连接redis 执行命令  cmdPic.py
#!usr/bin/evn python
#coding=utf-8
import redis
import json
import base64
import time
import Fileout
def Excute(strTime):
    #连接
    r=redis.Redis(host='192.168.20.153',port=6379)
    #写
    Fileout.ReadPic(r)
    data={"order":"11","camera":[{"id":"130000000000","position":["11","12"]}]};
    sdata=json.dumps(data)
    str=r.set('orders_001_'+strTime,sdata)
    print(str)
    Fileout.ReadPic('Set key'+'orders_001_'+strTime)
    temp=r.get('orders_001_'+strTime)#decode()解决Python3输出带b
    Fileout.ReadPic('Get keyValue'+'orders_001_'+strTime)
