我是NodeJS的初学者，我做了一个http delete请求，但是它不工作。

const http = require('http');
const url = require('url');

const server = http.createServer((req, res) => {
  const parsedUrl = url.parse(req.url, true);
  if (req.method === 'DELETE' && parsedUrl.pathname === '/resource') {
    // 处理DELETE请求
    res.writeHead(200, {'Content-Type': 'application/json'});
    res.end(JSON.stringify({message: 'Resource deleted'}));
  } else {
    res.writeHead(405, {'Content-Type': 'application/json'});
    res.end(JSON.stringify({message: 'Method Not Allowed'}));
  }
});

server.listen(3000, () => {
  console.log('Server running at http://localhost:3000/');
});

const axios = require('axios');

axios.delete('http://localhost:3000/resource')
  .then(response => {
    console.log(response.data);
  })
  .catch(error => {
    console.error(error);
  });

const express = require('express');
const app = express();

app.delete('/resource', (req, res) => {
  res.json({message: 'Resource deleted'});
});

app.listen(3000, () => {
  console.log('Server running at http://localhost:3000/');
});

const express = require('express');
const cors = require('cors');
const app = express();

app.use(cors());

app.delete('/resource', (req, res) => {
  res.json({message: 'Resource deleted'});
});

app.listen(3000, () => {
  console.log('Server running at http://localhost:3000/');
});
