To answer my own question I needed to use the low-level API for the
HttpEntity. I was able to accomplish what I needed to do by using the
toStrict() converter and then continuing the processing work in a lamba.
This is more or less what my complete solution looks like now:
public class MyRequestHandler extends UntypedActor {
ActorRef originalSender;
public void onReceive(Object msg) throws Throwable {
if (msg instanceof RequestContext) {
RequestContext context = (RequestContext)msg;
originalSender = getSender();
if (context.getRequest().method() == HttpMethods.POST) {
ActorMaterializer materializer = ActorMaterializer.create(getContext());
CompletionStage<HttpEntity.Strict> entityFuture =
context.getRequest().entity().toStrict(1000, materializer);
entityFuture.thenApplyAsync(entity -> {
// Do more work here...
// Access entity string as
entity.getData().utf8String()
HttpResponse httpResponse = HttpResponse.create()
.withStatus(StatusCodes.OK);
originalSender.tell(httpResponse, getSelf());
getContext().stop(getSelf());
}
}
}
}
}
