这篇文章主要为大家详细介绍了Python实现一个简单http服务器，具有一定的参考价值，感兴趣的小伙伴们可以参考一下

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>

测试

测试结果：

									root@cloud2:~/slp/pythonLearning/socket# ./server_v1.py 

									connect by ('172.20.52.110', 6096)
