I haven’t tried it yet, but if you’re interested in a Scala HTTP client, the people at softwaremill.com have sttp, and its docs are here.

You can’t always save the client
“When you can do nothing, what can you do?”
As I’ve mentioned, you’re hired to be a consultant because you’re a problem-solver, so it really hurts when you can’t help a client. It’s a tough lesson, but it’s an important one:
Despite your best efforts,
you can’t always save the client.

If you ever need some good ScalaJ-HTTP examples, see the test files in the project, including this HttpBinTest.scala file. That file currently shows a number of good ScalaJ-HTTP examples, including GET, POST, redirect examples with Scala.
See that page for a full list of examples, but for my own use, here are a few of them.

Processing HTTP response headers with a ScalaJ-HTTP web client
By Alvin Alexander. Last updated: December 18 2018
If for some reason you ever want to print out some HTTP response headers from a HEAD request when using ScalaJ-HTTP as an HTTP client, this example may help point you in the right direction:
import scalaj.http._
object TestHead extends App
{
val response: HttpResponse[String] = Http("http://www.google.com")
.method("HEAD")
.timeout(connTimeoutMs = 2000, readTimeoutMs = 5000)
.asString
for ((k,v) <- response.headers) println(s"key: $k\nvalue: $v\n")
}
I may write more about ScalaJ-HTTP in the future, but for today that’s a quick example of processing the response headers/parameters when making a HEAD request.
