这篇文章主要为大家详细介绍了python实现简单http服务器功能，具有一定的参考价值，感兴趣的小伙伴们可以参考一下

背景

写一个python脚本，实现简单的http 服务器功能：

1.浏览器中输入网站地址：172.20.52.163:20014

2.server接到浏览器的请求后，读取本地的index.html文件的内容，回发给浏览器

代码实现

server.py

									#!/usr/bin/python

									import socket

									import signal

									import errno

									from time import sleep 

									def HttpResponse(header,whtml):

									 f = file(whtml)

									 contxtlist = f.readlines()

									 context = ''.join(contxtlist)

									 response = "%s %d\n\n%s\n\n" % (header,len(context),context)

									 return response

									def sigIntHander(signo,frame):

									 print 'get signo# ',signo

									 global runflag

									 runflag = False

									 global lisfd

									 lisfd.shutdown(socket.SHUT_RD)

									strHost = "172.20.52.163"

									HOST = strHost #socket.inet_pton(socket.AF_INET,strHost)

									PORT = 20014

									httpheader = '''\

									HTTP/1.1 200 OK

									Context-Type: text/html

									Server: Python-slp version 1.0

									Context-Length: '''

									lisfd = socket.socket(socket.AF_INET,socket.SOCK_STREAM)

									lisfd.bind((HOST, PORT))

									lisfd.listen(2)

									signal.signal(signal.SIGINT,sigIntHander)

									runflag = True

									while runflag:

									 try:

									  confd,addr = lisfd.accept()

									 except socket.error as e:

									  if e.errno == errno.EINTR:

									   print 'get a except EINTR'

									  else:

									   raise

									  continue

									 if runflag == False:

									  break;

									 print "connect by ",addr

									 data = confd.recv(1024)

									 if not data:

									  break

									 print data

									 confd.send(HttpResponse(httpheader,'index.html'))

									 confd.close()

									else:

									 print 'runflag#',runflag

									print 'Done'

index.html

									<html>

									 <head>

									 <title>Python Server</title>

									 </head>

									 <body>

									 <h1>Hello python</h1>

									 <p>Welcom to the python world</br>

									 </body>

									</html>
