axios request + react函数内的钩子导致无限循环

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

const MyComponent = () => {
  useEffect(() => {
    const fetchData = async () => {
      const response = await axios.get('https://api.example.com/data');
      // 处理数据
    };

    fetchData();
  }, []);

  return (
    // 组件的 JSX
  );
};

export default MyComponent;

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

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

  useEffect(() => {
    const fetchData = async () => {
      const response = await axios.get('https://api.example.com/data');
      setData(response.data);
    };

    if (!data) {
      fetchData();
    }
  }, [data]);

  return (
    // 组件的 JSX
  );
};

export default MyComponent;
