如何使用Web3发送以太网，并从另一个地址支付燃气费？

npm install web3

const Web3 = require('web3');
const web3 = new Web3('https://mainnet.infura.io/v3/your-infura-project-id');

const account = web3.eth.accounts.create();
console.log('New account address:', account.address);
console.log('New account private key:', account.privateKey);

const address = 'your-account-address';
const privateKey = 'your-account-private-key';
web3.eth.accounts.wallet.add({
  address: address,
  privateKey: privateKey
});
web3.eth.defaultAccount = address;

const toAddress = 'recipient-address';
const amount = web3.utils.toWei('1', 'ether');
web3.eth.sendTransaction({
  from: address,
  to: toAddress,
  value: amount
})
.then((receipt) => {
  console.log('Transaction receipt:', receipt);
})
.catch((error) => {
  console.error('Transaction error:', error);
});

web3.eth.estimateGas({
  from: address,
  to: toAddress,
  value: amount
})
.then((gasLimit) => {
  const gasPrice = web3.utils.toWei('10', 'gwei');
  const gasCost = gasLimit * gasPrice;
  web3.eth.sendTransaction({
    from: address,
    to: toAddress,
    value: amount,
    gas: gasLimit,
    gasPrice: gasPrice
  })
  .then((receipt) => {
    console.log('Transaction receipt:', receipt);
    console.log('Gas cost:', web3.utils.fromWei(gasCost, 'ether'), 'ETH');
  })
  .catch((error) => {
    console.error('Transaction error:', error);
  });
})
.catch((error) => {
  console.error('Gas estimation error:', error);
});
