快速入手-基于Django-rest-framework的自身组件权限认证（九）

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内容

authentication_classes = [SessionAuthentication]

permission_classes = [IsAuthenticated]

3、完整code

from django.shortcuts import render, HttpResponse
from rest_framework.response import Response
from rest_framework.decorators import action

from 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 serializers

from rest_framework.authentication import (
    BasicAuthentication,
    SessionAuthentication,
)
from rest_framework.permissions import IsAuthenticated, AllowAny


from .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 = LinkSerializer
    authentication_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]
