1、在对应的视图函数里增加认证（局部起作用，不全局生效）
导入类：
from rest_framework.authentication import (
BasicAuthentication,
SessionAuthentication,
)
from rest_framework.permissions import IsAuthenticated, AllowAny
2、基于第八节内容增加以下权限设置内容
#定义认证类型
authentication_classes = [SessionAuthentication]
#定义权限限制
permission_classes = [IsAuthenticated]
备注说明：
AllowAny 允许所有用户，默认权限
IsAuthenticated 仅通过登录认证的用户
IsAdminUser 仅管理员用户
IsAuthenticatedOrReadOnly 已经登录认证的用户可以对数据进行CRUD操作，
没有登录认证的用户，只能查看数据
3、完整code
from django.shortcuts import render, HttpResponse
from rest_framework.response import Response
from rest_framework.decorators import actionfrom rest_framework.viewsets import GenericViewSet
from rest_framework.mixins import (ListModelMixin,CreateModelMixin,RetrieveModelMixin,UpdateModelMixin,DestroyModelMixin,
)
from rest_framework.viewsets import ModelViewSet
from rest_framework import serializersfrom rest_framework.authentication import (BasicAuthentication,SessionAuthentication,
)
from rest_framework.permissions import IsAuthenticated, AllowAnyfrom .models import *
from api.serializer import *# 这种写法实现所有的增删改查，不能够单独进行操作
# class Linkapi(ModelViewSet):
# 不仅可以实现所有的增删改查，而且可以单独也可以全部包含增删改查
class Linkapi(GenericViewSet,ListModelMixin,CreateModelMixin,RetrieveModelMixin,UpdateModelMixin,DestroyModelMixin,
):queryset = Link.objects.all()serializer_class = LinkSerializerauthentication_classes = [SessionAuthentication]permission_classes = [IsAuthenticated]# 在原有的二级路由中自定义添加三级路由路径# 访问路径/api/linkapi/{pk}/login/@action(methods=["get", "POST"],detail=True,url_path="login",)def login(self, request, pk):queryset = self.get_queryset()serializer = self.get_serializer(queryset, many=True)return Response(serializer.data)# detail为false表示路径名格式应该为/api/linkapi/get_new_5/@action(methods=["get",],detail=False,)def get_new_2(self, request):obj = Link.objects.all().filter()[:2]serializer = self.get_serializer(instance=obj, many=True)return Response(serializer.data)
4、测试
5、仅允许查询，其他方式请求未授权不能访问
导入包
from rest_framework.permissions import (
IsAuthenticated,
AllowAny,
IsAuthenticatedOrReadOnly,
)
修改视图类内容
# IsAuthenticated 授权登录后可以访问
# IsAuthenticatedOrReadOnly 只允许查询
permission_classes = [IsAuthenticatedOrReadOnly]
