如何使用Play Silhouette实现无状态cookie身份验证？

Question

以下链接表示您可以将CookieAuthenticator用作无状态或有状态.

http://silhouette.mohiva.com/docs/authenticator

但我看不到任何选项可以在下面的链接做出选择.

http://silhouette.mohiva.com/v3.0/docs/config-authenticators#cookieauthenticator

我已经复制了以下示例的实现.这是无国籍还是有状态的？如果有状态我如何实现无状态身份验证？

一切都是正确的。

查看CookieAuthenticator.scalagithub上的源代码：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]

因此，您只需要CookieAuthenticatorService使用定义的存储库进行创建。

在您的示例中，您可以找到一个字符串

new CookieAuthenticatorService(config, None, fingerprintGenerator, idGenerator, clock)

repository这里的参数所以None是CookieAuthenticator无状态的。
