Sure.
P.s. @Marek here is a workaround so you can continue working until
this is fixed. It is a directive that transforms the HttpEntity to
strict. Here is the fixed file in the gist:
https://gist.githubusercontent.com/rklaehn/d4d3ee43443b0f4741fb/raw/f1fba061eac5d13dd19523f2df9660500a5a8129/UploadHandlerToStrict.scala
@Roland does a directive like this exist somewhere? It might be useful.
def toStrict(timeout: FiniteDuration): Directive[Unit] = {
def toStrict0(inner: Unit ⇒ Route): Route = {
val result: RequestContext ⇒ Future[RouteResult] = c ⇒ {
// call entity.toStrict (returns a future)
c.request.entity.toStrict(timeout).flatMap { strict ⇒
// modify the context with the strictified entity
val c1 = c.withRequest(c.request.withEntity(strict))
// call the inner route with the modified context
inner()(c1)
}
}
result
}
Directive[Unit](toStrict0)
}
