示例1: NewDHT
// NewDHT creates a new DHT object with the given peer as the 'local' host
func NewDHT(ctx context.Context, h host.Host, dstore ds.Datastore) *IpfsDHT {
dht := new(IpfsDHT)
dht.datastore = dstore
dht.self = h.ID()
dht.peerstore = h.Peerstore()
dht.host = h
// register for network notifs.
dht.host.Network().Notify((*netNotifiee)(dht))
dht.proc = goprocess.WithTeardown(func() error {
// remove ourselves from network notifs.
dht.host.Network().StopNotify((*netNotifiee)(dht))
return nil
})
dht.strmap = make(map[peer.ID]*messageSender)
dht.ctx = ctx
h.SetStreamHandler(ProtocolDHT, dht.handleNewStream)
dht.providers = providers.NewProviderManager(dht.ctx, dht.self, dstore)
dht.proc.AddChild(dht.providers.Process())

// one `Connect` call hangs, subsequent calls are more likely to
// fail/abort due to an expiring context.
// Also, performed asynchronously for dial speed.
