# 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='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()

# 放几个任务进去:

for i in range(10):

n = random.randint(0, 10000)

print('Put task %d...' % n)

task.put(n)

# 从result队列读取结果:

print('Try get results...')

# for i in range(10):

while True:

try:

r = result.get(timeout=2)

print('Result: %s' % r)

except Queue.Empty:

# 2S内取不到结果，返回结果队列为空提示

print('result queue is empty.')

# 关闭:

manager.shutdown()
