Request Parameters
Parameter |
Mandatory |
Type |
Description |
---|---|---|---|
matches |
No |
Array of Match objects |
The key-value pair to be matched in the query. The key is a fixed dictionary value and must be a unique and supported key. The key can only be resource_name. |
tags |
No |
Array of ListTag objects |
The resources to be queried contain all tags listed in tags. A maximum of 50 tags can be specified. Each tag key can have a maximum of 10 tag values. Each tag value can be an empty array but the structure cannot be missing. Each tag key must be unique, and each tag value of a tag must also be unique. Resources with all tags listed in tags will be returned. Keys in this list are in an AND relationship while values in each key-value structure are in an OR relationship. If tags is not specified, all resources will be returned. |
Response Parameters
