anyone can tell me where the name ktor comes from? i m giving a talk about it an i asked myself + is there something like a roadmap, couldn't find any...

Hello every one. I have a simple problem but don’t know how to solve it. When I try accessing an endpoint closed by authorization with an expired token, I need to update it using the refresh token and repeat the request. How to add something like an interceptor to the my httpClient? Example code for request:

val httpClient = HttpClient()

GlobalScope.launch(ApplicationDispatcher) {
    try {
        val url = servUrl
        val json = httpClient.get<String>{
            header("Authorization", "Bearer " + Token.getAccessToken())
            url(url)
        }

        success(json)
    } catch (ex: Exception){
        failure(ex)
    }

I would really appreciate any advice. I’m new at ktor and kotlin

Hi, how do I tell Ktor client to ignore unknown fields when deserializing to an instace of a dataclass with JacksonSerializer?

With Kotlin 1.3.50 and its Native ready

typeof

function, would it now be possible to update KotlinxSerializer to automatically fetch the serializer? So we could get rid of mapping every used serializer for a class

Does anyone know if there is a way to have an endpoint responds differently depending on if a request is authenticated or not?

Does anyone know how to add an intercepter after the authentication feature? Need it for an custom Authorization feature

How does Ktor server (specifically Netty, but in general) behave when the client disconnects, either while still reading the request from it or when writing a response back? Is this something that we have to or can handle? Does the request get cancelled? Is this documented anywhere?

is there an event thrown when server is actually started?

How do I use compression with ktor client? I added an "Accept-Encoding: gzip, deflate" header to my requests, and now the responses I get are compressed. How do I make ktor decompress them?

hi! how can i handle a cancelled request? especially cancel coroutine methods called within a request?

Hi guys, I have a question regarding ETags. I added the ConditionalHeaders feature, but I don't understand how it is supposed to work. From what I read in the class, it reads LastModified and ETag headers provided in the request and determines if a 304 must be returned or not. What I don't understand is to what the provided ETag is compared to. Where should I tell Ktor that this resources corresponds to this ETag ? Thanks

gson printing date like this

is there any way to exclude time when data type is Date

I am currently struggling with

InputStreamAsInput

. Current implementation seems to be bugged: 1) if I work with dynamic stream like the one I get from socket, it won't work since if input is empty, the input terminates. The input could be empty now, but not empty in the next moment. As a result I can't reliably convert socket input into

Input

2) It uses internal

ByteArray

pool and external

IOBuffer

pool, but sizes of those buffers are not synchronized. If someone would use non-default

IOBuffer

, It will probably break things.

is there an ktor exporter for dropwizard metrics which adds them as a endpoint? so i can query /metrics

I'm not sure if this is intended behavior, but I'm having trouble with basic authentication and route interception with Ktor. When I set up a basic authentication provider and put a simple

get

handler inside an

authenticate

block, I'll be prompted for credentials when I try to access the route, so once the

get

handler starts being executed, I can access the

UserIdPrincipal

and start finding data associated with the account. However, I now want to expand my

authenticate

block to include multiple routes, so I thought I could handle the initial processing of the principal/account inside an

intercept

block. Yet, when I try to do this, I am not prompted for my credentials and therefore the

UserIdPrincipal

inside the interceptor is null. How can I get Ktor to prompt me for my credentials from within a route interceptor inside an

authenticate

block?

Hi folks, a few months ago I've asked about how to get the hostname/port and @cy was kind enough to point me out that it's not possible. I have a similar question again, this time I need to find a way to simulate the same behavior as one would have if running a Servlet and using

getRequestUrl + getQueryString

, I know how to obtain the path of a given

route

, and the query string, it's also possible to find the

host

, but I could not find a way to determine the full original request as in

<scheme://host:<port>/path?query>

Is it possible (even without port for now, at least scheme would be nice to have)

Hey 🙂 Is there an example somewhere how to use the https://github.com/ktorio/ktor-clients/tree/master/ktor-client-redis ? @e5l

Hey folks, I'm writing a feature and I have two intercept phases, one before request is processed and other after response is written, I'm using

pipeline.insertPhaseBefore(ApplicationCallPipeline.Monitoring, phase)

and

pipeline.sendPipeline.insertPhaseAfter(ApplicationSendPipeline.After, postSendPhase)

specifically. Now, when I access the

ApplicationCall

request

and

response

is there a way to find the content-length of each? Sorry but it was not clear via the base classes how one would access that information. Thank you

Sorry for the abuse today folks, but is it possible to add request headers to a ApplicationRequest object? Here's my problem, I'm using an interceptor to add headers to the call, however the target method that receives the payload is outside of my control:

override fun put(carrier: ApplicationRequest?, key: String?, value: String?) {

        }

I tried using

HttpClient

but it's unable to find the reference. If I start typeing

import io.ktor.client

it can't find it either.

Hi all! I have a theoretical question. I want to send files from multiplatform client to serverver. I saw an example.

val result = <http://client.post|client.post><HttpResponse>("<http://127.0.0.1:$port/handler>") {
                    body = MultiPartContent.build {
                        add("user", "myuser")
                        add("password", "password")
                        add("file", byteArrayOf(1, 2, 3, 4), filename = "binary.bin")
                    }
                }

But what will doing if file is big? ByteArraySize could not be more than free RAM. How to send file from IOS and Android to multiplatform without out of memory errors?

What's the best way to send objects from a server via some interchange format (Json/Yaml/etc.) with websockets? Should I just serialize the object, then send the raw string/binary data via the associated Frame?

Is performance of ktor being tracked across versions? I ask because we have been running an old pre 1.0 version of ktor and some time ago we tried to update to 1.2.3 but saw our cpu usage double. Both running on the Jetty engine. Only difference is that we also run an older exposed version with the older ktor due to the shared coroutines dependency. Assuming ktor was 10% of our workload then that means the new version would have regressed 10x in performance which seems a bit unbelievable.

Is there a way to use the new

1.3.0-beta-1

release from gradle? It isn't published on maven central or jcenter yet but I need the ktor client proxy support. Is there another repo I can add to my gradle file that has it?

how would you guys structure your REST endpoints with ktor and locationsAPI when the same object can be retrieved by different keys? so i have as an example /api/articles/{id} (id is an UUID) but the same article can be fetched by it's unique name. would you prefer something like /api/articles/by-name/{name} or /api/articles/{name}/by-name or some kind of "polymorphism" where there is a manual check if the parameter is a UUID or a name?

anybody has some experience with react and ktor? or some other frameworks or technologies for people like me who don’t really know JS?
