Multiple values can be used for query in the format of: enterprise_project_id=xxx&enterprise_project_id=xxx. Constraints: If enterprise_project_id is not specified, resources in all enterprise projects are queried by default. Fine-grained authorization is performed. The elb:l7rules:list permission must be assigned to the user group. If enterprise_project_id is specified, the value can be a specific enterprise project ID or all_granted_eps. If the value is a specific enterprise project ID, only resources in the enterprise project are queried. If the value is all_granted_eps, resources in the enterprise projects with the elb:l7rules:list permission are queried. Range: N/A Default value: N/A
