当从命令提示符运行web3代码时，事务哈希是“未定义的”

Question

我编写了这个java脚本代码来将测试醚发送到我的另一个帐户：

var Tx = require('ethereumjs-tx').Transaction
var Web3 = require('web3')
web3 = new Web3('https://ropsten.infura.io/hqRzEqFKv6IsjRxfVUMH')
const account1 = '0x0539B9c9C886e93778542B553C64cb5EAfB902b1'
const account2 = '0xca7F442c44b079dd07324C9c7eDfe348b92f46c9'
const privatekey1 = Buffer.from('cxxxxxxxxxxxxx5xd0804xxxxxxx238ca1aed1xxx' , 'hex')
web3.eth.getTransactionCount(account1 , (err, transCount) => {
const txObject = {
nonce: web3.utils.toHex(transCount) ,
to: account2 ,
value: web3.utils.toHex(web3.utils.toWei('1' , 'ether')) ,
gasLimit: web3.utils.toHex(30000) ,
gasPrice: web3.utils.toHex(web3.utils.toWei('10' , 'gwei'))
}
var tx = new Tx(txObject)
tx.sign(privatekey1)
const serializedTransaction = tx.serialize()
const raw = '0x' + serializedTransaction.toString('hex')
web3.eth.sendSignedTransaction(raw , (err, txHash) => 
  {console.log('txHash: ' , txHash)})
})

现在，我在命令提示符中运行以下代码：

C:\Users\HP\path>
node testEther

这一产出如下：

txHash: undefined

txHash:未定义

这一切为什么要发生？我试着连接到不同的网络，但问题仍然存在。我已经检查了我的测试以太平衡，这表明我有足够的ether.The事务根本没有发生。我和罗丝汀的联系方式错了吗？

你拥有的地方

var tx = new Tx(txObject)

你需要

const tx = new Tx(txObject, {chain:'ropsten', hardfork: 'petersburg'})

此代码在本地工作。更换你的私钥和私钥。

• web3 1.2.4
• Etalumjs-TX2.1.1(安装有单独的npm install ethereumjs-tx)

var Tx = require('ethereumjs-tx').Transaction
var Web3 = require('web3');
var web3 = new Web3('https://ropsten.infura.io/v3/INFURA_PROJECT');
const account1 = '0x926f8E72CE94491Cafba874b4affD40C3b05a5e3'
const account2 = '0xca7F442c44b079dd07324C9c7eDfe348b92f46c9'
const privatekey1 = Buffer.from('PRIVATE_KEY' , 'hex')
web3.eth.getTransactionCount(account1 , (err, transCount) => {
  const txObject = {
    nonce: web3.utils.toHex(transCount) ,
    from: account1,
    to: account2 ,
    value: web3.utils.toHex(web3.utils.toWei('.01' , 'ether')) ,
    gasLimit: web3.utils.toHex(30000) ,
    gasPrice: web3.utils.toHex(web3.utils.toWei('10' , 'gwei'))
  }
  const tx = new Tx(txObject, {chain:'ropsten', hardfork: 'petersburg'})
  tx.sign(privatekey1)
  const serializedTransaction = tx.serialize()
  const raw = '0x' + serializedTransaction.toString('hex')
  web3.eth.sendSignedTransaction(raw , (err, txHash) => {
    console.log('txHash: ' , txHash)
  });
});

由此产生的交易：
