Hi, guys, When I port hypervisor extension into Nova API v3, I found some actions doesn't follow REST principles. But I still have some doubt. So I send mail to here, hope I can get some suggestion. Let me explain why I want to change those API. For search action: https://review.openstack.org/#/c/33774/ The original search action works as: '/os-hypervisors/[filters]/search' It use part of URL as filters. So I change it as: '/os-hypervisors/search?query=[filters]' (I follow suggestion from http://www.slideshare.net/apigee/restful-api-design-second-edition#btnNext at 77 pages) For servers action: https://review.openstack.org/#/c/33775/ The original servers action works as: '/os-hypervisors/[filters]/servers' It use part of URL as filters too. So I change it as: '/os-hypervisors/[hypervisor id]/servers' And it will return all the servers that run on the specific hypervisor. If we want to finish the same task as the old servers action we can do as: hypervisors = GET /os-hypervisors/search?query=[filters] for hyper in hypervisors servers += GET /os-hypervisors/[hyper.id]/servers Welcome any comment!
