查看etcd中间件版本
etcd --version
etcd Version: 3.4.7
Git SHA: e694b7bb0
Go Version: go1.12.17
Go OS/Arch: windows/amd64

3.0以上的版本,需要etcd3模块支持连接(测试python-etcd,etcd不行)

##coding
import etcd3
client = etcd3.client(host='127.0.0.1', port=2379)
client.put("name","egon") //设置
client.get("name") //获取
vents_iterator, cancel = client.watch('aaa')         #监听etcd中aaa键 是否发生改变，
print(event).value
