Querying Cluster Access Information

Function

This API is used to query the cluster access information. The cluster ID must comply with the Kubernetes UUID format rules, and you must have the permission to query the corresponding cluster. Otherwise, the authentication fails. The agent certificate can be downloaded only once. This API is only used to query the access information of third-party clusters. If a CCE cluster ID is transferred, 400 will be returned.
