查看作业的上下游依赖关系 - ShowFactoryJobDependInstances

功能介绍

提供对外接口,查看作业的上下游依赖关系及责任人。

调用方法

请参见如何调用API

授权信息

账号具备所有API的调用权限,如果使用账号下的IAM用户调用当前API,该IAM用户需具备调用API所需的权限。

  • 如果使用角色与策略授权,具体权限要求请参见权限和授权项
  • 如果使用身份策略授权,当前API调用无需身份策略权限。

URI

GET /v2/{project_id}/factory/jobs/{job_name}/depend

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

job_name

String

作业名称。指定要查询上下游依赖关系的目标作业名称。

作业名称在创建作业时由用户指定,可通过“查询作业列表”接口获取。

表2 Query参数

参数

是否必选

参数类型

描述

relation

String

查询的依赖方向。用于指定查询作业的直接上游、直接下游或同时查询上下游关系。

取值范围:

  • parent:查询直接上游作业,即当前作业依赖的作业。

  • child:查询直接下游作业,即依赖当前作业的作业。

  • both:同时查询直接上游和直接下游作业。

默认取值:both

请求参数

表3 请求Header参数

参数

是否必选

参数类型

描述

workspace

String

工作空间ID,获取方法请参见实例ID和工作空间ID

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,最小长度:0,最大长度:4096。

X-Project-Id

String

project_id,项目编号。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。

响应参数

状态码:200

表4 响应Body参数

参数

参数类型

描述

job_name

String

依赖的作业名称。

job_path

String

依赖的作业所在目录路径。作业在根目录下返回“/”。

depend_layer

String

当前作业与查询目标作业的依赖关系方向。

取值范围:

  • parent:当前作业是查询目标作业的上游作业。

  • child:当前作业是查询目标作业的下游作业。

workspace_name

String

依赖的作业所在的工作空间名称。

owner

String

作业责任人。创建作业时指定的作业负责人。

状态码:400

表5 响应Body参数

参数
