Rack::OpenID

Provides a more HTTPish API around the ruby-openid library.

Usage

You trigger an OpenID request similar to HTTP authentication. From your app, return a "401 Unauthorized" and a "WWW-Authenticate" header with the identifier you would like to validate.

On competition, the OpenID response is automatically verified and assigned to env.

  MyApp = lambda { |env|
    if resp = env["rack.openid.response"]
      case resp.status
      when :success
        ...
      when :failure
        ...
    else
      [401, {"WWW-Authenticate" => 'OpenID identifier="http://example.com/"'}, []]
    end
  }

  use Rack::OpenID
  run MyApp
