示例1: startListening

// startListening on the network addresses
func startListening(ctx context.Context, host p2phost.Host, cfg *config.Config) error {
	listenAddrs, err := listenAddresses(cfg)
	if err != nil {
		return err
	}

	// make sure we error out if our config does not have addresses we can use
	log.Debugf("Config.Addresses.Swarm:%s", listenAddrs)
	filteredAddrs := addrutil.FilterUsableAddrs(listenAddrs)
	log.Debugf("Config.Addresses.Swarm:%s (filtered)", filteredAddrs)
	if len(filteredAddrs) < 1 {
		return fmt.Errorf("addresses in config not usable: %s", listenAddrs)
	}

	// Actually start listening:
	if err := host.Network().Listen(filteredAddrs...); err != nil {
		return err
	}

	// list out our addresses
	addrs, err := host.Network().InterfaceListenAddresses()
	if err != nil {
		return err
	}
	log.Infof("Swarm listening at: %s", addrs)
	return nil

示例2: bootstrapRound

func bootstrapRound(ctx context.Context, host host.Host, cfg BootstrapConfig) error {

	ctx, cancel := context.WithTimeout(ctx, cfg.ConnectionTimeout)
	defer cancel()
	id := host.ID()

	// get bootstrap peers from config. retrieving them here makes
	// sure we remain observant of changes to client configuration.
	peers := cfg.BootstrapPeers()

	// determine how many bootstrap connections to open
	connected := host.Network().Peers()
	if len(connected) >= cfg.MinPeerThreshold {
		log.Event(ctx, "bootstrapSkip", id)
		log.Debugf("%s core bootstrap skipped -- connected to %d (> %d) nodes",
			id, len(connected), cfg.MinPeerThreshold)
		return nil
	}
	numToDial := cfg.MinPeerThreshold - len(connected)

	// filter out bootstrap nodes we are already connected to
	var notConnected []peer.PeerInfo
	for _, p := range peers {
		if host.Network().Connectedness(p.ID) != inet.Connected {
			notConnected = append(notConnected, p)
		}
	}

	// if connected to all bootstrap peer candidates, exit
	if len(notConnected) < 1 {
		log.Debugf("%s no more bootstrap peers to create %d connections", id, numToDial)
		return ErrNotEnoughBootstrapPeers
	}

	// connect to a random susbset of bootstrap candidates
	randSubset := randomSubsetOfPeers(notConnected, numToDial)

	defer log.EventBegin(ctx, "bootstrapStart", id).Done()
	log.Debugf("%s bootstrapping to %d nodes: %s", id, numToDial, randSubset)
	if err := bootstrapConnect(ctx, host, randSubset); err != nil {
