如何在djangorestframework中为我正在写入的csv文件创建download api端点

import csv
from django.http import HttpResponse
from rest_framework.views import APIView

class DownloadCSV(APIView):
    def get(self, request):
        # 创建一个CSV文件
        response = HttpResponse(content_type='text/csv')
        response['Content-Disposition'] = 'attachment; filename="data.csv"'

        # 写入CSV文件的数据
        writer = csv.writer(response)
        writer.writerow(['Column 1', 'Column 2', 'Column 3'])
        writer.writerow(['Data 1', 'Data 2', 'Data 3'])

        return response

from django.urls import path
from .views import DownloadCSV

urlpatterns = [
    path('download-csv/', DownloadCSV.as_view(), name='download_csv'),
]
