How to use dht.PutValue? #830

Closed cpeliciari closed 1 year ago

cpeliciari commented 1 year ago

I'm trying to create a p2p network without having to use the ipfs network, when doing a put I am not getting it, here is a snippet of the code.

    host, err := libp2p.New(
        libp2p.ListenAddrs(sourceMultiAddr),
        libp2p.Identity(prvKey),
        libp2p.EnableRelay(),
    )
    if err != nil {
        log.Fatalf("Error creating host: %v", err)
    }

    dhtOptions := []dht.Option{
        dht.Mode(dht.ModeServer),
        dht.ProtocolPrefix("/test"),
    }

    dht, err := dht.New(ctx, host, dhtOptions...)
    if err != nil {
        log.Fatalf("Error creating DHT: %v", err)
    }

    value := []byte("Hello World")

    hash, _ := multihash.Sum(value, multihash.SHA2_256, -1)

    cid := cid2.NewCidV1(cid2.Raw, hash)

    err = dht.PutValue(ctx, "/ipns/"+cid.String(), value)
    if err != nil {
        log.Infof("Error putting value in DHT: %v", err)
    }

  1. Can you please give more details?
  2. What error are you getting?
  3. What are you trying to achieve exactly?

  1. I am setting up a cluster where the DHT.MODESERVER will be, the cluster will send the files to DHT, and the clients will operate the DHT.modeclient, when a customer makes a Get on the network for some file I want to get it a put To inform you that you also have that file.
  2. record could not be unmarshalled
  3. Set up a P2P network without using the IPFS network to store
