The code for App runs fine when run on it's own, so it's not included here, the problem is with the Rack part. I'd like to do something like this: app = Rack::Builder.app do map "/" do Rack::Handler::WEBrick.run App,

问题 I'm trying to write some Rack Middleware for a Rails 4.2 app that alters the response body using the gsub method. I found older examples that use a pattern like this: class MyMiddleware def initialize(app) @app = app end def call(env) status, headers, response = @app.call(env) # do some stuff [status, headers, response] end end What I'm finding is that there is no setter method for response.body . Is there another pattern I can start with to go about modifying the body? 回答1: The problem was

问题 Ok, I'm making my first ruby app. Who know moving everything over to 'production' is so fugging complicated.

问题 I have an pretty simple app hosted on EC2 built with Sinatra, served with thin behind nginx. The problem is that with Chrome, the session variables get 'lost' in Sinatra. It does not happen in Firefox. This is using Rack::Session::Cookie. This is similar to this issue: Sinatra not persisting session with redirect on Chrome Any insights in how to solve this issues in Chrome would be appreciated. 回答1: Make sure you are setting the following: configure :development do set(:session_secret, 'a

问题 a classic hello world example from their doc, class HelloWorld def call(env) return [200, {}, ["Hello world!"]] end end my question is why the third value is [Hello world!"], not "Hello world"?
