react hook 实现请求列表数据

逻辑代码，如下：

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

function App() {
  const [data, setData] = useState({ hits: [] });
  useEffect(() => {
    axios('https://hn.algolia.com/api/v1/search?query=redux')
      .then(result => {
        setData(result.data);
      })
  },[]);

  return (
    <ul>
      {data.hits.map(item => (
        <li key={item.objectID}>
          <a href={item.url}>{item.title}</a>
        </li>
      ))}
    </ul>
  );
}

export default App;

.
