Hi! How can I send a 204 No content response without content ?

call.respond(HttpStatusCode.NoContent, Unit)

I have

{}

in the content.

I don’t think you need the second parameter there, HttpStatusCode can be sent by itself for no content

☝️ How? because there is either

ApplicationCall.respond(status: HttpStatusCode, message: Any)

or

ApplicationCall.respond(message: Any)

if you send only HttpStatusCode, the second method will be used and the status will be serialized as response content

Yes, the

respond

method doesn’t exist with only the HTTP code as parameter.

call.response.status(HttpStatusCode.NoContent)

that’s it, you just access the response object and set values which will be immediately sent to the client. https://ktor.io/docs/responses.html

Unless I'm missing something entirely, it does work with

call.respond(HttpStatusCode.NoContent)

directly - there'll be a feature somewhere checking if

message

has a type of

HttpStatusCode

and mutating the response. I'll have a dig later 🙂
