Hi Daniel, Before I dive into your question I'd like to highlight that the Java directives are undergoing an intense rewrite just now (they're still experimental, so that's why we must do it now), and will be way more elastic soon: https://github.com/akka/akka/pull/19632/files?diff=unified
So it's not a very good time to invest heavily into the existing JavaDSL. I'll give your exact need a closer look a bit later to see how we cover it in the new DSL. -- Cheers, Konrad 'ktoso’ Malawski Akka @ Typesafe On 15 February 2016 at 16:45:14, Daniel Stoner (daniel.sto...@ocado.com) wrote: The current documentation for AkkaHttp directives: http://doc.akka.io/docs/akka-stream-and-http-experimental/2.0.3/java/http/routing-dsl/directives/index.html#directives-java Says you can filter requests and modify requests/responses. I'd love to be able to implement such a thing - but I've seen no examples of custom directives in Java. Does anyone have an example they could post that shows modifying request/response. My use case is that I need to implement several things (As separate directives): 1) The equivalent of server access logs (Saying someone tried to go to /GET?queryParam=x and this took 120ms to respond) 2) Authentication via an external OAUTH system where requests may be rejected with the equivalent of access denied responses. [Perhaps this is better done as a Handler implementation? What are your thoughts?] I get how I could potentially nest handlers in a way such that I can do: pathSingleSlash().route( get(path("home").route(handleWidth(new AuthenticationHandler(homeHandler))) post(path("home").route(handleWidth(new AuthenticationHandler(homePostHandler))) ) But I think Directives sound like the better place to put this logic at the top of the route tree rather than repeat it constantly in all the bottom leaves.
