ScalaJ-HTTP examples: GET, POST, handling redirects

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.

Scala: How to download and process XML data (such as an RSS feed)

I was looking for a good way to access XML resources (like RSS feeds) in Scala, and I currently like the idea of using ScalaJ-HTTP to access the URL and download the XML content, and then using the Scala XML library to process the XML string I download from the URL.

This example Scala program shows my current approach:

Processing HTTP response headers with a ScalaJ-HTTP web client

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("")
        .timeout(connTimeoutMs = 2000, readTimeoutMs = 5000)
    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.
