Rack::MicroService::SignedRequest provides support for handling MicroService signed requests in Rack compatible applications.

Add this line to your application's Gemfile:

gem 'rack-micro_service-signed_request', :require => 'rack-micro_service-signed_request'

And then execute:

$ bundle

Or install it yourself as:

$ gem install rack-micro_service-signed_request

In the config.ru

use Rack::MicroService::SignedRequest
	# Your app might support multiple MicroService instances
	# This block allows you to determine what secret to use based on the Authorization header
	secret do |auth_header_params|
		"this_should_be_the_app_secret_for_authentication_header_params"
	end
end

In config/application.rb

module ExampleApp
	class Application < Rails::Application
		config.middleware.use "Rack::MicroService::SignedRequest" do
			# Your app might support multiple MicroService instances
			# This block allows you to determine what secret to use based on the Authorization header
			secret do |auth_header_params|
				"this_should_be_the_app_secret_for_authentication_header_params"
			end
		end
	end
end

request.env['micro_service.client_id'] will be populated with add-ons client_id

request.env['micro_service.errors.signed_request'] will be populated if there was an error authenticating the signed request
