'分布式进程，客户端'

import time, sys, Queue

from multiprocessing.managers import BaseManager

# 创建类似的QueueManager:

class QueueManager(BaseManager):

pass

# 由于这个QueueManager只从网络上获取Queue，所以注册时只提供名字:

QueueManager.register('get_task_queue')

QueueManager.register('get_result_queue')

# 连接到服务器，也就是运行taskmanager.py的机器:

server_addr = '127.0.0.1'

print('Connect to server %s...' % server_addr)

# 端口和验证码注意保持与taskmanager.py设置的完全一致:

m = QueueManager(address=(server_addr, 5000), authkey='abc')

# 从网络连接:

m.connect()

# 获取Queue的对象:

task = m.get_task_queue()

result = m.get_result_queue()

# 从task队列取任务,并把结果写入result队列:

for i in range(10):

try:

n = task.get(timeout=1)

print('run task %d * %d...' % (n, n))

r = '%d * %d = %d' % (n, n, n*n)

time.sleep(1)

result.put(r)

except Queue.Empty:

print('task queue is empty.')

# 处理结束:

print('worker exit.')
