Normally we bind inside a with method call. Try calling it with the parens instead of infixed?

Same problem...

[dave]

looks like it only works if you specify the input type

val hello = Header.required("foo").of<HttpMessage>("baa")

[elifarley]

It did the trick. Now, how can solve this:

I have

("/api/v1/${this.path.format(param)}" bindContract GET).let { route: RouteBinder<HttpHandler> ->
                handler.perform(route.newRequest().with(
                        Header.required("Service-Provider-Id") of "my-provider",
                        Header.required("Client-Realm-Id") of catalogName
                  ), this.responseLens as BodyLens<T>
                )
            }

I'd like to have:

fun <T : HttpMessage> serviceProviderIDOf(x: String) = Header.required("Service-Provider-Id").of<T>(x)

val setServiceProviderId = Filter { next ->
    { next(it).with(serviceProviderIDOf("myval")) }
}

    operator fun <T> invoke(handler: HttpHandler, catalogName: String, param: String): Pair<Status, T> =
            ("/api/v1/${this.path.format(param)}" bindContract GET).then(setServiceProviderId).let { route: RouteBinder<HttpHandler> ->
                handler.perform(route.newRequest().with(
                        Header.required("Client-Realm-Id") of catalogName
                  ), this.responseLens as BodyLens<T>
                )
            }

But it doesn't compile...

[dave]

I think you're a little mixed up. bindContract doesn't return anything you can "then" to

[elifarley]

yep, I'm a bit confused

[dave]

bindContract will bind to a function that takes a string and returns an HttpHandler. so you need to attach filters to the response of that handler

[elifarley]

I see...

[elifarley]

The filter I created should be used to add a header to the request.

[dave]

And you'll need to add it everytime - the bond method expects a function that returns a(decorated) httphandler

[elifarley]

Didn't manage to make it work... will skip it for now
