Authorizer class Null safety

A Controller that validates the Authorization header of a request.

An instance of this type will validate that the authorization information in an Authorization header is sufficient to access the next controller in the channel.

For each request, this controller parses the authorization header, validates it with an AuthValidator and then create an Authorization object if successful. The Request keeps a reference to this Authorization and is then sent to the next controller in the channel.

If either parsing or validation fails, a 401 Unauthorized response is sent and the Request is removed from the channel.

Parsing occurs according to parser. The resulting value (e.g., username and password) is sent to validator. validator verifies this value (e.g., lookup a user in the database and verify their password matches).

Usage:

    router
      .route("/protected-route")
      .link(() =>new Authorizer.bearer(authServer))
      .link(() => new ProtectedResourceController());
