What is this project?

This is a Play 2.3 Scala project to test Acceptto CAS service.

Live demo

Please find the demo at: TODO

Quick start

1. Install Play 2.3 (Activator)
2. git clone https://github.com/acceptto-corp/acceptto-sso-scala-client
3. cd acceptto-sso-scala-client
4. activator run
5. Open a browser and navigate to localhost:9000

Activator will automatically download all dependencies which may take some time depending on your internet connection.

Create your own client

You can use this sample and change it to meet your needs or you can create your own client from scratch. We use pac4j as CAS client and play-pac4j for Play integration.

Create a new Play project

Create a new play-scala project:

activator new

Add dependencies

Add the following dependencies:

libraryDependencies ++= Seq(
  "org.pac4j" % "play-pac4j_scala" % "1.3.0-SNAPSHOT",
  "org.pac4j" % "pac4j-cas" % "1.6.0-SNAPSHOT"
)

Configuration

Config CAS client in onStart method of Global settings class.

package controllers

import scala.concurrent.Future
import play.api._
import play.api.Play.current
import play.api.mvc._
import org.pac4j.play._
import org.pac4j.core.client._
import org.pac4j.cas.client._
import play.api.mvc.Results._

object Global extends GlobalSettings {

  override def onStart(app: Application) {
    val baseUrl = "http://localhost:9000"
    val casUrl = "https://m2m.acceptto.net/cass"

    val casClient = new CasClient()
    casClient.setCasLoginUrl(casUrl)

    val clients = new Clients(baseUrl + "/callback", casClient)
    Config.setClients(clients)
    // for test purposes : profile timeout = 60 seconds
    // Config.setProfileTimeout(60)
  }
  
}

Controller and Action

Authentication controller should inherit from ScalaController then you can use:

• getOrCreateSessionId to obtain the corresponding session
• getRedirectAction to obtain the redirection action
• getUserProfile to obtain user profile if it was available

package controllers

import play.api.mvc._
import org.pac4j.play.scala._

object Application extends ScalaController {

  def index = Action { request =>
    val newSession = getOrCreateSessionId(request)
    val urlCas = getRedirectAction(request, newSession, "CasClient", "/").getLocation()
    val profile = getUserProfile(request)
    Ok(views.html.index(profile, urlCas)).withSession(newSession)
  }
  
}

View

If the user is not authorized by Acceptto he or she will see the Authenticate with Acceptto CAS button, otherwise he or she will see the authorized profile information.

@(profile : org.pac4j.core.profile.CommonProfile, urlCas: String)

<div>
@profile match {
    case _: org.pac4j.cas.profile.CasProfile => {
        <p>
            <a href="logout">Logout</a>
        </p>
        @profile
    }
    case _ => {
        <a href="@urlCas">Authenticate with Acceptto CAS</a><br />
    }
}
</div>

Routes

The final step is to set your routes.

GET     /                           controllers.Application.index()
GET     /callback                   org.pac4j.play.CallbackController.callback()
POST    /callback                   org.pac4j.play.CallbackController.callback()
GET     /casProxyCallback           org.pac4j.play.CallbackController.callback()
POST    /casProxyCallback           org.pac4j.play.CallbackController.callback()
GET     /logout                     org.pac4j.play.CallbackController.logoutAndRedirect()
