web3.eth.sendSignedTransaction()始终返回“返回的错误:随机数太低”。 [英] web3.eth.sendSignedTransaction() always return "Returned error: nonce too low"
问题描述
我在node.js中使用了web3@1.00与私有区块链进行交互。而且我是根据web3@1.00的正式文件编写代码的。
I used web3@1.00 in node.js to interact with private blockchain. And I write the code according to the official documents of web3@1.00.
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,我始终无法发送交易。 web3.eth.sendSignedTransaction()始终返回错误 nonce too low。
However, I always fail to send a transaction. The web3.eth.sendSignedTransaction() always return the error "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。谢谢。
Please help me know how to fix this problem. Thanks.
推荐答案
这段代码看起来不对:
var rawTx = web3.eth.accounts.signTransaction({
from: '0x68c5cb5aa9f568ae2a6ec530e982f4f1144f2d10',
to: '0x7fdec66a5c1b69824dfe3bc29138fac9ddf13ed4',
value: '1000000000',
gas: 2000000
}, decryptPK.privateKey)
.then(console.log).rawTransaction;
我假设 rawTx
是未定义
?您正在尝试访问 Promise
对象上的一个名为 rawTransaction的字段。
I assume rawTx
is undefined
after this? You're trying to access a field called "rawTransaction" on a Promise
object.
代码应该看起来像像这样的东西(完全未经测试):
The code should probably look something like this (completely untested):
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);
});
