Hi folks. I'm playing around with ktor. I'm trying to write some integration tests for my REST resource that accepts JSON content. Right now I do it like in the snippet and everything is working. As you can see I have to "manually" serialize data object to JSON (

mapper.writeValue...

) and set it as a body for the request. Is there any nicer way to do this in integration tests and just provide and object that would be then later on automatically serialized by test framework??

Hi, I’m using Ktor Client and MockEngine as per https://ktor.io/clients/http-client/testing.html. I’d like to check the request body that is being generated. How can I get the full body? I’ve tried request.body.toString() but that returns a concatenated version.

I am writing a CMS in Kotlin that uses DSLs to produce pages (Kotlinx). I need to add authentication for the administrative side of things and to create custom content for each user. Any ideas of a good fit for Ktor?

Uhm, why has the list of headers allowed by default for CORS requests been reduced in a patch update of Ktor? That caused quite some unexpected CORS issues which took time to solve…

Hey guys, sorry if this has been asked before. I'm learning ktor and trying to set up signup/login functionality. I have the setup working and want to send a confirmation email from the server to the user's provided email, which the user can click and it opens a

Your email is confirmed

webpage, and sends a request to the server about the confirmation. How do I do that? Can someone link me to some docs or blogs. Thanks!

Hello, there is way to protect a route with an API-KEY header?

I find the routing in ktor to be less clear than I like. Coming from the play framework, I may be spoiled by the very straightforward routes file over there. Are there any tricks I should know about that could ease my life here? (A 200-endpoint routes file actually is no problem for a human eye to parse in the Play framework, but reading the same amount of endpoints from a routing {} DSL in ktor is less so ...)

is there somewhere an example for parallel file upload with ktor client?

Is there any working example of REST API application with ktor and swagger?

is it possible to ignore SSL certificate error when using the Ktor IOS httpClient?

Hi guys, I am looking for any info regarding Open Tracing implementation in Ktor. I searched and found a few personal initiatives but nothing really reusable. Is there a plan to implement such a thing (getting current trace context in servers and propagating it in clients) ? How would you implement it if it does not exist ? Thanks

Hello, iam starting with K-Tor , i have build a few endpoints that i can access from browser on my machine, from emulator browser via

<http://10.0.2.2:8080/>....

, but when iam trying to get the data from android app via

client.call("<http://10.0.2.2:8080/....>")

i get

java.net.ConnectException: Failed to connect to localhost/127.0.0.1:80

any ideas what might be wrong?

it seems like the official documentation is bad

The kotlinx serializer was not able to parse this, due to the double precision I suspect: https://api.coincap.io/v2/assets?search=eth @e5l

What's the proper way to write the hocon configuration file, configure production server based on an external file with a modified data, and also use a local file to run in intellij with autoreloading? Whatever I do, it doesn't work, any working example would be great.

I really stuck with this: I need to integrate flyway with the ktor and a custom application.conf file. I have my database connection configured in the application.conf, so I need to have it also use in the flyway when applying migrations... and the place where the conf file is read changes, on my machine is resources/application.conf, on production, who knows, it will be passed as an argument. It looks like a normal configuration, however, it's not really easy to do it.

Can you use Locations in a common module so that they can also be used by a Ktor client directly, or is it planned? It would be cool to be able to do things like

httpClient.get<SearchResponse>(SearchLocation("myQuery"))

@Magno Junior Hey, here is my proof of concept how wiring of the Flyway with the ktor config file could look like. I used the libraries I'm going to use in my real project. https://github.com/szymonlipinski/ktor-flyway

I've switched out Netty for CIO as the Ktor server to see if the performance would be better, but it seems much worse. Is CIO supposed to outperform Netty now or at some point or can it be tweaked to do that? On Netty, my throughput is about 38,000 requests per minute with 2.5 seconds per request. On CIO it's only about 21,000 and each request takes almost 5 seconds

Hello everybody! I have a question as a newby. I’d like to implement on ktor 2 endpoint: one authenticated and one not, but with the same endpoint Something like authenticate(“jwt”) { get(“hello”) { call.respond(“Authenticated”) } } get(“hello”) { call.respond(“Public”) } The above is of course not working. Is there a way to achieve this?

@cy @orangy @e5l You guys still want me to use the JetBrains Security email to report a vulnerability or do you guys want to give the new GitHub Security Advisories process a spin? https://github.com/ktorio/ktor/security/advisories

i am trying to read a csv file from a multipart request and somehow it behaves weird. when i do

for (line in part.streamProvider().reader().readLines())

it fails with "Underlying input stream returned zero bytes" but when i do

for (line in ByteArrayInputStream(part.streamProvider().readAllBytes()).reader().readLines())

it works as expected. the weird part is when i run "unix2dos file" before uploading it, it works also with the first bit of code. do i need some content type headers or something like this? reading the file locally also works with the first part, so something along the lines

for(line in File("bla").reader().readLines())

When looking to the generated trace in the first case the

/api

isn't prepend to the other routes as I fought it would, instead ktor try to match /api or /foo or /baz. Is there a way to mutualize a part of a route without adding it in every Routing ? It's quite redundant to put the

/api

in every Routing file that I might create. Also in my web.xml I tried to put

/api

in the url-pattern, but ktor doesn't seems to base its matching on it and try to work from

/

instead.

I want to run ktor Server in an Android App. I heard it is possible. But the Problem is i have to use tls. Can i also Provider a certificate ?

what's the fastest, most efficient way to write big string responses with ktor server netty engine (>200MB)?

Hey all 👋 - new to ktor and kotlin. Struggling to find a way to run a REPL that has my ktor (really

build.gradle.kts

I suppose) environment loaded. Also open to someone giving me a slap and explaining why this is not a necessary/useful part of your workflow (I'm coming from Rails/Phoenix worlds where this is commonplace).

Hey everyone! Is there a way to access the Principal instance of an authenticated call, outside the route definition?
