功能介绍

获取数仓分层信息

调用方法

请参见如何调用API

URI

GET /v1/{project_id}/design/data-layers

表1 路径参数

参数

是否必选

参数类型

描述

project_id

String

项目ID,获取方法请参见项目ID和账号ID

表2 Query参数

参数

是否必选

参数类型

描述

limit

Integer

每页查询条数,即查询Y条数据。默认值50,取值范围[1,100]。

offset

Integer

查询起始坐标,即跳过X条数据,仅支持0或limit的整数倍,不满足则向下取整,默认值0。

请求参数

表3 请求Header参数

参数

是否必选

参数类型

描述

X-Auth-Token

String

IAM Token,通过调用IAM服务获取用户Token接口获取(响应消息头中X-Subject-Token的值)

workspace

String

工作空间ID,获取方法请参见实例ID和工作空间ID

X-Project-Id

String

项目ID,获取方法请参见项目ID和账号ID

多project场景采用AK/SK认证的接口请求,则该字段必选。
