We use token authentication with our app. Can somebody point me to an example of how to configure the bearer section so that the auth/refresh token can be shared across more than one http client? We have two different servers (dept1.mycompany.com and dept2.mycompany.com) that use the same auth token.

Please fix docs by adding that darwin supports websockets too: https://ktor.io/docs/websocket-client.html#add_dependencies

attempting to migrate to Ktor 2: any idea what happened to

Authentication.ChallengePhase

?

Why only

headers.append

have a method with

HeaderValueWithParameters

as second parameter and other

append*

don't? If only

append

should have this, then this doc needs to be fixed: https://api.ktor.io/ktor-client/ktor-client-core/io.ktor.client.plugins/-default-request/index.html (see "usage" box).

Hi, we are trying to migrate to ktor 2.0 but we are encountering an issue about websocket deserialization. Indeed, after inspecting the problem, it seems the issue comes from the JacksonWebsocketContentConverter. We detailed the problem on youtrack. Any idea on how we can get around this issue ?

Since Ktor 2.0.0 it should be able to be compiled as a native target. Any guide or sample that does so?

📣 Ktor 2.0.1 is now available. https://ktor.io/changelog/2.0/ 📣

Is there a way to change how client query parameters in

Resource

are serialized? Now i get

<http://example.com?ids=1&ids=2|example.com?ids=1&ids=2>

, but I would want

<http://example.com?ids=[1|example.com?ids=[1>, 2]

Does anyone generate OpenApi yaml's from their Ktor endpoints ?

Hey how to get error code, error response and body through HttpResopnse in ktor?

Is there a good way to scope an

Application.configureRoutes()

-type method within a class to be able to add additional context? For example, I want to be able to fire events when a new websocket is established, so want a way to store a sort of ‘event emitter’, and therefore allow external entities to be able to subscribe to those events. I think maybe the new

Context Receivers

would handle this? But looking for another way since those are still experimental.

Hello! Is there any way to set development mode using the embeddedServer? I see instructions for EngineMain here (https://ktor.io/docs/development-mode.html) but not for the embeddedServer. Thanks!

Hello, I am trying to create a multiplatform image loading library, I use

ktor

for remote loading and

okio

for local loading(files). I want to have an interface for fetcher that returns a flow of

Loading(progress)

,

Success(something)

,

Error(throwable)

I am not sure what

something

should be to support both fetchers.

I'm currently upgrading one of my projects to ktor V2, but using the new plugin API there is no (non-internal) way to

finish()

a call from inside a

onCall

handler. Is that intended?

encountering an odd error trying out porting an existing working application (1.6.8) to ktor 2.0.1:

In the websocket example (on this page) it states that:

In this sample, the infinite loop is only exited with an exception is risen: either a ClosedReceiveChannelException or another exception.

but when I do a test with postman and hit “disconnect” on the postman side, no exception is thrown in ktor: instead the

for (frame in incoming)

loop just exits. Is this also a possible “close” behavior?

If I add -port-8080 in Run > Edit Configurations > Program arguments I get another error: “system properties: No configuration setting found for key ‘ktor’” . WTF!?

Hello, I am trying to use

ktor-client-curl

but it fails with error:

lld: error: unable to find library -lcurl

I am using

ArchLinux

and I have

curl

installed using

pacman -S curl

Running

curl

from terminal works.

is there any good pattern to do the handling of websocket messages outside the

webSocket

block? I’m trying to do something like:

webSocket("/ws") {
    val webSocketTransport = WebSocketTransport(this)
    eventHandler.newWebSocketConnected(webSocketTransport)
}

where the

WebSocketTransport

launches a coroutine to read the incoming messages:

scope.launch {
    for (msg in webSocketSession.incoming) {
        ...
    }
}

but when I try this, the websocket disconnects immediately, because it looks like it’s implemented in a way to close as soon as the passed

handler

returns. Is there any good pattern move that logic out? I did it one way where I added another channel, and the webSocket handler read messages and wrote them to that channel, and WebSocketTransport read from that channel, but was hoping to avoid having to create the intermediary.

Hi, I’ve run an issue with testing a Ktor app where the test client receives a response with status

415

when

201

is expected. Running the app and calling the same endpoint via curl works as expected, leading me to believe that I’ve done something wrong with the test client setup. Any pointers would be appreciated. Details in thread.

Any reason the first code example here uses

header(…)

and not

contentType(…)

? https://ktor.io/docs/testing.html#form-data

I’m trying to migrate to ktor 2.0 and I’m facing an issue with tests. Currently I’m using

withTestApplication

where I call

Application.module

function with some arguments like that:

withTestApplication({
    module(appModule = appModule)
}) { ... }

now we are suppose to use

testApplication

function that seemingly calls

Application.module

function automatically, so passing custom arguments seems not possible anymore and it makes testing much more difficult. Is there any way to call

Application.module

manually? Is there any workaround?

Hey 😄 , I started a multiplatform mobile library and I’m having an issue with the native/ios side, the code compiles but on the IDE looks as if the library was missing, could I ask for some help on that?

Is there a way to have the client rebuild a url when establishing a web socket connection? My company requires the token to be in the query param because browsers can't use headers for a web socket. The AuthProvider refreshes the token successfully, but then uses the same url on the retry connection, which causes it to fail with a 401 response again.

Hey o/ I wanted ot start a ktor 2.0.1 (or 2.0.0, tried both) project, but Windows Defender flags several Artifacts from the jetbrains ktor repo as trojans. Specifically it's having issues with these files for me:

C:\Users\<username>\.gradle\caches\modules-2\files-2.1\io.ktor\ktor-server-netty-jvm\2.0.1\6210e26a36285251b7822bddc484c8a4fd71569c\ktor-server-netty-jvm-2.0.1.jar

and

C:\Users\<username>\.gradle\caches\modules-2\files-2.1\io.ktor\ktor-server-auth-jvm\2.0.0\ab5f2ce194ed07ca79bf5a7c298a757b000f37b9\ktor-server-auth-jvm-2.0.0.jar

System reboots/updates seem to not solve the problem. Gradle reimports/version changes don't seem to do the trick either. Does anyone know of similar issues?

hey I'm using ktor 2.0 and am making a plugin to piggy back off the content negotiation plugin and would like to find out which content-types are installed? So far I've only been able to accomplish it using reflection but that won't fly long-term. I started with

application.pluginOrNull(ContentNegotation)

and I can see that it's installed I just can't get to it's config and registrations without reflection that I can see.

Is there a major design flaw in the websockets client api, or am i missing something? you can call

receiveDeserialized

on the

DefaultClientWebSocketSession

but sooner or later this will inevitably result in an exception: as soon a Ping or a Close frame arrives this fails. Wouldn;t you actually need something like

frame.readDeserialiing()

or similar, so you could write something like

for(frame in incoming){ 
  when(frame.frameType)  {
   FrameType.TEXT -> frame.readDeserialzied()
   FrameType.CLOSE -> return;
}
}

?

Hey guys I am working on Custom Exception in ktor. I am seeing this example. I just notice in

ResponseException

have second paramter

cachedResponseText

. Do you guys know what is

cachedResponseText

?

ResponseException(response, cachedResponseText)

Hey 👋 I’m just beginning work on exploring migrating kompendium https://github.com/bkbnio/kompendium to Ktor 2… I am currently exploring the shiny new route level plugins and am wondering, is there any way to update application plugin state with information provided from a route level plugin? Should specify, I don’t want this to be call state, I see that you can use attribute keys to share data across the call stack. This would be state that is set at the application startup, essentially using the route level plugins to feed back into the application level open api spec, allowing you to compose the spec from the individual routes
