How To Make an HTTP Server in Go

Is this extra? “<^>”

Thanks for the tutorial, there appears to be an error in this text:

“One other change is adding a BaseContext function. BaseContext is a way to change parts of the context.Context that handler functions receive when they call the Context method of *http.Request. In the case of your program, you’re adding the address the server is listening on (l.Addr().String()) to the context with the key serverAddr, which will then be printed to the handler function’s output.”

the code snippet is this:

...
func main() {
	...
	mux.HandleFunc("/hello", getHello)

	ctx, cancelCtx := context.WithCancel(context.Background())
	serverOne := &http.Server{
		Addr: ":3333",
		Handler: mux,
		BaseContext: func(l net.Listener) context.Context {
			ctx = context.WithValue(ctx, keyServerAddr, l.Addr().String())
			return ctx
		},
	}

I think in the text: “… to the context with the key serverAddr…”

I bet you mean keyServerAddr there, right?
