使用formidable将上传的文件流式传输到s3

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

const http = require('http');

http.createServer((req, res) => {
  if (req.url === '/upload' && req.method.toLowerCase() === 'post') {
    const form = new formidable.IncomingForm();

    // 设置上传目录和文件名
    form.uploadDir = './temp';
    form.on('file', (name, file) => {
      // 将文件流式传输到S3
      const readStream = fs.createReadStream(file.path);
      const params = {
        Bucket: 'your-bucket-name',
        Key: 'your-file-key',
        Body: readStream
      };

      // 在此处调用适合的S3上传方法，将文件流传输到S3
      // 示例：s3.upload(params, (err, data) => { ... });
    });

    // 完成文件上传处理
    form.parse(req, (err, fields, files) => {
      res.writeHead(200, { 'Content-Type': 'text/plain' });
      res.write('File uploaded successfully');
      res.end();
    });
  } else {
    res.writeHead(404, { 'Content-Type': 'text/plain' });
    res.write('Not found');
    res.end();
  }
}).listen(8080);
