手工CMS元素-api如何获取条目中类别字段的值

const express = require('express');
const app = express();
const port = 3000;

// 模拟数据库
const items = [
  { id: 1, title: 'Item 1', category: 'Tech' },
  { id: 2, title: 'Item 2', category: 'Sports' }
];

app.get('/api/items/:id', (req, res) => {
  const itemId = parseInt(req.params.id);
  const item = items.find(i => i.id === itemId);
  if (item) {
    res.json(item);
  } else {
    res.status(404).json({ message: 'Item not found' });
  }
});

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

fetch('http://localhost:3000/api/items/1')
  .then(response => response.json())
  .then(data => {
    console.log('Category:', data.category);
  })
  .catch(error => console.error('Error:', error));

const cors = require('cors');
app.use(cors());
