# ↑上login 函数与(http://127.0.0.1:8000/order,访问时,若没有登录的情况下,会自动跳转到/login/的页面中,只有登录了才可以看到 http://127.0.0.1:8000/order/的这个页面中(没有跳转到/login/的页面中) )order函数下↓
# 此是为了判断cookie是否存在,存在的话便会看到order的页面中
# 基于cookie 写了登录验证
# def order(request):
# is_login = request.COOKIES.get('is_login') # 获取cookie
# # 判断是否有cookie,获取到的话会看到"我是订单页面,我得登录才能看",获取不到会返回到/login/页面中
# if is_login:
# return HttpResponse('我是订单页面,我得登录才能看')

# return redirect('/login/')

# is_login = request.COOKIES.get('is_login') # 获取cookie
# if is_login:
