solidity0.7.1以上本地编译部署配置_solity constructor 如何部署-优快云博客

由于truffle的solc list 最高只有0.7.1，笔者使用的是0.8.0，因此有了本文

一、solc

1.安装solcjs

        npm install solc

2.官方文档

GitHub - ethereum/solc-js: Javascript bindings for the Solidity compiler

3. Compile.js 用于编译合约，生成bytecode和abi

const fs = require("fs"),
    solc = require('solc');
const contractData=fs.readFileSync('Loan.sol').toString() //读入合约文件
var input = {
    language: 'Solidity',
    sources: {
        'test.sol': {  //此处可随意更改，下面跟此处保持一致即可
            content: contractData
        }
    },
    settings: {
        outputSelection: {
            '*': {
                '*': ['*']
            }
        }
    }
};

var output = JSON.parse(solc.compile(JSON.stringify(input)));
// `output` here contains the JSON output as specified in the documentation
for (var contractName in output.contracts['test.sol']) {
    fs.writeFileSync('./build/'+contractName+'_abi.js',JSON.stringify(output.contracts['test.sol'][contractName].abi))
    fs.writeFileSync('./build/'+contractName+'_bytecode.js',output.contracts['test.sol'][contractName].evm.bytecode.object)
}

4.Migration.js 用于合约部署


const fs = require("fs");
const {ethers} = require("ethers");


const LoanABI=JSON.parse(fs.readFileSync("./build/Loan_abi.js").toString())
const LoanByteCode=fs.readFileSync("./build/Loan_bytecode.js").toString()


// 合约拥有者的帐号
let url = 'http://localhost:8545'; //此处填写jrpc地址和端口
let customHttpProvider = new ethers.providers.JsonRpcProvider(url);
const privateKey = ""; //部署合约的钱包地址的私钥，metamask中选项->账户详情->导出私钥

let walletWithProvider = new ethers.Wallet(privateKey, customHttpProvider);
(async function() {

    // 常见合约工厂实例
    let factory = new ethers.ContractFactory(LoanABI, LoanByteCode, walletWithProvider);

    // 请注意，我们将 "Hello World" 作为参数传递给合约构造函数constructor
    let contract = await factory.deploy();

    // 部署交易有一旦挖出，合约地址就可用
    // 参考: https://ropsten.etherscan.io/address/0x2bd9aaa2953f988153c8629926d22a6a5f69b14e
    fs.writeFileSync('./build/contractAddress.js',contract.address)
    console.log(contract.address);
    // "0x2bD9aAa2953F988153c8629926D22A6a5F69b14E"

    // 发送到网络用来部署合约的交易
    // 查看: https://ropsten.etherscan.io/tx/0x159b76843662a15bd67e482dcfbee55e8e44efad26c5a614245e12a00d4b1a51
    console.log(contract.deployTransaction.hash);
    // "0x159b76843662a15bd67e482dcfbee55e8e44efad26c5a614245e12a00d4b1a51"

    //合约还没有部署;我们必须等到它被挖出
    await contract.deployed()

    // 好了 合约已部署。
})();
