使用 bitcoinj/peercoinj 庫簽署具有多個輸入的交易

祝大家有美好的一天！我在向交易中添加簽名輸入時遇到了一些麻煩。目前，我正在使用 altCoin（fork peercoin）貨幣。我正在嘗試通過以下方式建構事務：

for (UTXO utxo : mUTXOs) {

       if (!done) {
           utxosValue += utxo.getValue().longValue();

           TransactionOutPoint outPoint = new TransactionOutPoint(params, utxo.getIndex(), utxo.getHash());
           byte[] privKeyBytes = HEX.decode(privKeyAsHex);
           ECKey ecKey = ECKey.fromPrivate(privKeyBytes);


           transaction.addSignedInput(outPoint, utxo.getScript(), ecKey, Transaction.SigHash.ALL, true);

           //here is adding outputs
           ....
           ....

           //serialization of the transaction and getting raw transaction
           byte[] bytesRawTransaction = transaction.peercoinSerialize();
           String rawTransaction = HEX.encode(bytesRawTransaction);

           // and here is broadcasting
           ....
           ....

           done = true;
       }
}

但是，不幸的是，伺服器響應是：

16: mandatory-script-verify-flag-failed (Script evaluated without error but finished with a false/empty top stack element)

我真的嘗試了很多形成簽名輸入的變體，但我猜它們都是不正確的。

我知道答案很接近，但我試圖在幾天內解決這個問題。

我做錯了什麼？

請幫忙！

再會！最後我找到了一個解決方案，我希望它對某人有用。

問題是我試圖在將輸出和其他資訊添加到交易之前簽署輸入。所以現在我用 method 添加輸入addInput()。在我用addSignedInput()方法做之前。在我的 TX 中添加所有輸入和輸出後，我嘗試手動簽署每個輸入：

for (int i = 0; i < transaction.getInputs().size(); i++) {
   TransactionInput transactionInput = transaction.getInput(i);
   byte[] privKeyBytes = HEX.decode(privKeyHex);
   ECKey ecKey = ECKey.fromPrivate(privKeyBytes);

   Script scriptPubKey = ScriptBuilder.createOutputScript(Address.fromBase58(params, mUTXOs.get(i).getAddress()));

   Sha256Hash hash = transaction.hashForSignature(i, scriptPubKey, Transaction.SigHash.ALL, true);
   ECKey.ECDSASignature ecSig = ecKey.sign(hash);
   TransactionSignature txSig = new TransactionSignature(ecSig, Transaction.SigHash.ALL, true);
   if (scriptPubKey.isSentToRawPubKey()) {
       transactionInput1.setScriptSig(ScriptBuilder.createInputScript(txSig));
   } else {
       if (!scriptPubKey.isSentToAddress()) {
           throw new ScriptException("Don\'t know how to sign for this kind of scriptPubKey: " + scriptPubKey);
       }
   transactionInput.setScriptSig(ScriptBuilder.createInputScript(txSig, ecKey));
   }
}

就是這樣。當然，在那之後我序列化目前的 tx 並廣播它。
