JS PDF Blob empty page












0















I'm using external Rest API to get spedition label for package. In response I have:



%PDF-1.4n%����n6 0 objn<</ColorSpace[/Indexed/DeviceRGB 255( [...]


Now I need to display PDF in browser



var xhr = new XMLHttpRequest();
xhr.open('POST', '/Order/CreateShipmentInpost', true);
xhr.setRequestHeader('Content-type', 'application/x-www-form-urlencoded');
xhr.responseType = 'arraybuffer';
xhr.onload = function (e) {
if (this.status == 200) {
var blob = new Blob([this.response], { type: "application/pdf" });
var link = document.createElement('a');
link.href = window.URL.createObjectURL(blob);
link.download = "Report.pdf";
link.click();
}
};
xhr.send($.param(data));


In generated PDF file is only blank page. I don't know why content is not showing.



PDF empty page



I'm using responseType = 'arraybuffer'. Controller returns:



 return File(Encoding.UTF8.GetBytes(data, MediaTypeNames.Application.Pdf);


I also tried to return json or string, but PDF was always empty.
