Multipart request with AngularJS

Question

I have an API endpoint to which I must send a multipart HTTP request, composed of two parts, file (a file system file) and data (a JSON object).

Have you tried something like this:

$httpProvider.defaults.transformRequest = function(data) {
  if (data === undefined){
    return data;
  }

  var formData = new FormData();
  for (var key in data){
    if(typeof data[key] == 'object' && !(data[key] instanceof File)){
      formData.append(key, JSON.stringify(data[key]));
    }else{
      formData.append(key, data[key]);
    }
  }
  return formData;
};
