页面加载时React js调用api

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

const MyComponent = () => {
  const [data, setData] = useState([]);

  useEffect(() => {
    fetchData();
  }, []);

  const fetchData = async () => {
    try {
      const response = await fetch('api-url');
      const jsonData = await response.json();
      setData(jsonData);
    } catch (error) {
      console.error('Error fetching data:', error);
    }
  };

  return (
    <div>
      {/* 在这里使用获取到的数据进行渲染 */}
    </div>
  );
};

export default MyComponent;
