功能介绍

按照标签检索子资源数量

接口约束

调用方法

请参见如何调用API

URI

POST /v2/{project_id}/{resource_type}/{resource_id}/{sub_resource_type}/resource-instances/count

表1 路径参数

参数

是否必选

参数类型

描述

project_id

String

项目ID

resource_type

String

资源类型,支持的资源类型为:instances

resource_id

String

资源id

sub_resource_type

String

子资源类型,支持的子资源类型为:namespaces

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(响应消息头中X-Subject-Token的值)。

表3 请求Body参数

参数

是否必选

参数类型

描述

tags

Array of TagsFilter objects

包含标签,最多包含50个key,每个key下面的value最多10个,每个key对应的value可以为空数组但结构体不能缺失。Key不能重复,同一个key中values不能重复。结果返回包含所有标签的资源列表,key之间是与的关系,key-value结构中value是或的关系。无tag过滤条件时返回全量数据。

表4 TagsFilter

参数

是否必选

参数类型

描述

key

String

标签键,最大长度128个unicode字符。 key不能为空。

values

Array of strings

标签值列表,每个值最大长度255个unicode字符,校验和使用之前先trim 前后半角空格。value可为空数组但不可缺省。如果values为空列表,则表示any_value(查询任意value)。value之间为或的关系。。
