使用django实现rest_framework序列化 api

      django使用rest_framework 实现web的api接口。
     安装pip install djangorestframework
     在settings配置文件中设置,加入app和权限设置
    

INSTALLED_APPS = [

    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'rest_framework',
    'quick',
    'blog',
]

REST_FRAMEWORK = {

    'DEFAULT_PERMISSION_CLASSES':(
        #only allow admin user
        #'rest_framework.permissions.IsAdminUser',
        #use django's standard users permissions,
        # or allow read-only access for unauthenticated users
        #'rest_framework.permissions.DjangoModelPermissionsOrAnonReadOnly',
    ),

    'PAGE_SIZE':10
}

     首先实现数据库，models.py
     

class His_Comm(models.Model):
    his_id = models.CharField(max_length=10)
    host_ip = models.GenericIPAddressField(default='')
    his_user = models.CharField(max_length=10)
    his_time = models.CharField(max_length=20)
    his_command = models.CharField(max_length=200)

    def __str__(self):
        return self.his_id

      
       设置数据库接口序列化
  serializers.py
  

from rest_framework import serializers
from quick.models import His_Comm

class HisSerializser(serializers.HyperlinkedModelSerializer):
    class Meta:
        model = His_Comm
        fields = ('his_id','host_ip','his_user','his_command','his_time')

    设置展示序列化数据  
    views.py

from rest_framework import viewsets
from serializers import
UserSerializer,GroupSerializer,HisSerializser
from quick.models import His_Comm

class HisSet(viewsets.ModelViewSet):
    queryset = His_Comm.objects.all()
    serializer_class = HisSerializser

urls.py设置路由  
    

from rest_framework import routers,urls



router = routers.DefaultRouter()
router.register(r'hist',views.HisSet)

urlpatterns = [
    url(r'^api/', include(router.urls)),        #接口api
    url(r'^api-auth/',include('rest_framework.urls',namespace='rest_framework')),    #接口账户认证
]

实现了hist的接口实现，当使用post方法时，需要在settings. REST_FRAMEWORK.DEFAULT_PERMISSION_CLASSES 设置权限。是否允许匿名用户实现post数据库请求。
