I am following this guide - https://www.playframework.com/documentation/2.1.1/JavaGuide4#Implementing-authenticators
I have implemented the authenticator as below in Scala:
package controllers
import play.mvc.Security
import play.mvc.Http.Context
import play.mvc.Result
import play.mvc.Results
class Secured extends Security.Authenticator {
override def getUsername(ctx: Context) : String = {
return ctx.session().get("username");
}
override def onUnauthorized(ctx: Context) : Result = {
Results.redirect(routes.Application.login())
}
}
I applied it as an annotation to the hello action in the below controller.
package controllers
import services.UserServiceImpl
import models.User._
import play.api.mvc._
import play.mvc.Security.Authenticated
object Application extends Controller {
def index = Action {
Ok(views.html.index("Your new application is ready."))
}
@Authenticated(classOf[Secured])
def hello = Action {
Ok("Hello")
}
def login = Action {
Ok("Login")
}
}
I am using Play 2.4 and play.api.mvc.Controller instead of play.mvc.Controller as in the guide. Is this the reason this is not working? How do I get it to work with play.api.mvc.Controller?
I figured an example would probably help explain things. If you want similar functionality in Play Scala you would do something like the following:
object AuthenticatedAction extends ActionBuilder[Request] {
def invokeBlock[A](request: Request[A], block: (Request[A]) => Future[Result]) = {
request.session.get("username") match {
case Some(user) => block(request)
case None => Redirect(routes.Application.login())
}
}
You would then use this in your controller:
def hello = AuthenticatedAction { implicit request =>
Ok("Hello")
}
