I’m using Exposed, and I’m having trouble retrieving results from a select query..

If I get a call with destination http://127.0.0.1:8888/login/callback#access_token=xxz - how do I read

access_token

in ktor? I cannot seem to find a function that does it for me 🤔 At least not on

call.request

....

I am having issues with activating auto reload

Anyone having the same problem?

Unable to resolve dependency for ':common@debug/compileClasspath': Could not resolve io.ktor:ktor-client-ios:1.3.0.

does anyone use any swagger/openapi implementation where the documentation is derived from their ktor code? I know I looked it up a year or so ago but at that point it seemed quite early days

i have a question regarding uploading files using the Apache http client. i do a simple submitFormWithBinaryData (that's the code https://gist.github.com/bitkid/e49c12c63cc4277a6139d3992a16ecb8) in multiple upload coroutines and the weird thing is .. it never gets to the log message. on the server side i see that the server returns status code 409 (conflict) which is correct but it never makes it to that log line and it just blocks in that call. any ideas?

Question re: Ktor / Client with curl : I'm trying to build a simple client that does an HTTP request .. in IntelliJ. Getting the compiler error: "... cannot find -lcurl" . What's the easiest way to add this dependency ? Can I even do this in IntelliJ or do I need CLion to compile lcurl?

Hey all, any road map for java >= 9 support? This is slowly starting to become a real issue for us. If not even an official word is getting out that this is getting prioritized this year, then most likely 2 of our teams will be forced to switch to another framework .. which would be a shame since we really like ktor ❤️

hey! any ideas why idea complains about this code when reading multipart (BlockingMethodInNonBlockingContext)? it seems it's ok to do

part.streamProvider().reader() // do some stuff with the reader

but it's not ok to do

GZIPInputStream(part.streamProvider().buffered()).reader()

my expectation was that wrapping a stream should not be blocking or?

Hi, I’d like to custom my Ktor response pipeline to add 2 headers, one for the time it takes for the app to process the request and send the response and another one to handle etag response header transparently. I tried to create a Feature, try some interceptors, ... but I failed to find a phase where the response is processed but I am still able to add headers to the response. Often I get this error :

java.lang.UnsupportedOperationException: Headers can no longer be set because response was already completed

. I suppose it’s too late. So I was wandering if it is possible to have a phase where the Request is processed, the response is ready but I’m still able to modify the response to add some headers.

hey! when creating my fat-jar and then docker-images the way the documentation suggests, i'm also including the full application.conf and all resources in my fat-jar. Is there a way to build my server such that i can mount these config-files in a volume, making them accessible and changable without needing to rebuild the server?

simple question. With ktor-oauth, does HttpClient need to be

Apache

? It doesn't seem to want to accept

Tomcat

, but I don't want to run two applications servers just to use oauth.

Hello all. How do i format the date using jackson? I tried :

install(ContentNegotiation) {
    jackson {
        registerModule(JodaModule())
        dateFormat = DateFormat.getDateInstance(3)
        enable(SerializationFeature.INDENT_OUTPUT)
    }
}

but my json was like:

"date": {
      "year": 2020,
      "month": "JANUARY",
      "monthValue": 1,
      "dayOfMonth": 25,
      "chronology": {
        "id": "ISO",
        "calendarType": "iso8601"
      },

And what I wanted

"date": "2020/01/25"

Hi everyone! I’m trying to build a small REST API with Ktor and I’m trying to connect to a Google Cloud PostgreSQL After almost an entire day trying different things, I didn’t get it working At first, I thought the problem might be related to not using the right url and driver when connecting the Database with the Expose library (I tried different urls and none of them worked). Since Google has samples relying on Hikari to get a connection pool working, I also tried it with no luck. I think the problem might be related to the fact that I’m deploying the Ktor backend using app engine (via app engine gradle plugin), which relies on:

<servlet-class>io.ktor.server.servlet.ServletApplicationEngine</servlet-class>

and I think the Driver used by Cloud PostgreSQL might be different than the one needed? I’m not sure if what I’m saying makes sense but I’m getting crazy trying to make this work. Has anyone deployed Ktor on Google Cloud that also connects to an external database? Is it recommended? I guess the other alternative is using h2 and have a local database, but then looking at data I guess it becomes more complicated, doesn’t it? I’m quite new to the backend world, so any suggestions are more than appreciated.

❓ Does anybody invoke client's

HttpSend.intercept

function? We are going to break it's signature (only source compatibility, not binary) in 1.3.1 so want to know if anybody cares?

Has anyone here used the ktorClient together with mockk to verify? What I am doing right now is to setup a 200-always mock:

private fun createMockedHttpClient(): HttpClient {
    return HttpClient(MockEngine) {
        engine {
            addHandler { request ->
                respond("hej")
            }
        }
    }
}

and then I try to coVerify (a function from mockk) that calls were made towards the mock

coVerify(exactly = 10) { <http://httpClient.post|httpClient.post>("<http://localhost:8081>") }

but what I get is

Missing calls inside verify { ... } block.

I installed the Logging feature on an

HttpClient

with

LogLevel.ALL

, and it only seems to log requests, not responses, which doesn't make sense to me. is that the intended behavior?

HttpResponse.readText

is causing an exception with K/N: mutation attempt of frozen kotlin.collections.HashMap@3253bdb8

is it possible to use

call.respondTextWriter

together with http content compression? so basically that it writes back a chunked gzip stream.

it’s a bit annoying though that it has to be inserted in this way, since the AuthenticatePhase only exists within routes of the application that are authenticated, so you end up repeating yourself

How does authentication work with Ktor? I've set up oauth, but whenever I navigate to a protected route (protected with

authenticate {}

, it doesn't redirect me to the login page. I can't find any resources that indicate how you're supposed to accomplish this though.

Hey guys.. what’s the state of iOS websockets?

Do you know if is there any bandwith throttling system in ktor, in order to limit bandwidth from the client?

anyone know anything about route interception in ktor? Can I intercept a route, modify the request, then sent it on its merry way down to the normal routing coroutine?

it looks like

TestEngine

doesn't handle any HTTP. i'd like to have a super simple/lightweight embedded server for test purposes, to test my platform-specific HTTP clients. is there a recommended way to do this?

How can I set a timeout for a specific request? A colleague of mine tried doing the request inside kotlinx.coroutine’s

withTimeout

function, but all hell broke loose. 😅

For some reason sometimes my ktor http client (using Apache) gets stuck (no matter what request I do, it just timeouts) after a while the pending requests are executed. What I'm thinking it is happening is that it is queueing requests instead of executing them... how can I change how many parallel requests can I execute with the same client instance? (unless if I should create a new http client every time... but I don't think this is needed, right?)

@e5l I stumbled on a file where you have done some work https://github.com/ktorio/ktor/blob/master/ktor-client/ktor-client-mock/jvm/test/io/ktor/client/tests/mock/MockEngineExtendedTests.kt 🙂 Do you happen to know if the MockEngine is thread safe? I'm seeing some flaky test where I fire of 10 concurrent requests towards the a mocked httpClient

mockEngineConfig.addHandler { request ->
    respondOk()
}
ktorMockEngine = MockEngine(mockEngineConfig)
val httpClient = HttpClient(ktorMockEngine)

// fire off 10 concurrent requests, ackording to the logs all of them are sent but I end up with
Assertions.assertThat(ktorMockEngine.requestHistory.size).isEqualTo(10)
Expecting:
 <8>
to be equal to:
 <10>

getting

xcrun: error: unable to find utility "xcodebuild", not a developer tool or in PATH

while running

gradle clean check.

What am I missing? I want to run tests in

ktor-client-tests

.
