public LtiSession getLtiSession()
                         throws NoLtiSessionException

Get the LtiSession object from the HTTP session. It is put there up in the ltiLaunch method. This should really be done using a SpringSecurityContext to get the authenticated principal which could then hold this LTI information. But I'm having serious trouble figuring out how to do this correctly and I need *some* kind of session management for right now. Another approach would be to create this as a session scoped bean but the problem there is that I need to share this session object across controllers (the OauthController to be specific) and this breaks for some reason so I'm rolling my own session management here.

Returns:

The current user's LTI session information

Throws:

NoLtiSessionException - if the user does not have a valid LTI session.
