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 innerfrom 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 viewsfrom django.utils.decorators import method_decoratorclass 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 viewsfrom 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})
