python实现简单http服务器功能

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>
