RupB Facebook toolkit - sample needs update, can't get to FacebookSession instance
Hi,
In the Facebook toolkit, this sample
public class FBToolkitPageController {
public FacebookApp__c fbc { get; set; }
public FacebookConnection fbConnection { get; set; }
public List<String> friendsList { get { return FacebookConnection.friendsList; } set; }
public FBToolkitPageController() {
if (FacebookConnection.fbApp != null) {
System.debug(LoggingLevel.INFO, FacebookConnection.fbApp.AppKey__c);
System.debug(LoggingLevel.INFO, FacebookConnection.fbApp.AppSecret__c);
System.debug(LoggingLevel.INFO, FacebookConnection.fbApp.FBUserId__c);
fbc = FacebookConnection.fbApp;
}
}
}
is out of date. Could someone tell me how I can get hold of the current FacebookSession object, once I have connected to Facebook with FacebookConnect ? On the JavaScript/VisualForce side of things, I can reach it like this :
var api = FB.Facebook.apiClient;
var session = api.get_session();
But how do I get hold of this in my controller on the Apex side ?
Thanks for your help,
Rup
Here is an answer to my own question :
Controller, APEX class :
public with sharing class My_Controller extends AbsSocialController { public FBCAuthenticator myauth; public String facebookUserId { get; set; } public String facebookAPIKey { get; set; } public override void setAuthenticator(AbsAuthenticator auth) { monDebug += '> setAuthenticator APPELé'; super.setAuthenticator(auth); myauth = (FBCAuthenticator)auth; if (myauth != null) { facebookUserId = myauth.uid; facebookAPIKey = myauth.APIKey; } return; } // get my Facebook friends public FacebookUserInfo[] getMyFriends() { FacebookSession sess = new FacebookSession(myauth); List<String> params = new List<String>(); params.add('about_me'); params.add('pic'); params.add('activities'); params.add('first_name'); params.add('last_name'); params.add('name'); params.add('is_app_user'); params.add('locale'); params.add('hometown_location'); params.add('status'); return sess.getUserInfo(sess.getFriends(), params); } }
