Getting user's ip address

[razataz000]

I am wondering how to get a user's ip address from play framework and scala.

I have found this but it doesn't work:

def index = Action { implicit request =>

    val address =  request.remoteAddress

}

Do I need to import a special library at the top of the file? Thanks for you help!

[Michael Schleichardt]

No, it should work that way.

  def index = Action {  implicit request =>
    val address =  request.remoteAddress

    Logger.info("address " + address)
    Ok(address)
  }

Note that if you're using a proxy you need to set trustxforwarded=true in your conf, and make sure that the proxy supports X-Forwarded-For.

Even then it's not a guarantee that other network components don't screw about with the request, I've seen banking networks that use reverse proxy based security products with half a dozen different request headers to check in turn.

Regards

Brian

This code doesn't work. And what config file do I put the configuration in?

[Jay]

You do something simple like this

val ipAddress = request.headers.get("X-Forwarded-For") match {
      case Some(ip: String) => ip
      case None => request.remoteAddress

Also, if you are using Play head by some chance, there is now  constant for "X-Forwarded-For":

Presumably in application.conf.  I was guessing from the the source code comment [1].

There is also info on proxying at [2].

Those indicate that you shouldn't need to add code for this if you set the config variable and the remote address is in the X-Forwarded-For header.
