你试过node-multiparty了吗？以下是自述文件中的示例用法：

var multiparty = require('multiparty'),http = require('http'),util = require('util')

http.createServer(function(req,res) {
  if (req.url === '/upload' && req.method === 'POST') {
    // parse a file upload
    var form = new multiparty.Form();

    form.parse(req,function(err,fields,files) {
      res.writeHead(200,{'content-type': 'text/plain'});
      res.write('received upload:\n\n');
      res.end(util.inspect({fields: fields,files: files}));
    });

    return;
  }

  // show a file upload form
  res.writeHead(200,{'content-type': 'text/html'});
  res.end(
    '<form action="/upload" enctype="multipart/form-data" method="post">'+
    '<input type="text" name="title"><br>'+
    '<input type="file" name="upload" multiple="multiple"><br>'+
    '<input type="submit" value="Upload">'+
    '</form>'
  );
}).listen(8080);

作者(Andrew Kelley)recommends避免使用bodyParser,所以你是正确的避免它,但多方似乎为我解决了类似的问题.
