過濾Facebook信息流通過信息隱私？

Question

我查詢我的臉書標籤中的一些牆數據。 我想知道如何過濾數據（查詢），以顯示僅對某個國家可見的帖子。

$query = " SELECT 
      post_id, created_time, attachment,action_links, privacy 
     FROM 
      stream 
     WHERE 
      source_id = ".$page_id." 
      AND viewer_id = ".$user_id." 
      AND actor_id = ".$actor_id." 
     LIMIT 
      50"; 

輸出已顯示澳大利亞：但如何過濾澳大利亞。

Array (
[posts] => Array 
    (
     [0] => Array 
      (
       [post_id] => 123 
       [viewer_id] => 123

我認爲你必須到其他過濾器添加到查詢：

$query = " SELECT 
     post_id, created_time, attachment,action_links, privacy 
    FROM 
     stream 
    WHERE 
     source_id = ".$page_id." 
     AND viewer_id = ".$user_id." 
     AND actor_id = ".$actor_id." 
     AND privacy = ".$your_privacy_filter // Austria, in this case. 
    LIMIT 
     50"; 

也許過濾器必須是這樣的：

//... 
"AND privacy.description = ".$your_privacy_filter
