Obtaining the Resource Flavor List

Function

This API is used to obtain available resource specifications. It is used when you need to know the available resource specifications so that you can select proper configurations when creating or adjusting a Lite Server instance. Before using this API, ensure that you have logged in to the system and have the permission to query resource specifications. After the query, the API returns information about all available resource specifications, including the specification ID, CPU, memory, and storage. If you do not have the required permission or the system does not have available resource specifications, the API returns an error message.

Debugging

You can debug this API through automatic authentication in API Explorer or use the SDK sample code generated by API Explorer.

Authorization Information

If you are using role/policy-based authorization, see Permissions Policies and Supported Actions for details on the required permissions.
If you are using identity policy-based authorization, no identity policy-based permission required for calling this API.
