does anyone have an example of how would I load an

.env

variables into ktor before starting local env or running tests?

why am I unable to resolve

JsonFeature

even if I have

ktor-client-json

as a dependency? It was working at some point and now I cannot get it to work, even if I create a new project using the ktor intellij creator. Maven is just completely unable to resolve the

.json.

package.

Hello! I am using Ktor for some time now and I could say that I became pretty familiar, but there is still a thing that puzzles me 😅 What problem addresses / solves

SuspendFunctionGun

in respect to the naive implementation of

DebugPipelineExecutor

? @e5l maybe you can help me understand, as you are one of the main committers, Thank you!

Hi, I’m trying to build my project which depends on

io.ktor:ktor-client-core:2.0.0-beta-1

and i’m running into this error:

Uncaught Kotlin exception: kotlin.IllegalArgumentException: Failed to open iconv for charset ISO-8859-1 with error code 22

This is running on our Alpine Linux build server which has iconv available

echo 'foo' | iconv -f ISO-8859-1 -t ASCII

Any ideas what’s going on here?

Hi, I have a question on Ktor-Client 1.6.7 Bearer token. Is it possible to customise the condition of calling

refreshTokens

function? For example, without the

WWW-Authenticate

header? https://ktor.io/docs/auth.html#bearer

3. Specify how to obtain a new token if the old one is invalid using refreshTokens. Note that this block will be called after receiving a 401 (Unauthorized) response with the WWW-Authenticate header.

Has anyone here done ssl cert ignoring for js? I'd like to run e2e tests in my kotest kotlin js suite that uses a ktor js client to talk to some server with self signed certs 🤔

What would be the best way to decode gzipped requests in a ktor server?

Is there any advantage using nodejs over ktor for backend or every possible thing could be done using just ktor

I started a new ktor project and i’m adding sqldelight dependency but I’m getting the error:

Gradle Core Plugins (plugin is not in 'org.gradle' namespace)

The project is just a single module build ( no top level buiild.gradle.kts file) How do i fix this?

I’m trying to respond with JSON while following with these dependencies on my project . However I cannot import

Is there a library for bucket-based per-client ratelimiting? I've only found ones that have a global configuration rather than allowing specifying it per bucket (if it even had buckets)

If I want to catch all my exceptions and log them to bugsnag, or Datadog, where is the best place to do that? I was considering the

StatusPages

plugin, using the

Throwable

catch all.

install(StatusPages) {
            exception<Throwable> {
                call.respond(HttpStatusCode.InternalServerError)
            }
        }

Hi, I’m trying out Ktor and want to configure some routes with

Locations

I have a problem configuring a simple

POST

endpoint. I have the following code:

@Location("/v1/login")
class Login

post<Login> {
 ...
}

But I get 404s. If I change it to

get<Login> {…}

everything is ok. Can’t seem to find any examples using

post

and

Locations

I just created a project with Ktor but my changes are not auto reloading unless I rerun the app on IntelliJ. Is there auto-reload out of the box?

I want to Upload an image from Android to server as Binary form. the postman code is:

curl --location -g --request POST '<https://svform.herokuapp.com/createUser/{userName}/{mobileNumber}>' \

--form 'profileImage=@"/Users/akram/Documents/14_07_2020-hbtu_kanpur_20509722.jpg"'

So I write a code like this:

@OptIn(InternalAPI::class)
suspend fun creatUser(
    context : Context,
    userName: String,
    mobileNumber:String,
    image: Uri,
) = client
    .submitFormWithBinaryData<MemberEntity>(
        url = "$POST_NEW_USER/$userName/$mobileNumber",
        formData = formData {
            append(
                key = "profileImage",
                value = getBinaryFile(context = context, contentUri = image)!!
            )
        },

            ){

        onUpload { bytesSentTotal, contentLength ->
            println("Sent $bytesSentTotal bytes from $contentLength")
        }
   }

I got an error of type :

Serializer for class 'BinaryItem' is not found.

