用 Rack::Directory

@fsword 谢谢 参数的解释 Obviously, ruby is the normal Ruby interpreter. The -r switch requires a file in the load path, in this case Ruby’s lib directory. In this case, it’s loading a file called un.rb so that it looks like -run when taken as a whole. (It could be written as -r un as well.) This is similar to ubygems.rb which you may have seen as ruby -rubygems. That seems like an ugly solution, but it’s elegant in its own way. This naming hack is only really an option for files in Ruby itself, anyway. As you can see above, httpd is just a method, which is executed by -e. The DocumentRoot argument . is just taken as a standard argument using ARGV, which I found surprising. Finally, the port is set using the setup method, which in turn calls out to the built in OptionParser.

python -m SimpleHTTPServer

gem install Rwebserver

gem "asdf"

仅一个方法

module Asdf
  class Server < ::Rack::Server
    def app
      Rack::Directory.new(Dir.pwd)
    end
  end
end

不止 Ruby，很多语言都有简单启动 server 的方法。Google 一下 one line server。或者看 这个链接
