I could see how this might get a little confusing for a deeply nested object

hi guys. has anyone tried to use log4j threadcontext with ktor?

Hello everybody! Today I have tried to resolve dependency

io.ktor:ktor-client-encoding:1.3.0

in my java-only project, but I got error. After this I have used

io.ktor:ktor-client-encoding-jvm:1.3.0

and it was successfully resolved. Is it known issue? In the jcenter you have redundant jars in package io/ktor/ktor-client-encoding/1.3.0 which, as I understand, must not be included in case if package is multiplatform-oriented

Is it possible to disable Ktor client keep-alive?

hi all, I'm really new on ktor. trying to use heroku. I am able to run the sample helloworld project locally. the problem is I'm getting the following error while deploying the project to heroku;

bash: build/install/myproject/bin/myproject: No such file or directory

I have the following line in my Procfile

web: build/install/myproject/bin/myproject

I am able to see this file in my ide. what should I use for my Procfile? Any guess would be appreciated. Thanks

The Kotlin Blog mentions that you can configure the Ios HTTP engine like this:

HttpClient(Ios) {

engine {

configureSession {

networkServiceType = NSURLNetworkServiceTypeBackground

}

}

}

But when doing that, I get the follow compile error: Unresolved reference: NSURLNetworkServiceTypeBackground I am using 1.3.0.

Is there a way to trust/ignore selfsigned/internal SSL certificates in Ktor for iOS ? https://stackoverflow.com/questions/60005195/ktor-client-ios-and-self-signed-certificate

Hello everybody..., i'm working in a presentation of Ktor for an upcoming Kotlinconf global event (just the basics of ktor), and i was wondering, does anyone knows the meaning of the word Ktor and why JetBrains name his Web Framework like that?

Hi, I'm new to Kotlin and Ktor and i'd like this basic function to run but I can't find where the issue is:

package com.example

import io.ktor.server.engine.embeddedServer
import io.ktor.server.netty.Netty
import io.ktor.routing.*

fun main() {
    embeddedServer(Netty, port = 8080){ }.start()
    routing {
        get("/") {
            call.respondText("Hello, world!", ContentType.Text.Html)
        }
    }
}

The issue i'm getting is, the routing package cannot be imported. Any assistance will be greatly appreciated.

Hey I’m using

kotlinx-serialization

with

ktor

however I’m receiving a

java.lang.NoClassDefFoundError

with

call.receive<MyModel>

. Any clue what could be wrong with the setup?

how much overhead would you think that chunked gzip encoding creates? factor 3 sounds realistic? that's what i am experiencing at least 🙂

is anyone else getting broken javascript in from the webpack bundle when using ktor 1.3.0 ?

Hi guys, is it any validation library in kotlin, like @NotBlank or @Size?

is CIO client engine still experimental?

Hello everyone! I’m having an issue with Ktor de-serializing json in a post request. I’m using

kotlinx.serialization

and the exception occurs with

call.receive<MyMode>

. I’m curious if it a similar issue is the same as @nrobi. I don’t get the

java.lang.NoClassDefFoundError

but I do get

io.ktor.features.CannotTransformContentToTypeException: Cannot transform this request's content to

. I followed the instructions in https://ktor.io/servers/features/content-negotiation/serialization-converter.html and https://ktor.io/servers/calls/requests.html. I have the correct grade entry in my build.gradle file:

implementation "io.ktor:ktor-serialization:$ktor_version"

I install the ContentNegotiator:

fun Application.module() {
    install(ContentNegotiation) {
        serialization(
            contentType = ContentType.Application.Json,
            json = Json(DefaultJsonConfiguration.copy(prettyPrint = true))
        )
    }

    val dao = DAOFacadeDatabase(Database.connect("jdbc:h2:mem:test;DB_CLOSE_DELAY=-1", driver = "org.h2.Driver"))
    val server = embeddedServer(Netty, port = 8080) {

I have my simple data class:

data class UrlMap(val id: String, val url: String, val userId: String)

The exception is thrown here:

val receive = call.receive<UrlMap>()

I follow multiple examples on website and the official Ktor documentation and I can’t get it to work. I’m using Ktor 1.3.0 with Kotlin 1.3.61. Any help would be greatly appreciated

I am working on uploading via Ktor MutliPartFormDataContent an image from MP module (File on Java and NSData on iOS). I see an Input/AbstractInput interface that appears needed to wrap the native types so Ktor can pull in the requisite data. I don’t suppose anybody has an example of implementing AbstractInput? I am trying, but it does not seem to advance past the first block. Thank you!

I have the same question for the

ktor-http

artifact. Not referenced in https://ktor.io/quickstart/artifacts.html either, and no README about it on GitHub.

Is there a support for HikariCP's setHealthCheckRegistry? I'm trying this:

Jdbi.create(HikariDataSource(HikariConfig().apply {
			username = config.property("db.username").getString()
			password = config.property("db.password").getString()
			jdbcUrl = config.property("db.jdbcUrl").getString()

			application.featureOrNull(DropwizardMetrics)?.registry?.also {
				<http://application.log.info|application.log.info>("Dropwizard metrics feature detected. Registering HikariCP metrics.")
				metricRegistry = it
				healthCheckRegistry = it
			}
		}

but getting an error:

java.lang.NoClassDefFoundError: com/codahale/metrics/health/HealthCheckRegistry

at com.zaxxer.hikari.HikariConfig.setHealthCheckRegistry(HikariConfig.java:697)

I'm looking for examples of how to combine Ktor WebSocket client with Asynchronous Flow. I have a pub/sub-like setup where I send a message to server in order to subscribe for values, but I'm completely lost on how to set this up. I can share what I have so far, but it's quite bad. I doesn't have to be with Flow, but I figured it would fit quite well here.

I'm getting `ResponseAlreadySentException`s when using a redirect. Stack trace:

io.ktor.server.engine.BaseApplicationResponse$ResponseAlreadySentException: Response has already been sent
at io.ktor.server.engine.BaseApplicationResponse.commitHeaders (BaseApplicationResponse.kt:44)
at io.ktor.server.engine.BaseApplicationResponse.respondOutgoingContent$suspendImpl (BaseApplicationResponse.kt:108)
at io.ktor.server.engine.BaseApplicationResponse.respondOutgoingContent (BaseApplicationResponse.kt)

The code generating the response is:

call.respondRedirect(signedUrl)

where

signedUrl

is a string with a URL. The redirect works - the client gets the correct result and redirects to the new path. Just wondering why there is an exception.

When I'm trying to download a "larger" file (355k) with HttpClient, it seems that it does not let me read more than 4096 bytes. What I could I be doing wrong? I am also not seeing the response logging in Logcat, just the request

Hello everyone! I'd like to modify an incoming request early in the pipeline before other features have an opportunity to see the request. I've looked through the samples and most seem to focus on modifying the response, not the request. Can anyone point me to an example of modifying an incoming request or provide some suggestions? It would be much appreciated!

Hi Team, Is there any default distributed lock implementation in ktor ?

Hello all. How do I call a suspend function in Application.kt? I have a suspend fun and when I call it, an error appears forcing to change the main function to suspend. And if I do that, I can't start the application.

Also, do you think it is better practice to call

HttpClient()

in the common code, or to

expect

the client from each platform to have more granular settings (but maybe code duplication as well?)

That error would typically be coming from the server you are calling. It is completely within it’s rights to return a 411 response
