我正在尝试使用 bitcoinj 0.14.7 解码 testnet 交易。这是我试图解码的交易的十六进制：

02000000000101ef4c1c3c60028b050a5798265c0b37719418dd71b0621e76a68a47d5d9eef55f000000001716001467d7c32c0dad98bf8dd3dea81cbb1dbd4ea4afb5feffffff02b7df02000000000017a914ebb55a85454dc15589b8a87bab4b438892b54c0c87b0ad0100000000001976a914140b85a1c430c8f4fd1f91ae1c7451902b8ce76c88ac024730440220359623836f97e9e4c04917455ed2f9fb2343b0bf96853d47313b0c96d828c889022046da37bfda03cf3481e3ef5c5b5e655d6fd280c2aec2831b6494a8207b76655b01210224c44e1af98b5c28ebf822b65e4a2872d0780b4b6935b3100f60d3ac3b78cb00b2f81500

当我去块密码https://live.blockcypher.com/btc/decodetx/并在那里解码交易时 - 它被解码没问题。但是当我试图这样做时：

Transaction tx = new Transaction(params, HexUtils.hexToBytes(txHex));
LOGGER.info(tx.toString());

它打印

4c67f1e1b10b063210e59400466383fb18634c05430d4f53795a16216dd34ffd

另外，我对照 master 检查了我的代码，它的措辞就像一个魅力！这是输出：

您的代码只是创建一个事务对象，所以这还不够。

您的要求是从块中获取交易。所以你需要连接一个测试网节点。只需创建一个 PeerGroup 连接本地或远程比特币测试网节点。

检查下面的示例。

    final NetworkParameters params = TestNet3Params.get();

    BlockStore blockStore = new MemoryBlockStore(params);
    BlockChain chain = new BlockChain(params, blockStore);
    PeerGroup peerGroup = new PeerGroup(params, chain);
    peerGroup.start();
    // Alternatively you can connect your localhost or another working testnet node
    peerGroup.addAddress(new PeerAddress(params, "testnet-seed.bitcoin.jonasschnelli.ch", 18333));
    peerGroup.waitForPeers(1).get();
    Peer peer = peerGroup.getConnectedPeers().get(0);

    Sha256Hash txHash = Sha256Hash.wrap(hexString);
    ListenableFuture<Transaction> future = peer.getPeerMempoolTransaction(txHash);
    System.out.println("Waiting for node to send us the requested transaction: " + txHash);
    Transaction tx = future.get();
    System.out.println(tx);
