我有如下的Akka指令结构

cors(){
   post {
      extractCredentials {
         credentials:Option[HttpCredentials] => {
            // I can successfully inspect the credentials here
         }
      }
   }
}

现在我尝试使用authenticateBasic，如

private def foo(credentials: Credentials):Option[FineAuthenticationResult] = {
      credentials match
        case Credentials.Provided(token) =>
          println(token)
          Some(ValidCredentials("foo"))
        case _ => Some(InvalidToken("foo"))
}
cors(){
   post {
       authenticateBasic(
                  realm = "Secure",
                  foo
                ) { authenticationResult =>
                  // Keep track of authorization results per channel and EVENT type
                  val additionalTags = Map(
                    "eventType" -> event.customEventType,
                    "channel" -> event.channel
                  )
                  authenticationResult match
                    case InvalidToken(message) =>
                      reject(CredentialsRejection(s"invalid token $message", additionalTags))
                    case InvalidCredentials(message) =>
                      reject(CredentialsRejection(s"invalid token $message", additionalTags))
                    case ValidCredentials(_) => complete(StatusCode.int2StatusCode(200))
                }
   }
}

foo验证码总是以“Missing credentials”（缺少凭据）的情况结束。我在测试

Postman.post(uri = "/path/path",
        channel = Some("a_channel"),
        eventType = Some("a-request")) ~>
        addCredentials(getValidToken) ~>
        routes ~>
        check {
          status shouldBe StatusCodes.OK
        }

为什么使用authenticateBasic时我总是得到丢失的凭据，而使用extractCredentials时总是给我正确的凭据。
