The below link says that you can use CookieAuthenticator as stateless or stateful.
http://silhouette.mohiva.com/docs/authenticator
But I cannot see any options to make the choice at the below link.
http://silhouette.mohiva.com/v3.0/docs/config-authenticators#cookieauthenticator
I have copied the implementation for the below example. Is this stateless or stateful? If its stateful how can I implement stateless authentication?
It's all correct.
look into the CookieAuthenticator.scala source on the github: https://github.com/mohiva/play-silhouette/blob/master/silhouette/app/com/mohiva/play/silhouette/impl/authenticators/CookieAuthenticator.scala
/**
* The service that handles the cookie authenticator.
*
* @param settings The cookie settings.
* @param repository The repository to persist the authenticator. Set it to None to use a stateless approach.
* @param fingerprintGenerator The fingerprint generator implementation.
* @param idGenerator The ID generator used to create the authenticator ID.
* @param clock The clock implementation.
* @param executionContext The execution context to handle the asynchronous operations.
*/
class CookieAuthenticatorService(
settings: CookieAuthenticatorSettings,
repository: Option[AuthenticatorRepository[CookieAuthenticator]],
fingerprintGenerator: FingerprintGenerator,
idGenerator: IDGenerator,
clock: Clock)(implicit val executionContext: ExecutionContext)
extends AuthenticatorService[CookieAuthenticator]
So you just need to create CookieAuthenticatorService with the repository defined.
In your example, you can find a string
new CookieAuthenticatorService(config, None, fingerprintGenerator, idGenerator, clock)
The repository parameter here is None so CookieAuthenticator is stateless.
