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;
}
