Question

在我的zmq项目中，我正在尝试为各种类型动态创建套接字。但是，当我运行此脚本时，获取＆＃34;地址已使用错误＆＃34;。

helpers.py

def create_connection(sock_type, address, port, \
                      connection_method, \
                      topic_filter=""):
"""
This fn helps to create a websocket according to the args
:sock_type = PUB, PUSH, PULL, SUB
:address = "127.0.0.1"
:port = 5376
:connection_method = bind or connect
:topic_filter = if the sock_type PULL, pass the topic filter

"""
context = zmq.Context()
ws = context.socket(SOCK_TYPES[sock_type])

if connection_method == 'bind':
    ws.bind("tcp://%s:%s" %(address, port))
else:
    ws.connect("tcp://%s:%s" %(address, port))

if sock_type == 'SUB':
    ws.setsockopt(zmq.SUBSCRIBE, topic_filter)

print "ws for ",sock_type, address, port, \
                      connection_method, \
                      topic_filter
return ws

module.py

from helpers import create_connection
def worker(pid):

        work_receiver = create_connection("PULL", WORKER_IP, WORKER_PORT, "connect")
        result_sender = create_connection("PUSH", RESULT_SENDER_IP, RESULT_SENDER_PORT, "bind")
        result_status_receiver = create_connection("SUB", RESULT_COLLECTOR_IP, RESULT_COLLECTOR_PORT, "connect")

     ......
     ......

for worker_id in range(10):
    Process(target=worker, args=(worker_id,)).start()

如果我们通过在工作模块中进行硬编码来创建它，而不是动态套接字创建，它似乎有效

settings.py

CONTROLLER_IP = "127.0.0.1"
CONTROLLER_PORT = 5676

WORKER_IP = "127.0.0.1"
WORKER_PORT = 5677

RESULT_SENDER_IP = "127.0.0.1"
RESULT_SENDER_PORT = 5672

RESULT_COLLECTOR_IP = "127.0.0.1"
RESULT_COLLECTOR_PORT = 5678

错误

修改

顺序运行时没有错误

for i in range(10):
        worker(i)

ZMQError：地址已在使用中（使用多处理创建动态套接字）
