Open a PDF in a new window of the browser with angularjs - angularjs

Question

I'm new to angular js and I wish to open a PDF document in a new window of the browser after pressing a button.
I make a GET request with $http.get() at front end, at backend there is a Java rest service that respond to the GET and generates a PDF. I wish to open this PDF on the browser.
If is not possible to open the PDF in this way then at least open any PDF with AngularJs, how could I do this?
#GET
#Path("/printPdf")
public Response printService(){
//generates the pdf
File reportFile = new File(filePath);
String name = reportName + "." + "pdf";
ResponseBuilder response = Response.ok(new TemporaryFileInputStream(reportFile));
response.header("Content-Disposition", "attachment; filename=" + name);
response.header("Content-Type", "application/pdf");
response.header("Access-Control-Expose-Headers", "x-filename");
response.header("x-filename", name);
return response.build();
}
this is what there is at backend to generate the response in the rest service.

Answer 1

If you had something like this:
var myPdfUrl = 'something'
$http.get(myPdfUrl);
Do this instead:
var myPdfUrl = 'something'
$window.open(myPdfUrl);
If instead you have something like this:
$http
.get(generatePdfUrl)
.then(function(data){
//data is link to pdf
});
Do this:
$http
.get(generatePdfUrl)
.then(function(data){
//data is link to pdf
$window.open(data);
});

Answer 2

Maybe this can help,in the case of you have something like this :
$http.get('generatePdfUrl')
.then(function (data) { // data is your url
var file = new Blob([data], {type: 'application/pdf'});
var fileURL = URL.createObjectURL(file);
});
Then use your service in controller and do
$window.open(fileURL);
