Akka Http Client handling 'Connection: close' and 'Transfer-Encoding: chunked'

[cs...@cksworks.com]

I'm using Akka Http Client 2.4.3 to invoke an API. I suspect the combination of 'Connection: close' and 'Transfer-Encoding: chunked' causing the databytes never materialized.

The raw response from the API as captured from curl is:

HTTP/1.1 200 OK

Date: Tue, 12 Apr 2016 18:13:13 GMT

Server: Apache

Set-Cookie: <Some Cookie>; Path=/; HttpOnly

Set-Cookie: <Some Cookie>; Expires=Fri, 10-Apr-2026 18:13:13 GMT; Path=/

Pragma: no-cache

Expires: Thu, 01 Jan 1970 00:00:00 GMT

Cache-Control: no-cache, no-store, must-revalidate, private

Vary: Accept-Encoding

Connection: close

Transfer-Encoding: chunked

Content-Type: application/json;charset=UTF-8

58

{"response":{"status":"success","value":"4o093l-0qhND.....7W35fsfnX8wjpnUjPWI3zx8BDc."}}

0

I did get the response. But, unmarshalling the entity never returns. My code to retrieve the the response entity is:

akkaHttp.singleRequest(req).flatMap { lithiumResponse =>

  logger.debug(s"Response: status = ${lithiumResponse.status}")

  Unmarshal(lithiumResponse.entity).to[JsValue] map { entity =>
    logger.info(s"response entity (JSON) = $entity")
    entity.extract[String]('response / 'value)
  }

}

It never gets to the log statement.  Thanks for the help or pointer.

Nice. Thanks. Looks like 2.4.4 has that fixed and it's tagged. Waiting for that to show up on Maven Central.
