Hi, I'm having an issue understanding and using suspend function with dependency injection ...

class SdWsService(fileUtils: FileUtils) {
    suspend fun getXmlFile(environment: String?, filename: String): String = dbQuery(environment) {

Inside getXmlFile, I do not have access to my fileUtils ...

Any advice on implementing Cacheing with Ktor http client? struggling with CacheControl. Working with the MPP client

Is there a visual description of how the ktor client pipelines connect each other, to better know which pipeline I should intercept?

I can’t seem to use client/JsonFeature. I declared the dependency (

"io.ktor:ktor-client-json:$ktor_version"

) in my build.gradle, and I see it (can even navigate into it) in IntelliJ. But I can’t call install(JsonFeature)` . (“Unresolved Reference”) I tried the fully qualified name,

gradle clean

, and even deleting the whole

~/.gradle

folder. Nothing. Hitting “build” tells me, that client-json requires “’org.jetbrains.kotlinx:kotlinx-serialization-common:0.10.0”, but adding that to dependencies also doesn’t help. And also, it shouldn’t be that hard. Any ideas?

How can I achieve something like this with ktor routing?

fun Routing.v1() {
    route("/api/v1") {
        posts()
    }
}

I am getting

fun Routing.posts() can't be called in this context by implicit receiver

I'm having a little encoding problem here, can someone point in the right direction? I have a simple route set up that simply sends the contents of the POST body back to the client:

post("/reflect") {
    call.respondText(call.receiveText().also(::println))
}

When I send a request with special characters in it like this:

POST <http://localhost:8080/reflect>
Content-Type: text/plain

ÄÖÜäöüßẞ

It comes out as a jumbled mess:

ÃÃÃäöüÃáº

And it get's printed to the console exactly like that as well, so the problem has to be on the receiving side, not the sending side. I'm not sure where to start looking what is going wrong here.

How would I retry a request with new headers in a feature in the ktor client?

in the ktor client, we can specify

expectSuccess = false

to control whetehr an exception should be thrown if the status is >= 300. can I also have more fine-grained control out-of-the-box? E.g. allowing 404 but throwing otherwise

How can I register multiple serializers when using a class with generic type, for example:

Response<Foo>
Response<Bar>

Is there an existing way of running certificate pinning on iOS and android targets with ktor httpClient?

I should not be forced to call

.build()

on a

HttpRequestBuilder

to get the

attributes

already set on that builder

What version of Ktor should I be using with Kotlin 1.3.30?

I have been building a small http server with ktor on heroku and I have reached a point where I want to have some metrics. I'm mainely building android apps so in my world there are things like crashlytics and amplitude. can you point me to a possible solution for monitoring errors, i.e. 40*, 50*, or other non fatal issues? 😄

Hi. Where can I read more about the rationale to divide the

ApplicationCallPipeline

into the 5 phases:

Setup

,

Monitoring

,

Features

,

Call

, and

Fallback

? Namely, what are the responsibilities of the interceptors in each phase?

Since apparently routes have their own pipeline (https://ktor.io/advanced/pipeline/route.html), is it possible to install a feature on a route's pipeline? I tried doing something like

route("/foo", HttpMethod.Get) {
            install(ExampleFeature)
            handle {...}
}

However the feature appears to run for all routes.

So... what’s the current status of Ktor 1.2 with Kotlin 1.3.30 and Coroutines 1.2 and Serialization 0.11?

Is this the best way to handle deserialization of lists with the http client on the JS platform? https://stackoverflow.com/a/54714777 I see a setListMapper function but that doesn't seem to do anything.

📣 New ktor

1.1.4

released! It’s the minor release with kotlin

1.3.30

support.

I’m trying to execute the following post request but I get an exception from the coroutine with

Parent job is Completed

? Just wondering what I may be doing wrong 😕, the request seems fine from the logger

Hi, I am using .ktor and okhttp engine. And got exception certpathvalidatorexception when we tried to migrate to https, can I use ktor fot https? And if ‘yes’ where start searching to solve my issue, I think it’s because we use some like backend developers says ‘custom certificate’.

Hi. I have the following warning when building a Gradle module in an MP project

warning: this class can only be used with the compiler argument '-Xuse-experimental=kotlin.Experimental'
@UseExperimental(KtorExperimentalAPI::class)

I’m trying to use IosHttpRequestException, but adding the mentioned option in

kotlinOptions.freeCompilerArgs

seems not to work. Any suggestion to fix the warning? Thanks.

With the Http client are there alternative ways to handle WebSocket events that don't involve streaming?

Is anyone else using IntelliJ 2019.1 and the Ktor plugin? Experiencing an issue where new projects cannot be created while the plugin is active.

Has anyone experienced a "connection reset by peer" message when using SSL with Ktor Server (using Netty as the web engine) when its under a bit of load?

Does anyone know how to add OpenGraph meta tags using the HTML DSL? I need to be able to add tags such as

<meta prefix="og <http://ogp.me/ns#>" property="og:title" content="title" />

But the

META

class doesn't seem to support the

prefix

and

property

attributes. Currently I'm using

unsafe

to render the raw HTML, but I'd prefer not to.

Hi, as I had no answer, I try an other time to ask my question. Thanks for your comprehension and your help. “hi, in my API app, I’d like to decorate (sort of programming by aspect) all my request by a method to compute how long it takes to process it. I need to do some measure. Right now, I am looking at Route interception to do the job but I am quite lost on how it is working (I read the article https://ktor.io/advanced/pipeline/route.html) but sorry, I didn’t manage to make it work. Do you have any clue, hint ou may be a link on a sample ? Is it a good practice to use Route Interception to do this kind of job ?”

How can I install a feature(or `Application.intercept') only a subset of routes? For example every request to

com/foo

and

com/foo/***/***

should trigger the feature.

so before i try to use ktor-httpclient for something thats impossible.. when i try to use it on javascript i can not run it in the background because of the lack of threading correct ? so i i want to do things i have to make do with simple GET and POST requests instead of keeping open some connection and processing data in aprallel or can i do that in kotlin-js ?
