已完成的配置 #

• RevenueCat后台已配置对应产品
• Apple开发者后台创建了订阅产品，且开启应用内购买权限

相关代码 #

主入口代码 #

Future<void> main() async {
   await dotenv.load();

  WidgetsFlutterBinding.ensureInitialized();

 
  RevenueCat.init();

  await Firebase.initializeApp(
    name: "thraive-5f2ab",
    options: DefaultFirebaseOptions.currentPlatform,
  );
  runApp(MyApp());
}

RevenueCat工具类 #

import 'package:flutter_dotenv/flutter_dotenv.dart';
import 'package:purchases_flutter/models/offerings_wrapper.dart';
import 'package:purchases_flutter/purchases_flutter.dart';

class RevenueCat {
  static Future init() async {
    final revenueCat =
        PurchasesConfiguration(dotenv.env['REVENUE_CAT_APPLE_API_KEY']!);
    await Purchases.configure(revenueCat);
  }

  static Future<List<Offering>> fetchOfferss() async {
    print('fetchOffers()');
    try {
      final offerings = await Purchases.getOfferings();
      final current = offerings.current;
      return current == null ? [] : [current];
    } catch (e) {
      return [];
    }
  }

  static Future<bool> purchasePackage(Package package) async {
    print('purchasePackage()');
    try {
      await Purchases.purchasePackage(package);


      return true;
    } catch (e) {
      print('error: ${e}');
      return false;
    }
  }
}

订阅购买按钮处理代码 #

buyFirstSubscription() async {
    print('[fetchOffers]');
    final offerings = await RevenueCat.fetchOfferss();
    if (offerings.isEmpty) {
      Utils.showSnackBar('No subscriptions!');
    } else {
      final offer = offerings.first;
      final packages = offerings
          .map((offer) => offer.availablePackages)
          .expand((pair) => pair)
          .toList();
      // print(packages);
      bool purchaseResult = await RevenueCat.purchasePackage(packages[0]);
    }
  }

排查与解决步骤 #

1. 验证沙盒测试账号
   从日志中的customerMessage可以看出，沙盒账号验证失败。必须使用Apple官方沙盒测试账号（不是个人Apple ID），确保账号有效、密码正确，且退出设备上的个人Apple ID后再用沙盒账号登录。

2. 统一地区设置
   日志显示storefront-country-code=USA，需确保沙盒账号所属地区为美国，同时设备的App Store地区也设置为美国，避免地区不匹配导致验证失败。

3. 修正RevenueCat初始化时机
   主代码中RevenueCat.init()未加await，可能导致初始化未完成就执行后续操作，修改如下：

   Future<void> main() async {
     await dotenv.load();
     WidgetsFlutterBinding.ensureInitialized();
     await RevenueCat.init(); // 加上await确保初始化完成
     await Firebase.initializeApp(
       name: "thraive-5f2ab",
       options: DefaultFirebaseOptions.currentPlatform,
     );
     runApp(MyApp());
   }
   

4. 优化购买错误处理
   原购买方法仅返回bool，无法区分错误类型，建议修改为捕获具体错误并验证订阅状态：

   static Future<bool> purchasePackage(Package package) async {
     print('purchasePackage()');
     try {
       final customerInfo = await Purchases.purchasePackage(package);
       // 检查是否有激活的订阅权限
       return customerInfo.entitlements.active.isNotEmpty;
     } catch (e) {
       if (e is PlatformException) {
         print('Purchase error code: ${e.code}, message: ${e.message}');
         // 区分用户取消、支付失败等不同错误
         if (e.code == "USER_CANCELLED") {
           print("User cancelled purchase");
         }
       }
       print('error: ${e}');
       return false;
     }
   }
   

5. 检查应用签名与权限配置

   • 确认Xcode中应用的Bundle ID与Apple开发者后台、RevenueCat后台完全一致
   • 确保已开启In-App Purchase capability，且Provisioning Profile包含该权限
   • 检查应用的签名是否有效，避免因签名问题导致无法连接App Store服务

6. 确认网络环境
   沙盒服务需要稳定的网络，避免使用VPN或代理导致连接异常，确保设备能正常访问Apple沙盒服务器。
