Best practice in following scenario: In my func for an endpoint (handler) with func hello(w http.ResponseWriter, req *http.Request) I call another server get the resp.Body (Body io.ReadCloser) and want to write this Body in w (ResponseWriter ). What is best practice? I have already copied directly Body to w via io.Copy. I want but make sure that the whole body is sent to client. With io.Copy I am not sure if this is guaranteed. And I would like to set status to 500 in case io.Copy returns err.
Could you please help me on this? -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
