CBV装饰校验的三种方式session

代码如下：

from django.shortcuts import render,HttpResponse,redirect
from django.views import View
# Create your views here.


def login(request):
    if request.method == 'POST':
        username = request.POST.get('name')
        password = request.POST.get('password')
        if username == 'jason' and password == '123':
            request.session['name'] = 'jason'
            return redirect('/home')
    return render(request,'login.html')


# 要用装饰器需要导的模块
from functools import wraps
from django.utils.decorators import method_decorator
def login_auth(func):
    @wraps(func)
    def inner(request,*args,**kwargs):
        if request.session.get('name'):
            return func(*args,**kwargs)
        return redirect('/login')
    return inner

#第二种 name参数必须指定
@method_decorator(login_auth,name='get')
class MyHome(View):
    #第三种  只要是在该类中定义的方法都会被指定
    @method_decorator(login_auth)
    def dispatch(self, request, *args, **kwargs):
        super().dispatch(request,*args,**kwargs)
    # 第一种
    @method_decorator(login_auth)
    def get(self,request):
        return HttpResponse('get')

    def post(self,request):
        return HttpResponse('home')
