## 架构概述
系统采用分层架构，包括API接口层、控制器层、服务层和数据访问层。天猫集成通过独立的控制器处理所有天猫相关请求，使用统一的数据模型进行数据交换，并通过定时任务实现与天猫平台的数据同步。

```mermaid
graph TB
Client[客户端] --> API[API接口]
API --> Controller[控制器]
Controller --> Service[服务层]
Service --> DAO[数据访问层]
DAO --> DB[(数据库)]
Cron[定时任务] --> API
API --> External[天猫平台]
```

## 详细组件分析

### 账户授权分析
天猫账户授权通过OAuth2.0协议实现，系统提供授权回调接口处理天猫返回的授权码，并使用TOP SDK完成令牌交换。

```mermaid
sequenceDiagram
participant 用户
participant kami_backend
participant 天猫平台
用户->>kami_backend : 请求授权
kami_backend->>天猫平台 : 重定向到天猫授权页面
天猫平台->>用户 : 显示授权页面
用户->>天猫平台 : 同意授权
天猫平台->>kami_backend : 回调携带授权码
kami_backend->>kami_backend : 调用OAuth2Login获取访问令牌
kami_backend->>用户 : 返回授权结果
```

- [account.go](file://api/card_info_t_mall_game/v1/account.go)

### 订单处理分析
订单处理流程包括订单创建、状态查询和数据同步，确保订单状态的准确性和一致性。

#### 订单创建流程
```mermaid
flowchart TD
Start([接收订单请求]) --> Validate["验证账号信息"]
Validate --> AccountValid{"账号有效?"}
AccountValid --> |否| ReturnError["返回账号错误"]
AccountValid --> |是| CreateOrder["创建订单记录"]
CreateOrder --> SaveDB["保存到数据库"]
SaveDB --> ReturnSuccess["返回订单号"]
ReturnError --> End([结束])
ReturnSuccess --> End
```

#### 订单查询流程
```mermaid
flowchart TD
Start([接收查询请求]) --> FindOrder["查找订单"]
FindOrder --> OrderExists{"订单存在?"}
OrderExists --> |否| ReturnEmpty["返回空结果"]
OrderExists --> |是| GetAccount["获取关联账号"]
GetAccount --> GetShop["获取店铺信息"]
GetShop --> Assemble["组装响应数据"]
Assemble --> ReturnResult["返回查询结果"]
ReturnEmpty --> End([结束])
ReturnResult --> End
```

- [card_t_mall_game_order.go](file://internal/model/card_t_mall_game_order.go)

### 数据同步分析
数据同步机制通过定时任务定期从天猫平台拉取最新数据，确保本地数据库与天猫平台数据的一致性。

```mermaid
sequenceDiagram
participant Cron as "定时任务"
participant API as "API服务"
participant DB as "本地数据库"
participant TMall as "天猫平台"
Cron->>API : 发起数据同步请求
API->>TMall : 调用天猫API获取数据
TMall-->>API : 返回最新数据
API->>DB : 保存账号数据
API->>DB : 保存店铺数据
API->>DB : 保存订单数据
API->>DB : 保存历史数据
DB-->>API : 确认保存结果
API-->>Cron : 返回同步结果
```

## 依赖分析
系统依赖于天猫TOP SDK进行API调用，依赖数据库存储账户和订单信息，并通过配置中心管理天猫API的配置参数。

```mermaid
graph TD
kami_backend --> tmall_sdk[天猫TOP SDK]
kami_backend --> database[MySQL数据库]
kami_backend --> config[配置中心]
kami_backend --> cron[定时任务系统]
tmall_sdk --> tmall_api[天猫API]
database --> storage[数据存储]
config --> settings[AppKey, AppSecret等]
```

- [t_mall_game_data_sync.go](file://utility/cron/t_mall_game_data_sync.go)
- [config.go](file://utility/config/config.go)

## 性能考虑
为确保系统性能，采用了以下优化措施：
- 使用数据库索引加速订单和账户查询
- 实现数据缓存减少重复查询
- 采用批量操作提高数据同步效率
- 设置合理的超时时间避免请求堆积
- 通过分页查询控制单次返回数据量

## 故障排除指南
### OAuth令牌过期
当OAuth令牌过期时，系统会返回授权错误。解决方案是重新发起授权流程，获取新的访问令牌。

### 消息重复消费
通过订单号的唯一性约束和幂等性设计，确保即使消息重复消费也不会产生重复订单。

### 订单状态不一致
通过定时数据同步机制定期校准本地订单状态与天猫平台状态，解决状态不一致问题。
