Best support is in the #http channel in the official Kotlin slack: slack.kotlinlang.org
@scap1784 I've worked it out. The problem was that you've passed a reference to ::ping instead of calling ping() - in this case, because the endpoint hasn't got any parameters, you don't need to pass it as a function reference and instead just use a
val of HttpHandler. I've updated the gist with a working version: https://gist.github.com/daviddenton/7bfeea6347b1d0e925e9ef04ac94c2a0
(And make sure you get on the kotlin slack... :smile: )
Hi - I'm just starting out so this might be obvious. I'm trying to (de)serialise things via jackson, and can't figure out how to provide my own ObjectMapper definition. I see
ConfigurableJackson takes an object mapper, but can't figure out how to use subsequent extension methods use it in eg inline fun <reified T : Any> Response.jsonPojo(pojo: T) = this.with(Body.auto<T>().toLens() of pojo)
Nice work on the lib btw, besides this it's been trivial to get started! :)
Where
Body.auto is extended via ConfigurableJackson
@thelmstedt glad to hear that you like the lib :) With regards to custom ObjectMappers, you can define your own
object like so:object MyJackson : ConfigurableJackson(ObjectMapper()
.registerModule(KotlinModule())
.configure(FAIL_ON_UNKNOWN_PROPERTIES, false)
.configure(FAIL_ON_IGNORED_PROPERTIES, false)
.configure(USE_BIG_DECIMAL_FOR_FLOATS, true)
.configure(USE_BIG_INTEGER_FOR_INTS, true)
)
Then you can just
import MyJackson.auto to activate the Jackson marshalling lenses
@thelmstedt you might also want to check out the end of this page if you're using auto-marshalling as there are a couple of Jackson-specific gotchas that can throw you: https://www.http4k.org/guide/modules/message_formats/
I managed to get jackson to stop messing with field names with
.configure(MapperFeature.USE_STD_BEAN_NAMING, true).setPropertyNamingStrategy(PropertyNamingStrategy.UPPER_CAMEL_CASE) - it requires everything to be annotated with @JsonProperty but at least it stopped messing with casing
@thelmstedt if it helps, you can also use this app to generate data class definitions for JSON messages https://http4k-data-class-gen.herokuapp.com/
We don't explicitly expose the remote IP by default - mainly because it's so unreliable in our experience. Every proxy may alter the "real" end location, or there's x-forwarded for - once again that's usecase specific - so it's probably best to do something custom for your usecase.
I think I have come across a bug with WebDriver. It seems when you submit a form with checkboxes in them the form values will be submitted irrespective of whether they are checked or not. Im not 100% sure if its wrong or not but ive done a fork, here's the commit showing what I think is wrong quii/http4k@4ddec92
Side point, it seems my intellij is configured slightly differently to whatever you have, but I cant see an editorconfig thing to make it align. Is there a way of making my thing consistent with what you want?
poke @daviddenton @s4nchez
It does look like a bug though as when i use the WebDriver and print what the server recieves it gets all form values whether they are checked but when I do it in real life it works as intended
@ttheuer GraalVM is supported out of the box for the ApacheServer or SunHttp backends (within the limits of Graal/Substrate), but we rely on quite a few of the JDK classes which aren't supplied by the Kotlin stdlib, so true multiplatform isn't available. See here for details: http4k/http4k#186
Thanks, though!
Hi, I'm working on a simple server to handle webhook requests. On one of my routes uses POST to receive the data but the bodyString() method is not working. I get the error "Exception in thread "HTTP-worker-2" java.lang.NoSuchMethodError: kotlin.io.ByteStreamsKt.readBytes(Ljava/io/InputStream;)" Anyone have experience this before or have any idea on what could be causing this?
Also make sure the Kotlin version is compatible. It may be the case you’re on a version that’s just too old
