FBV装饰器：
def auth(func): #装饰器函数
def inner(request, *args, **kwargs):
v = request.COOKIES.get(‘username‘)
if not v:
return redirect(‘/log/‘)
return func(request, *args, **kwargs)
return inner
使用方法：
在函数上加上@auth
CBV装饰器：
第一种方式：利用django自带的工具
def auth(func): #装饰器函数 对cookie进行认证
def inner(request, *args, **kwargs):
v = request.COOKIES.get(‘username‘)
if not v:
return redirect(‘/log/‘)
return func(request, *args, **kwargs)
return inner
from django import views
from django.utils.decorators import method_decorator #导入django自带的工具
class Auth(views.View):
@method_decorator(auth) #利用django自带工具 导入认证函数装饰器进行认证，灵活的放在任意需要认证的函数下面
def get(self, request):
v = request.COOKIES.get(‘username‘)
return render(request, ‘user_list.html‘, {‘current_user‘: v})
def post(self, request):
v = request.COOKIES.get(‘username‘)
return render(request, ‘user_list.html‘, {‘current_user‘: v})
第二种方式：
from django import views
from django.utils.decorators import method_decorator
class Auth(views.View):
@method_decorator(auth) #将装饰器放在父类方法上 这样该类下所有方法都被装饰上了装饰器，不用一一在写在函数上面
def dispatch(self, request, *args, **kwargs):
return super(Auth, self).dispatch(self, request, *args, **kwargs)
def get(self, request):
v = request.COOKIES.get(‘username‘)
return render(request, ‘user_list.html‘, {‘current_user‘: v})
def post(self, request):
v = request.COOKIES.get(‘username‘)
return render(request, ‘user_list.html‘, {‘current_user‘: v})
第三种方式：
from django import views
from django.utils.decorators import method_decorator
@method_decorator(auth, name=‘dispatch‘) #将装饰器直接装饰在类上面，在用name指定装饰在父类的diapatch方法上，这样也就实现了类里面所有方法的装饰效果
class Auth(views.View):
def get(self, request):
v = request.COOKIES.get(‘username‘)
return render(request, ‘user_list.html‘, {‘current_user‘: v})
def post(self, request):
v = request.COOKIES.get(‘username‘)
return render(request, ‘user_list.html‘, {‘current_user‘: v})
