使用标签过滤资源（通道等）

功能介绍

该接口用于使用标签过滤资源（通道等）。

调用方法

请参见如何调用API。

URI

POST /v2/{project_id}/stream/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

项目ID。

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

是

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

action

是

String

操作标识(仅限于filter，count)

  • filter：分页查询

  • count：查询总条数，只需按照条件将总条数返回即可

枚举值：

  • filter

  • count

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

缺省值：1000

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

tags

否

Array of Tags objects

返回结果包含该参数中所有标签对应的资源，该参数最多包含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。

tags_any

否

Array of Tags objects

返回结果包含该参数中任意一个标签对应的资源，该参数最多包含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。

not_tags

否

Array of Tags objects

返回结果不包含该参数中所有标签对应的资源，该参数最多包含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。

not_tags_any

否

Array of Tags objects

返回结果不包含该参数中任意一个标签对应的资源，该参数最多包含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。

matches

  • 对于同一资源键值唯一。

  • 字符集：A-Z，a-z ， 0-9，‘-’，‘_’，UNICODE字符（\u4E00-\u9FFF）。

最大长度：36

values

否

Array of strings

标签值列表。

如果values为空列表，则表示any_value。value之间为或的关系。
