akka/akka

Hi, I am using akka-http to create proxy. I have a proxy route that takes request and proxy it to some other target service and return back the response it gets.

package com.example

import akka.actor.typed.ActorSystem
import akka.actor.typed.scaladsl.Behaviors
import akka.http.scaladsl.Http
import akka.http.scaladsl.model.{ContentTypes, HttpEntity}
import akka.http.scaladsl.server.Directives._
import akka.http.scaladsl.server.Route
import akka.stream.scaladsl.Source
import akka.util.ByteString

import scala.io.StdIn
import scala.util.Random

object HttpServerStreamingRandomNumbers {


  def main(args: Array[String]): Unit = {
    implicit val actorSystem = ActorSystem(Behaviors.empty, "myproxy")
    implicit val executionContext = actorSystem.executionContext
    val route = path("proxy"){
      Route { context =>
        println(context.request.entity.contentType)
        context.complete(HttpEntity(ContentTypes.`text/plain(UTF-8)`, ""))
      }
    }
    val bindingFuture = Http().newServerAt("localhost", 9000).bind(route)
    StdIn.readLine()
    bindingFuture.flatMap(_.unbind()).onComplete(_ => actorSystem.terminate())
  }
}

when I send curl request -

curl --location --request POST 'localhost:9000/proxy' --data-raw ''

Inside route when I try to get content-type of my request, I get content-type as application/x-www-form-urlencoded
However I want that if in the request if content-type is not passed then http server should not add Content-type header. How I can achieve this?
