Django缓存分为Session和Cookie：Session为放在服务器端的缓存；Cookie为放在客户端（浏览器）的缓存。

Session一般用来保存登录会话；Cookie一般用来保存一些个性化的设置。

Session示例：

#!/usr/bin/env python#-*- encoding:utf-8 -*-from django.shortcuts import render,redirect# Create your views here.def login(request):    if request.method == 'POST':        user = request.POST.get('username',None)        pwd = request.POST.get('password',None)        if user == 'alex' and pwd == '123':   #登录成功            request.session['is_login'] = {
   'user':user}    #设置session，表示用户登录成功            return redirect('/login/index/')        else:  #登录失败            return render(request,'login/login.html',{
   'msg':'用户名或密码错误'})    return render(request,'login/login.html')def index(request):    user_dict = request.session.get('is_login',None)   #获取session，用于判断用户是否登录成功    if  user_dict:        return render(request, 'login/index.html',{
   'username':user_dict['user']})    else:        return redirect('/login/login')def logout(request):    del request.session['is_login']   #删除session    return redirect('/login/login')

 

Cookie示例：

def Page(request,page):    #第二种分页方式    counts = Host.objects.all().count()  # 获取数据总条数    #print request.POST    per_item = request.COOKIES.get('pager_num',5)  #从cookie中获取key为pager_num的值，获取不到则设置默认值为5    per_item = int(per_item)    #print 'per_item:',per_item    pages = PageInfo(page,counts,'/web/page/',per_item)    result = Host.objects.all()[pages.start_page:pages.end_page]  # 获取第page页内容    page_string = pages.page_string    #print 'page_string:',page_string    ctx = {        'data':result,        'count':counts,        'page_string':page_string,    }    response = render(request,'page.html',ctx)    #response.set_cookie(key='k1',value='v1')  #设置cookie    #request.COOKIES    #获取cookie    return response
