# 应用对接API文档

## 概述

本文档描述了验证平台应用对接API的详细说明，供第三方应用开发者集成使用。

**服务器地址**: `https://gendan.xyz`  
**API基础路径**: `/api/v1/app/{appKey}`

---

## 认证与加密

### 请求认证

- 公开接口：无需认证
- 需认证接口：请求头携带 `Authorization: Bearer {token}`
- Token通过登录接口获取

### 数据加密

平台支持AES和RC4两种加密方式，具体加密类型由应用配置决定。

#### AES加密

- 算法：AES-GCM
- 密钥长度：16/24/32字节（自动填充至32字节）
- 格式：Base64编码（nonce + ciphertext）

#### RC4加密

- 密钥长度：任意长度
- 格式：Base64编码

## API接口列表

### 1. 应用信息接口（公开）

#### 1.1 获取应用信息

**请求**
```
GET /api/v1/app/{appKey}/info
```

**响应**
```json
{
  "code": 200,
  "message": "success",
  "data": {
    "id": 1,
    "name": "应用名称",
    "description": "应用描述",
    "icon_url": "图标URL",
    "status": "active",
    "billing_type": "balance",
    "login_policy": "strict",
    "max_devices": 1,
    "multi_open_mode": "forbidden",
    "max_instances": 1,
    "enable_trial": false,
    "trial_balance": 0,
    "heartbeat_interval": 60,
    "heartbeat_timeout": 300
  }
}
```

#### 1.2 检查更新

**请求**
```
GET /api/v1/app/{appKey}/check-update?version=1.0.0
```

**参数说明**
- `version` (必填): 客户端当前版本号，必须存在于服务器版本列表中

**响应**
```json
{
  "code": 200,
  "message": "success",
  "data": {
    "has_update": true,
    "current_version": "1.0.0",
    "latest_version": "1.0.1",
    "download_url": "下载地址",
    "file_size": 1024000,
    "file_hash": "文件哈希",
    "entry_file": "入口文件",
    "update_notes": "更新说明",
    "update_strategy": "optional|forced",
    "update_type": "full|patch",
    "update_method": "auto|manual",
    "changelog": "更新日志",
    "files": [],
    "is_patch": false
  }
}
```

**错误响应**
```json
{
  "code": 400,
  "message": "请提供客户端版本号"
}
```

```json
{
  "code": 404,
  "message": "客户端版本不存在"
}
```

**更新判断逻辑**

基于版本ID（创建顺序）判断，与版本管理页面一致：

| has_update | update_strategy | 含义 |
|------------|-----------------|------|
| false | "" | 已是最新版本，无需更新 |
| true | optional | 有可选更新 |
| true | forced | 必须强制更新（存在更高ID的强制版本） |

**判断规则**
1. 如果存在 `ID > 客户端版本ID` 且 `update_strategy = "forced"` 的版本 → `has_update=true, update_strategy="forced"`
2. 如果存在 `ID > 客户端版本ID` 的版本（无强制更新） → `has_update=true, update_strategy="optional"`
3. 客户端版本ID已是最高 → `has_update=false`

**增量更新**
- 如果 `update_type` 为 `"patch"` 且存在以客户端版本为基础的增量包：
  - `is_patch`: true
  - `base_version`: 基础版本号
  - `patch_url`: 增量包下载地址
  - `patch_size`: 增量包大小
  - `patch_hash`: 增量包哈希

    {
      "id": 1,
      "title": "公告标题",
      "content": "公告内容",
      "type": "info",
      "is_top": true,

---

## 集成流程

1. 调用 `/info` 获取应用配置信息
2. 调用 `/register` 或 `/login` 获取用户Token
3. 使用Token调用需认证的接口
4. 定期调用 `/heartbeat` 保持在线状态
5. 根据需要调用其他接口

---

## C++ SDK使用示例

```cpp
#include "verify_client.hpp"

int main() {
    // 创建客户端
    verify::Client client("https://gendan.xyz", "your_app_key");
    
    // 获取应用信息
    auto info = client.getAppInfo();
    
    // 用户登录
    auto loginResult = client.login("username", "password", "device_id");
    std::string token = loginResult["token"].asString();
    client.setToken(token);
    
    // 心跳
    client.heartbeat("user_id", "device_id", "instance_id");
    
    // 充值
    client.recharge("username", "card_key", "device_id");
    
    return 0;
}
```
