Provides simple authentication via OAuth. Supported providers: Facebook, Google, Github, Linkedin and Twitter.
See demo application running in http://play-simple-auth.pyppe.fi (source code in Pyppe/play-simple-auth-example.git)
libraryDependencies ++= Seq(
ws, // play-simple-auth uses play-ws as a provided dependency
"fi.pyppe" %% "play-simple-auth" % "1.0"
)For example:
import fi.pyppe.simpleauth.{Auth, UserResponse}
// Implicits we need:
import play.api.Play.current
import scala.concurrent.ExecutionContext.Implicits.global
object Application extends Controller {
def authenticate(provider: String) = Action.async { implicit req =>
Auth.initialize(provider) // returns Future[Result]; concretely a redirect to given provider
}
def authenticateCallback(provider: String) = Action.async { implicit req =>
Auth.callback(provider) { case UserResponse(user, userJson) =>
// Do anything you want with the user. Typically save/update to DB, and set a session.
// We will also provider the userJson JsValue for any specific needs.
val internalUserId = DB.insertOrUpdate(user) // imaginary save
Redirect("/").withSession("user.id" -> internalUserId, "user.name" -> user.name)
}
}
}FYI: The signatures for the above-mentioned functions, and the UserResponse model, are as follows:
def initialize(provider: String)
(implicit app: Application, ec: ExecutionContext, req: Request[_]): Future[Result]
def callback(provider: String)(handle: UserResponse => Result)
(implicit app: Application, ec: ExecutionContext, req: Request[_]): Future[Result]
case class Identity(userId: String, provider: String) // provider, such as "facebook", or "twitter"
case class User(identity: Identity, name: String, email: Option[String], image: Option[String])
case class UserResponse(user: User, json: JsValue)For example:
GET /authenticate/:provider controllers.Application.authenticate(provider: String)
GET /authenticate/:provider/callback controllers.Application.authenticateCallback(provider: String)
simple-auth {
# Relative or absolute callback uri (same as you have defined in routes file)
redirectUri = "/authenticate/:provider/callback"
