python實現(xiàn)簡單http服務(wù)器功能

 更新時間：2018年09月17日 10:07:00   作者：ordeder  
這篇文章主要為大家詳細介紹了python實現(xiàn)簡單http服務(wù)器功能，具有一定的參考價值，感興趣的小伙伴們可以參考一下

背景

寫一個python腳本，實現(xiàn)簡單的http服務(wù)器功能：

1.瀏覽器中輸入網(wǎng)站地址：172.20.52.163:20014

2.server接到瀏覽器的請求后，讀取本地的index.html文件的內(nèi)容，回發(fā)給瀏覽器

代碼實現(xiàn)

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>

測試

測試結(jié)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
Connection: keep-alive
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8
User-Agent: Mozilla/5.0 (Windows NT 5.1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/33.0.1750.154 Safari/537.36
Accept-Encoding: gzip,deflate,sdch
Accept-Language: zh-CN,zh;q=0.8,en;q=0.6

以上就是本文的全部內(nèi)容，希望對大家的學(xué)習(xí)有所幫助，也希望大家多多支持腳本之家。
