Hello all, in the greetRoute() example (https://www.http4k.org/guide/reference/contracts/), how would I apply a filter before the greet(nameFromPath: String) handler is invoked?

[dave]

you have options. at the lowest level, you can :

fun greet(nameFromPath: String): HttpHandler = filter.then { request: Request ->
        val age = ageQuery(request)
        val sentMessage = stringBody(request)

        Response(OK).with(stringBody of "hello $nameFromPath you are $age. You sent $sentMessage")
    } @

Thanks @dave
