如何在REACT中为连接到node.js的Axios路由创建单独的文件夹

// api.js

import axios from 'axios';

const API_BASE_URL = 'http://localhost:3000'; // 后端服务器的基本URL

export const getUsers = () => {
  return axios.get(`${API_BASE_URL}/users`);
};

export const createUser = (userData) => {
  return axios.post(`${API_BASE_URL}/users`, userData);
};

export const updateUser = (userId, userData) => {
  return axios.put(`${API_BASE_URL}/users/${userId}`, userData);
};

export const deleteUser = (userId) => {
  return axios.delete(`${API_BASE_URL}/users/${userId}`);
};

// UserList.js

import React, { useEffect, useState } from 'react';
import { getUsers } from './api'; // 引入刚刚创建的api.js文件

const UserList = () => {
  const [users, setUsers] = useState([]);

  useEffect(() => {
    // 在组件加载时获取用户列表数据
    getUsers()
      .then((response) => {
        setUsers(response.data);
      })
      .catch((error) => {
        console.error('Error fetching users:', error);
      });
  }, []);

  return (
    <div>
      <h1>User List</h1>
      <ul>
        {users.map((user) => (
          <li key={user.id}>{user.name}</li>
        ))}
      </ul>
    </div>
  );
};

export default UserList;
