微信小程序优惠劵功能（包含用户需求，axure原型设计，数据库设计，后台功能，微信小程序功能）

1.用户需求

优惠券功能有：
1.后台可以设置优惠券和查看已发出优惠券的状态
2.平台自动给新用户发放优惠劵，或者手动给某些用户发放优惠券
3.用户在小程序中手动领取优惠券
4.用户中心新增“优惠券”模块，查看所有优惠券
5.下单时使用优惠券

2.axure原型设计

原型设计生成的html页面，下载地址：https://download.csdn.net/download/jlq_diligence/19652279
下载后，使用ie浏览器打开，打开后的html文件目录结构如下：

3.数据库设计

优惠劵2张表的表结构如下：

CREATE TABLE `coupon_rules` (
  `id` int(11) unsigned NOT NULL AUTO_INCREMENT COMMENT '优惠券主键',
  `gmt_create` datetime NOT NULL COMMENT '优惠券创建时间',
  `gmt_modified` datetime DEFAULT NULL COMMENT '优惠券修改时间',

  `duration` int(11) DEFAULT '30' COMMENT '领取后优惠券的有效天数',
  PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=18 DEFAULT CHARSET=utf8mb4;


CREATE TABLE `coupon_info` (
  `id` int(11) unsigned NOT NULL AUTO_INCREMENT COMMENT '优惠券主键',
  `rules_id` int(11) NOT NULL COMMENT '关联优惠券规则主键id',
  `grant_time` datetime DEFAULT NULL COMMENT '优惠券发放时间',

  `use_conditions_content` decimal(10,2) DEFAULT NULL COMMENT '使用条件补充内容',
  `from_id` int(11) DEFAULT NULL COMMENT '发放来源(存储完工的订单id或注册的商家id等等)',
  `from_remark` varchar(255) CHARACTER SET utf8 DEFAULT NULL COMMENT '发放备注',
  `gmt_create` datetime NOT NULL COMMENT '优惠券创建时间',
  `gmt_modified` datetime DEFAULT NULL COMMENT '优惠券修改时间',
  PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=52 DEFAULT CHARSET=utf8mb4;

4.后台优惠劵功能实现
