PAIR / PAIR通信原型中的PyZMQ用户输入（）

Question

我正在使用PyZMQ创建一个简单的PAIR / PAIR通信原型消息传递模式。

PairServer

import zmq
import random
import sys
import time

port = "9999"
context = zmq.Context()
socket = context.socket(zmq.PAIR)
print("Binding socket to port: " + str(port))
socket.bind("tcp://*:%s" % port)
print("Connection has been established")

while True:
    data = input("Enter: ")
    socket.send_string(data)
    msg = str(socket.recv(), "utf-8")
    print("Received: ",msg)
    time.sleep(2)

PairClient

import zmq
import random
import sys
import time

port = "9999"
context = zmq.Context()
socket = context.socket(zmq.PAIR)
print("Connecting socket to port: " + str(port))
socket.connect("tcp://localhost:%s" % port)
print("Connected")

count = 0
response = 1

while True:
    msg = str(socket.recv(), "utf-8")
    print("Received: ",msg)
    count = count + 1
    print("Counter: ",count)

    if count == response:
        data = "Client has received message from server: " + msg
        socket.send_string(data)
        response = response + 1
        time.sleep(2)

我无法将用户输入从服务器发送到客户端，因为当我按Enter键时无法发送，但能够从服务器向客户端发送和接收硬编码消息。当我这样做时，有时会在客户端收到从服务器端收到的消息。我不确定这是否是由于两个脚本都在localhost上运行而且套接字内部存在冲突。

例如，

PairServer

data = "random data"

PairClient

输出：

Received:  random data
Counter:  4
Received:  Client has received message from server: random data
Received:  random data
Counter:  5
Received:  random data
Counter:  6

如何发送用户输入并防止客户端在localhost上接收从客户端到服务器收到的消息（如果这是问题）？

我修复了 input() 问题。我意识到Sublime3无法运行输入命令。我通过安装SublimeREPL包修复了这个问题。

虽然我仍然没有具体的想法，为什么客户端会在localhost上收到有时从客户端收到消息的消息。
