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.
Thanks kindly,
Daniel Stoner
