Makes it dead easy to do HTTP Token authentication.
Simple Token example:
class PostsController < ApplicationController TOKEN = "secret" before_action :authenticate, except: [ :index ] def index render plain: "Everyone can see me!" end def edit render plain: "I'm only accessible if you know the password" end private def authenticate authenticate_or_request_with_http_token do |token, options| token == TOKEN end end end
Here is a more advanced Token example where only Atom feeds and the XML API is protected by HTTP token authentication, the regular HTML interface is protected by a session approach:
class ApplicationController < ActionController::Base before_action :set_account, :authenticate protected def set_account @account = Account.find_by(url_name: request.subdomains.first) end def authenticate case request.format when Mime::XML, Mime::ATOM if user = authenticate_with_http_token { |t, o| @account.users.authenticate(t, o) } @current_user = user else request_http_token_authentication end else if session_authenticated? @current_user = @account.users.find(session[:authenticated][:user_id]) else redirect_to(login_url) and return false end end end end
In your integration tests, you can do something like this:
def test_access_granted_from_xml get( "/notes/1.xml", nil, 'HTTP_AUTHORIZATION' => ActionController::HttpAuthentication::Token.encode_credentials(users(:dhh).token) ) assert_equal 200, status end
On shared hosts, Apache sometimes doesn't pass authentication headers to FCGI instances. If your environment matches this description and you cannot authenticate, try this rule in your Apache setup:
RewriteRule ^(.*)$ dispatch.fcgi [E=X-HTTP_AUTHORIZATION:%{HTTP:Authorization},QSA,L]
