权限

DRF提供如下几种常见权限：

IsAuthenticated, 认证通过

IsAdminUser, 管理员权限

IsAuthenticatedOrReadOnly, 登录用户增删改 非登录用户只能查询

AllowAny，无需认证（默认）

在rest_framework的APIView基础类中，对认证与权限做了更高级的封装，如下：

class APIView(View):# The following policies may be set at either globally, or per-view.authentication_classes = api_settings.DEFAULT_AUTHENTICATION_CLASSESpermission_classes = api_settings.DEFAULT_PERMISSION_CLASSES

如果需要单独设置

from django.conf import settings
from rest_framework.authtoken.models import Token
from rest_framework.decorators import api_view,authentication_classes,permission_classes
from rest_framework.permissions import IsAuthenticated
from rest_framework.response import Response
from rest_framework import status,generics,viewsets
#from rest_framework import permissions
from rest_framework.authentication import BasicAuthentication,SessionAuthentication,TokenAuthentication
from .models import Course
from .serializers import CourseSerializer
from rest_framework.views import APIView

fbv 方式

##函数式编程
@api_view(['GET','POST'])
@authentication_classes((BasicAuthentication,SessionAuthentication,TokenAuthentication))
@permission_classes((IsAuthenticated,))
def course_list(request):

cbv  gcbv viewsets 方式

# 类视图 Class Based View
class CourseList(APIView):authentication_classes = 
(BasicAuthentication,SessionAuthentication,TokenAuthentication)
permission_classes = ((IsAuthenticated))def get(self,request):print(self.request.user,self.request.auth)

自定义权限

 新建文件permissions.py

from rest_framework import permissionsclass IsOwnerReadOnly(permissions.BasePermission):#只允许对象的所有者能编辑def has_object_permission(self, request, view, obj):"""所有的request 都有读权限:param request::param view::param obj::return:"""#if request.method in ("GET","HEAD","OPTIONS"):if request.method in permissions.SAFE_METHODS:return True#对象的所有这才有写权限return obj.teacher == request.user   #gcbv

加入到views.py 文件

class GCourseDetail(generics.RetrieveUpdateDestroyAPIView):queryset = Course.objects.all()serializer_class = CourseSerializerpermission_classes = (IsAuthenticated,IsOwnerReadOnly)# DRF 视图集 viewsets
class CourseViewSet(viewsets.ModelViewSet):queryset = Course.objects.all()serializer_class = CourseSerializerpermission_classes = (IsAuthenticated, IsOwnerReadOnly)def perform_create(self, serializer):serializer.save(teacher= self.request.user)
