查询资源实例数量 - CountResourceInstance

功能介绍

使用标签过滤实例,查询资源实例数量

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,具体权限要求请参见权限和授权项

URI

POST /v1/{project_id}/{resource_type}/resource-instances/count

表1 路径参数

参数

是否必选

参数类型

描述

resource_type

String

资源类型

project_id

String

参数解释:

项目ID,用于明确项目归属,配置后可通过该ID查询项目下资产,可以通过调用API获取,也可以从控制台获取。获取项目ID

约束限制:

不涉及

取值范围:

不涉及

默认取值:

不涉及

请求参数

表2 请求Header参数

参数

是否必选

参数类型

描述

Content-type

String

参数解释:

内容类型

  • application/json;charset=UTF-8 普通API请求的类型

约束限制:

不涉及

取值范围:

  • application/json;charset=UTF-8

默认取值:

不涉及

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

without_any_tag

Boolean

不包含任意一个标签,该字段为true时查询所有不带标签的资源,此时忽略 “tags”、“tags_any”、“not_tags”、“not_tags_any”字段。

tags

Array of WorkspaceTag 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。

sys_tags

Array of WorkspaceTag objects

仅op_service权限可以使用此字段做资源实例过滤条件。目前TMS调用时只包含一个tag结构体。key:_sys_enterprise_project_idvalue:企业项目id列表目前TMS调用时,key下面只包含一个value。0表示默认企业项目sys_tags和租户标签过滤条件(without_any_tag 、tags、tags_any、not_tags、not_tags_any)不能同时使用无sys_tags时按照tag接口处理,无tag过滤条件时返回全量数据。

matches

Array of Match objects

搜索字段,key为要匹配的字段,如resource_name等。value为匹配的值。key为固定字典值,不能包含重复的key或不支持的key。根据key的值确认是否需要模糊匹配,如resource_name默认为模糊搜索(不区分大小写),如果value为空字符串精确匹配(多数服务不存在资源名称为空的情况,因此此类情况返回空列表)。resource_id为精确匹配。第一期只做resource_name,后续再扩展。

表4 WorkspaceTag

参数

是否必选

参数类型

描述

key

String

键。最大长度128个unicode字符。 key不能为空。(搜索时不对此参数做字符集校验),key不能为空或者空字符串,不能为空格,校验和使用之前先trim 前后半角空格。

values

Array of strings

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。

表5 Match

参数

是否必选

参数类型

描述

key

String

键。第一期限定为resource_name,后续扩展。

value

String

值。每个值最大长度255个unicode字符。
