将xml文件发布到nodjs服务器？

const http = require('http');
const fs = require('fs');
const xml2js = require('xml2js');

const server = http.createServer((req, res) => {
  if (req.url === '/xml') {
    // 读取XML文件
    fs.readFile('path/to/xml/file.xml', 'utf8', (err, data) => {
      if (err) {
        res.statusCode = 500;
        res.end('Error reading XML file');
      } else {
        // 解析XML文件为JavaScript对象
        xml2js.parseString(data, (err, result) => {
          if (err) {
            res.statusCode = 500;
            res.end('Error parsing XML');
          } else {
            // 设置HTTP头
            res.setHeader('Content-Type', 'application/xml');
            // 发送XML响应
            res.end(data);
          }
        });
      }
    });
  } else {
    res.statusCode = 404;
    res.end('Not found');
  }
});

server.listen(3000, () => {
  console.log('Server is running on port 3000');
});
