hi! does ktor have url(location) function which takes x-forward-for, x-proto etc into account?

Looks as though the Ktor KotlinX Serialisation library is causing a InvalidMutablityException to be thrown.

📣 new ktor IDEA plugin has been released with experimental locations support with inspections and intentions. Please note that the minimal IDEA version is 2018.3.6. See video in the thread :thread-please:

Does Ktor offer the ability to set javascript request timeouts? I can’t seem to find it.

The

ByteReadChannel

passed as

response.content

inside a

ResponseObserver

is now cancelled after updating from Ktor Client 1.3.0 to 1.3.2, what are we supposed to do with that?

Having a problem with cross-site POST requests. I installed the

CORS

feature as per https://ktor.io/servers/features/cors.html and everything works for

GET

. However with

POST

it seems that Chrome (version 80.0.3987.106) does not send the

Origin

header, so the ktor intercept function does not reply with the

Access-Control-Allow-Origin

header as it should. If I enforce the response header through the

DefaultHeaders

feature,

POST

works but then for

GET

Chrome complains because it does send the

Origin

header there and so with

CORS

+

DefaultHeaders

feature the response header is being set twice (and Chrome doesn't like that...). Any clue how I can work around this issue without waiting for Google to fix their stuff? EDIT: Not only does Chrome not send

Origin

headers when `POST`ing by default, it also explicitly removes them when I instruct my frontend (JavaScript

fetch

) to send an

Origin

header along with the request.

Hi, if I want to make a bunch of HTTP requests at the same time, is it better to create a new HTTP client for each request or is it ok to let these request share a same client?

I am in need of KTOR crud api for 3 entities - should I hand write it

anyone using ktor with datadog? what does your setup look like?

Hi, I'm Android developer, want to develop Rest api. Can any one explain me how can i host Ktor application in aws server.

Hello, when I’m doing a get, my code breaks with a 403. I tried to add:

HttpClient{
        expectSuccess = false
        HttpResponseValidator {
            validateResponse { response ->
                println("RESP: $response")
            }
            handleResponseException { cause ->
                println("CAUSE: $cause")
            }}
        }

But my code doesnt even reach any of those, either the

validateResponse

nor the

handleResponseException

. With my other api calls, i can see them entering the

validateResponse

, but not the one that gives me a 403. Anyone can help?

Hi. In the latest versions of the ktor client HttpResponse has been deprecated. How to I replicate something like

val myResponse = client.get<HttpResponse>(getHostRequestUrl("/api/getObject"))
if (myResponse .status != HttpStatusCode.OK) {
    log.error("Issue making service request : Status Code : ${workloadResponse.status}")
}

val myObject = parseClusterListResponse(myResponse.readText())

The deprecation error says something like:

Using 'HttpResponse' is an error. Unbound streaming [HttpResponse] is deprecated. Consider using [HttpStatement] instead

But I dont think that is appropriate. Am I wrong?

Any idea why /index.html isn't served on / using static("/") and returns 404 instead ?

Hello, is it possible to handle multipart with list of multipart nested in a request ?

Hi, I'm very new to web development so this is a very noob question. I'm trying to make a page where user can upload a file, then that file is processed and user gets output file for download. I can't find any info on how to achieve that (probably because I don't know what terms to use for search). Here's pseudo code of what I'm trying to do:

fun Route.handleFile() {
    post("/handleFile") {
        call.respondTextWriter {
            appendln("Writing some output while file is being processed")
            // Handle file that will create another file for user to download
            call.respondFile(outputFile) // I know I cannot do this
        }
    }
}

Basically I want to run a long running task and show some text to the user about the progress and then after it finished that output file should be downloaded. Is that even possible to do just within ktor?

Is there an interceptable stage in which I know the HTTP status code of a response?

Sorry if this is off topic, but I have finished a hobby project with ktor which is a REST API. Now I want to make it publicly available, but I need some monitoring system / see usage graphs etc. Is there something that either integrates with ktor or is just a free API gateway in general? I want some kind of a dashboard where I can see how my ktor API is doing.

Does anyone know, how to publish a custom ktor feature?

hello guys, is ktor 1.3.2 compatible with Kotlin 1.3.71 ? https://github.com/JetBrains/kotlin/releases/tag/v1.3.71

Is it save to use

<http://io.ktor.utils.io|io.ktor.utils.io>.errors.IOException

for all network IO exceptions across platforms?

Does Ktor supports Java 13?

I have a string property "id" in my json object which i'd like to wrap in an inline class (or data class if necessary), i know i can use

@JsonValue

to make the serialization work, but what about the deserialization?

Hey friends! 🙂 I have a question regarding

HttpClient

usage. If I want to execute an API call when someone “hits” a specific endpoint, do I just need to call

<http://client.post|client.post>(…)

inside the route callback, or am I missing something? It is like the call is never executed and cancelled after the specified timeout..! Thanks in advance!

Hi all! I've just started with Kotlin and Ktor and I'm setting up a server with JWT authentication. I want the server to respond with a 401 code and a relevant message when the token is incorrect. For example, if the claim

userId

is missing then I would like to have a response saying "Claim 'userId' is missing". I don't think it's currently possible in Ktor and I would like to add it to Ktor. Can any of you offer some insight in whether (a) this is a good feature and (b) how I would go about adding this? The Java library that parses the JWT returns useful information in an exception, but this information is then discarded and an empty UnauthorizedResponse is sent. I think the solution is to add this information to the UnauthorizedResponse as a response body.

This idea is inspired by Django, which also tries to return a helpful message when there is a (client) error.

Does anyone know when ktor native will work with multithreaded coroutines? I see two github issues that mentions this problem: https://github.com/ktorio/ktor/issues/1543 https://github.com/ktorio/ktor/issues/1538

[Resolved] I'm getting a "Not started" error trying to launch a coroutine inside a Ktor call. Anyone knows what this is about?

Are there any types of streaming data types that I can get from the Client that can be safely shared and read from concurrently? I think what I’m looking for is something that will replay the already buffered content and will also properly emit to suspended functions when new content is available.

Is there a way to override a `defaultRequest`s

host

? Doing this is not working:

val httpClient = HttpClient(Android) {
        defaultRequest {
            contentType(ContentType.Application.Json)
            url {
                host = currentBuildEnvironment.defaultEndpoint
                protocol = URLProtocol.HTTPS
            }
        }
    }

//elsewhere..
fun makeRequest() = <http://httpClient.post|httpClient.post> {
    url {
        encodedPath = "/endpoint"
        host = currentBuildEnvironment.otherEndpoint
    }
    body = //etc
}

It's using

defaultEndpoint

instead of

otherEndpoint

. Am I missing something here?
