Answer 1

在settings.py需要添加以下设置..

REST_FRAMEWORK = {
    'DEFAULT_RENDERER_CLASSES': (
        'rest_framework.renderers.JSONRenderer',
    ),
    'DEFAULT_PARSER_CLASSES': (
        'rest_framework.parsers.JSONParser',
    )
}

rest-framework的可浏览API是 json 。没必要写

？format = JSON

网址中的

只是用户界面

如果你卷曲api根：

curl -I http://drf-demo.herokuapp.com/api/universities/
HTTP/1.1 200 OK

@Devasish为所有视图提供默认设置，但是您也可以设置用于单个视图或视图集的渲染器，如以下the DRF doco中的示例所示：

APIView class-based views.

from django.contrib.auth.models import User
from rest_framework.renderers import JSONRenderer
from rest_framework.response import Response
from rest_framework.views import APIView

class UserCountView(APIView):
    """
    A view that returns the count of active users in JSON.
    """
    renderer_classes = [JSONRenderer]

    def get(self, request, format=None):
        user_count = User.objects.filter(active=True).count()
        content = {'user_count': user_count}
        return Response(content)

Django Rest Framework：默认情况下以JSON格式输出到浏览器
