如果你想将它保存在客户端，然后你需要将文件下载到客户端并让他的浏览器处理它 - 你不能强迫任何浏览器保存在任何位置，甚至可以调出保存对话框。您可以在非常非常有限的情况下进行，但它们不适用于99.99％的浏览器和设置组合。



如果要将其保存在服务器上，那么你需要编写自己的模拟另存为对话框，以允许用户选择服务器位置 - 但我真的不会因为（a）困难而且（b）有点安全风险。

If you want to save it at the client, then you need to download the file to the client and let his browser take care of it - you can't force "any browser" to save in any location, or even to bring up a save dialog. You can do it under very, very limited circumstances, but they do not apply to 99.99% of browser and setup combinations.

If you want to save it at the server, then you would need to write your own mock "save as" dialog to allow the user to select the server location - but I really wouldn't as it would be (a) difficult and (b) somewhat of a security risk...
