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>
测试
测试结果：
