Downloading and saving files from server using AngularJS

I'd guess that you're not getting a byte array back from your $http.get call. Try adding:

vm.download = function (filename) {var config = {headers: {        'Accept': "image/jpeg"    }};$http.get('api/files/download/' + filename, config).then(function (response)             {        var myBuffer= new Uint8Array( response.data );    var data = new Blob([myBuffer], {type: 'image/jpeg;charset=UTF-8'});    FileSaver.saveAs(data, filename);        })}

I have a special download service in angular that works very well and simple:

(function () {    angular.module('common')        .factory('downloadService', ['$http', '$window', 'contentDispositionParser',            function ($http, $window, contentDispositionParser) {                return {                    downloadFile: downloadFile                };                function downloadFile(url, request)                {                    $http({                        url: url,                         method: 'GET',                        params: request,                        responseType: 'blob'                    })                    .success(function (data, status, headers, config){                        var disposition = headers('Content-Disposition');                        var filename = contentDispositionParser.getFileName(disposition);                        $window.saveAs(data, filename); // This is from FileSaver.js                    });                }            }]);})();

Filesaver.js is from here.ContentDispositionParser you can use anything or write yourself, it's only used for getting the proper filename, since it is apparently not an easy task, but not directly connected to saving the file itself (you might add the name in js e.g.)
