在nodejs中通过POST请求将文件打印到控制台

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

const server = http.createServer((req, res) => {
  if (req.method === 'POST') {
    let data = '';
    req.on('data', chunk => {
      data += chunk;
    });
    req.on('end', () => {
      // 将接收到的文件保存到本地
      fs.writeFile('file.txt', data, err => {
        if (err) {
          console.error(err);
          res.statusCode = 500;
          res.end('Error saving file');
        } else {
          // 打印文件内容到控制台
          fs.readFile('file.txt', 'utf8', (err, fileData) => {
            if (err) {
              console.error(err);
              res.statusCode = 500;
              res.end('Error reading file');
            } else {
              console.log(fileData);
              res.statusCode = 200;
              res.end('File printed to console');
            }
          });
        }
      });
    });
  } else {
    res.statusCode = 404;
    res.end('Not Found');
  }
});

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