javascript - 有没有办法为 urlCreator.createObjectURL(blob) 创建文件名

Question

我对 Javascript 不是很熟悉，有什么方法可以让我创建自己的文件名吗？它会打开一个新选项卡，并且文件名采用 Guid 格式。

if (urlCreator && headers['content-type'] != 'application/octet-stream') {
  // Fallback to $window.location method
  try {
    // Prepare a blob URL
    // Use application/octet-stream when using $window.location to force download
    var objectUrl = urlCreator.createObjectURL(blob);
    $window.open(objectUrl);
    success = true;
  } catch (ex) {
    //console.log("Download link method with $window.location failed with the following exception:");
    //console.log(ex);
  }
}

您可以使用 FileSaver.js为此:

var FileSaver = require('file-saver');
var blob = new Blob(["Hello, world!"], {type: "text/plain;charset=utf-8"});
FileSaver.saveAs(blob, "hello world.txt");
