Spotted a typo in CONTRIBUTING.md:

sudo apt-get libcurl

E: Invalid operation libcurl

https://github.com/ktorio/ktor/blob/main/CONTRIBUTING.md?plain=1#L43 Happy to make a PR to fix if you let me know the intention.

sudo apt-get install libcurl-dev

will at least suggest some candidates? (I am on Ubuntu 20.04)

How I can legalize

Can I intercept a request before it's even sent and simulate the response? The use case is, our token is killed after a while and we want to refresh the token, without getting an unauthorized response from server. If the mentioned time is elapsed, client should know it and refresh the token automatically. I've added what I've tried below:

Hi all, when using Ktor, how can i log

request Body

?

Does Ktor support JPA ？

Hi, do you know how to set up proxy with authentication for ktor client using CIO engine on jvm. In documentation there is only this and no further details. "Proxy authentication and authorization are engine specific and should be handled by the user manually."

Hey guys! Is there a better way to receive a UTF-8 String from a post request than

call.receive<ByteArray>().toString(Charsets.UTF_8)

? I'm aware that

call.receiveText()

exists but we had some encoding issues after receiving a request containing a "Fullwidth Colon" (U+FF1A).

hello all! I was looking at the change log of ktor 2.0.0-beta1, and I’ve noticed that there’s XML support for the client: • https://github.com/ktorio/ktor/commit/0acc7080d40b1978c62e39be20470ae971417bde If I’m not mistaken, the library to import should be this one, right?

implementation("io.ktor:ktor-serialization-kotlinx-xml:2.0.0-beta-1")

However, it seems that I’m unable to use it at the moment - no classes found - at Multiplatform level (Kotlin 1.6.10). Is there something that I might be missing?

Is it possible to go get inner types with

ContentNegotiation

before passing it to

Kotlin Serialization

? In

commonMain

probably with reflection can be done but I am not finding a way to transform from

Type

,

KType

or

KClass

to to an inner type in KMP (KTOR 2.0.0)

Hi, on ktor

1.x

we could do

<http://client.post|client.post><MyResponseType>(""){}

but it

2.x

we can’t specify the return type directly?

Hi, what is the difference between

<http://httpclient.ws|httpclient.ws>()

and

httpclient.websocket()?

Hello guys, I am new to Ktor and the documentation seems to fall a bit short for me could anyone give me advice or resources to fix my issue? Thank you https://stackoverflow.com/questions/70872686/project-fatjar-not-found-in-root-project

Hi guys, Has anybody else troubles trying to include the "io.ktor:ktor-client-okhttp:2.0.0-beta-1" dependency? It just could not resolve although I've included google an maven Central repository

I created a ticket for an issue I just encountered : https://youtrack.jetbrains.com/issue/KTOR-3756

Hello guys, I'd like to setup CORS in Ktor server to match every of our product, which would be xxx.ourname.com and xxx.ourname.pl. I cannot find any way to set CORS by regex / predicate, only hardcoded strings. How can I do it?

how to read deserialized incoming messages continuously ? or as a flow in

ktor 2.x

? Should we read in a

while(true){}

client.wss() {
   while (true) {
      val customer = receiveDeserialized<Customer>()
   }
}

Is anyone here using Ktor backend to serve and consume gRPC endpoints?

the new APIs for creating plugins are only for server or there are for client too?

I am trying to get the

converters

in my plugin via

scope.pluginOrNull(ContentNegotiation)

, but they are internal, is it possible to get them in another way?

Is there a way to make the trailing

/

in routes optional? For example I want both

localhost/test

and

localhost/test/

to work.

How to use raw socket in common source set after update to 2.x version?

