web3.eth.sendSignedTransaction() 始终返回"Returned error: nonce too low"

Question

我在node中使用了[e-mail]与私有区块链进行交互。我根据 web3@1.00 的官方文件编写代码。

var Web3 = require('web3');
var Tx = require('ethereumjs-tx');


var web3 = new Web3('http://localhost:8101');


//get the privatekey
var decryptPK = web3.eth.accounts.decrypt({"address":"68c5cb5aa9f568ae2a6ec530e982f4f1144f2d10",
"crypto":{"cipher":"aes-128-ctr",
"ciphertext":"96b6a86bd5ff16a5669975974eabba844bc414bc52d9cc36843b4f41e89d46b9",
"cipherparams":{"iv":"6858473ac21c43e94add7e0b70306da5"},
"kdf":"scrypt","kdfparams":{"dklen":32,"n":262144,"p":1,"r":8,
"salt":"4dee1ee7cf929cd38938aaf0a6c83ceeb743348980052b6fb94ab139ae7e09db"}
,"mac":"f7d9bbd81f9c91ffa21e564e613bae57bd77c1914a6690f6018623ff2ce80845"},
"id":"0eb12580-d11a-49f5-91bb-3592a530e4d8","version":3}
, '123');
var privateKey = new Buffer(decryptPK.privateKey.substring(2),'hex');


//check the nonce
web3.eth.getTransactionCount('0x68c5cb5aa9f568ae2a6ec530e982f4f1144f2d10').then(console.log);

var rawTx = web3.eth.accounts.signTransaction({
from: '0x68c5cb5aa9f568ae2a6ec530e982f4f1144f2d10',
to: '0x7fdec66a5c1b69824dfe3bc29138fac9ddf13ed4',
value: '1000000000',
gas: 2000000
}, decryptPK.privateKey)
.then(console.log).rawTransaction;


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

var serializedTx = tx.serialize();

web3.eth.sendSignedTransaction('0x' + serializedTx.toString('hex'));

但是，我总是无法发送交易。web3.eth.sendSignedTransaction() 总是返回错误 "nonce too low"。

(node:78916) UnhandledPromiseRejectionWarning: Unhandled promise rejection (rejection id: 1): Error: Returned error: nonce too low
(node:78916) [DEP0018] DeprecationWarning: Unhandled promise rejections are deprecated. In the future, promise rejections that are not handled will terminate the Node.js process with a non-zero exit code.

请帮助我知道如何解决此问题。

这段代码看起来是错误的：

var rawTx = web3.eth.accounts.signTransaction({
from: '0x68c5cb5aa9f568ae2a6ec530e982f4f1144f2d10',
to: '0x7fdec66a5c1b69824dfe3bc29138fac9ddf13ed4',
value: '1000000000',
gas: 2000000
}, decryptPK.privateKey)
.then(console.log).rawTransaction;

我想在这之后rawTxundefined？您正在尝试访问Promise对象上名为"rawTransaction"的字段。

代码可能看起来像这样(完全未经测试)：

web3.eth.accounts.signTransaction({
nonce: 1,  // Use the right nonce here, just hardcoding at 1 for the example.
from: '0x68c5cb5aa9f568ae2a6ec530e982f4f1144f2d10',
to: '0x7fdec66a5c1b69824dfe3bc29138fac9ddf13ed4',
value: '1000000000',
gas: 2000000
}, decryptPK.privateKey)
.then(tx => {
var rawTx = tx.rawTransaction;
web3.eth.sendSignedTransaction(rawTx).on('receipt', console.log);
});

事务对象必须使用私钥事务发送方进行签名。 如果它显示的nonce太低，则意味着私钥不属于交易的发送者。
