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/pythonimport socketimport signalimport errnofrom 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 OKContext-Type: text/htmlServer: Python-slp version 1.0Context-Length: ''' lisfd = socket.socket(socket.AF_INET,socket.SOCK_STREAM)lisfd.bind((HOST, PORT))lisfd.listen(2) signal.signal(signal.SIGINT,sigIntHander) runflag = Truewhile 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>
