在api下面创建serializers.py文件

添加

from django.contrib.auth.models import User, Group
from rest_framework import serializers

class UserSerializer(serializers.HyperlinkedModelSerializer):
class Meta:
model = User
fields = ('url', 'username', 'email', 'groups')

class GroupSerializer(serializers.HyperlinkedModelSerializer):
class Meta:
model = Group
#显示的字段
fields = ('url', 'name')

在api的views里添加如下代码
from django.shortcuts import render

# Create your views here.
from django.contrib.auth.models import User, Group
from rest_framework import viewsets
from api.serializers import UserSerializer, GroupSerializer

class UserViewSet(viewsets.ModelViewSet):
"""
允许查看和编辑user 的 API endpoint
"""
queryset = User.objects.all()
serializer_class = UserSerializer

class GroupViewSet(viewsets.ModelViewSet):
"""
允许查看和编辑group的 API endpoint
"""
queryset = Group.objects.all()
serializer_class = GroupSerializer

在restful下面urls

from django.conf.urls import url,include
from django.contrib import admin

urlpatterns = [
url(r'^admin/', admin.site.urls),
#添加
url(r'^api/', include('api.urls')),
]

在api下面创建urls
添加

from django.conf.urls import patterns, url, include
from rest_framework import routers
from api import views

router = routers.DefaultRouter()
router.register(r'users', views.UserViewSet)
router.register(r'groups', views.GroupViewSet)

# Wire up our API using automatic URL routing.
# Additionally, we include login URLs for the browseable API.
urlpatterns = [
url(r'^', include(router.urls)),
#验证登录使用
url(r'auth',include('rest_framework.urls'))
]
