Jun Liu Could not get Access token using Auth.AuthToken.getAccessToken in custom Registration Handler
Hi,
Recently I follow https://help.salesforce.com/HTViewHelpDoc?id=sso_provider_facebook.htm&language=en_US to set up a facebook auth.provider, and put the callback URL in my facebook app. and the provider is using a custom handler as below.
after the user login using facebook credentials, and in the handler I always get null value for access token using Auth.AuthToken.getAccessToken('my auth.provider id in org', 'Facebook');
I even tried using Salesforce facebook app instead of mine, but still no luck. Can some one tell me if there is something specific i need to pay attention to to get access token?
public class FacebookHandler implements Auth.RegistrationHandler{
public User createUser(Id portalId, Auth.UserData data){
User[] users = [SELECT Id FROM User WHERE Email = :data.email];
if (users.size() == 0) {
String accessToken = Auth.AuthToken.getAccessToken('0SO28000000XXXXXX', 'Facebook');
System.debug('access token: ' + accessToken);
return null;
}
else if (users.size() == 1)
{
User u = users[0];
System.debug('User Id: ' + u.Id);
String accessToken = Auth.AuthToken.getAccessToken('0SO28000000XXXXXX', 'Facebook');
System.debug('access token: ' + accessToken);
//return the user to login as
return u;
}
Many thanks in advance,
Jun Liu

Edit userinfo endpoint in your facabook Auth.provider to retrieve specific user attributes. Something like this:
https://graph.facebook.com/me?fields=picture,name,id,email
And modify the reg. handler to extract the attributes from the attributeMap and create/update the user as follow:
for(string key : data.attributeMap.keySet())
{
data.attributeMap.get(key));
if(key == 'name')
u.name = data.attributeMap.get('name');
...
}
