Class OauthController

java.lang.Object

edu.ksu.lti.launch.controller.OauthController

@Controller
public class OauthController
extends Object

Controller for obtaining an oauth token for a user. It redirects the user to the Canvas oauth endpoint which requests the user's permission. Once they grant permission, a request comes back here with a "code" which is then used to make another request from the server to Canvas to verify things and finally get the actual token back.
