使用web3.js将新合同部署到以太网络

npm install web3

const Web3 = require('web3');
const web3 = new Web3('http://localhost:8545');

const contractABI = [...]; // 合约的ABI
const contractBytecode = '0x...'; // 合约的字节码
const contract = new web3.eth.Contract(contractABI);

const deployOptions = {
  data: contractBytecode,
  arguments: [arg1, arg2, ...], // 合约构造函数参数
};
const deployTransaction = contract.deploy(deployOptions);
const deployReceipt = await deployTransaction.send({
  from: accountAddress,
  gas: gasLimit,
});
const contractAddress = deployReceipt.contractAddress;

const myContract = new web3.eth.Contract(contractABI, contractAddress);
const result = await myContract.methods.myMethod(arg1, arg2).call();
