This article mainly introduces Python to implement a simple http server in detail, which has certain reference value. Interested friends can refer to

Write a python script to implement a simple http server. Function:

1. Enter the website address in the browser: 172.20.52.163:20014

2. After the server receives the request from the browser, it reads the contents of the local index.html file. Post back to the browser

Code implementation

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 = &#39;&#39;.join(contxtlist) 
  response = "%s %d\n\n%s\n\n" % (header,len(context),context) 
  return response 
 
def sigIntHander(signo,frame): 
  print &#39;get signo# &#39;,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 = &#39;&#39;&#39;&#39;&#39;\ 
HTTP/1.1 200 OK 
Context-Type: text/html 
Server: Python-slp version 1.0 
Context-Length: &#39;&#39;&#39; 
 
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 &#39;get a except EINTR&#39; 
    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,&#39;index.html&#39;)) 
  confd.close() 
else: 
  print &#39;runflag#&#39;,runflag 
 
print &#39;Done&#39;
