django的rest

官方文档

https://www.django-rest-framework.org/#

安装

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

配置

Add ‘rest_framework’ to your INSTALLED_APPS setting.

INSTALLED_APPS = [ ... 'rest_framework', ]

If you’re intending to use the browsable API you’ll probably also want to add REST framework’s login and logout views. Add the following to your root urls.py file.

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

例子

REST框架API的任何全局设置都保存在一个名为REST_FRAMEWORK的配置字典中。首先在settings.py模块中添加以下内容:

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' ] }

现在我们已经准备好创建API了。这是我们项目的根url .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')) ]

从这里我们可以看到，视图和urls都被写道同一个文件里面了。这是官方为了给我们演示方便而采取的方式，实际开发会采用新建serializers的方式。请看我下一篇博文： https://blog.csdn.net/weixin_43431593/article/details/107142415
