As per the doc¹: If the returned error is nil, the Response will contain a non-nil Body which the user is expected to close. ... On error, any Response can be ignored. A non-nil Response with a non-nil error only occurs when CheckRedirect fails, and even then the returned Response.Body is already closed. It is thus safe to defer res.Body.Close() as soon as err has been determined to be nil. Also, I've dispensed with the separate variable client, since it is not used later. ¹: https://godoc.org/net/http#Client.Do
