extractCredentials

Signature

def extractCredentials: Directive1[Option[HttpCredentials]]

Description

Extracts the potentially present HttpCredentials provided with the request’s Authorization header, which can be then used to implement some custom authentication or authorization logic.

See Credentials and password timing attacks for details about verifying the secret.

Example

val route =
  extractCredentials { creds =>
    complete {
      creds match {
        case Some(c) => "Credentials: " + c
        case _       => "No credentials"
      }
    }
  }

// tests:
val johnsCred = BasicHttpCredentials("John", "p4ssw0rd")
Get("/") ~> addCredentials(johnsCred) ~> // adds Authorization header
  route ~> check {
    responseAs[String] shouldEqual "Credentials: Basic Sm9objpwNHNzdzByZA=="
  }

Get("/") ~> route ~> check {
  responseAs[String] shouldEqual "No credentials"
}
