Can you view a friendship relationship's data (the "You and a friend" page) via the Facebook API? [duplicate] - api

Question

How can I get a friendship detail for two people? So for example in the web it will be:
http://www.facebook.com/<my_id>?and=<friend_id>
Is there any way I can do this in Graph API? Furthermore can I get specific items such as photos together, wall posts between us, etc? (Not documented AFAIK, but many Graph API features aren't anyway...)
EDIT: I think it should be possible with Graph API. For example getting family details (brother, sister, parents, etc) is not documented yet I still able to do it.

Answer 1

You can simulate a friendship query by doing multiple FQL queries. For example, to get all the photos between two friends A and B, you can:
Get all photos (p) from A
Get all tags of B in p (query on the photo_tags table)
Get all comments made by B on p (query on the comments table)
Repeat, this time selecting photos from B.
You can apply the same concept on other things such as posts, likes, videos etc.

Answer 2

Yes, I think you can also do the same thing phillee answered with the Graph API instead of FQL:
Get user's photos https://graph.facebook.com/USERID/photos
Get each photo's tags https://graph.facebook.com/PHOTOID/tags
Sort through the list of photo tags, and grab all photos with the Friend in them
Get each photo's comments https://graph.facebook.com/PHOTOID/comments
Sort through the list of photo comments, and grab all comments left by the friend
As the other answer also said: rinse and repeat for all data you want
https://graph.facebook.com/USERID/feed
https://graph.facebook.com/USERID/posts
etc etc, see all connections here: http://developers.facebook.com/docs/reference/api/user/
For the interests, movies, activities, etc just make an API call for both (https://graph.facebook.com/ONEUSER/music and https://graph.facebook.com/OTHERUSER/music) and find the intersection of the two sets of data (loop through each list and save all matches to a separate list of mutual Likes)
There are no specific API calls for friendships though, so you will have to build your own. My guess is that Facebook is doing exactly this on their Friendship pages :)
It should be just as easy with FQL as with the REST API... maybe even easier with FQL since you can add WHERE conditions and get back just the data you need (SELECT * FROM comments WHERE fromid = FRIENDID), instead of sorting through the big list returned by the API (unless there is a way to add conditions to API request URLs?).

Answer 3

If I understand properly you want to "View Friendship"
This type of query is not directly possible using the Graph API (at the moment). You would need to gather the information from each resource endpoint and then do some relating on your own part to "View Friendship"

Answer 4

This is what I have been using:
<?php
function main()
{
global $Fb;
$Fb = new Facebook(array('appId'=>FB_API_ID,'secret'=>FB_API_SECRET));
$logoutUrl = $Fb->getLogoutUrl();
$loginUrl = $Fb->getLoginUrl();
$user = fb_loguser($Fb);
if ($user)
{
$txt .= "<p align=\"center\">Logout</p>";
$txt .= "<h3 align=\"center\">You</h3>";
$access_token = $Fb->getAccessToken();
$user_profile = $Fb->api('/me');
$txt .= "<p align=\"center\">
<img src=\"https://graph.facebook.com/".$user."/picture\"></p>";
$txt .= fb_friends_list($user_profile,$access_token);
}
}
function fb_loguser($facebook)
{
global $Fb;
$Fb = $facebook;
$user = $Fb->getUser();
if ($user)
{
try
$user_profile = $Fb->api('/me');
catch (FacebookApiException $e)
{
error_log($e);
$user = null;
}
}
return($user);
}
function fb_friends_list($access_token)
{
global $Sess,$Fb;
$friends = $Fb->api('/me/friends'); // return an array [data][0 to n][name]/[id]
$siz = sizeof($friends['data']);
$txt = "<h3>Your FRIENDS on FACEBOOK</h3>";
$txt .= "<table>";
for ($i=0; $i<$siz; $i++)
{
$fid = $friends['data'][$i]['id'];
$src = "http://graph.facebook.com/".$fid."/picture";
$txt .= "<tr><td><img src=\"".$src."\" /></td>";
$txt .= "<td>".$friends['data'][$i]['name'] . "</td>";
$txt .= "<td>" . $fid . "</td></tr>";
}
$txt .= "</table>";
return($txt);
}
?>
Call main()!

SELECT pid, src_big FROM photo
WHERE pid IN(

AND pid IN(
SELECT pid FROM photo_tag WHERE subject=ANOTHER_FRIEND_ID)
