File Upload Angular 2 & Sails Js

Question

I am trying to upload multiple files from Angular 2 and Sails Js server. I want to place file inside public folder of SailJs App.

The file is uploaded from Angular 2 App by getting file from an event fired. the code for single file upload is as follows:

Angular 2 service:

fileChange(event: any): Promise<string>  {
    let fileList: FileList = event.target.files;
    if(fileList.length > 0) {
        let file: File = fileList[0];
        let formData:FormData = new FormData();
        formData.append('myFile', file, file.name);
        let headers = new Headers();
        let cToken = this.cookie.getCookie("token");
        headers.append('Authorization', 'Bearer ' + cToken);
        headers.append('Content-Type', undefined);

        //headers.append('Content-Type', 'multipart/form-data');

        headers.append('Accept', 'application/json');
        let options: RequestOptionsArgs = { headers: headers, withCredentials: true }
        return new Promise((resolve, reject) => {
            this.http.post( this.apiEndpoint + "project/reffile/add/all", formData, options).toPromise()
            .then(response => {
                // The promise is resolved once the HTTP call is successful.
                let jsonData = response.json();
                if (jsonData.apiStatus == 1) {
                    resolve(jsonData);
                }
                else reject(jsonData.message);
            })
            // The promise is rejected if there is an error with the HTTP call.
            // if we don't get any answers the proxy/api will probably be down
            .catch(reason => reject(reason.statusText));
        });
    }
}

SailsJs method:

  /**
   * `FileController.upload()`
   *
   * Upload file(s) to the server's disk.
   */
   addAll: function (req, res) {

    // e.g.
    // 0 => infinite
    // 240000 => 4 minutes (240,000 miliseconds)
    // etc.
    //
    // Node defaults to 2 minutes.
    res.setTimeout(0);

    console.log("req.param('filename')");
    console.log(req.param('filename'));
    req.file('myFile')
    .upload({

      // You can apply a file upload limit (in bytes)
      maxBytes: 1000000

    }, function whenDone(err, uploadedFiles) {
      if (err) return res.serverError(err);
      else return res.json({
        files: uploadedFiles,
        textParams: req.allParams()
      });
    });
  },

after posting form, I didn't get file in HTTP call response also not able to console.log(req.param('filename')); .

please help me what I am doing wrong here. I also tried changing/removing header, but still not working,

some expert says that HTTP currently cant upload files, need to use native XHR request for this. please view Thierry Templier 's answer here

Try specifying a directory for file upload:

    req.file('file').upload({
        dirname: '../../assets/uploads'
    },function (err, files) {
        if (err) return res.serverError(err);
        var fileNameArray = files[0].fd.split("/");
        var fileName = fileNameArray[fileNameArray.length - 1];
        console.log("fileName: ",fileName);
    });

To access the uploaded file - you can append the fileName to the upload directory that you have specified. File will be accessible
