# Client Proxy Framework 使用指南
|
||
|
||
## 1. 框架概述
|
||
|
||
`client_proxy_framework` 是一个通用代理 API 框架，用于 Flutter 移动应用与后端 API 的通信。框架已封装好请求/响应的加密解密、字段映射等逻辑，换皮应用只需配置少量参数即可使用。
|
||
|
||
### 核心特性
|
||
|
||
- **自动加解密**：请求体和响应体自动进行 AES 加密/解密
|
||
- **字段映射**：框架自动将原始字段名转换为 V2 字段名，响应自动转换回来
|
||
- **强类型实体**：返回强类型实体类，开发者直接使用映射后的字段
|
||
- **统一响应**：`EntityResponse<T>` 提供强类型返回值
|
||
|
||
### 换皮应用：从零搭建
|
||
|
||
从零创建一个新的换皮应用（`skin_config.json`、`ClientBootstrap`、`main` 初始化顺序、Android/iOS 要点等），请阅读 **[《创建新换皮应用 — 步骤清单》](create_new_skin_app.md)**。
|
||
|
||
### 功能总览与用法
|
||
|
||
按模块整理的“功能 + 最小调用示例”请见 **[《Framework 功能与用法总览》](framework_feature_usage.md)**。
|
||
|
||
以首款换皮应用 **FunyMee** 为参考的 **视频首页**（`common_info` → 分类 → 按分类拉模板）数据流说明，见 **[《视频首页数据获取流程》](video_home_data_flow.md)**。
|
||
|
||
示例换皮配置文件 [`lib/src/config/skin_config.example.json`](../lib/src/config/skin_config.example.json) 的字段说明，见 **[《skin_config.example.json 字段说明》](skin_config_example.md)**。
|
||
|
||
---
|
||
|
||
## 2. 快速开始
|
||
|
||
### 2.1 添加依赖
|
||
|
||
在 `pubspec.yaml` 中添加：
|
||
|
||
```yaml
|
||
dependencies:
|
||
client_proxy_framework:
|
||
path: ../client_proxy_framework
|
||
```
|
||
|
||
### 2.2 实现配置
|
||
|
||
创建一个类继承 `AppConfig`：
|
||
|
||
```dart
|
||
import 'package:client_proxy_framework/client_proxy_framework.dart';
|
||
|
||
class MyAppConfig extends AppConfig {
|
||
@override
|
||
String get appId => 'YourAppId';
|
||
|
||
@override
|
||
String get packageName => 'com.yourapp.package';
|
||
|
||
@override
|
||
String get aesKey => 'your-16-char-key';
|
||
|
||
@override
|
||
String get preBaseUrl => 'https://pre-api.example.com';
|
||
|
||
@override
|
||
String get prodBaseUrl => 'https://api.example.com';
|
||
|
||
@override
|
||
String get proxyPath => '/quester/defender/summoner';
|
||
}
|
||
```
|
||
|
||
### 2.3 初始化
|
||
|
||
在 `main.dart` 中初始化：
|
||
|
||
```dart
|
||
void main() {
|
||
ApiClient.init(MyAppConfig());
|
||
runApp(const MyApp());
|
||
}
|
||
```
|
||
|
||
---
|
||
|
||
## 3. 设计理念
|
||
|
||
### 3.1 请求流程
|
||
|
||
```
|
||
调用层 (原始字段)
|
||
↓
|
||
ProxyClient.request()（自动加 `pkg`；默认加 `User_token`）
|
||
↓
|
||
字段映射 (原始 → V2)
|
||
↓
|
||
AES 加密
|
||
↓
|
||
发送请求
|
||
```
|
||
|
||
**请求头**：`ProxyClient` 会将 [AppConfig.packageName] 写入映射后的包名字段（原始名 `pkg`）；若已设置用户 token，默认还会写入 `User_token`。**`UserApi.fast_login` 等无需登录态接口**内部使用 `includeUserTokenInHeader: false`，避免把旧 token 打进 `filter_type`。其余请求也可在直接调用 `ProxyClient.request` 时传入该参数。
|
||
|
||
**请求体**：各 `*Api` 方法使用与《客户端指南》解密表一致的**原始字段名**（如 `referer`、`deviceId`、`fileUrls` / `contentType` / `content`）。
|
||
|
||
### 3.2 响应流程
|
||
|
||
```
|
||
接收响应
|
||
↓
|
||
AES 解密
|
||
↓
|
||
字段映射 (V2 → 原始)
|
||
↓
|
||
转换为实体类
|
||
↓
|
||
调用层 (实体类)
|
||
```
|
||
|
||

|
||
|
||
## 4. 配置项详解
|
||
|
||
### AppConfig 配置
|
||
|
||
| 配置项 | 必填 | 说明 |
|
||
|--------|------|------|
|
||
| `appId` | 是 | 应用标识，对应代理请求的 `hero_class` |
|
||
| `packageName` | 是 | 应用包名，如 `com.example.app` |
|
||
| `aesKey` | 是 | AES 加密密钥，长度需为 16 字符 |
|
||
| `preBaseUrl` | 是 | 预发环境域名 |
|
||
| `prodBaseUrl` | 是 | 生产环境域名 |
|
||
| `proxyPath` | 是 | 代理入口路径 |
|
||
| `debugBaseUrlOverride` | 否 | 调试时本地代理地址 |
|
||
| `fieldMapping` | 否 | 字段映射表，默认使用 `petsHeroAIFieldMapping` |
|
||

||
|
||
## 5. API 服务
|
||
|
||
所有 API 方法使用**原始字段名**，返回**强类型实体**。
|
||
|
||

// 访问实体
|
||
final data = res.data!;
|
||
final token = data.userToken;
|
||
} else {
|

