# task_master.py

import random, time, queue
from multiprocessing.managers import BaseManager

# 发送任务的队列:
task_queue = queue.Queue()
# 接收结果的队列:
result_queue = queue.Queue()

# 从BaseManager继承的QueueManager:
class QueueManager(BaseManager):
    pass

# 把两个Queue都注册到网络上, callable参数关联了Queue对象:
QueueManager.register('get_task_queue', callable=lambda: task_queue)
QueueManager.register('get_result_queue', callable=lambda: result_queue)
# 绑定端口5000, 设置验证码'abc':
manager = QueueManager(address=('', 5000), authkey=b'abc')
# 启动Queue:
manager.start()
# 获得通过网络访问的Queue对象:
task = manager.get_task_queue()
result = manager.get_result_queue()

print('Try to put tasks...')
# 放几个任务进去:
for i in range(10):
    n = random.randint(0, 10000)
    print(f'Put Task [{n}]')
    task.put(n)

# 从result队列读取结果:
print('Try to get results...')

        r = result.get(timeout=20)
        print(f'Get Result: [{r}]')

# 关闭:
manager.shutdown()
print('master exit.')

# task_worker.py

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task_master.py的机器:
server_addr = '127.0.0.1'
print(f'Connect to server ({server_addr})...')
# 端口和验证码注意保持与task_master.py设置的完全一致:
m = QueueManager(address=(server_addr, 5000), authkey=b'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(f'Run Task {n} * {n}...')
        r = f'{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.')
