如何从Metamask | ReactJS获取账号的公钥和私钥

import React, { useEffect, useState } from 'react';
import Web3 from 'web3';

const MyComponent = () => {
  const [publicKey, setPublicKey] = useState('');
  const [privateKey, setPrivateKey] = useState('');

  useEffect(() => {
    const connectToMetamask = async () => {
      if (window.ethereum) {
        try {
          await window.ethereum.enable();
          const web3 = new Web3(window.ethereum);
          const accounts = await web3.eth.getAccounts();
          const currentAccount = accounts[0];
          setPublicKey(currentAccount);
          // 注意：Metamask不会直接提供私钥，以下代码仅作为示例，实际应用中不应该暴露私钥
          const currentAccountPrivateKey = await web3.eth.accounts.wallet[0].privateKey;
          setPrivateKey(currentAccountPrivateKey);
        } catch (error) {
          console.error(error);
        }
      } else {
        console.error('请安装Metamask插件');
      }
    };

    connectToMetamask();
  }, []);

  return (
    <div>
      <p>公钥：{publicKey}</p>
      <p>私钥：{privateKey}</p>
    </div>
  );
};

export default MyComponent;
