hi all, is it expected that ByteReadChannel removes newlines? If so, is there a way to preserve the newlines instead?

Hi! Could you tell me how you are reading from channel?

04/21/2022, 8:10 PM

we're trying to do something like this

OutgoingContent.WriteChannelContent() {
  override val contentType = RdfContentTypes.Turtle
  override suspend fun writeTo(channel: ByteWriteChannel) {
    call.request.receiveChannel().copyTo(channel)
}

where we want to forward the request body to another service

It should keep new lines in this case. Could you try use logging or reading body as string?

i have, and it does seem to remove newlines

encoding should be default UTF-8, so not sure what's going on

call.request.receiveChannel().readUTF8Line()

should preserve newlines as well right?

It will read line by line

ok so that is definitely concatenating lines

i'm sending an rdf turtle file, and i see all the prefixes on one line doing that

INFO  Application - @prefix rdf: <<http://www.w3.org/1999/02/22-rdf-syntax-ns#>> .@prefix rdfs: <<http://www.w3.org/2000/01/rdf-schema#>> .@prefix owl: <<http://www.w3.org/2002/07/owl#>> .@prefix xsd: <<http://www.w3.org/2001/XMLSchema#>>

where our source file looks like this

@prefix rdf: <<http://www.w3.org/1999/02/22-rdf-syntax-ns#>> .
@prefix rdfs: <<http://www.w3.org/2000/01/rdf-schema#>> .
@prefix owl: <<http://www.w3.org/2002/07/owl#>> .
@prefix xsd: <<http://www.w3.org/2001/XMLSchema#>> .

encoding is in utf-8-unix
