查询目的表和字段(待下线)

功能介绍

查询目的表和字段(待下线)。

调用方法

请参见如何调用API

URI

GET /v2/{project_id}/design/{model_id}/table-model/relation/fields

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

model_id

String

所属关系建模的模型ID,ID字符串。model_id可从接口获取模型中获取。

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)

使用Token认证时必选。

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。

Content-Type

String

默认值:application/json;charset=UTF-8

可选,有Body体的情况下必选,没有Body体则无需填写和校验。
