网站需要登陆才提供服务，因此需要在未登录时跳转到登陆页面．
本网站在登陆之后会存username的cookie, 因此通过检测该cookie是否存在判断用户是否登陆
自定义的middleware写在login下
login目录结构如下

setting中增加middleware最后一条
MIDDLEWARE_CLASSES = [
'django.middleware.security.SecurityMiddleware',
'django.contrib.sessions.middleware.SessionMiddleware',
'django.middleware.common.CommonMiddleware',
# 'django.middleware.csrf.CsrfViewMiddleware',
'django.contrib.auth.middleware.AuthenticationMiddleware',
'django.contrib.auth.middleware.SessionAuthenticationMiddleware',
'django.contrib.messages.middleware.MessageMiddleware',
'django.middleware.clickjacking.XFrameOptionsMiddleware',
'login.LoginMiddleware.QtsAuthenticationMiddleware',
]
装饰器代码
# coding=utf-8
from django.shortcuts import render,HttpResponse,redirect,HttpResponseRedirect
try:
from django.utils.deprecation import MiddlewareMixin # Django 1.10.x
except ImportError:
MiddlewareMixin = object # Django 1.4.x - Django 1.9.x
class QtsAuthenticationMiddleware(MiddlewareMixin):
def process_request(self, request):
if request.path != '/login/':
if request.COOKIES.get('username',None):
pass
else:
return HttpResponseRedirect('/login/')
这样就可以实现未登录时跳转到登陆页面
