如何在使用信托执行脚本时充当另一个钱包？

Question

我正在编写一个种子，以便在部署智能契约之后添加数据。我正在使用ropsten网络，在truffle-config中这样设置：

ropsten: {
      provider: function () {
        return new HDWalletProvider(MNEMONIC, INFURA_KEY)
      },
      network_id: 3,
      gas: 8000000      //make sure this gas allocation isn't over 8M, which is the max
    }

部署之后，我想用truffle exec scriptName.js调用我的脚本。在我的脚本中，我基本上需要做两件事: 1)添加一个品牌(这可以节省另一个钱包的地址)，2)调用另一个函数，作为我上面添加的品牌。此功能只能由品牌地址调用。

我可以添加品牌，但是我不能调用第二个功能，因为它仍然是由智能合同所有者调用，而不是由品牌调用。

这是我的代码：

const contract = artifacts.require('contract');
const brandAddress = '0x73aCAEf54005FE8499Ff1159A244617C123F1a53'

module.exports = function (done) {
    console.log("Getting deployed version of the contract...")

    contract.deployed().then(async (instance) => {
         console.log('Adding first Brand...')
         await instance.addBrandAddress(brandAddress);
         console.log('Brand address added: '+ brandAddress)

        //from now on act as the brand
        console.log('Creating first Token...')
        let tokenOne = [
            '1576827018',
            true,
            '43.782988;11.282723',
            '',
            'B2529234802149001329150000E20030',
            '',
            '',
            'Test data'
        ]
        await instance.createToken(tokenOne, {from: brandAddress})
        console.log('First token created: ', tokenOne)
    }).then(() => {
        console.log('Seed finished.')
        done();
    }).catch((err) => {
        console.log(err)
        done();
    })
}

这是我得到的错误：

我没有使用from: brandAddress，而是尝试使用地址的私钥(所以是from: brandAddressPK)，但那个密钥仍然没有工作。

也许我可以通过使用web3.js来做到这一点，但我需要发送一个元组作为参数，而关于web3.js，我记得的最后一件事是，这是不可能的(所以我切换到了ethers.js)。

编辑:我解决这个问题的方法是创建一个js脚本(不使用块菌)。通过使用ethers.js，我首先使用所有者的私钥创建了一个提供者，然后当我需要充当一个品牌时，我创建了一个新的提供者，并使用该品牌的私钥。

这不是我想要的，但效果很好，做好了这份工作。

可以使用自定义HDWallet提供程序解决问题。

HDWallet提供程序接受一组私钥，而不是助记符。

const contract = artifacts.require('contract');
const HDWalletProvider = require('@truffle/hdwallet-provider');

const OWNER_ADDR = '0x1234...';  // Ethereum address
const OWNER_PKEY = 'ABCD...';    // Private key (without 0x at the beginning)
const BRAND_ADDR = '0x4433...';  // Ethereum address
const BRAND_PKEY = 'B1C1...';    // Private key

module.exports = async function (done) {
  const provider = new HDWalletProvider([
      OWNER_PKEY,
      BRAND_PKEY,
    ],
    'http://localhost:8545',
    0,  // start at position 0
    2,  // and use 2 private keys
  );

  contract.setProvider(provider);

  const instance = await contract.deployed();

  // To call a method as owner
  await instance.onwerOnlyMethod({ from: OWNER_ADDR });

  // To call a method as brand
  await instance.brandOnlyMethod({ from: BRAND_ADDR });

  done();
};