When I add the ContentType, I got another error

Header(s) [Content-Type] are controlled by the engine and cannot be set explicitly

..... Please any help ?

Hi dear community, have been messing around with Ktor and HOCON configs, I found that you can feed different application config as an argument, but is there something similar to spring boot's "active profiles"? Where you can provide multiple configs, like some main config that describes everything, and some smaller dev/other config after main one, that overrides only few things it has, without a need to duplicate all the other configuration properties between multiple configs.

What is the purpose of Ktor-cli and how do i use it?

Is there any effort by JetBrains to support graphql server out of the box with Ktor? Interested in hosting a server on iOS device.

I can't figure out how I can call Dropbox API using Ktor 1. I need to post JSON data to this endpoint: https://www.dropbox.com/developers/documentation/http/documentation#files-list_folder This does not work:

var delta: DropboxDelta = post("$DROPBOX_API_URL/files/list_folder") {
    contentType(ContentType.Application.Json)
    body = Parameters.build {
        append("path", "/")
        append("recursive", "true")
        append("include_non_downloadable_files", "false")
    }.formUrlEncode()
}

Client request(https://api.dropboxapi.com/2/files/list_folder) invalid: 400 Bad Request. Text: "Error in call to API function "files/list_folder": request body: expected object, got string" For OAuth I can use this construct:

return tokenClient.submitForm(
    url = tokenUrl,
    formParameters = Parameters.build {
        append("grant_type", "authorization_code")
        append("code", authorizationCode)
        append("client_id", clientId)
    }
)

But that does not work with list_folder Can someone share an example how to do this?

hello channel, a quick question about websockets in ktor for example in node js(socket.io), we can do something like this: socket.broadcast.to(socket).emit('event_name', JSON.stringify(data)) the event_name can be used to differentiate between event types on client side, how to do something like this in ktor? all I can see in ktor examples is that you send message as: socket.send(Frame(data)) Is there a neat way to send the event type along with the data?

hi there guys does ktor has the way (mode\interceptor arguments for configuration) how to join all logs related to request\response to one log record? or should I make it by myself as my own interceptor? not very convenient to log all(method, header, body) info separately in my case

How do i turn on development mode if I don’t have

application.conf

. Can I do it inside the

How do I clear the session cookie from the server-side?

Is there a way to easily make RSS feeds with ktor or will I have to make one myself?

Hi all. With 2.0-eap (2.0.0-eap-278), StatusPages does not seem to catch exceptions occurring during HTML DSL rendering. I saw a git commit fixing the same issue for freemarker, KTOR-343 ( git diff 18222b4e8~ 18222b4e8 ), which I don't fully understand, lacking some knowledge about the 2.0 refactoring; I was wondering if it was the same kind of problem. Also, would the Velocity plugin also be affected?

I’m reading how to serve static content with ktor. In the snippet below:

routing {

static("assets") {

files("css")

files("js")

}

}

Does

files("css")

look for the folder

css

and/or files with the extension

.css

?

What is the difference between

files

and resources ? StackOverflow question

Hey people, anyone can help me with Google JWT? So I'm building an Android app, and also there I'm authenticating my users with Google. They authenticate successfully and I get their JWT as a response. Now since I'm also using Ktor for my back-end (where I'm planning to store their profile information), I also need to verify their Google JWT token, before I can store/save their information on my server.. What's the best way to verify my users Google JWT on Ktor server? Is there any API available? 🤔

Is there a way to create a custom

CoroutineContext

that’s used for all requests? I swear there was a way to do this that I read a while ago, but I can’t find it in the documentation. If I use an Authentication provider, currently that authentication information is only stored inside the

call

. I’d like to create a custom

CoroutineContext

for each request, so that anywhere in the server that I’m in a

suspend

function, I can get the userId, instead of having to pass it through to every method call in my server.

Hi all, it looks like you can’t cash

HttpClient

with

when using

. But it looks working fine with Http ? Here is the error i am getting Kotlin multiplatform: JobCancellationException: Parent job is Completed
