看了文档中的demo 与示例 没有找到，如何 返回储存后图片的路径
求有经验的帮助

Answer 1

var http = require('http'),
    path = require('path'),
    os = require('os'),
    fs = require('fs');

var Busboy = require('busboy');

http.createServer(function(req, res) {
  if (req.method === 'POST') {
    var busboy = new Busboy({ headers: req.headers });
    busboy.on('file', function(fieldname, file, filename, encoding, mimetype) {
      var saveTo = path.join(os.tmpDir(), path.basename(fieldname));
      file.pipe(fs.createWriteStream(saveTo));//saveTo就是存储路径
    });
    busboy.on('finish', function() {
      res.writeHead(200, { 'Connection': 'close' });
      res.end("That's all folks!");
    });
    return req.pipe(busboy);
  }
  res.writeHead(404);
  res.end();
}).listen(8000, function() {
  console.log('Listening for requests');
});

不是已经写了么，busboy才不帮你存呢，你爱存哪存哪。
