查询ACL资源实例数量

功能介绍

使用标签过滤查询ACL实例数量。

调用方法

请参见如何调用API

URI

POST /v3/{project_id}/firewalls/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

请求参数

表2 请求Body参数

参数

是否必选

参数类型

描述

matches

Array of Match objects

功能说明:搜索字段,key为要匹配的字段,value为匹配的值

约束:key为固定字典值,不能包含重复的key或不支持的key,当前key仅支持resource_name

tags

Array of ListTag 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3 Match

参数

是否必选

参数类型

描述

key

String

键。当前仅限定为resource_name

最小长度:1

最大长度:128

value

String

值。每个值最大长度255个unicode字符.

最小长度:0

最大长度:255

表4 ListTag

参数

是否必选

参数类型

描述

key

String

功能说明:标签键

约束:key不能为空

最小长度:1

最大长度:128

values

Array of strings

功能描述:标签值列表。

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。

最大长度:255

状态码:200

表5 响应Body参数

参数

参数类型

描述

request_id

String

请求ID

total_count

Integer

资源数量

请求示例
