A little complex path matching in Akka HTTP

I'm new to Akka HTTP, and trying to write my first API. The routing DSL seems a little confusing.
I managed to match the following:
/channel
/channel/channelName
But now I need to match the following:
/channel/channelName/channelAction
And I can't get it to work.
I currently have:
private val routes: Route =
path("channel") {
get {
reportAllChannelsStatus()
}
} ~
pathPrefix("channel" / Remaining) { channelName =>
get {
singleChannelRequest(channelName, status)
} ~
post {
entity(as[ChannelRequest]) { request =>
singleChannelRequest(channelName, request.channelAction)
}
}
} ~
completeWith404()
I want to add get and post for /channel/channelName/channelAction
Any idea how is this done? (extract both channelName and channelAction)

FWIW, if you have the choice, you might want to consider Play for your web apps. I know it doesn't answer your question, but it's much better suited.

@erip I am implementing an HTTP API on an already huge system that uses Akka Actors, and Akka HTTP Client to make external requests, so I decided to go with Akka HTTP, which everything needed in already included in the project.

Every other thing in the Lightbend stack ues Akka actors extensively, Play included.

Akka http is totally fine for API writing, and I believe you'll find no more value for writing API in Play. For full web backend (like e.g if you need to render web pages), maybe you'll want to go Play.

You can match

}
Be aware that for different types of arguments, you'll have to match different things. Segment is for String, IntNumber would be for Int ...
