Question

我正在使用FQL来运行FB Likes的查询，但是分页看起来似乎很奇怪。第一个查询运行以获取最多400个like_urls，如下所示：

SELECT url from url_like where user_id='FB_USER_ID' LIMIT 0, 400

它在此示例中返回大约25个网址的列表。问题是我有这个循环以防万一它超过400.在这个循环中，查询可能再次运行如下：

SELECT url from url_like where user_id='FB_USER_ID' LIMIT 25, 400

结果是相同的25个URL ...不应该限制25,400忽略每个FQL的前25个？我用来打破循环的机制是，如果返回的结果总计为0，那么这当前将我的查询放入循环中，它只是超时。

有关FDB FQL限制如何工作的任何指针或信息，或LIMIT不适用于like_url的原因将不胜感激。

我所拥有的当前查询的前5次迭代的示例（尽管URL列表显示相同，但结果中的数字甚至显示不一致）

Answer 1

FQL只显示你可以看到的网址..例如，我有10个喜欢，但前3个因某些原因被隐藏：

[0] Hidden
[1] Hidden
[2] Hidden
[3] Public
[4] Public
...
[9] Public

此FQL查询

SELECT url from url_like where user_id='FB_USER_ID' LIMIT 0, 10

只会返回7条记录（公众）..同样会发生

SELECT url from url_like where user_id='FB_USER_ID' LIMIT 3, 10

或

SELECT url from url_like where user_id='FB_USER_ID' LIMIT 100

解决方案是计算所有喜欢的内容，这样你就知道你必须要记录多少条记录......但是 Facebook FQL没有实现'计数'功能。

所以这个问题没有真正解决方案

FB FQL限制分页不起作用（表现奇怪）
