【Django】Django用户认证: 利用Django Auth模块实现用户注册、登录与登出

from django.contrib.auth import authenticate, login, logout
from django.contrib.auth.models import User
from django.http import HttpResponse
 
# 用户登录视图
def user_login(request):
    if request.method == 'POST':
        username = request.POST['username']
        password = request.POST['password']
        user = authenticate(request, username=username, password=password)
        if user is not None:
            login(request, user)
            return HttpResponse("登录成功")
        else:
            return HttpResponse("用户名或密码错误")
    else:
        return HttpResponse("仅接受POST请求")
 
# 用户注册视图
def register_user(request):
    if request.method == 'POST':
        username = request.POST['username']
        password = request.POST['password']
        user = User.objects.create_user(username=username, password=password)
        return HttpResponse("注册成功")
    else:
        return HttpResponse("仅接受POST请求")
 
# 用户登出视图
def user_logout(request):
    logout(request)
    return HttpResponse("登出成功")

这段代码提供了用户登录、注册以及登出的简单视图函数示例。在实际应用中，你需要将这些视图函数与URL配置对应起来，并且在实际环境中应该加入更多的安全措施，比如密码散列、CSRF保护等。
