You probably want classpath instead of directory if you're deploying an app

[Nezteb]

Yeah I just wanted to get something working quickly. What’s the easiest way to take a generated swagger.json and add it to the classpath?

[dave]

You've got 2 options here. Either run it through a test to retrieve/manipulate the JSON and put it in a place that ends up in the JAR file, or proxy a call from another route through to the contract handler and alter it on the way through

[Nezteb]

Cool; I started working on the second piece a little bit ago. although the HTTP client is timing out, even though it’s a relatively small swagger file

[dave]

you don't need to use an http client to do it.

[dave]

you can just hard wire the call from one handler to the contract

[dave]

or even wrap the contract in a filter to check the path and then translate the result

[Nezteb]

this is what i was going for

[dave]

yeah - that's probably overkill. give me a mo

[dave]

try this:

val overallApp = Filter { next ->
        {
            next(it).run {
                if (it.uri.path == "/") body(bodyString().reversed()) else this
            }
        }
    }.then(
        contract {
            renderer = SimpleJson(Jackson)
            routes += "/foo" bindContract Method.GET to { Response(Status.OK) }
        }
    )

    println(overallApp(Request(Method.GET, "/")))

[dave]

@Nezteb your filter wraps the entire contract and manipulates the JSON on the way out

[dave]

(that's the other renderer we ship with I'm using there)

[dave]

but you get the idea

[dave]

outputs:

HTTP/1.1 200 OK
content-type: application/json; charset=utf-8

}}">nwonknu<":"oof/:TEG"{:"secruoser"{

[Nezteb]

ahhh, okay. so i’m doing this now. although i stepped over the breakpoint and the request is taking forever to finish. 🤔

[Nezteb]

even if i have it hit /health, which just blindly returns response OK

[dave]

can you reduce the problem a bit - there is a lot going on there? for a start, which server is it hitting, Ktor or SunHttp?

[Nezteb]

Right now SunHTTP. The ktor one was my idea for prod since the docs suggest not using SunHTTP

[dave]

So it hangs? that's weird. What happens if you call the Handler without turning it into a server? presumably that works ok?

[Nezteb]

[dave]

your logging filter seems to be attempting to serialise the entire response?

[dave]

(suspect it's getting the input stream from the response body)

[Nezteb]

🤦 I owe you a beer. Or kombucha.

[dave]

all good then?

[dave]

(beer definitely 🙂 )

[Nezteb]

Yeah, I forgot I even had that logging filter, let alone that all it was doing was printing the request to the console 😄

[dave]

there's DebuggingFilter.PrintResponse() for that kind of thing. by default it doesn't print out streams

[dave]

(you'll notice that a lot of these problems we've come across before! 🙂 )

[Nezteb]

Now that I know about the Filter.NoOp thing, I can definitely use that to conditionally apply filters 😄
