Thanks for your response!
Is it possible to combine it with play-json?
My spray function I'm trying to rewrite looks like
def jsonRoute(fn: => ToResponseMarshallable, method: Directive0 = get): Route
= method {
val jsonResponse = respondWithMediaType(`application/json`) {
complete(fn)
}
if (corsAllowed) respondWithHeader(RawHeader("Access-Control-Allow-Origin",
"*"))(jsonResponse)
else jsonResponse
}
I still can't see how to combine your response (even the `hacking` one)
with ToResponseMarshallable..
