asp.net mvc 4 - Logout link with return URL (OAuth)

Question

My application is integrated with Facebook, Google and Microsoft (using OAuth).

To logout from facebook I'm using the following URL:

https://www.facebook.com/logout.php?next=[YourAppURL]&access_token=[ValidAccessToken]

Is there something similar for Google and for Microsoft?

For Google I tried:

https://accounts.google.com/Logout?continue=http://localhost:51820

But it didn't work... It returns: The page you requested is invalid.

How can I get that URL logout?

Answer 1

I finally got the right links:

• Facebook:

https://www.facebook.com/logout.php?next=[YourAppURL]&access_token=[ValidAccessToken]

Source: A Working Facebook OAuth Logout URL

• Google:

https://www.google.com/accounts/Logout?continue=https://appengine.google.com/_ah/logout?continue=[http://www.mysite.com]

Source: google account logout and redirect

• Microsoft:

https://login.live.com/oauth20_logout.srf?client_id=[CLIENT_ID]&redirect_uri=[REDIRECT_URL]

Source: Server-side scenarios

Those links can be use like that in JavaScript:

function logout (){
document.location.href = "https://www.facebook.com/logout.php?next=[YourAppURL]&access_token=[ValidAccessToken]";
}

Suggestion to implement this: Logout from external login service (Gmail, facebook) using oauth
