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

logout:

<!-- lang: python -->
from django.contrib.auth import logout
def logout_view(request):
    logout(request)
    # Redirect to a success page.

###若是是非登陸用戶使用logout註銷時，此函數不會提示任何錯誤或引起異常 ###調用logout時，當前登陸中的session會話數據(sessionid)會自動清除
