Question

有人可以向我解释一下这段代码的每一部分是做什么的吗？如果有人能给我一步一步的解释会很有帮助。另外，我怎么能上传文件？我如何操作一般的ruby服务器？

#!/usr/bin/env ruby

require 'socket'
require 'cgi'

server = TCPServer.new('127.0.0.1', 8888)
puts 'Listening on 127.0.0.1:8888'

loop {
  client = server.accept

  first_request_header = client.gets
  resp = first_request_header

  headers = ['http/1.1 200 ok',
             "date: #{CGI.rfc1123_date(Time.now)}",
             'server: ruby',
             'content-type: text/html; charset=iso-8859-1',
            "content-length: #{resp.length}\r\n\r\n"].join("\r\n")
  client.puts headers          # send the time to the client
  client.puts resp
  client.close
}

#required gems
require 'socket'
require 'cgi'

#creating new connection to a local host on port 8888
server = TCPServer.new('127.0.0.1', 8888)
puts 'Listening on 127.0.0.1:8888'

loop {
  #looks like a client method call to open the connection
  client = server.accept
  first_request_header = client.gets
  resp = first_request_header

  #setting the request headers
  headers = ['http/1.1 200 ok',
             "date: #{CGI.rfc1123_date(Time.now)}",
             'server: ruby',
             'content-type: text/html; charset=iso-8859-1',
            "content-length: #{resp.length}\r\n\r\n"].join("\r\n")

  #inserts custom client headers into request
  client.puts headers         
  client.puts resp

  #closes client connection to local host
  client.close
}
