Python BaseHTTPServer，如何将多个主机重定向到 ip/port？

Question

我目前有以下代码：

from BaseHTTPServer import BaseHTTPRequestHandler
from pathlib import Path
from random import randint

import json
import random

example = 'logs/example.json'

class GetHandler(BaseHTTPRequestHandler):

    # Slurp data from file
    def dummy_data(self):
        json_result = Path(example)

        if json_result.is_file():
            return json.load(open(example))

    # Return data or empty
    def random_selection(self):
        data = self.dummy_data()

        try:
            return random.sample(data, randint(1, len(data)+50))
        # Purposefully introduce entropy
        except ValueError:
            return ''

    def do_GET(self):
        self.send_response(200)
        self.send_header('Content-Type', 'application/json')
        self.end_headers()

        self.wfile.write(json.dumps(self.random_selection()))
        return

if __name__ == '__main__':
    from BaseHTTPServer import HTTPServer
    server = HTTPServer(('localhost', 8080), GetHandler)
    print 'Starting server at http://127.0.0.1:8080'


server.serve_forever()

我已经对 /etc/hosts 进行了如下修补：

server-0001 server-0002 server-0003 server-0004 127.0.0.1

我正在寻找让服务器 0001-4 重定向到 127.0.0.1:8080 的方法，但我不知道如何做？这与/etc/resolv.conf有关吗？我正在使用 OSX 但希望任何 *nix 解决方案都应该工作我希望（除非 ipfw 显然，因为我们不再像理智的人那样拥有它）。

看起来最明智的答案是修补 /etc/hosts，然后将 BaseHTTPServer 的端口更改为 80。这并没有解决最初的问题，而是一个公平的妥协。

修补脚本：

#!/bin/bash

# ensure running as root
if [ "$(id -u)" != "0" ] ; then
  exec sudo "[=10=]" "$@"
fi


if ! grep "^#- marker " /etc/hosts ; then
  echo -e '\n##+ marker' >> /etc/hosts
  while read server ; do
    [ 'x' != "${server}x" ] && echo -e "127.0.0.1 ${server}.io www.${server}.io" >> /etc/hosts
  done <read/servers.txt
  echo -e '\n##- marker' >> /etc/hosts
fi

修改为Python

....
def main():
    try:
        server = HTTPServer(('', 80), GetHandler)
        print '->> Starting server at http://127.0.0.1:80 and all patched hosts'
        server.serve_forever()
    except KeyboardInterrupt:
        print '->> Interrupt received; closing server socket'
        server.socket.close()

if __name__ == '__main__':
    main()
