首先，之前做是在本地开启一个区块链，然后把智能合约部署到本地区块链上面，然后进行操作，但是，如果要想部署到真正的互联网上，需要做一些处理，下面就开始做处理

1.下载真实环境所需要的环境HDWalletProvider

必须指定0.03版本，其他版本有坑

 npm install truffle-hdwallet-provider@0.0.3 --save

验证安装是否成功

2.然后注册MetaMask服务商

注册Infura,使用之前需要访问令牌 Infura

https://infura.io/

选择ropsten，然后复制链接:ropsten.infura.io/v3/0…

3.获取 url

#############

4.请求（修改deploy.js）

let Web3 = require('web3')
let {interface, bytecode} = require('./compile')
// web3.setProvider(new Web3.providers.HttpProvider('http://localhost:8545'))
//*************************************************************************************修改
var HDWalletProvider = require("truffle-hdwallet-provider");
var mnemonic ="ice skirt toy confirm type soup similar gloom girl kidney say demise";
var provider = new HDWalletProvider(mnemonic,"https://ropsten.infura.io/v3/02cd1e3c295c425597fa105999493baa");
//*************************************************************************************修改
let web3 = new Web3(provider)

deploy = async () => {
    try {
        //获取部署账户
        accounts = await web3.eth.getAccounts()
        contractInstance = await new web3.eth.Contract(JSON.parse(interface)).deploy(
            {
                data: bytecode
                // arguments: ['']// 构造函数如果没有参数，就一定不要传
            }
        ).send({
            from: accounts[0],
            gas: '1000000'
        })
        console.log('address :', contractInstance.options.address)
    } catch (e) {
        console.log("11111111111111111111111111111111",e)
    }
}
deploy()

5.部署

修改这三行代码，意思是把本地的巧克力区块链替换成真实测试链上，其他暂时不用动

node deploy.js

然后如果部署成功之后，会出现一个地址address,把这个地址复制到

import web3 from '../utils/getWeb3'
//通过web3，找到我们已经部署好的合约实例
//ABI
//合约的地址
const abi = [ { "constant": true, "inputs": [], "name": "getBalance", "outputs": [ { "name": "", "type": "uint256" } ], "payable": false, "stateMutability": "view", "type": "function" }, { "constant": true, "inputs": [], "name": "winner", "outputs": [ { "name": "", "type": "address" } ], "payable": false, "stateMutability": "view", "type": "function" }, { "constant": true, "inputs": [], "name": "getPlayers", "outputs": [ { "name": "", "type": "address[]" } ], "payable": false, "stateMutability": "view", "type": "function" }, { "constant": true, "inputs": [], "name": "round", "outputs": [ { "name": "", "type": "uint256" } ], "payable": false, "stateMutability": "view", "type": "function" }, { "constant": true, "inputs": [], "name": "getPlayersCount", "outputs": [ { "name": "", "type": "uint256" } ], "payable": false, "stateMutability": "view", "type": "function" }, { "constant": true, "inputs": [], "name": "manager", "outputs": [ { "name": "", "type": "address" } ], "payable": false, "stateMutability": "view", "type": "function" }, { "constant": true, "inputs": [ { "name": "", "type": "uint256" } ], "name": "players", "outputs": [ { "name": "", "type": "address" } ], "payable": false, "stateMutability": "view", "type": "function" }, { "constant": false, "inputs": [], "name": "play", "outputs": [], "payable": true, "stateMutability": "payable", "type": "function" }, { "constant": false, "inputs": [], "name": "tuijiang", "outputs": [], "payable": false, "stateMutability": "nonpayable", "type": "function" }, { "inputs": [], "payable": true, "stateMutability": "payable", "type": "constructor" }, { "constant": false, "inputs": [], "name": "kaijiang", "outputs": [], "payable": false, "stateMutability": "nonpayable", "type": "function" } ]
//************************地址写到这里面
const contractAddress = '0x143066ab1c9432FB8Cf61B48603E74e8B13ee52B'
//
let lotteryContract = new web3.eth.Contract(abi, contractAddress)
//
export default lotteryContract

5.运行测试

 node run start

6.开始gogogogo
