Python/Django:提供一个可从io.BytesIO缓冲区下载的zip文件 [英] Python/Django: Offering a zip file for download from io.BytesIO buffer

问题描述

我正在尝试将zip文件放入io.BytesIO缓冲区中，然后提供该文件以供下载.以下是我所拥有的(更长的views.py的一部分，我只是在发布相关部分).

I'm trying to put a zip file into an io.BytesIO buffer and then offer that for download. Below is what I've got (part of a longer views.py, I'm just posting the relevant part).

但是我收到以下错误消息:

AttributeError at 'bytes' object has no attribute 'read'

有人可以告诉我我在做什么错吗?

from django.http import HttpResponse
from wsgiref.util import FileWrapper
from zipfile import *
import io

buffer = io.BytesIO()

zipf = ZipFile(buffer, "w")
zipf.write ("file.txt")
zipf.close()

response = HttpResponse(FileWrapper(buffer.getvalue()), content_type='application/zip')
response['Content-Disposition'] = 'attachment; filename=file.zip'

return response

告诉我错误来自以下行:

It's telling me the error is coming from the line:

response = HttpResponse(FileWrapper(buffer.getvalue()), content_type='application/zip')

推荐答案

您需要以字节模式('b')

尝试更改

buffer = io.BytesIO()
zipf = ZipFile(buffer, "w")
zipf.write ("file.txt")
zipf.close()

到

zipf = zipfile.ZipFile("hello.zip", "w")
zipf.write("file.txt")
zipf.close()
response = HttpResponse(io.open("hello.zip", mode="rb").read(), content_type='application/zip')
