scala - Akka HTTP AuthenticationFailedRejection 原因

Question

我创建了一个指令来验证 JWT token :

  def authenticated: Directive[Unit] = optionalHeaderValueByName("Authorization")
    .flatMap[Unit] {
      case Some(token) => Jwt.decode(token, "secret", Seq(JwtAlgorithm.HS256)) match {
        case Failure(_: JwtExpirationException) =>
          // TODO the rejection handler needs to know that the token is expired.
          reject(AuthenticationFailedRejection(CredentialsRejected, HttpChallenge("JWT", None)))
        case Failure(_: JwtException) =>
          // TODO the rejection handler needs to know that the token is invalid.
          reject(AuthenticationFailedRejection(CredentialsRejected, HttpChallenge("JWT", None)))
        case Success(_) =>
          // TODO read token and validate user id
          pass
      }
      case None => reject(AuthenticationFailedRejection(CredentialsMissing, HttpChallenge("JWT", None)))
}

问题在于，它们只有两个原因:CredentialsRejected 和 CredentialsMissing。我需要能够添加额外的拒绝原因以显示 token 是否已过期。但原因都是从密封类延伸出来的，所以我无法创建自己的类..

有没有办法创建自定义原因或向 CredentialsRejected 原因添加一些数据，以便可以检查拒绝的原因？

A(相当过时，因为它与 Spray 而不是 akka-http 有关)comment对于类似于您的请求的请求是:创建您自己的拒绝，而不是使用 AuthenticationFailedRejection 来处理此问题。
