Using Redis pub/sub time subscription and publishing messages

ImportRedisImportTimer=redis. Strictredis (host="127.0.0.1", port=6379)#you can also choose to use the address pool to establish a connection whileTrue:if __name__='__main__': Dis=get_distance () p=r.publish () p.subscribe ("First channel")#SubscribeR.publish ("First channel", dis)#published (called the Get_distance function)p.get_message () time.sleep (0.5)#when the network status is poor, the return value is none if the suspend time is too shortA=p.get_message ()PrintA

Here I put the public with subscribe in the same function to run.

Test results:

In addition, this is just a message that can be read out after the subscription is received. To process a message, you need to use a callback function.

Operating Environment:

python-2.7

Ubuntu 16.4
