如何解决使用web3的Object.exports.toBuffer中的类型无效
我尝试通过Truffle将原始交易发送给Ganache。 错误消息“ Object.exports.toBuffer处的类型无效”。
代码如下：
const Tx = require('ethereumjs-tx').Transaction;
const privateKey = Buffer.from('5b58ae3fe5bf48d05f0a94c87a28fb480ec2bc200a4423ab42ea9557f3617743','hex');
const payment_usercashTx = {
nonce: myAsyncNonceFunction(),gasPrice: web3.utils.toHex(25000),gasLimit: web3.utils.toHex(10e9),to: '0x107180312267DB452930731EA475187BdD4948DB',from: web3.eth.defaultAccount,value: '0x00',data: encode_usercash
}
let usercashTx = new Tx(payment_usercashTx);
usercashTx.sign(privateKey);
let usercash_serializedTx = usercashTx.serialize();
web3.eth.sendSignedTransaction('0x' + usercash_serializedTx.toString('hex'))
.on('receipt',console.log);
新消息：
