python多进程通信模块的简单实现

多进程通信方法好多,不一而数。刚才试python封装好嘅多进程通信模块 multiprocessing.connection。

简单测试咗一下,效率还可以,应该系对socket封装,效率可以达到4krps,可以满足好多方面嘅需求啦。

附代码如下:

client

代码如下:

#!/usr/bin/python# -*- coding: utf-8 -*-“”” download – slave”””__author__ = ‘zagfai’__license__ = ‘mit@2014-02’

import webtulfrom multiprocessing.connection import client

a = 0try: while true: a += 1 address = (‘10.33.41.112′, 6666) conn = client(address, authkey=’hellokey’) #print conn.recv() d = conn.recv() conn.close()except: pass

print a

server

代码如下:

#!/usr/bin/python# -*- coding: utf-8 -*-“”” downloader – master server”””__author__ = ‘zagfai’__license__ = ‘mit@2014-02’

import webtulfrom multiprocessing.connection import listenerfrom threading import thread

def listener(): address = (‘10.33.41.112′, 6666) listener = listener(address, backlog=100, authkey=’hellokey’) while true: conn = listener.accept() #print ‘connection accepted from’, listener.last_accepted try: conn.send({‘1’:2, ‘2’:’abc’}) except exception, e: print e finally: conn.close() listener.close()

listener_th = thread(target=listener)listener_th.daemon = truelistener_th.start()listener_th.join(timeout=20)
