Multer: Multer does not save anything to me

[imrefazekas]

Hello,

here is my code I'm using on server side::

var uploader = multer({
    dest: 'upload/',
    filename: function (req, file, cb) {
        console.log('>>>>>>>>>>>>>>>>>>>', file);
        cb( null, file.fieldname + '-' + Date.now() );
    }
});
var uploadHandler = function(req, res, next){
    if( req.url !== '/system/upload' || req.method !== 'POST') return next();

    uploader.array('x-files')( req, res, function( err ){
        console.log('???????????????', err, req.files, req.file);
    } );
};
...
.use( uploadHandler )

On client side vanilla javascript:

upload: function( url, files ){
    var self = this;

    var formData = new FormData();
    formData.append( 'x-files', Array.isArray(files)?files:[files] );

    var request = new XMLHttpRequest();
    request.open('POST', url, true);

    request.send( formData );
}

The line

console.log('???????????????', err, req.files, req.file); 

works, I see '???????????????' on the screen but err, req.files, req.file are all undefined and the filename function is never called and nothing is stored in the folder upload

No error, yet no files are stored or set in the req object...

Could you console.log req.headers before passing it to multer?

[imrefazekas]

Sure, here it is:

{ host: 'localhost:8080',
  'content-type': 'multipart/form-data; boundary=----WebKitFormBoundary0PmZBJD6r6CULTMU',
  origin: 'http://localhost:8080',
  'content-length': '154',
  connection: 'keep-alive',
  accept: '*/*',
  'user-agent': 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_10_4) AppleWebKit/600.7.12 (KHTML, like Gecko) Version/8.0.7 Safari/600.7.12',
  referer: 'http://localhost:8080/work',
  'accept-language': 'en-us',
  'accept-encoding': 'gzip, deflate' }

Strangely enough, with version 0.1 it worked fine, I only refreshed to version v1 today...

Could you try the following code:

var upload = multer({ dest: 'upload/' }).array('x-files')

function uploadHandler (req, res, next) {
  if (req.url !== '/system/upload' || req.method !== 'POST') return next()

  console.log('STARTING UPLOAD')

  upload(req, res, function (err) {
    if (err) return next(err)

    console.log('UPLOAD FINISHED')
    console.log(req.files)
  })
}

app.use(uploadHandler)
