Put a link to your config/warden in your config.ru
require File.dirname(__FILE__) + '/config/warden'
Read the warden readme. Or look right in the lib/warden.rb
I put
Warden.test_mode!
in place of the env call at the /test path and get a nice blank page at
http://localhost:9292/test
Some bloggers have stated that there isn't a lot of documentation for warden but I disagree. There is a whole wiki. see https://github.com/hassox/warden/wiki
Take it slow and find out how to use middleware in Rack. Here's a very good article https://blog.engineyard.com/2015/understanding-rack-apps-and-middleware
I think maybe you might want to start out with tests as I found a good example and you could use it with your app.
ENV['RACK_ENV'] = 'test'
require 'test/unit'
require 'rack/test'
require File.dirname(__FILE__) + '/web'
class AuthenticationTest < Test::Unit::TestCase
include Rack::Test::Methods
def app
WardenTest #MyApp
end
def test_without_authentication
get '/protected'
assert_equal 401, last_response.status
end
def test_with_bad_credentials
authorize 'bad', 'boy'
get '/protected'
assert_equal 401, last_response.status
end
def test_with_proper_credentials
authorize 'admin', 'admin'
get '/protected'
assert_equal 200, last_response.status
assert_equal "You're welcome, authenticated client", last_response.body
end
end
Then a few routes added to your app.
helpers do
def protected!
return if authorized?
headers['WWW-Authenticate'] = 'Basic realm="Restricted Area"'
halt 401, "Not authorized\n"
end
def authorized?
@auth ||= Rack::Auth::Basic::Request.new(request.env)
@auth.provided? and @auth.basic? and @auth.credentials and
@auth.credentials == ['admin', 'admin']
end
end
get '/' do
"Everybody can see this page"
end
get '/protected' do
protected!
"You're welcome, authenticated client"
end
In my experience working with Ruby, it's always a good idea to start out with tests for any new project. I often test little pieces first though just to gain an understanding of how they work.
Once you get a better understanding of Rack, especially Rack::Builder, you can use
map '/test' do
...all the middleware needed
run App
end
and try out different configurations to see which ones work best for your needs as I'm doing while I write this.
Enjoy! ;-)
