[akka-user][deprecated] Re: akka http custom directive - async
oops, I'm sorry, I understood it:
def withActiveSession: Directive1[Session] = {
optionalHeaderValueByName("session").flatMap {
case Some(session) =>
val s = Session(session)
onSuccess(sessionRepository.validateSession(s)).flatMap { result =>
if (result) {
provide(s)
} else {
reject(MalformedHeaderRejection("session", "This session is not
active"))
}
}
case None =>
reject(MissingHeaderRejection("session"))
}
}

[akka-user][deprecated] Re: akka http custom directive - async
Also faced such a problem:
def withActiveAuth: Directive1[Session] = {
optionalHeaderValueByName("session") {
case Some(session) =>
val s = Session(session)
onSuccess(sessionRepository.validateSession(s)) { result =>
if (result) {
provide(s) <-- ERROR
} else {
reject(MalformedHeaderRejection("session", "This session is not
active"))
}
}
case None =>
reject(MissingHeaderRejection("session"))
}
}
Error:(18, 22) type mismatch;
found :
akka.http.scaladsl.server.Directive1[wtf.scala.coursetest.Session]
(which expands to)
akka.http.scaladsl.server.Directive[(wtf.scala.coursetest.Session,)]
required: akka.http.scaladsl.server.RequestContext =>
scala.concurrent.Future[akka.http.scaladsl.server.RouteResult]
provide(s)
