django如何获取基于类的视图中的Response [英] django how to get Response in class based view

问题描述

现在我有一个基于类的视图。并且我想在这个视图中设置cookie，但我可以得到响应，但响应返回的get methond .so我不能设置cookie到response.so如何获取Response在基于类的视图

now i have a class-based view. and i want to set cookie in this view,but i can get the response,but the response is returned in the get methond .so i can not set the cookie to response.so how to get Response in class based view

 class MyView(TemplateView):
    def get_context_data(self, **kwargs):
        context = super(UBaseTemplateView, self).get_context_data(**kwargs)

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

        return context

推荐答案

code>请求，仅在响应，但burhan-khalid正确的方向。 get_context_data 只返回一个字典，因此您无法访问该响应。您必须在 dispatch 或 TemplateView 中在 render_to_response 。这里是一个例子：

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

我建议你不要在 get_context_data 。您可能需要重构以获取您在 render_to_response 中设置的Cookie。

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.
