2024--Django平台开发-Django知识点

在Django中，我们可以使用内置的用户模型User来处理用户认证，以下是一些常用的Django用户认证方法：

1. 登录用户：

from django.contrib.auth import authenticate, login
 
def my_view(request):
    username = request.POST['username']
    password = request.POST['password']
    user = authenticate(request, username=username, password=password)
    if user is not None:
        login(request, user)
        # Redirect to a success page.
        ...
    else:
        # Return an 'invalid login' error message.
        ...

2. 注销用户：

from django.contrib.auth import logout
 
def logout_view(request):
    logout(request)
    # Redirect to a success page.
    ...

3. 检查用户是否登录：

from django.contrib.auth.decorators import login_required
 
@login_required
def my_view(request):
    # Do something for the logged-in user.
    ...

4. 创建新用户：

from django.contrib.auth.models import User
 
def create_user(request):
    username = request.POST['username']
    password = request.POST['password']
    user = User.objects.create_user(username=username, password=password)
    user.save()
    # Log the user in and then redirect to a success page.
    ...

5. 检查用户是否有特定权限：

from django.contrib.auth.decorators import permission_required
 
@permission_required('polls.can_vote')
def my_view(request):
    # Code here.
    ...

这些是Django用户认证的常用方法，可以帮助你在开发过程中处理用户登录、注销、权限检查等问题。
