python - 405 "Method POST is not allowed" in Django REST framework

I am new in Django REST framework. Can someone explain why I get such error, if I make a POST request to '/api/index/'

405 Method Not Allowed
{"detail":"Method "POST" not allowed."}

My code is following:

# views.py
class ApiIndexView(APIView):
    permission_classes = (permissions.AllowAny,)

    def post(self, request, format=None):
        return Response("ok")

# urls.py
urlpatterns = [
    url(r'^api/index/$', views.ApiIndexView.as_view()),
]

# settings.py
REST_FRAMEWORK = {
    'DEFAULT_PERMISSION_CLASSES': (
        'rest_framework.permissions.DjangoModelPermissions',
    ),
    'DEFAULT_AUTHENTICATION_CLASSES': (
        'rest_framework.authentication.SessionAuthentication',
        'rest_framework.authentication.TokenAuthentication',
    )
}

But if I add <pk> into my pattern, everything works fine:

# views.py
class ApiIndexView(APIView):
    permission_classes = (permissions.AllowAny,)

    def post(self, request, pk, format=None):
        return Response("ok")

# urls.py
urlpatterns = [
    url(r'^api/index/(?P<pk>d+)/$', views.ApiIndexView.as_view()),
]

I am completely confused. Why it's necessary to use <pk> and is there a way to avoid the use of this parameter in the URL pattern?

You need to change just:

# views.py
class ApiIndexView(UpdateView):
    permission_classes = (permissions.AllowAny,)

    def post(self, request, format=None):
        return Response("ok")
