Function¶

This API is used to query resources of a tenant by tag.

URI¶

POST /v1/{project_id}/{resource_type}/resource_instances/action

Table 1 describes parameters in this URI.

**Table 1** URI parameters¶
Parameter	Mandatory	Type	Description
project_id	Yes	String	Specifies the project ID. For details about how to obtain the project ID, see Obtaining a Project ID.
resource_type	Yes	String	Specifies the resource type, which can be endpoint_service or endpoint.

Request¶

Parameter description

**Table 2** Request parameters¶
Parameter	Mandatory	Type	Description
tags	No	List<tag>	Lists tags that are included. Each resource to be queried contains a maximum of 20 keys. Each tag key can have a maximum of 10 tag values. The tag value corresponding to each tag key can be an empty array but the structure cannot be missing. Each tag key and each value of the same tag key must be unique. The response returns resources containing all tags in this list. Keys in this list are in an AND relationship while values in each key-value structure are in an OR relationship. If no tag filtering condition is specified, full data is returned.
tags_any	No	List<tag>	Lists any tags that are included. Each resource to be queried contains a maximum of 20 keys. Each tag key can have a maximum of 10 tag values. The tag value corresponding to each tag key can be an empty array but the structure cannot be missing. Each tag key and each value of the same tag key must be unique. The response returns resources containing the tags in this list. Keys in this list are in an OR relationship and values in each key-value structure are also in an OR relationship. If no tag filtering condition is specified, full data is returned.
not_tags	No	List<tag>	Lists tags that are not included. Each resource to be queried contains a maximum of 20 keys. Each tag key can have a maximum of 10 tag values. The tag value corresponding to each tag key can be an empty array but the structure cannot be missing. Each tag key and each value of the same tag key must be unique. The response returns resources containing no tags in this list. Keys in this list are in an AND relationship while values in each key-value structure are in an OR relationship. If no tag filtering condition is specified, full data is returned.
not_tags_any	No	List<tag>	Lists any tags that are not included. Each resource to be queried contains a maximum of 20 keys. Each tag key has a maximum of 10 tag values. The tag value corresponding to each tag key can be an empty array but the structure cannot be missing. Each tag key and each value of the same tag key must be unique. The response returns resources containing no tags in this list. Keys in this list are in an AND relationship while values in each key-value structure are in an OR relationship. If no tag filtering condition is specified, full data is returned.
limit	No	String	Sets the page size. This parameter is unavailable when action is set to count. The default size is 1000 when action is set to filter. The maximum value is 1000, and the minimum size is 1. The size cannot be a negative number.
offset	No	String	Specifies the index position. This parameter is unavailable when action is set to count. If offset is set to N, the resource query starts from the N+1 piece of data. If action is set to filter, offset is 0 by default, indicating that the query starts from the first piece of data. offset must be a positive number.
action	Yes	String	Specifies the operation to perform. The operation can only be filter (filtering) or count (querying the total number). If action is set to filter, the query is performed based on the filter conditions. If action is set to count, only the total number of records is returned.
matches	No	List<match>	Specifies the search field. The tag key is the field to be matched, for example, resource_name. value indicates the matched value. The key is a fixed dictionary value and cannot contain duplicate keys or unsupported keys. Check whether fuzzy match is required based on the key value. For example, if key is set to resource_name, fuzzy search (case-insensitive) is performed by default. If value is empty, exact match is performed. Most services do not have resources without names. In this case, an empty list is returned. If key is resource_id, exact match is used. Only resource_name for key is supported. Other key values will be available later.

**Table 3** Description of field **tag**¶
Parameter	Mandatory	Type	Description
key	Yes	String	Specifies the tag key. Each tag key contains a maximum of 127 unicode characters but cannot be left blank. The system does not verify the character set of key when searching for resources. key cannot be empty, an empty string, or spaces. Before using key, delete single-byte character (SBC) spaces before and after the value.
values	Yes	List<String>	Specifies the tag value list. Each value contains a maximum of 255 Unicode characters. Before using values, delete SBC spaces before and after the value. The value can be an empty array but cannot be left blank. If the values are null, it indicates any_value (querying any value). The values are in the OR relationship. The system does not verify the character set of values when searching for resources, but only verifies the length.

**Table 4** Description of field **match**¶
Parameter	Mandatory	Type	Description
key	Yes	String	Specifies the tag key. Only resource_name for key is supported. Other key values will be available later.
value	Yes	String	Specifies the tag value. Each value contains a maximum of 255 Unicode characters. The character set of value is not verified.
