truffle部署指定的合約-有解無憂

? ? 在truffle中部署指定的合約，可以根據檔案的Index來區別，比如，/migrations目錄下，有如下三個檔案:
? ? 1_inital_migrations.js
? ? 2_deploy_HWT.js
? ? 3_deploy_SZT.js

? ? 部署第2個合約:2_deploy_HWT.js，使用命令：

migrate -f 2 --to 2

? ? 同理，部署第3個合約:2_deploy_SZT.js，使用命令：

migrate -f 3 --to 3

? ? 類推，部署第n個合約: n_deploy_XXX.js，使用命令：

migrate -f n --to n

1 進入指定的網段

1.1 公共配置

? ? 開啟truffle-config.js里的助記詞、私鑰等配置，

const fs = require('fs');

const HDWalletProvider = require('@truffle/hdwallet-provider');
const infuraKey = fs.readFileSync(".infuraKey").toString().trim();
const mnemonic = fs.readFileSync(".mnemonic").toString().trim();

1.2 ropsten網段配置

? ? 在truffle-config.js的networks欄位里，開啟ropsten網段配置

    ropsten: {
      provider: () => new HDWalletProvider(mnemonic, `https://ropsten.infura.io/v3/` + infuraKey),
      network_id: 3,       // Ropsten's id
      gas: 5500000,        // Ropsten has a lower block limit than mainnet
      confirmations: 2,    // # of confs to wait between deployments. (default: 0)
      timeoutBlocks: 20000,  // # of blocks before a deployment times out  (minimum/default: 50)
      skipDryRun: true,     // Skip dry run before migrations? (default: false for public nets )
      port: 8545
    },

1.3 rinkeby網段配置

? ? 在truffle-config.js的networks欄位里，開啟rinkeby網段配置

    rinkeby: {
      provider: () => new HDWalletProvider(mnemonic, `https://rinkeby.infura.io/v3/` + infuraKey),
      network_id: 4,
    },

1.4 kovan網段配置

? ? 在truffle-config.js的networks欄位里，開啟kovan網段配置

    kovan: {
      provider: () => new HDWalletProvider(mnemonic, `https://kovan.infura.io/v3/` + infuraKey),
      network_id: 42,
    },

1.5 主網配置

? ? 在truffle-config.js的networks欄位里，開啟主網配置

    mainnet: {
      provider: () => new HDWalletProvider(mnemonic, `https://mainnet.infura.io/v3/` + infuraKey),
      network_id: 1,
    },

1.6 ganache配置

? ? 在truffle-config.js的networks欄位里，添加一個ganache網段，用于本地測驗

    ganache: {
      host: "127.0.0.1",     // Localhost (default: none)
      port: 8545,            // Standard Ethereum port (default: none)
      network_id: "*",       // Any network (default: none)
    },

? ? truffle-config.js的完整配置如下：
? ? //truffle-config.js

const fs = require('fs');

const HDWalletProvider = require('@truffle/hdwallet-provider');
const infuraKey = fs.readFileSync(".infuraKey").toString().trim();
const mnemonic = fs.readFileSync(".mnemonic").toString().trim();
