可以在配置文件中配置全局默认的认证方案
REST_FRAMEWORK = {
'DEFAULT_AUTHENTICATION_CLASSES': (
'rest_framework.authentication.BasicAuthentication', # 基本认证
'rest_framework.authentication.SessionAuthentication', # session认证
)
}
也可以在每个视图中通过设置authentication_classess属性来设置
from rest_framework.authentication import SessionAuthentication, BasicAuthentication
from rest_framework.views import APIView
class ExampleView(APIView):
authentication_classes = (SessionAuthentication, BasicAuthentication)
...
认证失败会有两种可能的返回值:
权限控制可以限制用户对于视图的访问和对于具体数据对象的访问。
可以在配置文件中设置默认的权限管理类,如
REST_FRAMEWORK = {
'DEFAULT_PERMISSION_CLASSES': (
'rest_framework.permissions.IsAuthenticated',
)
}
如果未指明,则采用如下默认配置
'DEFAULT_PERMISSION_CLASSES': (
'rest_framework.permissions.AllowAny',
)
也可以在具体的视图中通过permission_classes属性来设置,如
from rest_framework.permissions import IsAuthenticated
from rest_framework.views import APIView
class ExampleView(APIView):
permission_classes = (IsAuthenticated,)
...
from rest_framework.authentication import SessionAuthentication
from rest_framework.permissions import IsAuthenticated
from rest_framework.generics import RetrieveAPIView
class BookDetailView(RetrieveAPIView):
queryset = BookInfo.objects.all()
serializer_class = BookInfoSerializer
authentication_classes = [SessionAuthentication]
permission_classes = [IsAuthenticated]
如需自定义权限,需继承rest_framework.permissions.BasePermission父类,并实现以下两个任何一个方法或全部
.has_permission(self, request, view)
是否可以访问视图, view表示当前视图对象
.has_object_permission(self, request, view, obj)
是否可以访问数据对象, view表示当前视图, obj为数据对象
例如:
class MyPermission(BasePermission):
def has_object_permission(self, request, view, obj):
"""控制对obj对象的访问权限,此案例决绝所有对对象的访问"""
return False
class BookInfoViewSet(ModelViewSet):
queryset = BookInfo.objects.all()
serializer_class = BookInfoSerializer
permission_classes = [IsAuthenticated, MyPermission]
可以对接口访问的频次进行限制,以减轻服务器压力。
可以在配置文件中,使用DEFAULT_THROTTLE_CLASSES
和 DEFAULT_THROTTLE_RATES
进行全局配置,
REST_FRAMEWORK = {
'DEFAULT_THROTTLE_CLASSES': (
'rest_framework.throttling.AnonRateThrottle',
'rest_framework.throttling.UserRateThrottle'
),
'DEFAULT_THROTTLE_RATES': {
'anon': '100/day',
'user': '1000/day'
}
}
DEFAULT_THROTTLE_RATES
可以使用 second
, minute
, hour
或day
来指明周期。
也可以在具体视图中通过throttle_classess属性来配置,如
from rest_framework.throttling import UserRateThrottle
from rest_framework.views import APIView
class ExampleView(APIView):
throttle_classes = (UserRateThrottle,)
...
1) AnonRateThrottle
限制所有匿名未认证用户,使用IP区分用户。
使用DEFAULT_THROTTLE_RATES['anon']
来设置频次
2)UserRateThrottle
限制认证用户,使用User id 来区分。
使用DEFAULT_THROTTLE_RATES['user']
来设置频次
3)ScopedRateThrottle
限制用户对于每个视图的访问频次,使用ip或user id。
例如:
class ContactListView(APIView):
throttle_scope = 'contacts'
...
class ContactDetailView(APIView):
throttle_scope = 'contacts'
...
class UploadView(APIView):
throttle_scope = 'uploads'
...
REST_FRAMEWORK = {
'DEFAULT_THROTTLE_CLASSES': (
'rest_framework.throttling.ScopedRateThrottle',
),
'DEFAULT_THROTTLE_RATES': {
'contacts': '1000/day',
'uploads': '20/day'
}
}
from rest_framework.authentication import SessionAuthentication
from rest_framework.permissions import IsAuthenticated
from rest_framework.generics import RetrieveAPIView
from rest_framework.throttling import UserRateThrottle
class BookDetailView(RetrieveAPIView):
queryset = BookInfo.objects.all()
serializer_class = BookInfoSerializer
authentication_classes = [SessionAuthentication]
permission_classes = [IsAuthenticated]
throttle_classes = (UserRateThrottle,)
