Question

我的服务器在Tomcat上运行JRuby on Rails，其GWT前端通过gwt :: RequestBuilder连接。当我在Tomcat上运行WEBrick以及开发模式时，一切似乎都运行良好，但在生产模式下，一件奇怪的事情正在发生。我的登录控制器有一个在您第一次点击页面时运行的操作：

def is_logged_in
  if session[:current_user]
    # do some stuff and render response XML
  else
    puts "nothing status unauthorized"
    render :nothing => true, :status => :unauthorized
  end
end

在开发中，它工作正常，我收到401 Unauthorized错误，GWT选择它并显示登录屏幕。在生产中，我得到200 OK，没有XML响应体，即使服务器日志中出现“未授权状态”。清除Tomcat临时文件夹和webapp文件夹没有帮助。是什么赋予了？感谢您的帮助，希望这是我忽略的一些简单。

供参考：我在Windows 7 x64中使用JRuby 1.6.6和Tomcat7。

的Gemfile

gem 'rails', '3.0.3'

gem 'haml'

# Bundle edge Rails instead:
# gem 'rails', :git => 'git://github.com/rails/rails.git'

platforms :ruby do
  gem 'mysql2'

# Bundle the extra gems:

为了进一步阐述希望某种灵魂指向我正确的方向，我98％确定问题在于Rails代码而不是GWT，因为对is_logged_in路由执行CURL会导致200 OK好。

更新2

这是我发现的另一个小故事，至少让我回到了工作状态，但仍然留下了许多未解决的问题。我最近更新了jruby-1.6.6，但保留了我的版本jruby-1.6.0以防万一。当我使用旧的jruby吵醒时，事情又开始起作用了。但这只是指向jruby版本和一堆宝石，我不知道如何开始找到罪魁祸首。是否有人熟悉一连串的插件，指出我正确的方向？

搁置并重新审视之后。我几乎可以肯定它与轨道宝石的版本很麻烦。我用两个版本的JRuby生成了WAR，1.6.0和1.6.6。代码是相同的，但1.6.0没有问题，而1.6.6有上面提到的问题，结果是所有控制器总是只在生产中输出200 OK响应，无论我明确设置什么状态代码。希望有人找到了解决这个问题的方法，并且已经在更新的JRuby gem版本中进行了修改。

Answer 1

使用logger.warn代替puts。另外，仅使用head返回标题。

logger.warn "nothing status unauthorized"
head :unauthorized

JRuby on Rails生产响应200 OK即使控制器代码设置状态：未授权
