推荐答案

您可能不知道.某些浏览器甚至在用户决定如何处理文件之前就开始下载.但是，如果下载已完成，也许可以让您的Web服务器记录日志.这可能是您可以获得的最可靠的结果.

You can't know that. Some browsers even start the download before the user decides what to do with the file. But perhaps you can get your webserver to log if the download has been completed. That's probably the most reliable result you can get.
