Thanks for the PR @yanjunding!

For the code organization, it probably makes sense to combine this with the previous if check. Feel free to do that or I can do it in a follow up PR :)

Had a quick look at the health Response, shall we check Respdoby == nil, instead of checking err == nil?

The response should be returned as long as the response Body is not nil, including all return status
