new XMLHttpRequest() 封装 URL.createObjectURL报错

Question

function getExport(url, token, title) {
  let xhr = new XMLHttpRequest();
  xhr.open("GET", url, true);
  xhr.setRequestHeader("Authorization", "Bearer " + token);
  xhr.onload = function (e) {
    if (this.status === 200) {
      let blob = this.response;
      let ojA = document.createElement("a");
      let urlData = window.URL.createObjectURL(blob);
      ojA.href = urlData;
      ojA.download = title;
      ojA.click();
      window.URL.revokeObjectURL(urlData);
    }
  };
  xhr.send();
}

调用方法为什么报错

Export
public.js:347 Uncaught TypeError: Failed to execute 'createObjectURL' on 'URL': No function was found that matched the signature provided.

at XMLHttpRequest.xhr.onload (public.js:347)
