python实现进程间通信简单实例

本文实例讲解了python/' target='_blank'>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 pythonimport socketimport osif __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() 

c.py代码如下：

#!/usr/bin/env pythonimport socketimport timeif __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()
