用户是否“喜欢”一个Facebook的帖子已经 [英] Does a user "like" a Facebook post already

问题描述

我一直在试图解决这个问题，并且慢慢地意识到通话来电不是我想要的呼叫。

I have been trying to solve this one for a while now and have slowly realised that the call im making is not the desired call for what i want.

我目前正在收到用户的新闻源，并添加了一个类似的按钮，但如果他们喜欢它，它说不像。

I am currently getting the users newsfeed and adding a like button but if they like it already it shold say unlike.

我打电话/我/喜欢...并获得几点数据（我通过比较新闻源中的每个帖子ID拖网），但我刚刚意识到此数据与用户喜欢的页面相关。它不返回用户喜欢的帖子。

i call /me/likes?... and get a couple of bits of data (which i trawl through comparing each post id in newsfeed) but I have just realised this data is to do with pages that the user has liked. It doesn't return the posts the user has liked.

我的问题是我如何确定用户是否已经喜欢过一个帖子？（我的恐惧是，我必须打电话给api的每个帖子在新闻来确定用户是否喜欢这篇文章，但会大大减慢移动应用程序的速度）。

My question is how do i determine if the user has liked a post already?(my fear is that i have to make a call to the api for each post in the newsfeed to determine if the user likes this post but that would drastically slow down a mobile app).

推荐答案

只需使用FQL 像 表：

Simply using FQL like table:

SELECT post_id 
FROM like 
WHERE post_id 
IN ("AAAAAA_AAAAAAAAAAA","BBBBBB_BBBBBBBBB","CCCCCCC_CCCCCCCCC") 
AND user_id = XXXXXXXXX

结果将是： / p>

And the result will be something like:

[
  {
    "post_id": "CCCCCCC_CCCCCCCCC"
  }
]

在 fql.query console 。

It's always a good idea to test your queries in the fql.query console.
