業(yè)務(wù)需求
優(yōu)惠券活動(dòng)，具體還是要根據(jù)自己的需求。以下是最近實(shí)現(xiàn)的優(yōu)惠券活動(dòng)，主要的業(yè)務(wù)需求：根據(jù)后端設(shè)置優(yōu)惠券模板，用戶類型設(shè)置，優(yōu)惠券活動(dòng)的開始與結(jié)束時(shí)間，最后生成不同的優(yōu)惠券活動(dòng)鏈接。
代碼環(huán)境：
源碼主要laravel5.8，一整個(gè)活動(dòng)要貼的代碼很多，下面主要貼核心代碼，僅供參考。主要還是要根據(jù)自己的業(yè)務(wù)需求來實(shí)現(xiàn)功能吧。
以下是后端截圖，做成模塊化
前端需要做的設(shè)置與限制：
1 判斷優(yōu)惠券是否存在或者停用
2 判斷活動(dòng)開始時(shí)間與優(yōu)惠券開始時(shí)間
接著領(lǐng)取活動(dòng)優(yōu)惠券，需要判斷以下情況：
1 活動(dòng)已結(jié)束
2 活動(dòng)為開始時(shí)
3 活動(dòng)為新用戶領(lǐng)取，而領(lǐng)取的用戶是老用戶
4 活動(dòng)為老用戶領(lǐng)取，而領(lǐng)取的用戶是新用戶
5 優(yōu)惠券是否領(lǐng)取完
6 已領(lǐng)取過優(yōu)惠券提示
7 領(lǐng)取成功
下面核心代碼實(shí)現(xiàn)
