Agular2 + typescript + file upload

Question

I am creating an angular2 project, in which my requirement is to upload a file and send some parameters from client to server(Spring Rest Server). I have tried Formdata Interfac

Answer 1

Your HTML should be:

So you will get file in component as:

uploadFile(event) {
  let files = event.target.files;
  if (files.length > 0) {
    console.log(file); // You will see the file
    this.service.uploadFile(file);
  }
}

And in service:

uploadFile(file) {
  let formData: FormData = new FormData();
  formData.append('file', file, file.name);

  this.http.post(url, formData, request_options)
}

Then you will get file in with file key in request data.
