…ndant body reading This change adds proper signal handling by passing in a buffered signal channel to signal.Notify as it mandates at https://pkg.go.dev/os/signal#Notify It also handles non-2XX codes and reports this while printing the content and returning. While here also added resp.Body.Close() to avoid leaking HTTP responses. Also removes redundant bytes.Buffer.ReadFrom, then .String() and string(newMsg) by simply using io/ioutil.ReadAll(resp.Body) given we aren't sure which version of Go being used but really in >=Go1.16, we can use io.ReadAll Fixes danielgross#13 Fixes danielgross#14 Fixes danielgross#15 Signed-off-by: Emmanuel T Odeke <[email protected]>

There was a problem hiding this comment.
No need to, this code closes it immediately after use. A defer will keep it open until the function returns or panics and then that's when the close will happen.
