Sample 1

var oReq = new XMLHttpRequest();
var URLToPDF = fileUrl;
oReq.open('GET', URLToPDF, true);
oReq.responseType = 'blob';
oReq.onload = function () {
  const file = new Blob([oReq.response], { type: 'application/pdf' });
  const fileURL = URL.createObjectURL(file);

fetch(fileUrl, {
  method: 'get',
}).then((response) => response.blob())
  .then((blobContent) => {
    var blob = new Blob([blobContent], { type: 'application/pdf' });
    saveAs(blob, 'test.pdf');
  });

Answer 1

Facing similar issue with ios/chrome. As workaround tried with below solution.

      this.blobURL = URL.createObjectURL(
        new Blob([resp], {
          type: 'application/pdf;charset=utf-8;'
        })
      );
      const k = document.createElement('a');
      k.setAttribute('href', this.blobURL);
      k.setAttribute('target', '_blank');
      k.click();
