Rack :: Sessione: errore nei cookie utilizzando Sinatra, Thin, Rails e Rack :: Cascade

Question

Ho un'app combinata Sinatra/Rails che condivide una sessione utilizzando Rack :: Session :: Cookie. L'applicazione funziona bene quando viene avviato con Rack :: :: Handler Thin.run app, ma se il file viene rackup iniziare con sottile inizio, ottengo un errore nel rack :: sessione :: Cookie:

Il file rackup simile a questo:

require ::File::dirname(__FILE__) + '/config/environment' 
require 'thin' 

app = Rack::Builder.new { 
    use Rails::Rack::Static 
    run Rack::Cascade.new([Sinatra::Application, ActionController::Dispatcher.new]) 
}.to_app 

use Rack::Session::Cookie, :key => '_example', :domain => 'example.org', 
    :secret => 'secret' 

# have to use this 
Rack::Handler::Thin.run app, :Port => 4000, :Host => "0.0.0.0" 
# want to use: run app 

Answer 1

hai provato qualcosa di simile:

app = Rack::Builder.new { 
    use Rack::Session::Cookie, :key => '_example', :domain => 'example.org', :secret => 'secret' 
    use Rails::Rack::Static 
    run Rack::Cascade.new([Sinatra::Application, ActionController::Dispatcher.new]) 
}.to_app 

sembra yo Il tuo problema è che stai usando Rack :: Session :: Cookie al di fuori di app.
