          username = request.COOKIES['username']
      else:

  def login_check(request):
      username = request.POST.get("username");
      password = request.POST.get("password");
      remember = request.POST.get('remember');
  
      if username == 'smart' and password =='123':
          # 用户名密码正确 ， 跳转到登陆成功页面
          response = redirect("/index")
          #判断是否记住用户名
          if remember =="on":
              #设置cookie username *过期时间为1周
             response.set_cookie('username',username,max_age=7*24*3600)
