[akka-http] IllegalUriException

[Frederic Masion]

Hi everybody,

I have a strange IllegalUriException with akka-http :

My app is quite simple : a logging proxy

I have configured my network to use this proxy for all http requests.

what the proxy does : 

val route: Route =
    logging {
      {
        forward
      }
    }

Http().bindAndHandle (route, "localhost", 8181)

logging directive only extracts method, path... and logs it

to forward Route is defined here :

trait Forwader {this : ProxyDirective =>

  def forward : StandardRoute =
    StandardRoute { (context: RequestContext) =>
      val future = Http().singleRequest(context.request)
      future.fast.transformWith {
        case Success(res) ⇒ context.complete(res)
        case Failure(error) ⇒ context.complete(StatusCodes.InternalServerError, s"An error occurred: ${error.getMessage}")
      }
    }

}

Everything is very basic and works fine with default port BUT I have plenty of ERROR logs like this one :

[ERROR] [09/28/2015 20:38:26.583] [Proxy-akka.actor.default-dispatcher-283] [ActorSystem(Proxy)] Internal server error, sending 500 response

akka.http.scaladsl.model.IllegalUriException: 'Host' header value of request to `notify1.dropbox.com:443` doesn't match request target authority: Host header: Some(Host: notify1.dropbox.com)

[ERROR] [09/28/2015 20:46:21.163] [Proxy-akka.actor.default-dispatcher-386] [ActorSystem(Proxy)] Internal server error, sending 500 response

akka.http.scaladsl.model.IllegalUriException: 'Host' header value of request to `openoox.com:8080` doesn't match request target authority: Host header: Some(Host: openoox.com:8080)

request target authority:

Has soon as the HOST header of the response contains a port with the http protocol I have a IllegalUriException

Did I missed something ?

HI Fred,

I am not sure, but does the Host header allow ports to be defined? I am not sure what the RFC says on this matter, but Akka Http (and Spray) tends to follow the rules by-the-book most of the time.

Hi Frederic,

ports in Host headers should be fine (see http://tools.ietf.org/html/rfc7230#section-5.4) and be supported by akka-http. Just make shure that both host and port of the request URI are the same as in the Host header.

The port checking seems to currently be missing. Therefore I filed https://github.com/akka/akka/issues/18632.
