Python은 간단한 HttpServer 서버를 구현합니다.

import socket
import sys
import getFileContent
#声明一个将要绑定的IP和端口，这里是用本地地址
server_address = ('localhost', 8080)
class WebServer():
  def run(self):
    print >>sys.stderr, 'starting up on %s port %s' % server_address
    #实例化一个Socket
    sock=socket.socket(socket.AF_INET,socket.SOCK_STREAM)
    #绑定IP和端口
    sock.bind(server_address)
    #设置监听
    sock.listen(1)
    #这里首先给个死循环，其实这里是需要多线程的，再后续版本将会实现
    while True:
      #接受客户端的请求并得到请求信息和请求的端口信息
      connection, client_address = sock.accept()
