## 简介
沃尔玛卡密管理API提供了一套完整的接口，用于管理沃尔玛礼品卡账户、订单处理和分组管理。该系统支持账户创建、状态检测、订单提交、分组管理等功能，专为高效处理沃尔玛卡密兑换而设计。API具备批量验证、状态重置、分组统计等高级功能，确保账户状态与沃尔玛平台保持同步，并遵守平台的调用限制。

## 项目结构
沃尔玛卡密管理模块位于`api/card_info_walmart`目录下，采用分层架构设计。该模块包含v1版本的API定义和对应的控制器实现，分别位于`v1`子目录和`internal/controller/card_info_walmart`目录中。数据模型定义在`internal/model/entity`目录下，常量定义在`internal/consts`目录中。

## 核心组件
沃尔玛卡密管理API的核心组件包括账户管理、分组管理、订单处理和统计分析四大模块。账户管理模块负责沃尔玛账户的创建、更新、删除和状态检测；分组管理模块提供账户分组的增删改查和统计功能；订单处理模块处理卡密兑换请求和订单状态管理；统计分析模块提供账户和订单的汇总数据。

## 架构概览
沃尔玛卡密管理API采用典型的三层架构：API接口层、业务逻辑层和数据访问层。API接口层定义了所有对外暴露的HTTP端点；业务逻辑层（控制器）处理具体的业务逻辑；数据访问层通过实体模型与数据库交互。系统通过常量文件定义了各种状态码和枚举值，确保代码的一致性和可维护性。

## 性能考虑
沃尔玛卡密管理API在设计时充分考虑了性能因素。批量操作采用流式处理，避免内存溢出；数据库查询使用索引优化，提高查询效率；状态检测采用缓存机制，减少对沃尔玛平台的频繁调用。系统还实现了限流机制，防止对沃尔玛API的过度调用。

## 故障排除指南
当遇到问题时，可按照以下步骤进行排查：
1. 检查账户Cookie是否有效，可通过状态检测接口验证
2. 确认账户状态是否正常，禁用的账户无法处理订单
3. 检查分组配置是否正确，确保账户分配到正确的分组
4. 查看订单历史，分析失败订单的具体原因
5. 检查系统日志，获取详细的错误信息
