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

下面核心代码实现

/** * Function:优惠券领取处理 * Author:cyw0413 * @param $params * @return array * @throws \Exception */public function doCoupon($params){ $activity_id = $params['activity_id']; if(!$params){ throw new \Exception("参数错误！"); } $preg_phone = '/^1[34578]\d{9}$/ims'; $is_mobile = preg_match ($preg_phone, $params['mobile']); if ($is_mobile == 0) { throw new \Exception("手机号码不正确！"); } //隐藏手机号码中间4位 $str_mobile = substr_replace($params['mobile'],'****',3,4); $activity = $this->find($activity_id); if(empty($activity)){ throw new \Exception("不存在此活动"); } $activity_link = $activity->activityLink->where('coupon_status',0); //只选择不停用的优惠券 if(count($activity_link) <= 0){ throw new \Exception("优惠券不存在或者已经停用"); }else{ //查找注册用户ID $showUser = $this->showUser($params['mobile']); //主要是过滤掉领取优惠券为0的，用laravel的同学注意看看 $detail = $activity_link->each(function($item,$index) use ($showUser) { $diffCouponQuantity = $this->diffCouponQuantity($item['config_id'],$item['quantity'],$item['activity_id'],$showUser); $item->title = $this->getCouponName($item['config_id'])['name']; $item->number = $item['quantity']; $item->msg = $diffCouponQuantity ['msg']; $item->diff = $diffCouponQuantity ['diff']; $item->code = $diffCouponQuantity ['code']; })->toArray(); if(count($detail) == 1){ foreach($detail as $val){ if($val['diff'] == 1 && $val['code'] == '400'){ throw new \Exception($detail[0]['msg']); } } } $collection_coupon = collect($detail); $collection_coupon = $collection_coupon->where('diff', '<=' ,'0'); //去除优惠券剩余数量为0，或者领取优惠券数量-剩余数量 > 0 } //判断活动开始时间与优惠券开始时间 $act_coupon = ActivityCouponBaseModel::where('activity_id',$activity['activity_id'])->first(); $check_time = $this-> checkCouponTime($act_coupon['start_time'],$activity_link); if($check_time == 'error'){ throw new \Exception("优惠券领取时间未开始,暂不可领取"); } //领取活动有以下几种情况 //1: 活动已结束 if($activity['end_time'] < date("Y-m-d H:i:s") || $activity['status'] == 1){ $result = [ 'code' => 1, ]; return $result; } //6 活动为开始时 if($activity['start_time'] > date("Y-m-d H:i:s") || $activity['status'] == 1){ $result = [ 'code' => 6, ]; return $result; } $checkUser = $this->haveUser($params['mobile']); //检查是新用户，还是老用户 根据自己的业务需求做，这个方法就不贴了 //2: 活动为新用户领取，而领取的用户是老用户 if($activity['user_type'] == 1 && !empty($checkUser)){ $result = [ 'code' => 2, ]; return $result; } //3：活动为老用户领取，而领取的用户是新用户 if($activity['user_type']==2 && empty($checkUser)){ $result = [ 'code' => 3, ]; return $result; } //4：优惠券是否领取完 $coupon = $this->getCouponExpire($collection_coupon,$params['mobile']); //这里提示有一个优惠券列表，根据自己的业务需求做，这个方法就不贴了 //return $coupon; if($coupon == 1){ $result = [ 'code' => 4, ]; return $result; } //5：已领取过优惠券提示 $userCoupon = ''; $userRate = ''; if(!empty($checkUser)){ //user存在则为老用户，再检查是否领取过 $userCoupon = $this->getUserCoupon($collection_coupon,$checkUser['user_id']); $userRate = $this->getUserCouponRate($checkUser['user_id'],$activity['activity_id']); }else{ //新用户，检查是否注册过 $var_user = UserBaseModel::where('user_name',$params['mobile'])->first(); if(!empty($var_user)){ $userCoupon = $this->getUserCoupon($collection_coupon,$var_user['user_id']); $userRate = $this->getUserCouponRate($var_user['user_id'],$activity['activity_id']); } } //return $userRate; if($userCoupon == 1){ $result = [ 'code' => 5, 'phone'=> $str_mobile, 'coupon' => $userRate, 'is_get' => false, ]; return $result; } //5：领取成功 //如果活动规定是新老用户0，新用户1，老用户2 $getCouponSuccess = $this->getCouponSuccess($activity['user_type'],$checkUser,$collection_coupon,$params['mobile']); //return $getCouponSuccess; if($getCouponSuccess['status'] == 200){ $result = [ 'code' => 5, 'phone'=> $str_mobile, 'coupon' => $getCouponSuccess['result'][0], 'is_get' => true, ]; return $result; }}

