如何使用json在Listview中添加头部

{
  "header": {
    "title": "ListView Header",
    "subtitle": "This is the header of the ListView"
  }
}

var headerData = {
  "header": {
    "title": "ListView Header",
    "subtitle": "This is the header of the ListView"
  }
};

var headerString = JSON.stringify(headerData);

import React from 'react';

class ListView extends React.Component {
  render() {
    // 将头部数据作为props传递给ListView组件
    const headerData = JSON.parse(this.props.headerString);

    return (
      <div>
        <div>
          <h1>{headerData.header.title}</h1>
          <p>{headerData.header.subtitle}</p>
        </div>
        {/* 其他ListView内容 */}
      </div>
    );
  }
}

export default ListView;

const express = require('express');
const app = express();

app.get('/listview', (req, res) => {
  const headerData = {
    "header": {
      "title": "ListView Header",
      "subtitle": "This is the header of the ListView"
    }
  };

  const headerString = JSON.stringify(headerData);

  res.send(headerString);
});

app.listen(3000, () => {
  console.log('Server is running on port 3000');
});
