购物车：
商品信息- 数量、单价、名称
用户信息- 帐号、密码、余额
用户可充值
购物历史信息
允许用户多次购买，每次可购买多件
余额不足时进行提醒
用户退出时 ，输出档次购物信息
用户下次登陆时可查看购物历史
商品列表分级显示

HAproxy配置文件操作：
根据用户输入输出对应的backend下的server信息
可添加backend 和sever信息
可修改backend 和sever信息
可删除backend 和sever信息
操作配置文件前进行备份 6 添加server信息时，如果ip已经存在则修改;如果backend不存在则创建；若信息与已有信息重复则不操作
配置文件 参考 http://www.cnblogs.com/alex3714/articles/5717620.html
