+# In-App Purchase 工具使用说明
+
+## 概述
+
+`InAppPurchaseUtil` 是一个基于 `in_app_purchase: ^3.2.3` 封装的内购工具类，提供了简单易用的 API 来处理应用内购买功能。
+
+## 功能特性
+
+- ✅ 单例模式，全局统一管理
+- ✅ 支持 iOS 和 Android 双平台
+- ✅ 自动处理购买流程和状态更新
+- ✅ 支持订阅型和消耗型产品
+- ✅ 支持恢复购买
+- ✅ 完整的回调机制
+- ✅ 详细的日志输出
+
+## 快速开始
+
+### 1. 初始化内购
+
+在应用启动或需要使用内购的页面初始化：
+
+```dart
+final InAppPurchaseUtil _iapUtil = InAppPurchaseUtil.instance;
+
+// 初始化并设置回调
+await _iapUtil.initialize(
+  onSuccess: (purchaseDetails) {
+    print('购买成功: ${purchaseDetails.productID}');
+    // 处理购买成功逻辑
+  },
+  onError: (purchaseDetails) {
+    print('购买失败: ${purchaseDetails.error?.message}');
+  },
+  onCancelled: (purchaseDetails) {
+    print('购买取消');
+  },
+  onPending: (purchaseDetails) {
+    print('购买处理中');
+  },
+  onRestore: (purchaseDetails) {
+    print('恢复购买成功: ${purchaseDetails.productID}');
+  },
+);
+```
+
+### 2. 加载产品信息
+
+```dart
+// 定义产品 ID
+final productIds = {
+  'com.yourapp.weekly',     // 周订阅
+  'com.yourapp.monthly',    // 月订阅
+  'com.yourapp.yearly',     // 年订阅
+  'com.yourapp.lifetime',   // 终身会员
+};
+
+// 加载产品
+bool success = await _iapUtil.loadProducts(productIds);
+
+if (success) {
+  // 获取产品列表
+  List<ProductDetails> products = _iapUtil.products;
+  
+  // 显示产品信息
+  for (var product in products) {
+    print('${product.title}: ${product.price}');
+  }
+}
+```
+
+### 3. 购买产品
+
+```dart
+// 方法 1: 通过产品 ID 购买（推荐）
+await _iapUtil.purchaseProductById('com.yourapp.yearly');
+
+// 方法 2: 通过产品详情购买
+final product = _iapUtil.getProductById('com.yourapp.yearly');
+if (product != null) {
+  await _iapUtil.purchaseProduct(product);
+}
+
+// 购买消耗型产品
+await _iapUtil.purchaseProduct(product, isConsumable: true);
+```
+
+### 4. 恢复购买
+
+```dart
+await _iapUtil.restorePurchases();
+// 恢复结果会在初始化时设置的 onRestore 回调中返回
+```
+
+## 完整示例
+
+参考 `in_app_purchase_example.dart` 文件查看完整使用示例。
+
+### Controller 中使用示例
+
+```dart
+class MyController extends GetxController {
+  final InAppPurchaseUtil _iapUtil = InAppPurchaseUtil.instance;
+  final isLoading = false.obs;
+  final products = <ProductDetails>[].obs;
+
+  @override
+  void onInit() {
+    super.onInit();
+    _initIAP();
+  }
+
+  Future<void> _initIAP() async {
+    // 初始化
+    await _iapUtil.initialize(
+      onSuccess: _handleSuccess,
+      onError: _handleError,
+    );
+
+    // 加载产品
+    await _loadProducts();
+  }
+
+  Future<void> _loadProducts() async {
+    final productIds = {'com.yourapp.premium'};
+    await _iapUtil.loadProducts(productIds);
+    products.value = _iapUtil.products;
+  }
+
+  void _handleSuccess(PurchaseDetails details) {
+    // 更新用户状态
+    // 解锁高级功能
+    // 显示成功提示
+  }
+
+  void _handleError(PurchaseDetails details) {
+    // 显示错误提示
+  }
+
+  // 购买
