django rest-farme-work 的使用(1)

Django REST框架是一个用于构建Web API的强大且灵活的工具包

您可能想要使用REST框架的一些缘由:

• 可浏览性
• 身份认证
• 支持ORM和非ORM的序列化
• 良好的文档支持

安装初步

pip install djangorestframework
pip install markdown       # Markdown support for the browsable API.
pip install django-filter  # Filtering support

可选包：

文件配置

在配置文件setting 中添加 APP以下图

INSTALLED_APPS = (
    ...
    'rest_framework',
)

在url 中添加路由以下

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

example (例子)

咱们来看看使用REST框架构建简单模型支持的API的一个简单例子。
咱们将建立一个读写API来访问咱们项目用户的信息。
REST框架API的任何全局设置都保存在一个名为的配置字典中REST_FRAMEWORK。首先将如下内容添加到您的settings.py模块中：

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'
    ]
}

咱们准备好如今建立咱们的API。这是咱们项目的根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'))
]
