如何在ruby Shoes GUI应用程序中创建简单的http请求？

我正在尝试向运行在localhost：3000的本地rails应用程序发出一个简单的http请求。我的应用程序的代码非常处于原型阶段，因为我只是在尝试其他任何事情之前尝试获取原始功能。

I'm trying to make a simple http request to a local rails application running at localhost:3000. The code for my application is very much in prototype phase as I am only trying to get raw functionality before I try anything else.

rails应用程序只返回看起来像的JSON在解析之前

The rails app simply returns JSON that looks like this before being parsed

"{\"response\":\"foo is blank\"}"

这是我现在正在尝试的代码：

Here's the code I'm trying right now:

require 'net/http'

def get_response
  return Net::HTTP.get(URI.parse("http://localhost:3000"))
end

Shoes.app(:width => 280, :height => 350) do

  flow do
    stack do
      button "make http request and display results in an alert box" do
        x = get_response
        alert x
      end# of button
    end# of stack
  end# of flow
end

我也尝试过这个方法在Shoes.app内部阻止无济于事。执行时，这将创建它应该创建的所有元素，但是当我单击按钮时没有任何反应。

I've also tried to put the method inside the Shoes.app block to no avail. When executed, this creates all the elements that it should create, but nothing happens when I click the button.

我知道你不应该做任何事情实用的红宝石鞋，但我还是试着。感谢您的时间

I know you're not supposed to be able to do anything practical with ruby shoes, but I'm trying anyway. Thanks for your time
