Querying Details of EVS Disks by Tag

Function

This API is used to query the details of EVS disks by tag.

Constraints

None

URI

  • URI format

    POST /v2/{project_id}/cloudvolumes/resource_instances/action

  • Parameter description

    Parameter

    Mandatory

    Description

    project_id

    Yes

    The project ID.

    For details about how to obtain the project ID, see Obtaining a Project ID.

Request

  • Request parameters

    Parameter

    Type

    Mandatory

    Description

    tags

    Array of objects

    Yes

    The key-value pairs of tags. For details, see Parameters in the tags field.

    One tag list can contain a maximum of 10 keys.

    Tag keys in a tag list must be unique.

    When multiple keys are specified in a tag list, only the disks having all specified keys are queried.

    NOTE:

    If multiple tag lists are specified in the request, only the disks that meet the requirements of the last tag list are queried.

    limit

    Integer

    No

    The number of query records.

    The value ranges from 1 to 1000, and the default value is 1000. The returned value cannot exceed this limit.

    offset

    Integer

    No

    The index location.

    The minimum value is 0, which is also the default value.

    The first record in the query result is the offset+1 record that meets the query criteria.

    action

    String

    Yes

    The operation identifier.

    Specifying filter queries the details of disks by tag.

    matches

    Array of objects

    No

    The query criteria that the resource supports. For details, see Parameters in the matches field.
