在 Truffle 中使用构造函数部署智能合约

Question

我想部署包含构造函数（2 个帐户地址和一个值 P）的合同，在 Remix 中，我手动输入了帐户和 P 值的地址，但在松露中，我手动编辑了 2_deploy_contracts.js 文件，如下所示：

合同：

constructor(address payable _account1, address payable _account2, uint _P) public {account1 = _account1;account2 = _account2; P = _P;}

2_deploy_contracts.js：

var contract = artifacts.require("contract");
module.exports = function(deployer)  {
deployer.deploy(contract, account1, account2, P);};

提前感谢您的帮助。

Answer 1

您必须声明并初始化这些参数：
var account1='0x...';
var account2='0x...';
var P=...;
deployer.deploy(contract, account1, account2, P);

Answer 2

所以我面临着类似的问题。 并且有几件事情需要注意。

1. 在你的合约中，你应该声明合约，构造函数是这样的： Coin和Reward是我的合约。

constructor(Coin _coinContractsAddress, Reward _rewardContractAddress){
    coin_ = _coinContractsAddress;
    reward_ = _rewardContractAddress;
}

2. 现在这是为了合同。 部署文件的更改应该是这样的：

部署合同.js

module.exports = async function() {
    await deployer.deploy(Coin);
    const coin_ = await Coin.deployed();

    await deployer.deploy(Reward);
    const reward_ = await Reward.deployed();
    //Now we are going to deploy these contracts, address in the 3rd Contract address named Bank.
    await deployer.deploy(Bank, coin_.address, reward_.address);
    //Point to note is we are deploying the Bank contract and in its constructor at same time we are passing the coin_.address which is the deployed contract address and reward_.address.
}

3. 现在运行 truffle 迁移，它将成功部署。 truffle migrate --reset
