- class AuthenticatedBuilder[U] extends ActionBuilder[[A]AuthenticatedRequest[A, U], AnyContent]
An authenticated action builder.
An authenticated action builder.
This can be used to create an action builder, like so:
class UserAuthenticatedBuilder (parser: BodyParser[AnyContent])(implicit ec: ExecutionContext) extends AuthenticatedBuilder[User]({ req: RequestHeader => req.session.get("user").map(User) }, parser) { @Inject() def this(parser: BodyParsers.Default)(implicit ec: ExecutionContext) = { this(parser: BodyParser[AnyContent]) } }
You can then use the authenticated builder with other action builders, i.e. to use a messagesApi with authentication, you can add:
class AuthMessagesRequest[A](val user: User, messagesApi: MessagesApi, request: Request[A]) extends MessagesRequest[A](request, messagesApi) class AuthenticatedActionBuilder(val parser: BodyParser[AnyContent], messagesApi: MessagesApi, builder: AuthenticatedBuilder[User]) (implicit val executionContext: ExecutionContext) extends ActionBuilder[AuthMessagesRequest, AnyContent] { type ResultBlock[A] = (AuthMessagesRequest[A]) => Future[Result] @Inject def this(parser: BodyParsers.Default, messagesApi: MessagesApi, builder: UserAuthenticatedBuilder)(implicit ec: ExecutionContext) = { this(parser: BodyParser[AnyContent], messagesApi, builder) } def invokeBlock[A](request: Request[A], block: ResultBlock[A]): Future[Result] = { builder.authenticate(request, { authRequest: AuthenticatedRequest[A, User] => block(new AuthMessagesRequest[A](authRequest.user, messagesApi, request)) }) } }
- class AuthenticatedRequest[+A, U] extends WrappedRequest[A]
An authenticated request

- def Authenticated[A](userinfo: (RequestHeader) => Option[A], onUnauthorized: (RequestHeader) => Result)(action: (A) => EssentialAction): EssentialAction
Wraps another action, allowing only authenticated HTTP requests.
Wraps another action, allowing only authenticated HTTP requests. Furthermore, it lets users to configure where to retrieve the user info from and what to do in case unsuccessful authentication
For example:
//in a Security trait def username(request: RequestHeader) = request.session.get("email") def onUnauthorized(request: RequestHeader) = Results.Redirect(routes.Application.login) def isAuthenticated(f: => String => Request[AnyContent] => Result) = { Authenticated(username, onUnauthorized) { user => Action(request => f(user)(request)) } } //then in a controller def index = isAuthenticated { username => implicit request => Ok("Hello " + username) }
- A
the type of the user info value (e.g.
String
if user info consists only in a user name)- userinfo
function used to retrieve the user info from the request header
- onUnauthorized
function used to generate alternative result if the user is not authenticated
- action
the action to wrap
