nginx 的 ruby 中的自定义目录列表处理程序
我刚刚发现 this Question on serverfault，详细介绍了如何使用 php 脚本为 nginx 创建自定义目录列表处理程序。我想做同样的事情，但是使用 ruby 脚本。
location /test/ {
error_page 404 = /webdir/handler.php;
return 404;
}
我的问题是，我是否会简单地做同样的事情，但引用handler.rb而不是handler.php，我的意思是，nginx会自动知道评估ruby脚本的和输出到用户的浏览器？那么我是否只是创建一个执行一些 puts 调用的脚本，或者执行此操作的首选方法是什么？我对rack或sinatra不太了解，但是在这种情况下两者都会派上用场吗？我确实安装了乘客。
我很可能希望在其中包含 css 以使列表看起来不错，并且我可能更喜欢在 haml 或 erb 中创建结构。我不介意结构模板和 CSS 是否需要内联在同一个 handler.rb 中，不过如果可以将其分离到文件中那就太好了。
最后，我希望这适用于 mysite.com/downloads/ 目录及其所有子目录。首选的 location 指令是什么？我看到这
location ~ /$
是为了使其适用于所有目录，但我只希望它适用于 downloads/ 及其任何子目录。我认为这只是一个简单的正则表达式修改，但我宁愿确定。
谢谢，我很感激。
I just found this question on serverfault which details how to create a custom directory listing handler for nginx with a php script. I would like to do the same thing but with a ruby script.
location /test/ {
error_page 404 = /webdir/handler.php;
return 404;
}
My question is, would I simply do the same thing but reference the handler.rb instead of handler.php, I mean, will nginx automatically know to evaluate the ruby script's and output to the user's browser? So do I simply create a script that does some puts calls, or what is the preferred way of doing this? I don't know much about rack or sinatra, but is this a situation in which either would come in handy? I do have passenger installed.
I would most likely want to include css in this to make the listing look nice, and I would possibly prefer to create the structure in haml or erb. I don't mind if the structure template and css would need to be inline in the same handler.rb, though if it's possible to separate it out into files that would be beautiful.
Finally, I would like this to apply to the mysite.com/downloads/ directory as well as all of its sub-directories. What would be the preferred location directive? I saw that
location ~ /$
is to make it work on all directories, but I only want it to apply to downloads/ and any of its subdirectories. I think it'd be a simple regex modification but I'd rather be sure.
Thanks, I appreciate it.

不，nginx 不会自动评估 Ruby 脚本。最好的选择是将处理程序设置为某种 Rack 应用程序（现在几乎所有 Ruby Web 框架或处理程序都是 Rack 应用程序，包括 Sinatra 和 Rails），然后使用乘客或 Ruby 服务器（如 unicorn）设置为nginx 代理。
考虑到您的额外要求，我将首先查看 Sinatra。
No, nginx will not automatically evaluate Ruby scripts. Your best bet is to set up a handler as a Rack application of some sort (pretty much all Ruby web frameworks or handlers are Rack applications these days, including Sinatra and Rails) and then use passenger or a Ruby server like unicorn set up as an nginx proxy.
Given your additional requirements, I would start by looking at Sinatra.
