如何自动为每个帖子创建带有新网址的子页面[NodeJS]

npm install express

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

const posts = [];

app.post('/posts', (req, res) => {
  const { title, content } = req.body;
  
  // 生成一个唯一的ID
  const id = generateUniqueId();
  
  // 创建一个帖子对象
  const post = {
    id,
    title,
    content,
    url: `https://example.com/posts/${id}` // 生成帖子的URL
  };
  
  // 将帖子保存到数组中
  posts.push(post);
  
  res.status(201).json(post);
});

app.get('/posts/:id', (req, res) => {
  const { id } = req.params;
  
  // 在帖子数组中查找匹配的帖子
  const post = posts.find(post => post.id === id);
  
  if (!post) {
    return res.status(404).json({ error: 'Post not found' });
  }
  
  res.json(post);
});

const port = 3000;

app.listen(port, () => {
  console.log(`Server is running on port ${port}`);
});
