Rest Framework

官网

步骤：

安装：

sudo pip install djangorestframework
sudo pip install markdown       
sudo pip install django-filter   

或者直接从github克隆下来：

git clone git@github.com:encode/django-rest-framework.git

settings中配置：

INSTALLED_APPS = (
    ...
    'rest_framework',  
)

urls中配置

urlpatterns = [ 
    ...
    url(r'^api-auth/', include('rest_framework.urls', namespace='rest_framework'))
]

Note that the URL path can be whatever you want, but you must include 'rest_framework.urls' with the 'rest_framework' namespace. You may leave out the namespace in Django 1.9+, and REST framework will set it for you.

示例：

在settings.py中：

REST_FRAMEWORK = {
    # Use Django's standard `django.contrib.auth` permissions,
    # or allow read-only access for unauthenticated users.
    'DEFAULT_PERMISSION_CLASSES': [
        'rest_framework.permissions.DjangoModelPermissionsOrAnonReadOnly'
    ]
}

不要忘记添加rest_framework在你的INSTALLED_APPS中。
我们就最好了写API的准备工作，下面是根 urls.py模块。

from django.conf.urls import url, include
from django.contrib.auth.models import User
from rest_framework import routers, serializers, viewsets

# Serializers define the API representation.
class UserSerializer(serializers.HyperlinkedModelSerializer):
    class Meta:
        model = User
        fields = ('url', 'username', 'email', 'is_staff')

# ViewSets define the view behavior.
class UserViewSet(viewsets.ModelViewSet):
    queryset = User.objects.all()
    serializer_class = UserSerializer

# Routers provide an easy way of automatically determining the URL conf.
router = routers.DefaultRouter()
router.register(r'users', UserViewSet)

# Wire up our API using automatic URL routing.
# Additionally, we include login URLs for the browsable API.
urlpatterns = [
    url(r'^', include(router.urls)),
    url(r'^api-auth/', include('rest_framework.urls', namespace='rest_framework'))
]

现在你就可以在浏览器中http://127.0.0.1:8000/，查看你的users API。
