POST /v3/{project_id}/instances/{instance_id}/proxy/{proxy_id}/new-node-auto-add

表1 路径参数

参数

是否必选

参数类型

描述

project_id

String

租户在某一Region下的project ID。

获取方法请参见获取项目ID

instance_id

String

实例ID,严格匹配UUID规则。

proxy_id

String

数据库代理ID,严格匹配UUID规则。

请求参数

表2 请求Header参数

参数

是否必选

参数类型

描述

X-Auth-Token

String

用户Token。

通过调用IAM服务获取用户Token接口获取。
