Nacos文档

服务（Service）是 Nacos 世界的一等公民。Nacos 支持几乎所有主流类型的“服务”的发现、配置和管理：

import nacos

# Both HTTP/HTTPS protocols are supported, if not set protocol prefix default is HTTP, and HTTPS with no ssl check(verify=False)
# "192.168.3.4:8848" or "https://192.168.3.4:443" or "http://192.168.3.4:8848,192.168.3.5:8848" or "https://192.168.3.4:443,https://192.168.3.5:443"
SERVER_ADDRESSES = "http://换成自己的ip:端口"
NAMESPACE = ""

# no auth mode
client = nacos.NacosClient(SERVER_ADDRESSES, namespace=NAMESPACE)
# auth mode
# client = nacos.NacosClient(SERVER_ADDRESSES, namespace=NAMESPACE, ak="{ak}", sk="{sk}")

# get config
data_id = "python_project.json"
group = "dev"
print(client.get_config(data_id, group))
nacos_data = eval(client.get_config(data_id, group))


password = nacos_data["password"]
print("password is", password)

def test_cb(args):
    print("nacos配置发生变化")
    global password
    nacos_data = eval(client.get_config(data_id, group))
    password = nacos_data["password"]

# 注册服务
a = client.add_naming_instance("changyu_test1", "www.baidu.com", 80)
print(a)


# 发现服务
b = client.list_naming_instance("changyu_test1")
print(b)
print("ip", b["hosts"][0]["ip"])
print("port", b["hosts"][0]["port"])

if __name__ == '__main__':
    # 配置变化的监听
    client.add_config_watcher(data_id, group, test_cb)
    import time

    time.sleep(10000)
