Question

有没有办法知道ruby Web服务器（webrick，evma_httpserver等）何时响应了请求？

目标是在将第二个文件提供给客户端之后，提供2个静态文件和关闭服务器。看来我找不到与此相关的任何内容，因此欢迎使用任何指针。

Answer 1

仅关闭服务器，然后提供第二个文件。这是一个示例：

server.rb

require 'webrick'

server = WEBrick::HTTPServer.new :Port => 8000, :DocumentRoot => '/'
server.mount_proc '/' do |req, res|
  # response with simple html body
  res.body = '
  <html>
    <head>
      <title>My Webpage</title>
      <!-- first file -->
      <link rel="stylesheet" href="/one_file.css" type="text/css">
      <!-- second file -->
      <link rel="stylesheet" href="/second_file.css" type="text/css">
    </head>
    <body>
      <h1>Hello world!</h1>
    </body>
  </html>'
end
server.mount_proc '/one_file.css' do |req, res|
  res.body = 'h1 { color: blue; }'
end
server.mount_proc '/second_file.css' do |req, res|
  res.body = 'h1 { color: red; }'
  puts "Shutdown server !"
  server.shutdown
end
server.start

运行server.rb：

$~  ruby server.rb
