truffle部署到测试网rinkeby

 部署到测试网

以上仅仅展示了一个智能合约最简单的步骤。如果需要实现更多的功能&＃xff0c;就需要在测试链上进行测试了。链上测试的重点在于对于交易的格式以及交易的数据正确性等等。

目前著名的以太坊测试链主要是:

Ø  ropsten(https://ropsten.etherscan.io/)

Ø  kovan(https://kovan.etherscan.io/)

Ø  rinkeby(https://rinkeby.etherscan.io/)

他们的区别在于共识机制的不同&＃xff0c;所幸这些测试网都有区块链浏览器支持&＃xff0c;同时又有水管可以自动申请测试ether。下面以kovan为例&＃xff0c;看一下如何将智能合约部署到测试网上面。

向测试网部署智能合约&＃xff0c;需要安装另外一个组件&＃xff1a;truffle-hdwallet-provider

npm install &＃64;truffle/hdwallet-provider

在安装完成之后&＃xff0c;需要在truffle.js 配置文件中做些修改。

要通过infura创建测试网对应的provider对象。

var HDWalletProvider &＃61; require("&＃64;truffle/hdwallet-provider");
var mnemonic &＃61; "xxxxx"; //MetaMask的助记词。module.exports &＃61; {// Uncommenting the defaults below// provides for an easier quick-start with Ganache.// You can also follow this format for other networks.// See details at: https://trufflesuite.com/docs/truffle/reference/configuration// on how to specify configuration options!//networks: {development: {host: "127.0.0.1",port: 7545,network_id: "*"},rinkeby: {provider: () &＃61;> new HDWalletProvider(mnemonic, &＃96;https://rinkeby.infura.io/v3/xxxxx&＃96;),network_id: 4, // rinkeby&＃39;s idgas: 5500000, // rinkeby has a lower block limit than mainnetconfirmations: 2, // # of confs to wait between deployments. (default: 0)timeoutBlocks: 10000, // # of blocks before a deployment times out (minimum/default: 50)skipDryRun: true // Skip dry run before migrations? (default: false for public nets )}}//,//// Truffle DB is currently disabled by default; to enable it, change enabled:// false to enabled: true. The default storage location can also be// overridden by specifying the adapter settings, as shown in the commented code below.//// NOTE: It is not possible to migrate your contracts to truffle DB and you should// make a backup of your artifacts to a safe location before enabling this feature.//// After you backed up your artifacts you can utilize db by running migrate as follows:// $ truffle migrate --reset --compile-all//// db: {// enabled: false,// host: "127.0.0.1",// adapter: {// name: "sqlite",// settings: {// directory: ".db"// }// }// }
};


请注意&＃xff0c;每个测试网络为了互相区分&＃xff0c;他们的network_id 都是不同的。

部署命令修改为

truffle migrate --network rinkeby

wallet

在项目根目录的项目配置文件truffle.js中&＃xff0c;可以使用种子&＃xff0c;在主网或测试网部署合约。下面提供一种部署到测试网rinkeby的配置

const HDWalletProvider &＃61; require(&＃39;truffle-hdwallet-provider&＃39;);
const fs &＃61; require(&＃39;fs&＃39;);
// 读取种子&＃xff0c;12个单词组成的种子
const mnemonic &＃61; fs.readFileSync("./path/to/mnemonic.secret").toString().trim();module.exports &＃61;{networks:{rinkebyTest:{provider: () &＃61;> new HDWalletProvider(mnemonic, &＃96;https://rinkeby.infura.io/v3/aa86f***60803c&＃96;,// your infura API key0, // 地址的起始索引10 // 生成的地址数量),network_id: 4,// gas: 6500000,confirmations: 2,gasPrice: 5000000000, // 5 GweiskipDryRun: true // 跳过预执行&＃xff0c;直接部署}}
}
