[go-nuts] How to read a JSON Response body

For JSON responses, is it more appropriate to use json.Unmarshal(resp.Body, ) or json.NewDecoder(resp.Body).Decode() or b, _ := ioutil.ReadAll(resp.Body) json.Unmarshal(b, ) What are the uses for each? Does this differ from how you would read non-JSON responses? -- You received this
