https://nacos.io/en-us/docs/open-api.html

```shell
# https://nacos.io/en-us/docs/v2/guide/user/auth.html
# login to get accessToken
curl -X POST '127.0.0.1:8848/nacos/v1/auth/login' -d 'username=nacos&password=nacos'
-- get all namespaces do not need login
curl -X GET "http://nacos-server:8848/nacos/v1/console/namespaces"

-- page query configurations in namespace xxx
-- this url is obtained from nacos console page
curl -X GET "http://nacos-server:8848/nacos/v1/cs/configs?dataId=&group=&appName=&config_tags=&pageNo=1&pageSize=10&tenant=NAMESPACE_ID&search=accurate&accessToken=TOKEN&username=USERNAME"
```

## springboot+nacos

在springboot+nacos应用中配置app_ip，便于在nacos管理端看到服务的ip，灰度发布时很有用。两种方式。适用于任何应用。

```text
-Dspring.cloud.nacos.discovery.metadata.app_ip=121.40.178.113

--spring.cloud.nacos.discovery.metadata.app_ip=121.40.178.113
```
