Django File Download Tutorial

To achieve the function of downloading files, you can implement the following steps in Django.

1. Create a view function in the views.py file to handle file download requests.

from django.http import FileResponse
import os

def download_file(request, file_path):
    file_path = os.path.join(settings.MEDIA_ROOT, file_path)
    if os.path.exists(file_path):
        with open(file_path, 'rb') as f:
            response = FileResponse(f)
            response['Content-Disposition'] = 'attachment; filename="%s"' % os.path.basename(file_path)
            return response
    else:
        # 文件不存在的处理逻辑
        return HttpResponse("File not found", status=404)

1. Configure the URL routing for this view function in the urls.py file.

from django.urls import path
from . import views

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

1. Add a download link in the template file and call the corresponding view function.

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

In this way, when users access the link, it will trigger the file download function, and the browser will prompt a file download dialog where users can choose to save the file or open it directly.
