        #in here set cookie,but can get the response 
        #response.set_cookie("success","success")

        return context

回答1:

You cannot set_cookie on a request, only on response, but burhan-khalid was going in the correct direction. get_context_data only returns a dictionary, so you cannot access the response there. You have to access it either in dispatch, or with a TemplateView, in render_to_response. Here is an example:

class MyView(TemplateView):
    def render_to_response(self, context, **response_kwargs):
        response = super(MyView, self).render_to_response(context, **response_kwargs)
        response.set_cookie("success","success")
        return response

I would suggest you shouldn't do all your processing code in get_context_data. You may need to refactor to get the cookie you want set in render_to_response.
