为什么zeromq在本地主机上不起作用? [英] Why doesn't zeromq work on localhost?

问题描述

此代码非常有用:

import zmq, json, time

def main():
    context = zmq.Context()
    subscriber = context.socket(zmq.SUB)
    subscriber.bind("ipc://test")
    subscriber.setsockopt(zmq.SUBSCRIBE, '')
    while True:
        print subscriber.recv()

def main():
    context = zmq.Context()
    publisher = context.socket(zmq.PUB)
    publisher.connect("ipc://test")
    while True:
        publisher.send( "hello world" )
        time.sleep( 1 )

但是此代码不起作用 *有效:

import zmq, json, time

def recv():
    context = zmq.Context()
    subscriber = context.socket(zmq.SUB)
    subscriber.bind("tcp://localhost:5555")
    subscriber.setsockopt(zmq.SUBSCRIBE, '')
    while True:
        print subscriber.recv()

def send():
    context = zmq.Context()
    publisher = context.socket(zmq.PUB)
    publisher.connect("tcp://localhost:5555")
    while True:
        publisher.send( "hello world" )
        time.sleep( 1 )

它会引发此错误:

ZMQError:没有这样的设备

ZMQError: No such device

为什么zeromq无法使用localhost接口?

Why, can't zeromq use localhost interfaces?

仅在同一台计算机上的IPC上工作吗?

Does it only work on IPC on the same machine?

推荐答案

问题出在行:

subscriber.bind("tcp://localhost:5555")

尝试更改为:

subscriber.bind("tcp://127.0.0.1:5555")
