Redis訂閱發佈消息實例

Redis訂閱和發佈消息

首先，發佈端啓動 redis-server.exe 服務
發佈端 pub.py

#!/usr/bin/env python
# -*- coding: utf-8 -*-

import redis
import sys
class  PublishChannel(object):
    #kword = u"桌面".encode('gb2312')
    def send_pybot(self,msg):
        message=["msg1","msg2","msg3"]
        '''
        msg1:對參與者端共享app進行外窗口操作
        msg2:對參與者端共享app進行內窗口操作
        msg3:參與者端托盤斷開連接重連操作

        '''
        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 '停止發佈'
            # break; 
if __name__ == "__main__":
    Do = PublishChannel()
    Do.send_pybot(sys.argv[1])
    print "finish msg to Channel !"

訂閱端 sub.py

#!/usr/bin/env python

import redis

import os
pool=redis.ConnectionPool(host='192.168.3.58',port=6379,db=0)
#db=0，選擇操作0號數據庫  redis默認有16個數據庫  conf可以配置

for item in p.listen():    
    print item

        data = item['data']
        # print data
        if data == message[0]:

            os.system("C:\JHAppTestAutomation\JHCoDesign-5.0\JHApp-4.0.0\bat\GotoTestCase1.bat")
            print u"msg1執行完成"
        elif data == message[1]:
            print u"對參與者端的共享app進行內窗口操作"
            #os.system("C:\\JHAppTestAutomation\\JHCoDesign-5.0\\bat\\GotoTestCase2.bat %s " % (x))
        elif data == message[2]:
            print u"對參與者端的共享app進行內窗口操作"
            #os.system("C:\\JHAppTestAutomation\\JHCoDesign-5.0\\bat\\GotoTestCase2.bat %s " % (x))
        elif data == message[3]:
            print u"註銷用戶!"
            #os.system("C:\\JHAppTestAutomation\\JHCoDesign-5.0\\bat\\GotoTestCase2.bat %s " % (x))
        if  item['data']=='over':
            break; 
p.unsubscribe('spub')
print '取消訂閱'

可通過redis-cli.exe進行測試；
cmd 打開redis-cli.exe

---

查看使用方法：
“redis-cli.exe” –help

---

連接至redis服務端：
“redis-cli.exe” -h localhost -p (默認6379)

---

訂閱一個頻道：
192.168.3.58:6379> subscribe spub
Reading messages… (press Ctrl-C to quit)
1) “subscribe”
2) “spub”
3) (integer) 1

---

發佈一個消息：
192.168.3.58:6379> publish spub “hello!”
(integer) 1

---

最後跑通後測試：
訂閱端：python sub.py
{‘pattern’: None, ‘type’: ‘subscribe’, ‘channel’: ‘spub’, ‘data’: 1L}

發佈端 執行腳本：python pub.py msg1

訂閱端：python sub.py
{‘pattern’: None, ‘type’: ‘subscribe’, ‘channel’: ‘spub’, ‘data’: 1L}
對參與者端共享app進行外窗口操作
msg1執行完成
