错误:现在太低

Question

我试图将eth从一个地址发送到另一个地址，但我得到了一个错误：Error: Returned error: nonce too low，可能是什么问题？

const Web3 = require('web3')


const web3 = new Web3(new Web3.providers.HttpProvider('https://mainnet.infura.io'))   
var Tx = require('ethereumjs-tx').Transaction;
var privateKey = Buffer.from('private_key', 'hex');

var rawTx = {
  nonce: '0x000',
  gasPrice: '0x09184e72a000',
  gasLimit: '0x2710',
  to: 'to_address',
  value: '0x00',
}

var tx = new Tx(rawTx);
tx.sign(privateKey);

var serializedTx = tx.serialize();

web3.eth.sendSignedTransaction('0x' + serializedTx.toString('hex'))
.on('receipt', console.log);

Answer 1

Error: Returned error: nonce too low

nonce基本上是指从特定帐户地址执行的事务数。为了修复上面的错误：

const accountNonce =
  '0x' + (web3.eth.getTransactionCount(ethereum_account_address) + 1).toString(16)

将rawTx中的nonce值替换为上面的值。

var rawTx = {
  nonce: accountNonce,
  gasPrice: '0x09184e72a000',
  gasLimit: '0x2710',
  to: 'to_address',
  value: '0x00',
}

这将消除现在太低的错误。
