我该如何解决?

推荐答案

如果要以编程方式将ancor标记注入DOM中，请确保不要过早清除它.

If you are injecting an ancor tag into DOM programmatically as your solution, make sure you do not clear that up too soon.

对我来说100ms可以正常工作，但是由于无论哪种方式都不可见，我选择清除DOM的延迟时间为1秒.

For me 100ms worked fine but since it's invisible either way I chose 1 second delay on clearing DOM up.

示例代码:

this.fileApi.download(<your args>).subscribe((data: Blob) => {
    const url = window.URL.createObjectURL(data);
    const a = document.createElement('a');
    a.style.display = 'none';
    a.href = url;

    // the filename you want
    a.download = <your filename>;
    document.body.appendChild(a);
    a.click();

    setTimeout(() => {
      window.URL.revokeObjectURL(url);
      document.body.removeChild(a);
    }, 1000);
  })
