有没有更好的方法从Django的"as_view“机制中获取CBV实例？

def get_cbv_instance(view_class):
    def decorator(view_func):
        def wrapper(request, *args, **kwargs):
            instance = view_class()
            # 在这里可以访问CBV实例并进行操作
            return view_func(request, instance, *args, **kwargs)
        return wrapper
    return decorator

@get_cbv_instance(MyView)
def my_view(request, instance):
    # 可以访问CBV实例并进行操作
    return instance.get(request)

class CBVInstanceMiddleware:
    def __init__(self, get_response):
        self.get_response = get_response

    def __call__(self, request):
        response = self.get_response(request)
        view_func = getattr(request, 'view_func', None)
        if view_func:
            instance = getattr(view_func, 'view_class', None)()
            # 在这里可以访问CBV实例并进行操作
        return response

def my_view(request):
    request.view_func = MyView.as_view()
    return HttpResponse('Hello, World!')
