7. Custom Middleware class CurrentUserLogger < Rails::Rack::Logger protected def started_request_message(request) end end
8. Custom Middleware def started_request_message(request) 'Started %s "%s" for %s at %s %s' % [ request.request_method, request.filtered_path, request.ip, Time.now.to_default_s, by_current_user(request) ] end
9. Application.rb config.log_tags = [:subdomain,:uuid] config.middleware.swap(Rails::Rack::Logger,’CurrentUserLogger', config.log_tags)
10. config.middleware.delete(ActionDispatch::Cooki es) config.middleware.delete(ActionDispatch::Sessi on::CookieStore) config.middleware.insert_before("CurrentUserLo gger”, ActionDispatch::Session::CookieStore) config.middleware.insert_before(ActionDispatch ::Session::CookieStore, ActionDispatch::Cookies) Easy Way
11. Hard Way or My Way def by_current_user(request) read_signed_cookie(request) rescue => e "" end
12. Custom Middleware def read_signed_cookie(request) content = URI.unescape(request.cookies[“_app_session”]) key_generator = ActiveSupport::KeyGenerator.new(Rails.config.secret_key_base, iterations: 1000) key_generator = ActiveSupport::CachingKeyGenerator.new(key_generator) secret = key_generator.generate_key(request.env["action_dispatch.encrypted_cookie_salt"]) sign_secret = key_generator.generate_key(request.env["action_dispatch.encrypted_signed_cookie_salt"]) ActiveSupport::MessageEncryptor.new(secret, sign_secret).decrypt_and_verify(content) rescue ActiveSupport::MessageVerifier::InvalidSignature ‘’ end
13. Custom Middleware class CurrentUserLogger < Rails::Rack::Logger protected def started_request_message(request) 'Started %s "%s" for %s at %s %s' % [ request.request_method, request.filtered_path, request.ip, Time.now.to_default_s, by_current_user(request) ] end private def by_current_user(request) ... end def read_signed_cookie(request) ... end end
