python使用zeroMQ库的套接字模拟服务器客户端通信

首先是等待请求的服务器:

import zmqhost = '127.0.0.1'port = 6789context = zmq.Context()server = context.socket(zmq.REP)server.bind("tcp://%s:%s" % (host, port))while True:    #  Wait for next request from client    request_bytes = server.recv()    request_str = request_bytes.decode('utf-8')    print("That voice in my head says: %s" % request_str)    reply_str = "Stop saying: %s" % request_str    reply_bytes = bytes(reply_str, 'utf-8')    server.send(reply_bytes)
注意
server.bind("tcp://%s:%s" % (host, port))
这里地址和端口用的是字符串,并不是普通套接字里面的元组

下面是对应的发送请求的客户端:

import zmqimport timehost = '127.0.0.1'port = 6789context = zmq.Context()client = context.socket(zmq.REQ)client.connect("tcp://%s:%s" % (host, port))for num in range(1, 6):    request_str = "message #%s" % num    request_bytes = request_str.encode('utf-8')    client.send(request_bytes)    reply_bytes = client.recv()    reply_str = reply_bytes.decode('utf-8')    print("Sent %s, received %s" % (request_str, reply_str))    time.sleep(2)

客户端会发送5次请求后关闭,服务器则会一直监听

在命令行下分别运行即可:python zmq_server.py     python zmq_client.py
