Question

我无法使用@hashgraph/SDK hedera传输NFT。如何使用@哈希图/SDK的内置方法传输nft？

另外，Nft已经与卖方帐户相关联。

此外，我正在传输令牌，这是在hashpack nft部分可用的。

在调用TransferTransaction方法@hashgraph/sdk@2.17.1时，我会得到以下错误。代码：

  const TransferNft = async (tokenId, sellerAccount, sellerId, buyerAccount, buyerId) => {
  try {
    const client = await getClient();

    tokenId = TokenId.fromString(tokenId);

    let sellerKey = await getPrivateKey(sellerId);
    sellerKey = PrivateKey.fromString(sellerKey);

    let buyerKey = await getPrivateKey(buyerId);
    buyerKey = PrivateKey.fromString(buyerKey);

    // 2nd NFT TRANSFER NFT Alice->Bob
    let tokenTransferTx2 = await new TransferTransaction()
      .addNftTransfer(tokenId, 2, sellerAccount, buyerAccount)
      .addHbarTransfer(sellerAccount, Hbar.fromTinybars(100))
      .addHbarTransfer(buyerAccount, Hbar.fromTinybars(-100))
      .freezeWith(client)
      .sign(sellerKey);
    let tokenTransferTx2Sign = await tokenTransferTx2.sign(buyerKey);
    let tokenTransferSubmit2 = await tokenTransferTx2Sign.execute(client);
    let tokenTransferRx2 = await tokenTransferSubmit2.getReceipt(client);
    console.log(`\n NFT transfer Alice->Bob status: ${tokenTransferRx2.status} \n`);

    return tokenTransferRx2.status;
  } catch (error) {
    console.log('Error in HederaToken/TransferNft/TransferNft: \n', error)
  }
};

在不属于HTS令牌的帐户接收或发送特定令牌ID之前，它们必须与令牌“关联”--这有助于减少来自不希望与Hedera网络上创建的任意令牌相关联的用户的垃圾邮件和其他关注。

帐户和令牌ID之间的这种关联可以通过手动或自动两种方式完成。请注意，可以对现有帐户和新创建的帐户进行自动关联。

下面是通过帐户更新对现有帐户进行自动关联的方法：

 // AUTO-ASSOCIATION FOR ALICE'S ACCOUNT
    let associateTx = await new AccountUpdateTransaction()
        .setAccountId(aliceId)
        .setMaxAutomaticTokenAssociations(100)
        .freezeWith(client)
        .sign(aliceKey);
    let associateTxSubmit = await associateTx.execute(client);
    let associateRx = await associateTxSubmit.getReceipt(client);
    console.log(`Alice NFT Auto-Association: ${associateRx.status} \n`);

下面是如何对现有帐户进行手动关联：

// MANUAL ASSOCIATION FOR BOB'S ACCOUNT
let associateBobTx = await new TokenAssociateTransaction()
    .setAccountId(bobId)
    .setTokenIds([tokenId])
    .freezeWith(client)
    .sign(bobKey);
let associateBobTxSubmit = await associateBobTx.execute(client);
let associateBobRx = await associateBobTxSubmit.getReceipt(client);
console.log(`Bob NFT Manual Association: ${associateBobRx.status} \n`);
