Feed中的共享配置文件链接在JSON图形API中的数据不足

Question

I was wondering if there is a way to show the actual profile that has been shared on the page feed. Right now the fields that are returned don't give much information.

I'm grabbing the feed as a json object, convert it to a php variable with json_decode and iterate over the returned array.

Everything works just fine except when someone links to a profile of a page in their feed.

$fields = "id,message,picture,full_picture,link,name,description,type,icon,created_time,from,object_id,source";

https://graph.facebook.com/{$fb_page_id}/feed?access_token={$access_token}&fields={$fields}

Regular data item:

[2] => Array
    (
        [id] => 12312452343463463_31253215252
        [message] => Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. 
        [picture] => https://www.picture.com/ADSASD1223
        [full_picture] => https://www.picture.com/ADSASD1223_full
        [link] => http://www.link.com/
        [name] => Linkage
        [description] => Linkage is a link provider
        [type] => link
        [icon] => https://www.facebook.com/images/icons/post.gif
        [created_time] => 2016-02-23T16:07:05+0000
        [from] => Array
            (
                [name] => Test
                [id] => 1233434564567
            )

    )

Profile data item:

[3] => Array
    (
        [id] => 31248734871234_312498341278341278
        [message] => Look!  It's John the Deer! Make sure to follow him!
        [type] => status
        [created_time] => 2016-02-21T19:16:24+0000
        [from] => Array
            (
                [name] => Test
                [id] => 1343143414314314
            )

    )

As you can see there is no link or no image for the actual linked profile.

Answer 1

Thanks to CBroe's suggestion I got the ID from the particular post and tried all the fields for the post object.

The field story_tags ended up being the one.

It returns the following:

"story_tags": [ { "id": "0909030339039", "name": "Name of the person or page that shared the profile", "type": "page", "offset": 0, "length": 23 }, { "id": "91238193129", "name": "Shared Profile Name", "type": "user", "offset": 33, "length": 7 }

I'm not sure what the offset and length refer to but with the id value I can finally see and have access to the shared profile.
