本文实例讲解了python实现两个程序之间通信的方法，具体方法如下：

该实例采用socket实现，与socket网络编程不一样的是socket.socket(socket.AF_UNIX, socket.SOCK_STREAM)的第一个参数是socket.AF_UNIX
而不是 socket.AF_INET
例中两个python程序 s.py/c.py 要先运行s.py
基于fedora13/python2.6测试，成功实现！

s.py代码如下：

#!/usr/bin/env python
import socket
import os

if __name__ == '__main__':
  sock = socket.socket(socket.AF_UNIX, socket.SOCK_STREAM)
  conn = '/tmp/conn'
  if not os.path.exists(conn):
  os.mknod(conn)
  if os.path.exists(conn):
  os.unlink(conn)
  sock.bind(conn)
  sock.listen(5)
  while True:
  connection,address = sock.accept()
  data = connection.recv(1024)
  if data == "hello,server":
    print "the client said:%s!\n" % data
      connection.send("hello,client")
  connection.close()
Copy after login

c.py代码如下：

#!/usr/bin/env python
import socket
import time

if __name__ == '__main__':
  sock = socket.socket(socket.AF_UNIX, socket.SOCK_STREAM)
  conn = '/tmp/conn'
  sock.connect(conn)
  time.sleep(1)
  sock.send('hello,server')
  print sock.recv(1024)
  sock.close()
Copy after login
