Angularjs – Failed to load PDF document – Angular JS – BLOB

I am trying to get PDF document from Web API, and want to show in Angular App. Getting "Failed to load PDF document error".
I have followed
"AngularJS: Display blob (.pdf) in an angular app" post.
Whereas, i can download the same file successfully by following "Download file from an ASP.NET Web API method using AngularJS" post.

Looks like i am getting the file as "Chunked Transfer Encoded". Somehow this is not getting decoded when trying to show in angular app. Please advise.

Web API Code:

HttpResponseMessage result = null;
        var localFilePath = @"C:\Test.pdf";

        if (!File.Exists(localFilePath))
            result = Request.CreateResponse(HttpStatusCode.Gone);
        {// serve the file to the client
            result = Request.CreateResponse(HttpStatusCode.OK);
            result.Content = new StreamContent(new FileStream(localFilePath, FileMode.Open, FileAccess.Read));                
            result.Content.Headers.ContentDisposition = new System.Net.Http.Headers.ContentDispositionHeaderValue("attachment");
            result.Content.Headers.ContentType = new MediaTypeHeaderValue("application/pdf");
            result.Content.Headers.ContentDisposition.FileName = "Test.pdf";
            result.Content.Headers.Add("x-filename", "Test.pdf");

        return result;

Angular Controller:

   myModule.controller("pdfviewerController", function ($scope, $http, $log, $sce) {
$'/api/Sample/GetTestFile', {responseType:'arraybuffer'})
 .success(function (response) {      
  var file = new Blob([response], { type: 'application/pdf' });
  var fileURL = URL.createObjectURL(file);
  $scope.content = $sce.trustAsResourceUrl(fileURL);            

HTML Template:

<embed ng-src="{{content}}" style="width:200px;height:200px;"></embed>

Best Solution

problem is there in controller. {responseType:'arraybuffer'} is verymuch required. For $http.get - It should be second parameter. For $ - It should be third parameter.

In above case, i am using $ and i have passed {responseType:'arraybuffer'} as second parameter.

$'/api/Sample/GetTestFile', {responseType:'arraybuffer'})

Corrected code

$'/api/Sample/GetTestFile','', {responseType:'arraybuffer'})
