如何在不使用外部钱包的情况下处理web3JS

Question

我想使用web3JS配置，而不使用像metamask这样的外部钱包。使用本应每周运行的cron作业来处理自动化功能。由于metamask请求使用send((方法删除我想要使用的帐户的权限，我将在那里上传私钥和其他东西。我从网上得到了这个代码，它适用于本地/浏览器钱包，不知道在哪里编辑。

import Web3 from "web3";
const getWeb3 = () =>
new Promise((resolve, reject) => {
// Wait for loading completion to avoid race conditions with web3 injection timing.
window.addEventListener("load", async () => {
// Modern dapp browsers...
if (window.ethereum) {
const web3 = new Web3(window.ethereum);
try {
// Request account access if needed
await window.ethereum.enable();
// Accounts now exposed
resolve(web3);
console.log("enabled", web3);
console.log("MetaMask injected");
} catch (error) {
reject(error);
}
}
// Legacy dapp browsers...
else if (window.web3) {
// Use Mist/MetaMask's provider.
const web3 = window.web3;
// const web3 = window.web3.currentProvider.enable();
console.log("Injected web3 detected.");
resolve(web3);
}
// Fallback to localhost; use dev console port by default...
else {
const provider = new Web3.providers.HttpProvider(
"http://127.0.0.1:7545"
);
const web3 = new Web3(provider);
console.log("No web3 instance injected, using Local web3.");
resolve(web3);
}
});
});
export default getWeb3;

const Web3 = require("web3");
const WalletProvider = require("@truffle/hdwallet-provider");

let provider = new WalletProvider({
mnemonic: {
phrase:
"*******",
},
providerOrUrl: "https://goerli.infura.io/v3/****************",
});
const web3 = new Web3(provider);
const fetch123 = async () => {
const accounts = await web3.eth.getAccounts();
console.log(accounts);
};
fetch123();
