Akka Http Client - User-Agent header

[Marcin Gosk]

Hey guys, is it possible to set custom header ("User-Agent") for akka streams

 val connection = Http().outgoingConnection("someServer", 443)
    val request:HttpRequest = RequestBuilding.Get(s"/some/address.json")
//    I want to add header here

//    request.addHeader(HttpHeader("User-Agent","Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0)"))
    Source.single(request).via(connection.flow).runWith(Sink.head).flatMap { response =>
      response.status match {
        case status if status.isSuccess =>
          val ticker = Unmarshal(response.entity).to[Ticker]
          println(ticker)
          ticker
        case status =>
          println(s"$status error:${response.toString}")
          Future.failed(new IOException(s"Token request failed with status ${response.status} and error ${response.entity}"))
      }
    }

Hi Marcin,

the user agent string is a config property and configured here.

Cheers

Hi,

What about other custom headers: X-Forwarded-For, SOAPAction, etc? How can I add them to the request?

[André]

The RequestBuilding trait is currently only used in tests.

you can use the methods on HttpMessage with RawHeaders instead:

HttpRequest(GET, "/some/address.json")

  .withHeaders(

    RawHeader("X-Forwarded-For", ...),

    RawHeader("SOAPAction", ...),

    ...)
