如何在django中下载文件

from django.http import FileResponse

def download_file(request):
    file_path = '/path/to/file'  # 文件的绝对路径
    file_name = 'filename.ext'  # 文件名

    response = FileResponse(open(file_path, 'rb'))
    response['Content-Disposition'] = f'attachment; filename="{file_name}"'
    return response

from django.urls import path
from .views import download_file

urlpatterns = [
    path('download/', download_file, name='download'),
]

<a href="{% url 'download' %}">点击下载文件</a>
