authenticateBasicAsync
Wraps the inner route with Http Basic authentication support using a given AsyncAuthenticator<T>.
Description
This variant of the authenticateBasic directive returns a Future<Optional<T>> which allows freeing up the routing
layer of Akka HTTP, freeing it for other requests. It should be used whenever an authentication is expected to take
a longer amount of time (e.g. looking up the user in a database).
In case the returned option is an empty Optional the request is rejected with a AuthenticationFailedRejection,
which by default is mapped to an 401 Unauthorized response.
Standard HTTP-based authentication which uses the WWW-Authenticate header containing challenge data and
Authorization header for receiving credentials is implemented in subclasses of HttpAuthenticator.
See Credentials and password timing attacks for details about verifying the secret.
Warning
Make sure to use basic authentication only over SSL/TLS because credentials are transferred in plaintext.