用户领取优惠券并发放优惠券

/** * Function:用户领取活动 * Author:cyw0413 * @param $user_type */public function getCouponSuccess($user_type,$user,$coupon,$mobile){ if(count($coupon) > 0){ switch ($user_type){ case 1: //新用户领取，如果从来没注册过就要新增用户 $res = $this->addUser($mobile,$coupon); return [ 'result' => $res, 'status' => 200 ]; break; case 2: //老用户领取 $res = $this->insertUserCoupon($user,$coupon); return [ 'result' => $res, 'status' => 200 ]; break; default: //新老用户领取,判断是新用户还是老用户,这里的$user是有无配送单，有则为老用户； if(empty($user)){ $res = $this->addUser($mobile,$coupon); }else{ $res = $this->insertUserCoupon($user,$coupon); //老用户，直接发放优惠券 } return [ 'result' => $res, 'status' => 200 ]; break; } }else{ throw new \Exception("优惠券不存在或者已经停用"); }}

领取成功，则发放优惠券

/** * Function:发放优惠券 * Author:cyw0413 * @param $user * @param $coupon */public function insertUserCoupon($user,$coupon){ $relate = []; foreach($coupon as $item){ $res = CouponConfigSendBaseModel::where([ 'config_id'=>$item['config_id'], 'status' => 0, ])->first(); if(empty($res) || (!empty($res) && $res['is_send'] == 0) ){ throw new \Exception("优惠券未发放,暂不可领取"); } //发放优惠券，有多少张就添加多少张，这里扣除优惠券时，主要用不同的coupon_sn来区别 $onlyCoupon = $this->getCouponName($item['config_id']); if ($onlyCoupon['expire_type'] == 0) { $start_time = $onlyCoupon['expire_start_time']; $end_time = $onlyCoupon['expire_end_time']; } else { $start_time = date('Y-m-d H:i:s'); $end_time = date('Y-m-d H:i:s', time()+86400*$onlyCoupon['expire_type']); } $result = [ 'user_id' => $user['user_id'], 'config_id' => $item['config_id'], 'name' => $onlyCoupon['name'], 'get_type' => $onlyCoupon['get_type'], 'amount' => $onlyCoupon['amount'], 'require_price' => $onlyCoupon['require_price'], 'status' => 1, 'start_time' => $start_time, 'end_time' => $end_time, ]; for($i=0; $i < $item['quantity'];$i++){ $result['coupon_sn'] = 'B'.mt_rand(1, 10000) . strtoupper(uniqid(mt_rand(1, 10000))); $userCoupon = UserCouponBaseModel::create($result); } //扣除相应的优惠券数量,这里用到了锁表，防止并发时，优惠券为-1 $couponConfig = CouponConfigBaseModel::where('config_id',$item['config_id'])->lockForUpdate()->first(); if($couponConfig->left_quantity > 0 ){ if($couponConfig->left_quantity >= $item['quantity']){ $couponConfig->left_quantity = $couponConfig->left_quantity-$item['quantity']; $couponConfig->save(); }else{ throw new \Exception("优惠券剩余数量不够扣减"); } } $relate = [ 'coupon_id' => $userCoupon->coupon_id, 'user_id' => $user['user_id'], 'config_id' => $item['config_id'], 'activity_id' => $item['activity_id'] ]; ActivityCouponUserRelateBaseModel::create($relate); $relate[] = $this->getUserCouponRate($user['user_id'],$item['activity_id']); } return $relate;}
