的值..

target_id表示发布到的墙，仅当墙不是actor_id的墙时...

两者永远不会平等。
