有没有在React类组件中使用Modal的方法

import React, { useState } from 'react';
import Modal from 'react-modal';

const MyComponent = () => {
  const [modalIsOpen, setModalIsOpen] = useState(false);

  const openModal = () => {
    setModalIsOpen(true);
  };

  const closeModal = () => {
    setModalIsOpen(false);
  };

  return (
    <div>
      <button onClick={openModal}>打开Modal</button>
      <Modal isOpen={modalIsOpen} onRequestClose={closeModal}>
        <h2>Modal标题</h2>
        <p>Modal内容</p>
        <button onClick={closeModal}>关闭Modal</button>
      </Modal>
    </div>
  );
};

export default MyComponent;
