Nacos初体验
新建命名空间
新建配置
python代码示例
#!/usr/bin/env python3
# -*- coding: utf-8 -*-
import nacos
SERVER_ADDRESSES = "localhost"
# 这里是命名空间的ID，不是命名空间名称
NAMESPACE = "001"
client = nacos.NacosClient(SERVER_ADDRESSES, namespace=NAMESPACE)
# get config
data_id = "aa"
group = "bb"
print(client.get_config(data_id=data_id, group=group))