+  Future<void> purchase(String productId) async {
+    await _iapUtil.purchaseProductById(productId);
+  }
+
+  // 恢复购买
+  Future<void> restore() async {
+    await _iapUtil.restorePurchases();
+  }
+}
+```
+
+## API 文档
+
+### 初始化方法
+
+#### `initialize()`
+
+初始化内购功能并设置回调。
+
+**参数：**
+- `onUpdate`: 购买状态更新回调（可选）
+- `onSuccess`: 购买成功回调（可选）
+- `onError`: 购买失败回调（可选）
+- `onCancelled`: 购买取消回调（可选）
+- `onPending`: 购买等待中回调（可选）
+- `onRestore`: 恢复购买成功回调（可选）
+
+**返回值：** `Future<bool>` - 是否初始化成功
+
+### 产品管理方法
+
+#### `loadProducts(Set<String> productIds)`
+
+加载产品信息。
+
+**参数：**
+- `productIds`: 产品 ID 集合
+
+**返回值：** `Future<bool>` - 是否加载成功
+
+#### `getProductById(String productId)`
+
+根据产品 ID 获取产品详情。
+
+**参数：**
+- `productId`: 产品 ID
+
+**返回值：** `ProductDetails?` - 产品详情，未找到返回 null
+
+### 购买方法
+
+#### `purchaseProduct(ProductDetails productDetails, {bool isConsumable = false})`
+
+购买产品。
+
+**参数：**
+- `productDetails`: 产品详情
+- `isConsumable`: 是否是消耗型产品，默认 false
+
+**返回值：** `Future<bool>` - 是否发起购买成功
+
+#### `purchaseProductById(String productId)`
+
+通过产品 ID 购买产品。
+
+**参数：**
+- `productId`: 产品 ID
+
+**返回值：** `Future<bool>` - 是否发起购买成功
+
+#### `restorePurchases()`
+
+恢复购买。
+
+**返回值：** `Future<bool>` - 是否发起恢复成功
+
+### 其他方法
+
+#### `completePurchase(PurchaseDetails purchaseDetails)`
+
+完成购买（通常由工具类自动调用）。
+
+#### `dispose()`
+
+清理资源（在应用退出时调用）。
+
+## 配置说明
+
+### iOS 配置
+
+1. 在 App Store Connect 中创建内购商品
+2. 配置 StoreKit Configuration 文件（用于本地测试）
+3. 在 `Runner/Info.plist` 中添加必要的配置
+
+### Android 配置
+
+1. 在 Google Play Console 中创建应用内商品
+2. 配置结算权限
+3. 在 `AndroidManifest.xml` 中添加必要的权限
+
+## 注意事项
+
+### 服务器验证
+
+⚠️ **重要**: 当前工具类中的 `_verifyPurchase()` 方法只是一个占位实现。在生产环境中，你必须：
+
+1. 将购买凭证发送到你的后端服务器
+2. 服务器验证凭证的真实性（调用 Apple/Google 验证 API）
+3. 根据验证结果处理业务逻辑
+
+示例验证流程：
+
+```dart
+Future<bool> _verifyPurchase(PurchaseDetails purchaseDetails) async {
+  try {
+    // 发送到服务器验证
+    final response = await dio.post('/api/verify-purchase', data: {
+      'receipt': purchaseDetails.verificationData.serverVerificationData,
+      'productId': purchaseDetails.productID,
+      'platform': Platform.isIOS ? 'ios' : 'android',
+    });
+    
+    return response.data['valid'] == true;
+  } catch (e) {
+    debugPrint('验证购买失败: $e');
+    return false;
+  }
+}
+```
+
+### 测试建议
+
+1. **沙盒测试**: 在 iOS 和 Android 上使用测试账号进行沙盒测试
+2. **本地测试**: iOS 可以使用 StoreKit Configuration 文件进行本地测试
+3. **真实测试**: 在发布前进行真实的购买和恢复测试
+
+### 常见问题
+
+**Q: 为什么产品加载失败？**
+
+A: 检查以下几点：
+- 产品 ID 是否正确
+- 是否已在 App Store Connect/Google Play Console 中创建商品
+- 商品状态是否为"准备提交"或"批准销售"
+- 是否使用了正确的 Bundle ID/Package Name
+
+**Q: 购买后如何同步到服务器？**
+
+A: 在 `onSuccess` 回调中：
+1. 验证购买凭证
+2. 将购买信息同步到服务器
+3. 更新用户订阅状态
+
+**Q: 如何处理离线购买？**
+
+A: 工具会自动保存未完成的购买，在下次启动时自动处理。确保在应用启动时调用 `initialize()`。
