How to do logout from Facebook Connection via Spring social

[Madhava Reddy]

Hi all,

I am developing one application in that i am able to login the user using spring-social-facebook api.

and I need to perform logout() functionality, when ever the user sign out from my application, user should also logout from facebook,twitter,etc..

I am using spring security (in my application) for login and logout.


Thanks,
Madhav.

Spring Social's Facebook API binding uses Facebook's Graph API and there is no way that I'm aware of that you can logout a user via the Graph API. Likewise with Twitter and other providers However...

You can accomplish Facebook logout by redirecting to the following URL:

https://www.facebook.com/logout.php?next=YOUR_REDIRECT_URL&access_token=USER_ACCESS_TOKEN

You can also log a user out of FB using FB's JavaScript API by calling FB.logout() from the client-side.

So, after the user is logged out of your app, you could follow that up with a redirect to that FB URL.

I'm not sure that this is necessarily a good thing to do, however. I would think that most users would be a bit upset to find out that by logging out of your app that they are also logged out of Facebook.
