Django:如何在基于类的视图中将content-type标头设置为text/xml? [英] Django: how to set content-type header to text/xml within a class-based view?

问题描述

我正在尝试通过这种方式进行操作，但这是行不通的.

I'm trying to do it this way, but it doesn't work.

class MyView(View):

    def options(self, request, *args, **kwargs):
        """
        Handles responding to requests for the OPTIONS HTTP verb.
        """
        response = http.HttpResponse()
        if self.kwargs.has_key('xml'):
            response['Content-Type'] = 'text/xml; charset=utf-8'
        return response

推荐答案

我认为关键点是django.views.generic.base中的render_to_response，其代码是这样的:

I think the key point is render_to_response in django.views.generic.base , whose code is this:

def render_to_response(self, context, **response_kwargs):
    """
    Returns a response, using the `response_class` for this
    view, with a template rendered with the given context.

    If any keyword arguments are provided, they will be
    passed to the constructor of the response class.
    """
    response_kwargs.setdefault('content_type', self.content_type)   # key
    return self.response_class(
        request=self.request,
        template=self.get_template_names(),
        context=context,
        **response_kwargs
    )

对于您的情况，可能需要以下代码:

As for your case, May be you need this code:

class MyView(ListView):
    def get(self, request, *args, **kwargs):
        context = self.get_context_data()

        if self.kwargs.has_key('xml'):
            return self.render_to_response(context, content_type="text/xml; charset=utf-8")
        return self.render_to_response(context)
