__construct(string $realmName)

Parameters

Response start(Request $request, AuthenticationException $authException = null)

Returns a response that directs the user to authenticate.

This is called when an anonymous request accesses a resource that requires authentication. The job of this method is to return some response that "helps" the user start into the authentication process.

Examples:

• For a form login, you might redirect to the login page

  return new RedirectResponse('/login');

• For an API token authentication system, you return a 401 response

  return new Response('Auth header required', 401);

Parameters
