django打开一个zip文件供用户下载

Question

Django 1.7, Python 3.4, windows apache 2.4.12 + wsgi

In my program, I generate some csv files and put them in a zip file. I would like to let the user download the zip file, either force download (after file is generated and render response) or a click of button (after display result, user has to click a button to download.)

Currently I am forcing them to download once the zip file is generated on the server.

I have referenced the following links and come up with my code below. But it is always give me this error "'charmap' codec can't decode byte 0x8d in position 80: character maps to " I tried to set it with utf-8 and ascii, and similar errors will be given.

referenced links:

• django download file from server to user's machine,or read online
• how to serve downloadable zip file in django
• https://djangosnippets.org/snippets/365/
• Generating file to download with Django

Anyone know why am I getting this error and how to get this to work?

Thank you very much!

zip_filename = time.strftime("%Y%m%d") + ".zip"
with zipfile.ZipFile(zip_filename, mode='a', compression=zipfile.ZIP_DEFLATED) as zf:
    for s in sql_request:
        // generate csv files
        zf.write(csv_file)

// close zf

zip_file = open(zip_filename, 'r')
response = HttpResponse(zip_file, content_type='application/force-download')
response['Content-Disposition'] = 'attachment; filename="%s"' % 'foo.zip'
return response

如果您使用的是Windows，则可能需要更改open行以包含b标志 。

zip_file = open(zip_filename, 'rb')
