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

Hello python

Welcom to the python world

测试

测试结果：

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

connect by  ('172.20.52.110', 6096)

GET / HTTP/1.1

Host: 172.20.52.163:20014
