如何在更新请求后触发useEffect重新渲染

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

function MyComponent() {
  const [data, setData] = useState(null);
  const [updateRequest, setUpdateRequest] = useState(0);

  useEffect(() => {
    // 发送更新请求的逻辑
    fetchData();

    // 清除副作用的函数
    return () => {
      // 可选的清除逻辑
    };
  }, [updateRequest]);

  const fetchData = async () => {
    try {
      // 发送更新请求的代码
      const response = await fetch('https://api.example.com/update');
      const newData = await response.json();
      setData(newData);
    } catch (error) {
      // 处理错误的逻辑
    }
  };

  const handleUpdate = () => {
    setUpdateRequest(prevRequest => prevRequest + 1);
  };

  return (
    <div>
      <button onClick={handleUpdate}>更新数据</button>
      {data && <p>{data}</p>}
    </div>
  );
}

export default MyComponent;
