就是界面上有个按钮，然后点击之后，后台会生成一个文件，比如log文件，然后当生成完成，就可以下载了。
由于第一次处理这种实时文件生成，不太明白怎么实现。谢谢

Return a downloadable file. As long as you add Content-Disposition=attachment; filename="anyfilename.xxx" in the header of the returned HTTP response, the browser will pop up a download dialog box to prompt the user to download.
The file content background is the same whether it is read from a local file or a string produced by a program. It is stuffed into the HttpResponse object and returned in the corresponding view. Be careful not to keep users waiting for too long.
For an official example of generating a csv file, please refer to: https://docs.djangoproject.co...
