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. Tag keys in a list must be unique.

Parameters in the tags field

Parameter	Type	Mandatory	Description
key	String	Yes	The tag key.
values	Array of objects	Yes	The tag value. One value list can contain a maximum of 10 values. Tag values in a value list must be unique. If the value list is left empty, any tag value can be matched. When multiple values are specified in a value list and the key requirements are met, disks that have any of the specified values are queried.

Parameter

Type

Mandatory

Description

key

String

Yes

The tag key.

values

Array of objects

Yes

The tag value.

One value list can contain a maximum of 10 values.
Tag values in a value list must be unique.
If the value list is left empty, any tag value can be matched. When multiple values are specified in a value list and the key requirements are met, disks that have any of the specified values are queried.

Parameters in the matches field

Parameter	Type	Mandatory	Description
key	String	Yes	The tag key. The value can be as follows: resource_name: the disk name service_type: the service type
value	String	Yes	The tag value. It can contain up to 255 characters. If resource_name is specified for key, the tag value uses a fuzzy match. If service_type is specified for key, the value can be EVS and is case-insensitive.

Parameter

Type

Mandatory

Description

key

String

Yes

The tag key.

The value can be as follows:

resource_name: the disk name
service_type: the service type

value

String

Yes

The tag value.

It can contain up to 255 characters.
If resource_name is specified for key, the tag value uses a fuzzy match.
If service_type is specified for key, the value can be EVS and is case-insensitive.
