ethereum - 如何从 Truffle 控制台与 OpenZeppelin 代理合约进行交互？

Question

我不知道如何使用 @truffle/contract 与包 @openzeppelin/truffle-upgrades(ProxyAdmin 和 AdminUpgradeabilityProxy)部署的契约(Contract)进行交互。我已将我的合约部署到 Ganache:

   Deploying 'ProxyAdmin'

   Deploying 'AdminUpgradeabilityProxy'

这是我试过的代码:

Web3 = require("web3")
var provider = new Web3.providers.HttpProvider("http://localhost:7545");
var contract = require("@truffle/contract");
var fs=require("fs");

var DeployJson=fs.readFileSync("/path/metatoken/node_modules/@openzeppelin/upgrades-core/artifacts/AdminUpgradeabilityProxy.json");
var DeployJs=JSON.parse(DeployJson);

var AdminUpgradeabilityProxy=contract({abi: DeployJs.abi, unlinked_binary: DeployJs.bytecode, address: "0x2FCe57853cB98fCd6491ddebc8430E970CA333b5"});

AdminUpgradeabilityProxy.setProvider(provider);

let i = await AdminUpgradeabilityProxy.deployed()

但是它抛出一个错误:

Error: Contract has not been deployed to detected network (network/artifact mismatch)
    at processTicksAndRejections (internal/process/task_queues.js:93:5)
    at Function.deployed (/path/metatoken/node_modules/@truffle/contract/lib/contract/constructorMethods.js:84:11)
    at Object.checkNetworkArtifactMatch (/path/metatoken/node_modules/@truffle/contract/lib/utils/index.js:249:13)

网络是一样的(Ganache)。

我做错了什么？

Answer 1

来自 OpenZeppelin 的 Andrew B Coathup 帮助实现了这一目标。诀窍是将 ProxyAdmin 和 AdminUpgradeabilityProxy 的构建工件从 npm 包复制到 truffle 项目中。

cp node_modules/@openzeppelin/upgrades-core/artifacts/* build/contracts

然后 truffle 控制台将能够加载它们，因此您可以像往常一样与它们交互:

let proxyAdmin = await ProxyAdmin.at("0x254dffcd3277C0b1660F6d42EFbB754edaBAbC2B")
proxyAdmin.owner()
