Golang MakeName Examples

Example #1

File: main.go Project: codeaudit/shift

func main() {
	logger.AddLogSystem(logger.NewStdLogSystem(os.Stdout, log.LstdFlags, logger.InfoLevel))

	// Generate the peer identity
	key, err := crypto.GenerateKey()
	if err != nil {
		fmt.Printf("Failed to generate peer key: %v.\n", err)
		os.Exit(-1)
	}
	name := common.MakeName("whisper-go", "1.0")
	shh := whisper.New()

	// Create an Shift peer to communicate through
	server := p2p.Server{
		PrivateKey: key,
		MaxPeers:   10,
		Name:       name,
		Protocols:  []p2p.Protocol{shh.Protocol()},
		ListenAddr: ":30300",
		NAT:        nat.Any(),
	}
	fmt.Println("Starting Shift peer...")
	if err := server.Start(); err != nil {
		fmt.Printf("Failed to start Shift peer: %v.\n", err)
		os.Exit(1)
	}

	// Send a message to self to check that something works
	payload := fmt.Sprintf("Hello world, this is %v. In case you're wondering, the time is %v", name, time.Now())
	if err := selfSend(shh, []byte(payload)); err != nil {
		fmt.Printf("Failed to self message: %v.\n", err)
		os.Exit(-1)
	}
}
