Upload monitoring progress about form-data HOT 11 CLOSED

i try to listen for uploading data events via request.post interface (npm request) but it doest work. example code

var form = new FormData();
var uploadFile = fs.createReadStream($scope.data.pathFile);
var r = request.post({uri: url, jar: false, headers: {'X-To-Access-Token': token}}, function (error, response, body){
// response when uploading is done
})

form = r.form();
form.append('file', uploadFile);
form.getLength(function(err, len) {
r.setHeader('Content-Length', len);
});

r.on('data', function (data) {
// have nothing here
})

uploadFile.on('data', function (chunk) {
//its event for read data, not for uploading
})

what i did wrong?

@miukki It took me some time to understand what you were trying to do. I hope I got it right. :)
Here is example of progress tracker when FormData used with Request: https://github.com/felixge/node-form-data/pull/56/files#diff-3b8080b944f5c64eb2514fe942b7c60fR60

Let me know if it works for you.

There is no progress event yet (it might be added with new readable streams, nobody knows for sure yet),
as for now form itself is a stream, so you can listen for data events and get uploading chunks.

Let me know if you have more questions.

I see. Thanks for your help.

Seems like your question is about https://github.com/mikeal/request, but if you can tell us more details on what you're trying to do and what is your environment (node version and whatnot) it might help.

can't listen for data events , need get uploading chunks for progress bar . yes im using https://github.com/mikeal/request and i try to listen event

         r.on('data', function (chunk) {
           data.chunk += chunk.length; // so i need data.chunk for progress-bar-uploader  
           console.log(data.chunk);
         })

node version
// process.version
"v0.10.18"

//form-data version
"version": "0.1.2"

//request npm version
"version": "2.27.0"

all part of code

       var form = new FormData();
       var uploadFile = fs.createReadStream($scope.data.pathFile);

       $scope.data.chunk = 0;
       $scope.data.sizeFile = fs.statSync($scope.data.pathFile).size;

       var r = request.post({uri: $scope.data.content_upload_url, jar: false, headers: {'X-To-Access-Token': $token}}, function (error, response, body) {
           console.log('upload done'); //its work/ but i need listen event-uploading
           $scope.ui.loading = false;

           if ((response && response.statusCode == 200) || (response && response.statusCode == 201)) {
               addLog('success upload file');
           } else {
               addLog({type: 'error', data: 'error upload file'}, true);
           };

           apply();
       });

       form = r.form();
       form.append('file', uploadFile);  
       form.getLength(function(err, len) {
           r.setHeader('Content-Length', len);
       });

       //events ReadStream
       uploadFile.on('error', function () {
          addLog({type: 'error', data: ('Error to read file! ' +  $scope.data.pathFile)}, true); 
       });

       uploadFile.on('open', function () {
          addLog('Reading file ' +  $scope.data.pathFile); 
          $scope.ui.progress = true;
          $scope.ui.progressText = 'Reading file: ';
          apply();
       });

       uploadFile.on('data', function (chunk) {
           $scope.data.chunk += chunk.length;apply();
       });

       //event Response
       /* this code didnt get me data.chunk.length
       r.on("response", function (res) {

         var seen = 0
         r.on('data', function (chunk) {
           seen += chunk.length;
           console.log('seen', seen);
         })

       });
       */
