如何在我现有的视图中使用Django密码验证？

from django.contrib.auth import authenticate, login

def my_view(request):
    if request.method == 'POST':
        username = request.POST.get('username')
        password = request.POST.get('password')
        # 其他处理逻辑...

def my_view(request):
    if request.method == 'POST':
        username = request.POST.get('username')
        password = request.POST.get('password')
        
        user = authenticate(request, username=username, password=password)
        if user is not None:
            # 用户验证成功，执行登录操作
            login(request, user)
            # 其他处理逻辑...
        else:
            # 用户验证失败，处理错误逻辑...

def my_view(request):
    if request.method == 'POST':
        username = request.POST.get('username')
        password = request.POST.get('password')
        
        user = authenticate(request, username=username, password=password)
        if user is not None:
            login(request, user)
            # 用户验证成功，执行其他处理逻辑...
        else:
            # 用户验证失败，处理错误逻辑...
