如何在AngulaJS中更改文件名下载导出可执行文件？

$scope.downloadFile = function() {
  // 下载文件的逻辑
};

var fileContent = '这是文件的内容';
var fileType = 'text/plain';
var blob = new Blob([fileContent], { type: fileType });

var downloadUrl = URL.createObjectURL(blob);

var downloadLink = document.createElement('a');
downloadLink.href = downloadUrl;
downloadLink.download = 'newFileName.txt';

document.body.appendChild(downloadLink);
downloadLink.click();

$scope.downloadFile = function() {
  var fileContent = '这是文件的内容';
  var fileType = 'text/plain';
  var blob = new Blob([fileContent], { type: fileType });
  var downloadUrl = URL.createObjectURL(blob);

  var downloadLink = document.createElement('a');
  downloadLink.href = downloadUrl;
  downloadLink.download = 'newFileName.txt';

  document.body.appendChild(downloadLink);
  downloadLink.click();
};
