在react挂钩中输入api端点查询的输入数据

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

function DataFetchingComponent({ endpoint }) {
  const [data, setData] = useState(null);
  const [loading, setLoading] = useState(true);
  const [error, setError] = useState(null);

  useEffect(() => {
    let isMounted = true;

    const fetchData = async () => {
      try {
        const response = await fetch(endpoint);
        if (!response.ok) {
          throw new Error('Network response was not ok');
        }
        const result = await response.json();
        if (isMounted) {
          setData(result);
        }
      } catch (err) {
        if (isMounted) {
          setError(err);
        }
      } finally {
        if (isMounted) {
          setLoading(false);
        }
      }
    };

    fetchData();

    return () => {
      isMounted = false;
    };
  }, [endpoint]);

  if (loading) return <div>Loading...</div>;
  if (error) return <div>Error: {error.message}</div>;

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

export default DataFetchingComponent;
