1.首先安装Django-Rest-Framework

pip3 install djangorestframework
pip3 install markdown Markdown为可视化 API 提供了支持
pip3 install django-filter

2.使用pycharm创建一个工程和一个app

工程名：restful

app名：api

数据库默认使用sqlite3

3.配置rest_framework

打开settings文件        INSTALLED_APPS = [
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',
'api',
'rest_framework' #新增
]添加
REST_FRAMEWORK = {'DEFAULT_PERMISSION_CLASSES': ('rest_framework.permissions.IsAdminUser',),'PAGINATE_BY': 10
}

4.同步数据库

python manage.py makemigrations
python manage.py migrate

5.序列化

在api下面创建serializers.py文件添加from django.contrib.auth.models import User, Group
from rest_framework import serializersclass UserSerializer(serializers.HyperlinkedModelSerializer):class Meta:model = Userfields = ('url', 'username', 'email', 'groups')class GroupSerializer(serializers.HyperlinkedModelSerializer):class Meta:model = Group#显示的字段fields = ('url', 'name')

6.添加视图

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, GroupSerializerclass UserViewSet(viewsets.ModelViewSet):"""允许查看和编辑user 的 API endpoint"""queryset = User.objects.all()serializer_class = UserSerializerclass GroupViewSet(viewsets.ModelViewSet):"""允许查看和编辑group的 API endpoint"""queryset = Group.objects.all()serializer_class = GroupSerializer

7.设置url

在restful下面urlsfrom django.conf.urls import url,include
from django.contrib import adminurlpatterns = [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 viewsrouter = 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'))]

8.启动访问
