与bitcoinj获取原始块

Question

我试图用bitcoinj获取原始块。我使用Block.bitcoinSerialize（）获取每个块下载时的字节，但不包括事务。我怎样才能获得完整的原始块？

Answer 1

我找到了一个临时解决方案：

BlockStore blockStore = new MyCustomBlockStore(NETWORK_PARAMETERS); 
blockStore.getChainHead(); 

blockChain = new BlockChain(NETWORK_PARAMETERS, blockStore); 

PeerGroup peerGroup = new PeerGroup(NETWORK_PARAMETERS, blockChain); 
peerGroup.setDownloadTxDependencies(1000); 
peerGroup.setBloomFilteringEnabled(false); 
peerGroup.addPeerDiscovery(new PeerDiscovery() { 
    private final PeerDiscovery normalPeerDiscovery = new DnsDiscovery(NETWORK_PARAMETERS); 

    @Override 
    public InetSocketAddress[] getPeers(long services, long timeoutValue, TimeUnit timeoutUnit) throws PeerDiscoveryException { 
     final List<InetSocketAddress> peers = new LinkedList<InetSocketAddress>(); 
      peers.addAll(Arrays.asList(normalPeerDiscovery.getPeers(services, timeoutValue, timeoutUnit))); 
      InetSocketAddress[] isas = new InetSocketAddress[0]; 
      return peers.toArray(isas); 
     } 

    @Override 
    public void shutdown() { 
     normalPeerDiscovery.shutdown(); 
    } 
}); 

peerGroup.startAsync(); 
peerGroup.startBlockChainDownload(new PeerDataEventListener() { 
    public void onBlocksDownloaded(Peer peer, Block block, @Nullable FilteredBlock filteredBlock, int i) { 

     List<Transaction> transactionsList = block.getTransactions(); 
     int transactions = transactionsList == null ? 0 : transactionsList.size(); 

     long height = peer.getBestHeight() - i; 
     //If the block contains transactions, it is likely to be complete. 
     Log.e(TAG, "Downloaded block " + height + " with " + transactions + " transactions"); 
     blockUpdate(block); 
    } 

    private void blockUpdate(Block fBlock) throws IOException { 
     //TODO: Update blockchain database with the full block. 
    } 

    public void onChainDownloadStarted(Peer peer, int i) { 
     Log.i(TAG, "Started to download chain on peer " + peer); 
    } 

    @Nullable 
    public List<Message> getData(Peer peer, GetDataMessage getDataMessage) { 
     //Log.i(TAG, "getData from " + peer); 
     return null; 
    } 

    public Message onPreMessageReceived(Peer peer, Message message) { 
     //Log.i(TAG, "onPreMessageReceived (" + message.getClass().getSimpleName() + ") from " + peer); 
     return message; 
    } 
}); 

就我而言，我创建了一个BlockStore存储在数据库SQLite3的块。当我得到完整的块时，我用完整的信息（交易，原始块等...）覆盖块寄存器...
