pyzmq的4种模式(pair)笔记

? ? 今天学习下pyzmq,感觉怎么样呢，看了官网开头，记录之,基本上也可以算个翻译

? ? ?Exclusive pair pattern 特点：

? ? ? ? ? ?1. 双向通讯

? ? ? ? ? ?2. 套接字无状态(封装的很好吧)

? ? ? ? ? ?3. 只能有一个对等连接(这能干嘛用，似乎没啥用)

? ? ? ? ? ?4. 服务端监听，客户端连接

然后：你根本不用考虑message接收的完整不完整,你照做就是了！（原文）

官方example在此：

pairserver.py

 1

import zmq
import random
import sys
import time

port = "5556"
context = zmq.Context()
socket = context.socket(zmq.PAIR)
socket.bind("tcp://*:%s" % port)
while True:
    socket.send("Server message to client3")
    msg = socket.recv()
    print msg
    time.sleep(1)

pairclient.py

import zmq
import random
import sys
import time

port = "5556"
context = zmq.Context()
socket = context.socket(zmq.PAIR)
socket.connect("tcp://localhost:%s" % port)
while True:
    msg = socket.recv()
    print msg
    socket.send("client message to server1")
    socket.send("client message to server2")
    time.sleep(1)

?改一下server：

import zmq
import time

port = ‘5556‘
context = zmq.Context()
socket = context.socket(zmq.PAIR)
socket.bind(‘tcp://*:%s‘%port)
i = 0
while True:
	i += 1
	print ‘begin:‘,i
	socket.send(‘msg from server:‘+str(i))
	msg = socket.recv()
	print ‘msg:%s‘%msg
	time.sleep(1)

?run起来：

client:?

begin
msg from server:1
begin
msg from server:2
begin
msg from server:3

?server:

begin: 1
msg:client msg to server -1
begin: 2
msg:client msg to server -2
begin: 3
msg:client msg to server -1
begin: 4
msg:client msg to server -2
begin: 5
msg:client msg to server -1
begin: 6

?好吧，它确实没丢任何message,只能说呵呵，这封装的，有点别扭。
