python - HttpResponse Django 不更改文件名

Question

我遵循了 3 个答案:

Generating file to download with Django
Make Django return response as a "different filename"
Adding a variable in Content disposition response file name-python/django

我的POSTMAN是v4.10.3

class SBrandJobRawDataView(APIView):
    permission_classes = []
    authentication_classes = (TokenAuthentication,)

    def get(self, request, format=None):
        data = {
            "message": _("GET method is not allowed"),
        }
        return Response(data=data, status=status.HTTP_400_BAD_REQUEST, )

    def post(self, request, format=None):
        from_date = request.data.get('from_date')
        to_date = request.data.get('to_date')
        queryset = get_raw_sbrand_record(from_date, to_date)
        filename = f"From_{from_date.get('year')}-{from_date.get('month')}-{from_date.get('day')}_to_" \
                   f"{to_date.get('year')}-{to_date.get('month')}-{to_date.get('day')}.xlsx"
        # Allow only last file stay in the server.
        clean_dir("xlsx")

        # Create Excel report
        gen_sbrand_report(queryset, filename)

        # Open file
        abs_file = os.getcwd() + '/' + filename
        xls_file = open(abs_file, 'rb')

        # Response with attachment
        response = HttpResponse(xls_file,
                            content_type='application/vnd.openxmlformats-officedocument.spreadsheetml.sheet')
        response['Content-Disposition'] = f"attachment; filename={filename}"
        import pdb; pdb.set_trace()
        return response

我知道我正在混合 Django 和 Django REST 响应。如果我使用 from rest_framework.response import Response 我会收到错误

这是调试行

(Pdb) response['Content-Disposition']
'attachment; filename=From_2017-1-1_to_2017-12-25.xlsx'

问题:
我得到的 response.xlsx 不是我指定的名称。

Answer 1

试试这个:

from django.utils.http import urlquote
response['Content-Disposition'] = 'attachment; filename={}'.format(urlquote(filename))
