// AddItemCard 给用户添加道具卡
|
||
// 功能描述：
|
||
// - 根据道具卡模板ID查询模板信息
|
||
// - 验证道具卡状态是否有效（status=1）
|
||
// - 创建用户道具卡记录，继承模板的有效期设置
|
||
// - 支持批量添加，quantity参数控制数量
|

//
|
||
// 参数说明：
|
||
// - ctx: 上下文
|
||
// - userID: 用户ID
|
||
// - cardID: 道具卡模板ID
|
||
// - quantity: 添加数量，如果<=0则默认为1
|

//
|
||
// 返回说明：
|
||
// - error: 错误信息，包括数据库查询失败、模板不存在等情况
