Hi,大家好,我是编程小6,很荣幸遇见你,我把这些年在开发过程中遇到的问题或想法写出来,今天说一说python 多进程通信模块「终于解决」,希望能够帮助你!!!。
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
#!/usr/bin/python
# -*- coding: utf-8 -*-
""" download - slave
"""
__author__ = 'Zagfai'
__license__ = 'MIT@2014-02'
import webtul
from multiprocessing.connection import Client
a = 0
try:
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
#!/usr/bin/python
# -*- coding: utf-8 -*-
""" downloader - master server
"""
__author__ = 'Zagfai'
__license__ = 'MIT@2014-02'
import webtul
from multiprocessing.connection import Listener
from 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 = True
listener_th.start()
listener_th.join(timeout=20)
