grails+spring-security-facebook listen to login success event

Question

im a newbie both in spring security and spring-security-facebook and in an app that we are building we have to couple them.Everything is working well i will need to know the way to listen to the facebook login success event. is there some one that already did a stuff that impose him to catch the facebook event success?? I need that because in the begining of the app (before adding the spring -security-Facebook plugin ); we have a special behaviour attached to the "grails.plugins.springsecurity.onInteractiveAuthenticationSuccessEvent" event (configured in the config.groovy file) and we have to execute the same special behaviour when the user connect with facebook account. Is there an event (extending springsecurity kinds of events) that we have to listen to?

any idea ??

Ps: when searching for solution we found a way to catch the FB js Events and work around to reach what we want as result but we would as possible to want to not go that way ....

Answer 1

The problem with it that current Spring Security Facebook authenticates user on each request (by listening to FB cookie, transparently), so you'll get this event on each request. Probably it's not what you want, right? It the same as having a filter on each request.

Btw, you can handle situation when user login into your app first time, but implementing onCreate(user, token) or afterCreate(user, token) in service FacebookAuthService (you have to create such service at this case)

Example:

File grails-app/services/FacebookAuthService.groovy :

class FacebookAuthService {

    void afterCreate(def user, def token) {
        log.info("New user!") //or any code there
    }

}
