使用Django生成文件下载 [英] Generating file to download with Django

问题描述

可以制作zip存档并提供下载，但仍然不能将文件保存到硬盘驱动器？

Is it possible to make a zip archive and offer it to download, but still not save a file to the hard drive?

推荐答案

要触发下载，您需要设置 Content-Disposition 标题：

To trigger a download you need to set Content-Disposition header:

from django.http import HttpResponse
from wsgiref.util import FileWrapper

# generate the file
response = HttpResponse(FileWrapper(myfile.getvalue()), content_type='application/zip')
response['Content-Disposition'] = 'attachment; filename=myfile.zip'
return response

如果不想要文件磁盘需要使用 StringIO

If you don't want the file on disk you need to use StringIO

import cStringIO as StringIO

myfile = StringIO.StringIO()
while not_finished:
    # generate chunk
    myfile.write(chunk)

您还可以设置 Content-Length 标题：

response['Content-Length'] = myfile.tell()
