web3 gives " Error: Returned error: invalid sender" when broadcasting transaction

Question

我是 web3 和以太坊区块链的新手。我尝试使用以下代码广播交易，但它总是给我一个无效的发件人 error.The 示例代码如下所示。

const Tx = require('ethereumjs-tx').Transaction;

const Web3 = require('web3');
var url = 'https://ropsten.infura.io/v3/XXX';
const web3 = new Web3(new Web3.providers.HttpProvider(url));


const account1 = '0xaB7BXXX';
web3.eth.defaultAccount =  account1;



const privatekey1 = Buffer.from('fee069363aXXX','hex');


web3.eth.getTransactionCount(account1, (err, txCount) => {

        data = "0xXXX";
        const txObject = {
            nonce:    web3.utils.toHex(txCount),
            gasLimit: web3.utils.toHex(200000), 
            gasPrice: web3.utils.toHex(web3.utils.toWei('10', 'gwei')),
            data: data
                 }
        const tx = new Tx(txObject)
        tx.sign(privatekey1)

        const serializedTx = tx.serialize()
        const raw = '0x' + serializedTx.toString('hex')


        web3.eth.sendSignedTransaction(raw, (err, txHash) => {
            console.log('err:', err, 'txHash:', txHash)
        })
    });

错误发生在下面一行

web3.eth.sendSignedTransaction(raw, (err, txHash) => {
            console.log('err:', err, 'txHash:', txHash)
        })
    });

ERROR:

请帮助我知道如何解决这个问题。谢谢

你可以尝试改变 const tx = new Tx(txObject); 到 const tx = new Tx(txObject, { chain: 'ropsten' });
