Question

我在node.js上传文件时遇到问题。我没有使用快递。并且大多数在线示例都是使用expres进行文件上传.. 感谢任何指点。

function fileUploader2(req, res, next) {
var busboy = new Busboy({ headers: req.headers });
req.pipe(busboy);

busboy.on('file', function(fieldname, file, filename, encoding, mimetype) {
    console.log('File [' + fieldname + ']: filename: ' + filename + ', encoding: ' + encoding + ', mimetype: ' + mimetype);
  //  var saveTo = path.join(os.tmpDir(), path.basename(fieldname));
    file.pipe(fs.createWriteStream('./upload/' + filename));
});
busboy.on('finish', function() {
    res.writeHead(200, { 'Connection': 'close' });
    res.end("That's all folks!");
});


res.end();

};

以上不起作用。我再次使用快递。非常感谢任何帮助。

在这里，我为你做了一个例子。它对我有用。

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

const server = http.createServer((req, res) => {
  var busboy = new Busboy({
    headers: req.headers
  });
  busboy.on('file', function(fieldname, file, filename, encoding, mimetype) {
    saveTo = `${__dirname}/${filename}`;
    file.pipe(fs.createWriteStream(saveTo));
  });
  busboy.on('finish', function() {
    res.writeHead(200, {
      'Connection': 'close'
    });
    res.end("That's all folks!");
  });
  return req.pipe(busboy);
  res.writeHead(404);
  res.end();
});

server.listen(8000, function() {
  console.log('magic at 8000');
});
