21.3. 配置 Truffle

安装 truffle-hdwallet-provider

			
$ npm install truffle-hdwallet-provider			
			
		

修改 truffle.js 文件

			
var HDWalletProvider = require("truffle-hdwallet-provider"); 

// infura 为你提供的 apikey 请与你申请到的 key 保持一致
var infura_apikey = "CsS9shwaAab0z7B4LP2d";
 
// 你以太坊钱包地址 进入 MetaMask -> Settings -> reveal seed words 复制到此处
var mnemonic = "drill hunt food team moment mistake bird attitude tunnel ecology sister resist"; 

module.exports = {
  networks: {
    development: {
      host: "127.0.0.1",
      port: 7545,
      network_id: "*"
    },
    private: {
      host: "localhost",
      port: 8545,
      network_id: "*" // Match any network id
    },
    ropsten: {
      provider: new HDWalletProvider(mnemonic, "https://ropsten.infura.io/"+infura_apikey),
      network_id: 3,
      gas: 3012388,
      gasPrice: 30000000000
    },
    main: {
      provider: new HDWalletProvider(mnemonic, "https://mainnet.infura.io/"+infura_apikey),
      network_id: 3,
      gas: 3012388,
      gasPrice: 1000000000
    }
  }
};
