首先确保你有 SessionMiddleware 和 AuthenticationMiddleware 添加到您的 MIDDLEWARE_CLASSES 设置中。

First make sure you have SessionMiddleware and AuthenticationMiddleware middlewares added to your MIDDLEWARE_CLASSES setting.

当前用户在请求对象中，您可以通过以下方式获取它：

The current user is in request object, you can get it by:

def sample_view(request):
    current_user = request.user
    print current_user.id

request.user 会给你表示当前登录的用户的用户对象。如果用户当前未登录，则 request.user 将被设置为 AnonymousUser 的实例。你可以用 is_authenticated（）告诉他们，如下所示：

request.user will give you a User object representing the currently logged-in user. If a user isn't currently logged in, request.user will be set to an instance of AnonymousUser. You can tell them apart with is_authenticated(), like so:

if request.user.is_authenticated():
    # Do something for authenticated users.
else:
    # Do something for anonymous users.
