未处理的拒绝(TypeError)：在REACT FETCH中将循环结构转换为JSON

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

function DataFetchingComponent() {
  const [data, setData] = useState(null);
  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(`HTTP error! status: ${response.status}`);
        }

        const jsonData = await response.json();
        setData(jsonData);
      } catch (error) {
        setError(error.message);
      }
    };

    fetchData();
  }, []);

  if (error) {
    return <div>Error: {error}</div>;
  }

  if (!data) {
    return <div>Loading...</div>;
  }

  return (
    <div>
      <h1>Data</h1>
      <pre>{JSON.stringify(data, null, 2)}</pre>
    </div>
  );
}

export default DataFetchingComponent;
