Handle file download from ajax post

Question

I have a javascript app that sends ajax POST requests to a certain URL. Response might be a JSON string or it might be a file (as an attachment). I can easily detect Content

Answer 1

For those looking for a solution from an Angular perspective, this worked for me:

$http.post(
  'url',
  {},
  {responseType: 'arraybuffer'}
).then(function (response) {
  var headers = response.headers();
  var blob = new Blob([response.data],{type:headers['content-type']});
  var link = document.createElement('a');
  link.href = window.URL.createObjectURL(blob);
  link.download = "Filename";
  link.click();
});
