Querying Private NAT Gateways

Function

This API is used to query private NAT gateways by tag.
Tag Management Service (TMS) uses this API to filter and list private NAT gateways by tag.

Calling Method

For details, see Calling APIs.

URI

POST /v3/{project_id}/private-nat-gateways/resource_instances/action

**Table 1** Path Parameters
Parameter	Mandatory	Type	Description
project_id	Yes	String	Specifies the project ID.

Request Parameters

**Table 2** Request header parameters
Parameter	Mandatory	Type	Description
X-Auth-Token	Yes	String	Specifies the user token. It is a response to the API for obtaining a user token. This API is the only one that does not require authentication. The value of X-Subject-Token in the response header is the token value.

**Table 3** Request body parameters
Parameter	Mandatory	Type	Description
offset	No	String	Specifies the index position. The query starts from the next data record indexed by this parameter. When querying resources on the first page, you do not need to specify this parameter. When querying resources on subsequent pages, set this parameter to the value returned in the response body for querying resources on the previous page. This parameter is not available when action is set to count. If action is set to filter, the value must be a positive number, and the default value is 0.
limit	No	String	Specifies the number of records to be queried. This parameter is not available when action is set to count. If action is set to filter, the default value is 1000, which is also the maximum value. The minimum value is 1. The value cannot be a negative number.
action	Yes	String	Specifies the operation to be performed. The value can 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.
matches	No	Array of Match objects	Specifies the search field. The tag key is the field to be matched, for example, resource_name. The tag value indicates the value to be matched. This field is a fixed dictionary value. You can determine whether fuzzy match is required based on different fields. For example, if key is set to resource_name, fuzzy search (case insensitive) is used by default. If value is an empty string, exact match is used. If key is set to resource_id, exact match is used. Currently, only resource_name is supported.
not_tags	No	Array of Tags objects	The resources to be queried do not contain tags listed in not_tags. Each resource to be queried contains a maximum of 20 keys. Each tag key can have a maximum of 20 tag 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 in a tag must be unique.Resources that do not contain the tags listed in not_tags will be returned.Keys are in AND relationship, and values in a tag are in OR relationship.If this parameter is not specified, all resources will be returned.
tags	No	Array of Tags objects	The resources to be queried contain tags listed in tags. Each resource to be queried contains a maximum of 20 keys. Each tag key can have a maximum of 20 tag 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 in a tag must be unique.Resources that contain the tags listed in *tags will be returned.Keys are in AND relationship, and values in a tag are in OR relationship.If this parameter is not specified, all resources will be returned.
tags_any	No	Array of Tags objects	The resources to be queried contain any tag listed in tags_any. Each resource to be queried contains a maximum of 20 keys. Each tag key can have a maximum of 20 tag 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 in a tag must be unique.Resources that contain any tag listed in *tags_any will be returned.Keys are in AND relationship, and values in a tag are in OR relationship.If this parameter is not specified, all resources will be returned.
not_tags_any	No	Array of Tags objects	The resources to be queried do not contain any tag listed in not_tags_any. Each resource to be queried contains a maximum of 20 keys. Each tag key can have a maximum of 20 tag 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 in a tag must be unique.Resources that do not contain any tag listed in not_tags_any will be returned.Keys are in AND relationship, and values in a tag are in OR relationship.If this parameter is not specified, all resources will be returned.

**Table 4** Match
Parameter	Mandatory	Type	Description
key	Yes	String	Specifies the tag key used to search for resources.
value	Yes	String	Specifies the tag value used to search for resources.

**Table 5** Tags
Parameter	Mandatory	Type	Description
key	Yes	String	Specifies the tag key. A key can contain up to 128 Unicode characters. (The system does not verify key when searching for resources.) key cannot be left blank or be an empty string. key cannot contain spaces. Before using the value of key, delete spaces before and after the value.
values	Yes	Array of strings	Specifies the list of tag values. Each value can contain a maximum of 255 Unicode characters and cannot contain spaces. Before verification and use, delete spaces before and after the value. The value can be an empty array but cannot be left blank. If values is not specified, any parameter value can be queried. All values of a tag key are in the OR relationship. The system verifies the length, but not the character set of values when searching for resources.

Response Parameters

Status code: 200

**Table 6** Response body parameters
Parameter	Type	Description
resources	Array of Resource objects	Specifies the resource list.
request_id	String	Specifies the request ID.
total_count	Integer	Specifies the total number of records.

**Table 7** Resource
Parameter	Type	Description
resource_detail	Object	Specifies the resource details. This parameter is used for extension and is left blank by default.
resource_id	String	Specifies the resource ID.
resource_name	String	Specifies the resource name. This parameter is an empty string by default if there is no resource name.
resource_tag	Array of ResourceTag objects	Specifies the list of queried tags. If no tag is matched, an empty array is returned.

**Table 8** ResourceTag
Parameter	Type	Description
key	String	Specifies the tag key.
value	String	Specifies the tag value.
