通过标签查询资源实例 - ListTagResourceInstances

功能介绍

通过标签查询资源实例

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

POST /v3/{project_id}/{resource_type}/resource-instances/action

表1 路径参数

参数

是否必选

参数类型

描述

project_id

是

String

租户项目ID

最小长度：0

最大长度：36

resource_type

是

String

  • 专线服务资源类型，包括dc-directconnect/dc-vgw/dc-vif

  • dc-directconnect: 专线物理连接

  • dc-vgw： 虚拟网关

  • dc-vif： 虚拟接口

请求参数

表2 请求Body参数

参数

是否必选

参数类型

描述

offset

否

String

索引位置， 从offset指定的下一条数据开始查询。 查询第一页数据时，不需要传入此参数，查询后续页码数据时，将查询前一页数据时响应体中的值带入此参数（action为count时无此参数）如果action为filter默认为0,必须为数字，不能为负数

limit

否

String

查询记录数（action为count时无此参数）如果action为filter默认为1000，limit最多为1000,不能为负数，最小值为1

action

是

String

操作标识（仅限于filter，count）：filter（过滤），count(查询总条数)

如果是filter就是分页查询，如果是count只需按照条件将总条数返回即可。禁止返回其他字段。

matches

否

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。此字段为固定字典值。根据不同的字段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。resource_id为精确匹配。第一期只做resource_name，后续再扩展。

not_tags

否

Array of Tags objects

不包含标签，最多包含10个key，每个key下面的value最多10个, 结构体不能缺失，key不能为空或者空字符串。Key不能重复，同一个key中values不能重复。返回不包含标签的资源列表，key之间是与的关系，key-value结构中value是或的关系。无过滤条件时返回全量数据。

tags

否

Array of Tags objects

包含标签，最多包含10个key，每个key下面的value最多10个，结构体不能缺失，key不能为空或者空字符串。Key不能重复，同一个key中values不能重复。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。

tags_any

否

Array of Tags objects

包含任意标签，最多包含10个key，每个key下面的value最多10个,结构体不能缺失，key不能为空或者空字符串。Key不能重复，同一个key中values不能重复。返回包含标签的资源列表，key之间是或的关系，key-value结构中value是或的关系。无过滤条件时返回全量数据。

not_tags_any

否

Array of Tags objects

不包含任意标签，最多包含10个key，每个key下面的value最多10个,结构体不能缺失，key不能为空或者空字符串。Key不能重复，同一个key中values不能重复。返回不包含标签的资源列表，key之间是或的关系，key-value结构中value是或的关系。无过滤条件时返回全量数据。

sys_tags

否

Array of Tags 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_id，value：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。
表3 Match
