Configuration Management

Get configurations

Description

This API is used to get configurations in Nacos.

Request type

GET

Request URL

/nacos/v1/cs/configs

Request parameters

Return parameters

Error codes

Example

• Request example

  curl -X GET 'http://127.0.0.1:8848/nacos/v1/cs/configs?dataId=nacos.example&group=com.alibaba.nacos'

• Return example

  contentTest

Listen for configurations

Description

This API is used to listen for configurations in Nacos to capture configuration changes. In case of any configuration changes, you can use the Get Configurations API to obtain the latest value of the configuration and dynamically refresh the local cache.

A listener is registered using an asynchronous servlet. The nature of registering a listener is to compare the configuration value and the MD5 value of it with that of the backend. If the values differ, the inconsistent configuration is returned immediately. Otherwise, an empty string is returned after 30 seconds.

Request type

POST

Request URL

/nacos/v1/cs/configs/listener

Request parameters

Header parameters

Parameter description

• A delimiter to separate fields within a configuration: ^2 = Character.toString((char) 2
• A delimiter to separate configurations: ^1 = Character.toString((char) 1)
• contentMD5: MD5(content). This is an empty string because the first local cache is empty.

Return parameters

Error codes

Example

• Request example

http://serverIp:8848/nacos/v1/cs/configs/listener
POST request body data:
