返回 zip 以从 django 中的视图下载
我尝试在 Django 应用程序中下载 zip 文件。
我应该如何从视图中返回它？
我尝试了下面的代码，但我在浏览器中收到了某种警报，其中包含我的 zip 中的文件内容。
我做错了什么？
def download_logs(request):
date = datetime.datetime.now().__str__().replace(" ", "_").split(".")[0]
os.system("df -h . > /tmp/disk_space")
response = HttpResponse(mimetype='application/zip')
response['Content-Disposition'] = 'filename=logs_%s.zip' % date
files = []
files.append("/tmp/disk_space")
buffer = StringIO()
zip = zipfile.ZipFile(buffer, "w", zipfile.ZIP_DEFLATED)
for name in files:
file = open(name, "r")
zip.writestr(name, file.read())
file.close()
zip.close()
buffer.flush()
ret_zip = buffer.getvalue()
buffer.close()
response.write(ret_zip)
return response
I try to download a zip file in my Django application.
How should I return it from the view?
I tried the code below, but I get some kind of alert in the browser with the content of the file inside my zip.
What am I doing wrong?
def download_logs(request):
date = datetime.datetime.now().__str__().replace(" ", "_").split(".")[0]
os.system("df -h . > /tmp/disk_space")
response = HttpResponse(mimetype='application/zip')
response['Content-Disposition'] = 'filename=logs_%s.zip' % date
files = []
files.append("/tmp/disk_space")
buffer = StringIO()
zip = zipfile.ZipFile(buffer, "w", zipfile.ZIP_DEFLATED)
for name in files:
file = open(name, "r")
zip.writestr(name, file.read())
file.close()
zip.close()
buffer.flush()
ret_zip = buffer.getvalue()
buffer.close()
response.write(ret_zip)
return response

您应该告诉浏览器将响应视为文件附件。
来自 docs，你应该这样做：
You should tell the browser to treat the response as a file attachment.
From the docs, you should do something like:
