ruby-on-rails - 使用Sinatra，Thin，Rails和Rack::Cascade的Rack::Session:Cookie错误

Question

我有一个组合的Sinatra/Rails应用程序，该应用程序使用Rack::Session::Cookie共享一个 session 。使用Rack::Handler::Thin.run应用程序启动时，该应用程序运行良好，但是如果 Rack 文件以瘦启动方式启动，则在Rack::Session::Cookie中出现错误:

Rack 文件如下所示:

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

您是否尝试过像这样的事情:

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

看来您的问题是您在app之外使用Rack::Session::Cookie。
