Python PyZMQ:权限被拒绝

代码：

错误：

import zmq
from multiprocessing import Process
import time

def server():
    port = '5556'
    context = zmq.Context()
    socket = context.socket(zmq.PAIR)
    socket.bind('tcp://*:%s' % port)

    for i in range(10):
        socket.send('server to client')
        msg = socket.recv()
        print msg
        time.sleep(1)

def client():
    port = '5556'
    context = zmq.Context()
    socket = context.socket(zmq.PAIR)
    socket.bind('tcp://127.0.0.1:%s' % port)

    for i in range(10):
        msg = socket.recv()
        print msg
        socket.send('msg to server')
        time.sleep(1)

if __name__ == '__main__':
    Process(target=server, args=()).start()
    Process(target=client, args=()).start() 

它能够为服务器启动进程1吗？为什么不同的许可

试图学习ZMQ，但无法获得任何简单的例子来运行这一原因。是否有地方可以打开ZMQ的权限？找不到有关此问题的文档

您只能在一侧（服务器）绑定。在客户端上，您必须使用

.connect

，尽管我得到的是“地址已在使用”错误，而不是权限被拒绝

尝试更改它，以便客户端连接并查看它是否适合您：

Process Process-2:
Traceback (most recent call last):
File "C:\Python27\lib\multiprocessing\process.py", line 258, in _bootstrap
self.run()
File "C:\Python27\lib\multiprocessing\process.py", line 114, in run
self._target(*self._args, **self._kwargs)
File "C:\...\zmqtest.py", line 21, in client
socket.bind('tcp://127.0.0.1:%s' % port)

服务器绑定可能是唯一的问题。您可以在windows防火墙中打开端口。服务器绑定可能是唯一的问题。您可以在windows防火墙中打开端口。服务器绑定可能是唯一的问题。您可以在windows防火墙中打开端口。服务器绑定可能是唯一的问题。您可以在windows防火墙中打开端口。非常感谢您对我犯下的这个明显错误有耐心。非常感谢您对我犯下的这个明显错误有耐心。非常感谢您对我犯下的这个明显错误有耐心。非常感谢您对我犯下的这个明显错误有耐心。
