我一直在尝试添加注册/登录/注销功能。用户注册似乎工作正常，因为创建的用户显示在Django admin中，并显示在数据库中。然而，每当我尝试实现登录功能时，它都不会起作用。我想我已经把问题缩小到
authenticate（）

我已经尝试了一切，无论我做什么，
authenticate（）
函数总是返回
None
。我提供的用户名和密码显然已被存储，但它似乎没有正确获取密码，因为在
login\u user
视图中打印出
raw\u password=form.cleaned\u data.get（'password1'）

如何使登录功能正常工作

在url.py中

urlpatterns = [
    path('register', views.register_user, name='register'),
    path('login', views.login_user, name='login'),
    path('logout', views.logout_user, name='logout'),
]

def register_user(request):
    if request.method == 'POST':
        form = UserCreationForm(request.POST)

        if form.is_valid():
            form.save()
            username = form.cleaned_data.get('username')
            raw_password = form.cleaned_data.get('password1')
            user = authenticate(username=username, password=raw_password)
            print(f'User is: {user}')
            login(request, user)
            return redirect('/')

    else:

    }
    return render(request, 'register.html', context)

def login_user(request):
    if request.method == 'POST':
        form = AuthenticationForm(request=request, data=request.POST)
        if form.is_valid():
            username = form.cleaned_data.get('username')
            raw_password = form.cleaned_data.get('password1')
            user = authenticate(username=username, password=raw_password)
            print(f'User is: {user}')
            print(f'username is: {username}')
            print(f'password is: {raw_password}')

登录

register\u user
和
logout\u user
视图似乎工作正常。在
register\u user
视图中，我将其设置为在注册后自动记录用户。奇怪的是，在这种情况下登录是有效的。但是，由于上述原因，登录不适用于登录用户视图。

raw\u password=form.cleaned\u data.get（'password1'）
此处必须获取密码本身，而不是密码1
