查看计费支持
import { NativePurchases } from '@capgo/native-purchases';const { isBillingSupported } = await NativePurchases.isBillingSupported();if (!isBillingSupported) {throw new Error('Billing is not available on this device');} -
直接从商店中加载产品
import { NativePurchases, PURCHASE_TYPE } from '@capgo/native-purchases';const { products } = await NativePurchases.getProducts({productIdentifiers: ['com.example.premium.monthly','com.example.premium.yearly','com.example.one_time_unlock'],productType: PURCHASE_TYPE.SUBS, // Use PURCHASE_TYPE.INAPP for one‑time products});products.forEach((product) => {console.log(product.title, product.priceString);}); -
实现购买和恢复流程
import { NativePurchases, PURCHASE_TYPE } from '@capgo/native-purchases';const monthlyPlanId = 'monthly-plan'; // Base Plan ID from Google Play Consoleconst transaction = await NativePurchases.purchaseProduct({productIdentifier: 'com.example.premium.monthly',planIdentifier: monthlyPlanId, // REQUIRED for Android subscriptions, ignored on iOSproductType: PURCHASE_TYPE.SUBS,quantity: 1,});console.log('Transaction ID', transaction.transactionId);await NativePurchases.restorePurchases();- 在 App Store Connect 中创建应用内产品和订阅。
- 使用 StoreKit Local Testing 或 Sandbox 测试者进行 QA。
- 不需要修改清单。确保您的产品已通过审批。
- 在 Google Play Console 中创建应用内产品和订阅。
- 上传至少一个内部测试版本并添加许可测试者。
- 添加
AndroidManifest.xml:
<uses-permission android:name="com.android.vending.BILLING" /> - 在 App Store Connect 中创建应用内产品和订阅。
购买服务示例
标题:购买服务示例import { NativePurchases, PURCHASE_TYPE, Transaction } from '@capgo/native-purchases';import { Capacitor } from '@capacitor/core';
class PurchaseService { private premiumProduct = 'com.example.premium.unlock'; private monthlySubId = 'com.example.premium.monthly'; private monthlyPlanId = 'monthly-plan'; // Base Plan ID (Android only)

const { products } = await NativePurchases.getProducts({ productIdentifiers: [this.premiumProduct, this.monthlySubId], productType: PURCHASE_TYPE.SUBS, });
console.log('Loaded products', products);
if (Capacitor.getPlatform() === 'ios') { NativePurchases.addListener('transactionUpdated', (transaction) => { this.handleTransaction(transaction); }); } }
async buyPremium(appAccountToken?: string) { const transaction = await NativePurchases.purchaseProduct({ productIdentifier: this.premiumProduct, productType: PURCHASE_TYPE.INAPP, appAccountToken, });

检查授权状态
标题:检查授权状态使用 getPurchases() 查看每个商店报告的所有交易的跨平台视图:
import { NativePurchases, PURCHASE_TYPE } from '@capgo/native-purchases';
const { purchases } = await NativePurchases.getPurchases({ productType: PURCHASE_TYPE.SUBS,});
purchases.forEach((purchase) => { if (purchase.isActive && purchase.expirationDate) { console.log('iOS sub active until', purchase.expirationDate); }
const isAndroidIapValid = ['PURCHASED', '1'].includes(purchase.purchaseState ?? '') && purchase.isAcknowledged;
if (isAndroidIapValid) { console.log('Grant in-app entitlement for', purchase.productIdentifier); }});平台行为
标题:平台行为- iOS: 订阅包括
isActive,expirationDate,willCancel,和 StoreKit 2 监听器支持。内购需要服务器接收验证。 - Android:
isActive/expirationDate不提供此信息,请使用Google Play Developer API进行查询purchaseToken为获取最新信息,请访问官方网站。purchaseState必须PURCHASED和isAcknowledged必须true.
API快速参考指南
标题:API快速参考指南isBillingSupported()– 检查StoreKit / Google Play的可用性。getProduct()/getProducts()– 获取价格、本地化标题、描述、推广活动和支持的iOS定价条款。purchaseProduct()– 初始化StoreKit 2或Billing客户端购买流程,包括iOS月度承诺付款计划。restorePurchases()– 重放历史购买并同步到当前设备。getPurchases()– iOS 或 Play Billing 的所有交易列表.manageSubscriptions()– 打开本地订阅管理 UI.addListener('transactionUpdated')– 当应用启动时,处理待处理的 StoreKit 2 交易(仅限 iOS)。
最佳实践
标题:最佳实践- 显示商店价格 – Apple 需要显示
product.title且product.priceString;绝不硬编码. - 使用
appAccountToken– 根据用户 ID 确定生成 UUID (v5) 以便将购买与帐户关联. - 在服务器端验证 – 发送
receipt(iOS) /purchaseToken(Android) 到您的后端进行验证。 - 处理错误 – 检查用户取消、网络故障和不支持的计费环境。
- 进行彻底的测试 – 遵循 iOS sandbox 指南 和 Android sandbox 指南.
- 提供恢复 & 管理 – 添加 UI 按钮,连接到
restorePurchases()和manageSubscriptions().
收入下一步
收入下一步购买流程完成后,使用 收入手册 规划您的第一个付费渠道:产品范围、ASO、定价、付费墙位置、分析和流失反馈。
故障排除
故障排除产品未加载
- 确保bundle ID/应用程序ID与商店配置匹配。
- 确认产品ID处于激活状态并已批准(App Store)或激活(Google Play)。
- 创建产品后等待几小时;商店传播不是即时的。
购买已取消或卡住
- 用户可以在流程中取消;.wrap调用在
try/catch并显示友好的错误消息。 - 对于 Android,确保测试帐户从 Play Store(内部跟踪)安装应用程序,以便Billing正常工作。
- 在设备上运行时,检查logcat/Xcode以查找billing错误。
订阅状态不正确
- 使用
getPurchases()来比较商店数据与您的本地权利缓存。 - On Android, always query the Google Play Developer API with the
purchaseToken来获取过期日期或退款状态。 - 在 iOS 上,检查
isActive/expirationDate并验证收据以检测退款或撤销
