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

[Milan Hruban]

☝️ 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

[mmaillot]

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

[Matteo Mirk]

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.

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 🙂
