couchdb curl命令如何转换为nano或node的http库？

const nano = require('nano')('http://localhost:5984'); // 替换为CouchDB的URL

// 创建数据库
nano.db.create('mydb', (err, body) => {
  if (err) {
    console.log('创建数据库失败:', err);
    return;
  }
  console.log('创建数据库成功:', body);
});

// 插入文档
const mydb = nano.db.use('mydb');
const doc = { name: 'John', age: 30 };
mydb.insert(doc, (err, body) => {
  if (err) {
    console.log('插入文档失败:', err);
    return;
  }
  console.log('插入文档成功:', body);
});

const http = require('http');

// 创建数据库
const options = {
  hostname: 'localhost',
  port: 5984,
  path: '/mydb', // 替换为数据库的路径
  method: 'PUT'
};

const req = http.request(options, (res) => {
  console.log(`状态码: ${res.statusCode}`);
  res.on('data', (chunk) => {
    console.log(`响应主体: ${chunk}`);
  });
});

req.on('error', (err) => {
  console.error(`请求失败: ${err}`);
});

req.end();

// 插入文档
const postData = JSON.stringify({ name: 'John', age: 30 });

const options = {
  hostname: 'localhost',
  port: 5984,
  path: '/mydb', // 替换为数据库的路径
  method: 'POST',
  headers: {
    'Content-Type': 'application/json',
    'Content-Length': postData.length
  }
};

const req = http.request(options, (res) => {
  console.log(`状态码: ${res.statusCode}`);
  res.on('data', (chunk) => {
    console.log(`响应主体: ${chunk}`);
  });
});

req.on('error', (err) => {
  console.error(`请求失败: ${err}`);
});

req.write(postData);
req.end();
