react中的分页不起作用。加载后，在URL字符串中添加额外内容

import React, { useState, useEffect } from 'react';
import { Link, useLocation } from 'react-router-dom';

const MyComponent = () => {
  const location = useLocation();
  const [data, setData] = useState([]);
  const [currentPage, setCurrentPage] = useState(1);
  const [totalPages, setTotalPages] = useState(0);

  useEffect(() => {
    // 根据当前页码获取数据
    fetchData(currentPage);
  }, [currentPage]);

  const fetchData = (page) => {
    // 从服务器获取数据并更新状态
    // ...

    // 更新总页数
    setTotalPages(10); // 假设总共有10页数据
  };

  const handlePageChange = (page) => {
    setCurrentPage(page);
  };

  return (
    <div>
      {/* 分页组件 */}
      <Pagination
        currentPage={currentPage}
        totalPages={totalPages}
        onPageChange={handlePageChange}
      />

      {/* 数据展示 */}
      {data.map((item) => (
        <div key={item.id}>{item.name}</div>
      ))}

      {/* 添加额外内容到URL字符串 */}
      <Link to={`${location.pathname}?extra=content`}>Link with extra content</Link>
    </div>
  );
};

export default MyComponent;
