在React中，我如何处理从服务器返回的错误？

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

const MyComponent = () => {
  const [error, setError] = useState(null);

  useEffect(() => {
    const fetchData = async () => {
      try {
        const response = await fetch('https://api.example.com/data');
        if (!response.ok) {
          throw new Error('Request failed');
        }
        const data = await response.json();
        // 处理返回的数据
      } catch (error) {
        setError(error.message);
      }
    };

    fetchData();
  }, []);

  return (
    <div>
      {error && <p>{error}</p>}
      {/* 其他组件内容 */}
    </div>
  );
};

export default MyComponent;
