2、 创建一个项目
django-admin startproject djangorestdemo
3、 创建应用
cd djangorestdemo
python manage.py startapp rest
4、 在settings.py里配置
REST_FRAMEWORK={
'DEFAULT_PERMISSION_CLASSES': [
'rest_framework.permissions.DjangoModelPermissionsOrAnonReadOnly'
]
}
5、在djangorestdemo/urls.py编写相关代码
#编写序列化类
from django.contrib import admin
from django.urls import path
from django.conf.urls import url, include
from rest_framework import serializers,viewsets,routers
from django.contrib.auth.models import User
class UserSerializer(serializers.HyperlinkedModelSerializer):
class Meta:
model=User
fields=['url', 'username', 'email', 'is_staff']
#编写viewset视图集
class UserViewset(viewsets.ModelViewSet):
queryset = User.objects.all()
serializer_class = UserSerializer
#注册路由信息
router=routers.DefaultRouter()
router.register(r'users',UserViewset)
#urlpatterns里添加路由
urlpatterns = [
url('admin/', admin.site.urls),
url(r'^',include(router.urls)),
url(r'^api-auth/', include('rest_framework.urls', namespace='rest_framework'))
]
6、运行：python manage.py runserver
7、浏览器上访问接口
