Ruby on rails 在Redmine插件中运行nodeJS代码

如何在Redmine插件中运行nodeJS代码？ 使用nodeJS服务器，或从控制器或其他任何东西

我的插件是一个钩子中的HTML按钮，调用onClick javascript函数。 当我按下这个按钮时，我想运行nodeJs代码。我该怎么办

我使用Redmine 1.4.4

编辑：也许这对我有帮助

我在这里找到了一个解决方案：

From what I know, 3 scenarios:

    You want to use a publicly exposed NodeJS service. 
    In that case just make an ajax call to your service (jQuery).

    You want to use a non-public NodeJS service Run your NodeJS 
    service on localhost (listening to 127.0.0.1) and call it from the controller 
    of your plugin.

    You want to use a task (executable). 
    Run a system("/my/path/executable #{param}") command from the controller 
    of your plugin.

I don't like solution number 3 because there is more possibilities of something 
going wrong.
