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).

Answer 1

what i did to solve this was.

var formData = new FormData(document.getElementById('myFormId'));

then in my service

                var deferred = $q.defer();
                $http.post('myurl', formData, {
                    cache: false,
                    contentType: false,
                    processData: false,
                })
                    .success(function (response) {
                        deferred.resolve(response);
                    })
                    .error(function (reject) {
                        deferred.reject(reject);
                    });
                return deferred.promise;
