Querying Resources by Tag

Function

This API is used to query resources by tag.

Debugging

For details, see Calling APIs.

URI

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

Table 1 Path parameters

Parameter

Mandatory

Type

Description

project_id

Yes

String

Specifies the project ID.

resource_type

Yes

String
  • Specifies the Direct Connect resource type. The value can be dc-directconnect, dc-vgw, or dc-vif.
  • dc-directconnect: Direct Connect connection
  • dc-vgw: virtual gateway
  • dc-vif: virtual interface

Enumeration values:

  • dc-directconnect
  • dc-vgw
  • dc-vif

Request Parameters

Table 2 Request body parameters

Parameter

Mandatory

Type

Description

offset

No

String

Specifies the index position. The query starts from the next image indexed by this parameter. This parameter is not required when you query data on the first page. The value in the response returned for querying data on the previous page will be included in this parameter for querying data on subsequent pages. This parameter is not available when action is set to count. If action is set to filter, the value must be a number, and the default value is 0. The value cannot be a negative number.

limit

No

String

Number of records. This parameter is not available when action is set to count. The default value is 1000 when action is set to filter. The maximum value is 1000, and the minimum value is 1. The value cannot be a negative number.

action

Yes

String

The value can only be filter or count. The value filter indicates pagination query. The value count indicates that the total number of query results meeting the search criteria will be returned. Returning other fields is not allowed.

Enumeration values:

  • filter
  • count

matches

No

Array of Match objects

Specifies the search criteria. The tag key is the parameter to match, for example, resource_name. The tag value indicates the value to be matched. This field is a fixed dictionary value. Determine whether fuzzy match is required based on different fields. For example, if key is resource_name, fuzzy search (case insensitive) is used by default. If value is an empty string, exact match is used. If key is resource_id, exact match is used. Only resource_name is queried at the first phase, and other keys will be queried later.

not_tags

No

Array of Tags objects

Specifies the excluded tags. Each tag contains a maximum of 10 keys, and each key contains a maximum of 10 values. The structure body cannot be missing, and the key cannot be left blank or set to an empty string. Each tag key must be unique, and each tag value of a tag must also be unique. Resources not identified by different keys are in AND relationship, and values in one tag are in OR relationship. If not_tags_any is not specified, all resources will be returned.

tags

No

Array of Tags objects

A maximum of 10 keys can be queried at a time, and each key can contain a maximum of 10 values. The structure body must be included. The tag key cannot be left blank or be an empty string. Each tag key must be unique, and each tag value of a tag must also be unique. Resources identified by different keys are in AND relationship, and values in one tag are in OR relationship. If no tag filtering criteria is specified, full data is returned.

tags_any

No

Array of Tags objects

Specifies any included tags. Each tag contains a maximum of 10 keys, and each key contains a maximum of 10 values. The structure body cannot be missing, and the key cannot be left blank or set to an empty string. Each tag key must be unique, and each tag value of a tag must also be unique. Resources identified by different keys are in OR relationship, and values in one tag are in OR relationship. If not_tags_any is not specified, all resources will be returned.

not_tags_any

No

Array of Tags objects

Specifies any excluded tags. Each tag contains a maximum of 10 keys, and each key contains a maximum of 10 values. The structure body cannot be missing, and the key cannot be left blank or set to an empty string. Each tag key must be unique, and each tag value of a tag must also be unique. Resources not identified by different keys are in OR relationship, and values in one tag are in OR relationship. If not_tags_any is not specified, all resources will be returned.

sys_tags

No

Array of Tags objects

Only users with the op_service permission can use this parameter to filter resources. Only one tag structure is contained when this API is called by Tag Management Service (TMS). The key is _sys_enterprise_project_id, and the value is the enterprise project ID list. Currently, each key can contain only one value. 0 indicates the default enterprise project. sys_tags and tenant tag filtering conditions (without_any_tag, tags, tags_any, not_tags, and not_tags_any) cannot be used at the same time.
Table 3 Match

Parameter

Mandatory

Type

Description

key

Yes

String

Specifies the tag key. The value can be dc-directconnect, dc-vgw, or dc-vif.

value

Yes

String

Specifies the tag value. It can contain a maximum of 255 Unicode characters.
Table 4 Tags

Parameter

Mandatory

Type

Description

key

Yes

String

Specifies the tag key. A key can contain a maximum of 127 Unicode characters. The tag key cannot be left blank.

values

Yes

Array of strings

Lists the tag values. It can contain a maximum of 255 Unicode characters.

Response Parameters

Status code: 200

Table 5 Response body parameters

Parameter

Type

Description

resources

Array of Resource objects

Specifies the resource list.

total_count

Integer

Specifies the total number of resources.

request_id

String

Specifies the request ID.
Table 6 Resource

Parameter

Type

Description

resource_detail

Object

Provides details about the resource. The value is a resource object, used for extension. resource_detail is left blank by default.

resource_id

String

Specifies the resource ID.

resource_name

String

Resource name. This parameter is an empty string by default if there is no resource name.

tags

Array of Tag objects

Specifies the list of queried tags. If no tag is matched, an empty array is returned.

sys_tags

Array of Tag objects

Specifies the list of queried tags. If no tag is matched, an empty array is returned.
Table 7 Tag
