使用Facebook API获取所有朋友和喜欢的人

Question

I'm just getting started with a project and wondered if someone can let me know if it's possible to:

A) Get a list of all friends for an authorised Facebook account via the API

B) Get all of the likes for each friend using the API

I saw this code suggested on another question:

FB.api("/likes?ids=533856945,841978743")

FB.api("me/friends",{
  fields:'id',
  limit:10
},function(res){
  var l=''
  $.each(res.data,function(idx,val){
     l=l+val.id+(idx<res.data.length-1?',':'')
  })
  FB.api("likes?ids="+l,function(res){
      console.log(res);
  })
})

But I'm struggling to understand the logic of this as it looks like you need to know the ids to get the likes.

Also is there a limit to the number of likes returned? I read something about it only returning the last X number of likes for each user.

Many thanks!

You can fetch all the friends for an authorized user with the friends.get API call. http://developers.facebook.com/docs/reference/rest/friends.get/

Once you have the list of friends, you can loop through the list and fetch their likes by using the graph API's "likes" call.

Sample "likes" request: https://graph.facebook.com/put_a_fb_user_id_here/likes
