业务需求
优惠券活动，具体还是要根据自己的需求。以下是最近实现的优惠券活动，主要的业务需求：根据后端设置优惠券模板，用户类型设置，优惠券活动的开始与结束时间，最后生成不同的优惠券活动链接。
代码环境：
源码主要laravel5.8，一整个活动要贴的代码很多，下面主要贴核心代码，仅供参考。主要还是要根据自己的业务需求来实现功能吧。
以下是后端截图，做成模块化
前端需要做的设置与限制：
1 判断优惠券是否存在或者停用
2 判断活动开始时间与优惠券开始时间
接着领取活动优惠券，需要判断以下情况：
1 活动已结束
2 活动为开始时
3 活动为新用户领取，而领取的用户是老用户
4 活动为老用户领取，而领取的用户是新用户
5 优惠券是否领取完
6 已领取过优惠券提示
7 领取成功
