为Django中生成的文件生成下载路径

from django.http import FileResponse
from django.conf import settings
import os

def download_file(request, file_name):
    file_path = os.path.join(settings.MEDIA_ROOT, file_name)
    if os.path.exists(file_path):
        file = open(file_path, 'rb')
        response = FileResponse(file)
        response['Content-Disposition'] = 'attachment; filename="{}"'.format(file_name)
        return response
    else:
        # 处理文件不存在的情况
        return HttpResponse("File not found.")

from django.urls import path
from . import views

urlpatterns = [
    path('download/<str:file_name>/', views.download_file, name='download_file'),
]

<a href="{% url 'download_file' file_name %}">Download File</a>
