Redis订阅发布消息实例

Redis订阅和发布消息

首先，发布端启动 redis-server.exe 服务
发布端 pub.py

#!/usr/bin/env python

import redis
import sys
class  PublishChannel(object):
    #kword = u"桌面".encode('gb2312')
    def send_pybot(self,msg):
        message=["msg1","msg2","msg3"]
        '''
        msg1:对参与者端共享app进行外窗口操作
        msg2:对参与者端共享app进行内窗口操作
        msg3:参与者端托盘断开连接重连操作

        '''
        pool=redis.ConnectionPool(host='192.168.3.58',port=6379,db=0)
        r = redis.StrictRedis(connection_pool=pool)
        # input = raw_input("publish:")
        if msg in message:
            r.publish('spub', msg)
        if  input == 'over':
            print '停止发布'
            # break; 
if __name__ == "__main__":
    Do = PublishChannel()
    Do.send_pybot(sys.argv[1])
    print "finish msg to Channel !"

订阅端 sub.py

#!/usr/bin/env python

import redis

import os

p = r.pubsub()

for item in p.listen():    
    print item

            print u"msg1执行完成"
        elif data == message[1]:
            print u"对参与者端的共享app进行内窗口操作"
            #os.system("C:\\JHAppTestAutomation\\JHCoDesign-5.0\\bat\\GotoTestCase2.bat %s " % (x))
        elif data == message[2]:
            print u"对参与者端的共享app进行内窗口操作"
            #os.system("C:\\JHAppTestAutomation\\JHCoDesign-5.0\\bat\\GotoTestCase2.bat %s " % (x))
        elif data == message[3]:
            print u"注销用户!"
            #os.system("C:\\JHAppTestAutomation\\JHCoDesign-5.0\\bat\\GotoTestCase2.bat %s " % (x))
        if  item['data']=='over':
            break; 
p.unsubscribe('spub')
print '取消订阅'

可通过redis-cli.exe进行测试；
cmd 打开redis-cli.exe

---

查看使用方法：
“redis-cli.exe” –help

---

连接至redis服务端：
“redis-cli.exe” -h localhost -p (默认6379)

---

订阅一个频道：
192.168.3.58:6379> subscribe spub
Reading messages… (press Ctrl-C to quit)
1) “subscribe”
2) “spub”
3) (integer) 1

---

发布一个消息：
192.168.3.58:6379> publish spub “hello!”
(integer) 1

---

最后跑通后测试：
订阅端：python sub.py
{‘pattern’: None, ‘type’: ‘subscribe’, ‘channel’: ‘spub’, ‘data’: 1L}

发布端 执行脚本：python pub.py msg1

订阅端：python sub.py
{‘pattern’: None, ‘type’: ‘subscribe’, ‘channel’: ‘spub’, ‘data’: 1L}
对参与者端共享app进行外窗口操作
msg1执行完成
