Javascript 如何在基于Django类的视图中按mime类型区分响应？

在基于类的视图中，我可以为

GET

或

POST

定义方法。我可以为不同mime类型的响应定义特殊的方法吗

用例是——即使关闭JS，也要使AJAX站点可用

import json

from django.http import HttpResponse
from django.views.generic.edit import CreateView
from myapp.models import Author

class AjaxableResponseMixin(object):
    """
    Mixin to add AJAX support to a form.
    Must be used with an object-based FormView (e.g. CreateView)
    """
    def render_to_json_response(self, context, **response_kwargs):
        data = json.dumps(context)
        response_kwargs['content_type'] = 'application/json'
        return HttpResponse(data, **response_kwargs)

    def form_invalid(self, form):
        response = super(AjaxableResponseMixin, self).form_invalid(form)
        if self.request.is_ajax():
            return self.render_to_json_response(form.errors, status=400)
        else:
            return response

    def form_valid(self, form):
        # We make sure to call the parent's form_valid() method because
        # it might do some processing (in the case of CreateView, it will
        # call form.save() for example).
        response = super(AjaxableResponseMixin, self).form_valid(form)
        if self.request.is_ajax():
            data = {
                'pk': self.object.pk,
            }
            return self.render_to_json_response(data)
        else:
            return response

class AuthorCreate(AjaxableResponseMixin, CreateView):
    model = Author
    fields = ['name']

请从文档中查看此示例：

有两种情况：表格是否有效。

从这里我们有两种情况：如果请求是否基于AJAX（request.is_AJAX）

您可以检查

request.META的
Accept
标题，以决定返回哪种响应格式，并使用适当的序列化程序将“一般响应”序列化为适当的格式。这和我的想法很相似。
