json api图调用不返回任何东西？ [英] json api graph call does not return anything?

问题描述

我正在获取用户fb newfeed，我想得到检查wether用户喜欢的帖子或不使用user_likes，问题是以下代码不会返回任何东西：

i am fetching users fb newfeed and i wanted get check wether user has liked the post or not by using user_likes and the problem is that the following code wont return anything :

$getlike = $facebook->api("/fql?q=SELECT like_info FROM stream WHERE post_id=" . $id);
$checklike = $getlike['data'][0]['like_info']['user_likes'];

这是完整的文件： testone.php
的问题是，fql和调用user_likes不会返回任何东西。
i想检查wether用户已经喜欢的帖子已经 OR 如何获取user_likes的值。

here is the complete file: testone.php the problem is that the fql and calling user_likes wont return anything. i want to check wether user has liked the post already OR how can i get the value for user_likes.

从fb的JSON：

JSON from fb :

{
  "data": [
    {
      "like_info": {
        "can_like": true, 
        "like_count": 70, 
        "user_likes": false
      }
    }
  ]
}

我的技术是否正确？我需要访问代码吗？

is my technique right?do i need access code or something?

推荐答案

如果您获得 $ getlike 的值，则可以检查 user_likes的值这样（因为它是类型boolean） -

If you are getting the value of $getlike, you can check the value of user_likes like this (since it is of type boolean)-

if($getlike['data'][0]['like_info']['user_likes'])
{
    echo "true";    
}
else 
{
    echo "false";   
}
