Hello there,
I am trying to write a custom directive in akka http for something like
authorize (with a bit of difference from what's available OOTB).
object AuthenticationUtils {
def generateUserRequest(implicit system: ActorSystem, executionContext:
ExecutionContext): Directive1[UserRequest] = {
optionalHeaderValueByName("Authorization").flatMap {
case Some(tokenValue) if Token.isValidTokenHeader(tokenValue) =>
val token = Token.fromHeader(tokenValue).get
val selection = system.actorSelection(
"myauthenticator-actor-selection-here")
implicit val timeout: Timeout = Timeout(2 minutes) //may be
implicit timeout?
val future = (selection ? RedisTokenActor.GenerateUserRequest(token
)).mapTo[GenerateUserRequestResponse]
.map { r => r.optUserRequest}
/*onSuccess(future) { //this does not work.
case Some(ur) => provide(ur)
case _ => reject(AuthorizationFailedRejection)
}*/
val res = Await.result(future, timeout.duration) //todo: make this
async.
res match {
case Some(ur) => provide(ur)
case _ => reject(AuthorizationFailedRejection)
}
case _ => reject(AuthorizationFailedRejection)
}
}
}
My question is that, how do I async the execution of the `future` within a
directive? When I use onSuccess, the return objects are not compatible.
Please advice on how do I resolve this. When I use it synchronously, the
above code works as desired.
Thanks
Muthu
