我的代码如下，用于生成原始交易的简单脚本。

var path = require('path').dirname(require.main.filename)
var bitcore = require('bitcore-lib')
var fs = require('fs')
var UnspentOutput = bitcore.Transaction.UnspentOutput
const blockchain = require('blockchain.info')

var json = fs.readFileSync(path + '/' + '1MPP77eCzAsCKMjtWzdcNw4XMUxb5ePBeA.json');
obj = JSON.parse(json)

var address = "1C3xRrMetAdz2VSnbuDTnwHj3Dyeo9auk2"
var amount = 1000000 //satoshis
var privkeySet = bitcore.PrivateKey.fromWIF(obj["priv"]);
var cAddr = "1MPP77eCzAsCKMjtWzdcNw4XMUxb5ePBeA"

blockchain.blockexplorer.getUnspentOutputs(cAddr).then(outputs => {
  var utxo = new UnspentOutput({
    "txid" : outputs['unspent_outputs'][0]['tx_hash'],
    "vout" : outputs['unspent_outputs'][0]['tx_output_n'],
    "address" : cAddr,
    "script" : outputs['unspent_outputs'][0]['script'],
    "satoshis" : outputs['unspent_outputs'][0]['value']
  })

  var utxos = [utxo]

  var tx = new bitcore.Transaction()
    .from(utxos)
    .to(address, amount)
    .change(cAddr)
    .fee(10000)
    .sign(privkeySet);

  console.log("transaction = " + tx.verify());
  console.log("Signature = " + tx.isFullySigned());

  console.log(tx)
});

但是，当我通过 blockchain.info 广播原始交易时，我得到以下信息......

Missing parents for 62ce2eacfb96368dc7751e023d0890eae2e700c46dce1bd91192be27db6e97e7 while inserting: [872f22da56a21f500b87db1a6361ca228cca6b75913faeb4cb9ce2d19133a185]

两者都verify返回isFullySignedtrue。原始交易如下...

完全不知道出了什么问题。交易正在签名，未使用的输出很好，等等。感谢任何帮助，谢谢！
