How can I skip rails warden authentication for sidekiq engine route?

Question

I am using sidekiq 4.1.4 with Rails 4.2.6.

The route file has below code:

require 'sidekiq/web'
mount Sidekiq::Web, at: '/sidekiq'

When I access sidekiq UI through http://localhost:3000/sidekiq , it shows error:

{
    "errors": [
        "Unauthorized Request"
    ]
}

I'm using warden authentication and the initializer file has this code:

Rails.application.config.middleware.insert_after ActionDispatch::ParamsParser, Warden::Manager do |manager|
  manager.default_strategies :authentication_token
  manager.failure_app = UnauthenticatedController
end

Answer 1

I was able to access sidekiq at http://my_domain.com/sidekiq with these changes:

Create an initializer with below code:

class MountedAppAuth
  def initialize( app )
    @app = app
  end

  def call( env )
    @app.call( env )
  end
end

In routes.rb:

require 'sidekiq/web'
Sidekiq::Web.use MountedAppAuth
mount Sidekiq::Web, at: '/sidekiq'
