useEffect中异步函数的React Hook警告:useEffect函数必须返回清理函数或不返回任何值

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

const MyComponent = () => {
  const fetchData = useCallback(async () => {
    try {
      const response = await fetch('https://api.example.com/data');
      const data = await response.json();
      // 处理数据
    } catch (error) {
      // 处理错误
    }
  }, []);

  useEffect(() => {
    fetchData();

    // 返回清理函数
    return () => {
      // 清理操作，比如取消请求
    };
  }, [fetchData]);

  return (
    <div>
      {/* 组件内容 */}
    </div>
  );
};

export default MyComponent;
