How to setup URLs for static site with Ruby Rack o

问题:

My site is here.

It used to be a Django-powered blog. However I no longer update it so I just wanted to make it a static HTML site. I wget'ed it and moved it to Heroku with Ruby Rack.

However every URL resolves to the home page. This is because of my config.ru file:

use Rack::Static, 
  :urls => ["/media/images", "/media/js", "/media/css"],
  :root => "public"

run lambda { |env|
  [
    200, 
    {
      'Content-Type'  => 'text/html', 
      'Cache-Control' => 'public, max-age=86400' 
    },
    File.open('public/index.html', File::RDONLY)
  ]
}

Question: Is there a way to map multiple URLs? e.g. foo.com/about maps to public/about/index.html, foo.com/posts/2012/oct/21/blog-postmaps to public/posts/2012/oct/21/blog-post/index.html

At this point I'd even be fine typing each one by hand.

Thanks for your help.

For now I found the best answer to be:

use Rack::Static, 
  :urls => ["/media/images", "/media/js", "/media/css"],
  :root => "public"

map "/" do
  run lambda { |env|
  [
    200, 
    {
      'Content-Type'  => 'text/html', 
      'Cache-Control' => 'public, max-age=86400' 
    },
    File.open('public/index.html', File::RDONLY)
  ]
}
end

map "/portfolio" do
  run lambda { |env|
  [
    200, 
    {
      'Content-Type'  => 'text/html', 
      'Cache-Control' => 'public, max-age=86400' 
    },
    File.open('public/portfolio/index.html', File::RDONLY)
  ]
}
end

And map every URL to its respective file. Tedious, but works. See also the answer to this question regarding URL variables. Couldn't get it to work for me though.

Why do you need the run statement? Maybe this works for you:

use Rack::Static, 
  :urls => ["/media/images", "/media/js", "/media/css"],
  :root => "public",
  :index => "index.html",
  :header_rules => [
    [:all, {'Cache-Control' => 'public, max-age=86400'}]
  ]

run lambda{ |env| [ 404, { 'Content-Type'  => 'text/html' }, ['404 - page not found'] ] }
