Download a PDF received from an API with Angularjs

Question

I have an API that returns me a PDF file.

I want to make the angle hit this route and force the download of the PDF file.

Today I do so:

var blob = new Blob([arquivo], {type: "application/pdf"});
saveAs(blob, 'arquivo.pdf');

The download works, but the pdf file comes blank. If I hit the route manually, the file comes complete.

Answer 1

The responseType in the request.

The problem was not at this point, but at the request call, where the GET was made, it was missing to specify the responseType.

That’s how the code works:

$http.get('/api/download/' + uid, {responseType:'arraybuffer'});
