view.py:

from django.http import HttpResponse from django.shortcuts import render from .pc_or_mobile import judge_pc_or_mobile def index(request): ua = request.META.get("HTTP_USER_AGENT") mobile = judge_pc_or_mobile(ua) if not mobile: return HttpResponse('请用手机访问') else: return render(request, 'index.html')
通过以上优化，你现在可以在Django项目中轻松判断用户访问来源是PC端还是手机端。这个简单而有效的方法可以帮助你更好地适配不同的设备，提供更友好的用户体验。确保在视图中根据判断结果返回相应的页面，使你的网站在各种设备上都能正常展示。如果在使用过程中遇到任何问题，欢迎随时查阅Django文档或向社区寻求帮助。祝你的项目开发顺利，用户体验优越！
