我跟着松露的仲裁教程:https ://truffleframework.com/tutorials/building-dapps-for-quorum-private-enterprise-blockchains
现在我想将 SimpleStorage.sol 智能合约迁移到区块链,但我想让它添加“PrivateFor”参数。
这是我的智能合约:
pragma solidity ^0.4.17;
contract SimpleStorage {
uint public storedData;
constructor(uint initVal) public {
storedData = initVal;
}
function set(uint x) public {
storedData = x;
}
function get() view public returns (uint retVal) {
return storedData;
}
}
这是我的:2_deploy_simplestorage.js
var SimpleStorage = artifacts.require("SimpleStorage");
module.exports = function(deployer) {
deployer.deploy(SimpleStorage, 42, {privateFor: ["ROAZBWtSacxXQrOe3FGAqJDyJjFePR5ce4TSIzmJ0Bc="]})
};
但是当我做松露迁移时,我得到了这个错误:
$ truffle migrate
⚠️ Important ⚠️
If you're using an HDWalletProvider, it must be Web3 1.0 enabled or your migration will hang.

当我不添加“privateFor”参数时,它可以工作:
var SimpleStorage = artifacts.require("SimpleStorage");
module.exports = function(deployer) {
deployer.deploy(SimpleStorage, 42)
};
但我需要这个 privateFor 参数..
有人知道如何解决这个问题吗?