I'm trying to create an Android App which will communicate with Ktor server. I have successfully established a session with those two. And everything seems to work fine. On my Android app I've implemented One Tap sign in with Google, so whenever a user is authenticated, I receive a TOKEN which I'm sending to my Ktor server for verification. After it is successfully verified, I'm then saving users credentials on the server. For the session storage I'm using "directorySessionStorage". There's just one thing that's troubling me right now, and I'm hitting the wall. So whenever I launch my Android App, I'm signing in and immediately starting a NEW session with Ktor server. The only problem is, that the OLD session is not deleted even after a NEW one was created. Now I can remove that OLD SESSION if the user clicks SIGN OUT button in my Android app explicitly. However if the user just closes the app and launch it again without clicking SIGN OUT button, then that OLD SESSION will not be deleted, and a NEW one will be created, with new app launch. That way I'm seeing new session on my server directory every time a same USER launches the app again without SIGNING OUT explicitly. I don't want that, I want to remove the OLD SESSION, whenever a NEW one is created for that same USER. I'm not sure about the actual logic which needs to be implemented for that, can someone point me in the right direction? 🤔 Or is there any way that I can manually set the time limit on a session?

I'm using ktor on android and using it over a Wifi connection works fine but over mobile data a simple GET request returning json takes 10+ seconds (I measured 10mbit/s). Is that somehow my fault?

FEEDBACK NEEDED Folks, 2.0 is around the corner, and we are polishing up the last of our work on the new version. As you may be aware, we’re going to introduce a new API for writing custom plugins that is fluent and easy to use (you can read more about here https://ktor.io/docs/eap/custom-plugins.html) We’ve made a new plugin API to extend the existing one with the same types.

val DataTransformationPlugin = createApplicationPlugin(name = "DataTransformationPlugin", ::Config) {
    // ...
}

It turns out that if the library mode is enabled, it becomes a bit more complicated to read because of the type:

public val DataTransformationPlugin: ApplicationPlugin<Application, Config, PluginInstance> = createApplicationPlugin(name = "DataTransformationPlugin", ::Config) {
}

where Application and PluginInstance are fixed. We’re thinking about several options on how we can solve this: First option Drop obsolete generic parameters from

ApplicationPlugin

and keep it as

ApplicationPlugin<Config>

We need to introduce

_NAME_ApplicationPlugin<Application, Config, PluginInstance>

replacement for existing plugins, so it will be a breaking change.

public val DataTransformationPlugin: ApplicationPlugin<Config> = createApplicationPlugin(name = "DataTransformationPlugin", ::Config) {    // ...
}

Second Option Introduce typealias

_NAME_<Config>

and keep

ApplicationPlugin

as it is.

public val DataTransformationPlugin: NAME<Config> = createApplicationPlugin(name = "DataTransformationPlugin", ::Config) {
    // ...
}

Third Option Keep

ApplicationPlugin<Application, Config, Instance>

as it is. The problem with introducing NAME is precisely what we could call something that actually already has a name, i.e. ApplicationPlugin. Anything along the lines of “Default”, “Simple” or similar incorrectly could lead to the wrong assumptions. What are your thoughts on this?

hey folks, does ktor provide some client-side compression out of the box? KTOR-1199 makes me think it does not 😞

I'm trying to write unit tests for a post request but I'm having problems with the serialization:

Fail to serialize body. Content has type: class .models.NewWord, but OutgoingContent expected.
java.lang.IllegalStateException: Fail to serialize body. Content has type: class .models.NewWord, but OutgoingContent expected.
If you expect serialized body, please check that you have installed the corresponding plugin(like `ContentNegotiation`) and set `Content-Type` header.

My test according to the docs (2.0.0 btw) :

testApplication {
                val c = createClient {
                    install(ContentNegotiation) {
                        json()
                    }
                }
                val r = c.post("/word") {
                    contentType(ContentType.Application.Json)
                    setBody(NewWord("a", "b", "c"))
                }
            }

I also tried header() instead of contentType() but doesn't work either

header(HttpHeaders.ContentType, ContentType.Application.Json.toString())

the NewWord class is Serializable ofc. what am I missing?

Hey folks, I was wondering if there's an “official” way of measuring and logging response times in ktor? I know there's micro meter and dropwizard registry integration but that doesn't appear to include the response time out of the box?

I noticed that Ktor client only supports x64 Desktop targets. Is there a way to use it with macosArm64 for M1 Macs?

2: When using ktor to do multipart posts, can you do that without a content-length on each section?
