如何从 Truffle 控制台与 OpenZeppelin 代理合约进行交互？
How to interact with OpenZeppelin proxy contracts from Truffle console?
我不知道如何使用 @truffle/contract 与包 @openzeppelin/truffle-upgrades[=25= 部署的合约进行交互]（ProxyAdmin 和 AdminUpgradeabilityProxy）。我已经将我的合约部署到 Ganache：
Deploying 'MetaToken'

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)
网络相同 (Ganache)。
我做错了什么？
truffle-contract 中的 deployed() 方法将查找存储在合约工件中的部署地址（即您代码中的 DeployJson）。仅当您通过迁移部署合同时才会设置此值，最重要的是，它是在 实施合同的工件 上设置的。在这种情况下，它将是 MetaToken.
要与部署的实例交互，您需要执行以下操作：
const MetaToken = artifacts.require('MetaToken');
const instance = await MetaToken.deployed();
或者，绕过 deployed() 机制并直接附加：
const MetaToken = artifacts.require('MetaToken');
const instance = await MetaToken.at('0x2FCe57853cB98fCd6491ddebc8430E970CA333b5');
这将 return 代理地址 (0x2FCe57853cB98fCd6491ddebc8430E970CA333b5) 的一个 truffle-contract 实例与 MetaToken ABI，这可能是您想要的。
如果您想与 Proxy 交互以升级它或更改所有者，您应该通过 upgrades plugin methods。
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 包复制到松露项目中。
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()
