I don't understand why. Anyone can help about this ?
func Make(w http.ResponseWriter, r *http.Request, app App) {
runtime.GOMAXPROCS(4)
flusher, ok := w.(http.Flusher)
if !ok {
panic("expected http.ResponseWriter to be an http.Flusher")
}
w.Header().Set("X-Content-Type-Options", "nosniff")
tmpl, err := template.New("app").Parse(app.Page.Content)
if err != nil {
panic("An Error occured when parsing html")
return
}
err = tmpl.Execute(w, "")
if err != nil {
panic("Error in Template.Execute")
}
flusher.Flush()
for _, gateway := range app.Gateway {
go func(gateway Gateway) {
tmpl, err := template.New(gateway.Name).Parse(gateway.Content)
if err != nil {
panic("An Error occured when parsing html")
}
err = tmpl.Execute(w, "")
if err != nil {
panic(err)
}
defer flusher.Flush()
}(gateway)
}
}
