转账前：

转账后：

async function interact() {
  const web3 = new Web3(
    new Web3.providers.HttpProvider('http://127.0.0.1:7545')
  )
  web3.eth.Contract.handleRevert = true
  const accounts = await web3.eth.getAccounts()

  console.log(accounts)

  let balance1, balance2

  balance1 = await web3.eth.getBalance(accounts[0])

  balance2 = await web3.eth.getBalance(accounts[1])

  console.log(balance1, web3.utils.fromWei(balance1, 'ether'))
  console.log(balance2, web3.utils.fromWei(balance2, 'ether'))

  const transaction = {
    from: accounts[0],

    to: accounts[1],

    value: web3.utils.toWei('1', 'ether'),
  }

  const transactionHash = await web3.eth.sendTransaction(transaction)

  console.log('transactionHash', transactionHash)

  balance1 = await web3.eth.getBalance(accounts[0])

  balance2 = await web3.eth.getBalance(accounts[1])

  console.log(balance1, web3.utils.fromWei(balance1, 'ether'))
  console.log(balance2, web3.utils.fromWei(balance2, 'ether'))

  // const gasPrice = await web3.eth.getGasPrice()

  // console.log('gasUsed', transactionHash.gasUsed)
  // console.log('价格', web3.utils.fromWei(gasPrice, 'ether'))
  let total =  transactionHash.effectiveGasPrice * transactionHash.gasUsed + balance1 + balance2
  console.log('total', total)

  const block = await web3.eth.getBlockNumber()

  console.log('Last block:', block)