// 处理错误
|
||
print('Error: ${res.msg}');
|

|
||
## 7. 设置用户 Token
|
||
|
||
登录成功后，调用以下方法设置用户 Token：
|
||
|
||
```dart
|
||
// 登录成功后
|
||
final res = await UserApi.fastLogin(...);
|
||
if (res.isSuccess) {
|
||
ApiClient.instance.setUserToken(res.data!.userToken);
|
||
}
|
||
|
||
// 登出时
|
||
ApiClient.instance.setUserToken(null);
|
||
```
|

|
||
## 8. 调试模式
|
||
|
||
框架会自动根据 `kDebugMode` 选择环境：
|
||
|
||
- **调试模式**：使用 `preBaseUrl`（或 `debugBaseUrlOverride`）
|
||
- **发布模式**：使用 `prodBaseUrl`
|
||
|

|
||
|
||
## 9. 字段映射
|
||
|
||
框架自动处理字段映射，调用层使用原始字段名。
|
||
|
||
### 请求字段映射（原始 → V2）
|
||
|
||
| 原始字段 | V2 字段 |
|
||
|----------|---------|
|
||
| app | sentinel |
|
||
| userId | asset |
|
||
| deviceId | origin |
|
||
| sign | resolution |
|
||
| referer | digest |
|
||
| activityId | warrior |
|
||
| country | vambrace |
|
||
| paymentMethod | resource |
|
||
| paymentType | ceremony |
|
||
| orderId | federation |
|
||
| signature | sample |
|
||
| purchaseData | merchant |
|
||
| taskId | tree |
|
||
| prompt | ledger |
|
||
| resolution | guild |
|
||
| srcImgUrls | commission |
|
||
| fileName1 | gateway |
|
||
| contentType | pauldron |
|
||
| expectedSize | stronghold |
|
||
|
||
### 响应字段映射（V2 → 原始）
|
||
|
||
| V2 字段 | 原始字段 |
|
||
|---------|----------|
|
||
| helm | code/响应码 |
|
||
| rampart | msg |
|
||
| sidekick | data |
|
||
| summon | productList |
|
||
| renew | paymentMethods |
|
||
| reveal | credits |
|
||
| reevaluate | userToken |

## 10. 代码示例
|
||
|
||
### 完整登录流程
|
||
|
||
```dart
|
||
import 'package:client_proxy_framework/client_proxy_framework.dart';
|
||
|
||
class AuthService {
|
||
static Future<bool> login() async {
|
||
final deviceId = await getDeviceId();
|
||
final sign = md5(deviceId).toUpperCase();
|
||
|
||
final res = await UserApi.fastLogin(
|
||
deviceId: deviceId,
|
||
sign: sign,
|
||
app: 'HAndroid', // 或 AppConfig.backendAppTypeAndroid / IOS
|
||
referer: 'organic',
|
||
);
|
||
|
||
if (res.isSuccess) {
|
||
final loginInfo = res.data!;
|
||
ApiClient.instance.setUserToken(loginInfo.userToken!);
|
||
UserState.setUserId(loginInfo.userId!);
|
||
UserState.setCredits(loginInfo.credits ?? 0);
|
||
return true;
|
||
}
|
||
return false;
|
||
}
|
||
}
|
||
```
|
||
|
||
### 完整支付流程
|
||
|
||
```dart
|
||
class PaymentService {
|
||
// 1. 获取商品列表
|
||
static Future<List<PaymentProductItem>> getProducts() async {
|
||
final res = await PaymentApi.getGooglePayActivities();
|
||
return res.data?.productList ?? [];
|
||
}
|
||
|
||
// 2. 获取支付方式
|
||
static Future<List<PaymentMethodItem>> getPaymentMethods(int activityId) async {
|
||
final res = await PaymentApi.getPaymentMethods(activityId: activityId);
|
||
return res.data?.paymentMethods ?? [];
|
||
}
|
||
|
||
// 3. 创建订单
|
||
static Future<String?> createOrder({
|
||
required String userId,
|
||
required String activityId,
|
||
required String paymentMethod,
|
||
}) async {
|
||
final res = await PaymentApi.createPayment(
|
||
app: ApiClient.instance.config.backendAppTypeAndroid,
|
||
userId: userId,
|
||
activityId: activityId,
|
||
paymentMethod: paymentMethod,
|
||
);
|
||
if (res.isSuccess) {
|
||
return res.data?.orderId;
|
||
}
|
||
return null;
|
||
}
|
||
|
||
// 4. Google Pay 回调
|
||
static Future<bool> verifyGooglePay({
|
||
required String signature,
|
||
required String purchaseData,
|
||
required String orderId,
|
||
required String userId,
|
||
}) async {
|
||
final res = await PaymentApi.googlepay(
|
||
signature: signature,
|
||
purchaseData: purchaseData,
|
||
orderId: orderId,
|
||
userId: userId,
|
||
);
|
||
return res.isSuccess;
|
||
}
|
||
}
|
||
```

## 11. 常见问题
|
||
|
||
### Q: 如何修改字段映射？
|
||
|
||
A: 覆盖 `AppConfig.fieldMapping`：
|
||
|
||
```dart
|
||
@override
|
||
FieldMapping get fieldMapping => const FieldMapping({
|
||
'deviceId': 'origin',
|
||
'userId': 'asset',
|
||
// ... 其他字段
|
||
});
|
||
```
|
||
|
||
### Q: 响应 data 为空怎么办？
|
||
|
||
A: 检查以下几点：
|
||
1. `ApiClient.init()` 是否已调用
|
||
2. 网络是否正常
|
||
3. `appId`、`aesKey` 等配置是否正确
