安装
标题为“安装”您可以使用我们的 AI 助手设置来安装插件。将 Capgo 技能添加到您的 AI 工具中,使用以下命令:
npx skills add https://github.com/Cap-go/capgo-skills --skill capacitor-plugins然后使用以下提示:
Use the `capacitor-plugins` skill from `Cap-go/capgo-skills` to install the `@capgo/native-purchases` plugin in my project.如果您更喜欢手动设置,请运行以下命令安装插件,并按照以下平台特定的说明进行操作:
-
安装包
终端窗口 bun add @capgo/native-purchases -
同步本地项目
终端窗口 bunx cap sync -
检查计费支持
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。
- 无需修改清单。确保您的产品已获得批准。
- 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 billing 权限到
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。
应用内购买服务示例
标题:应用内购买服务示例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)
async initialize() { const { isBillingSupported } = await NativePurchases.isBillingSupported(); if (!isBillingSupported) throw new Error('Billing unavailable');
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, });
await this.processTransaction(transaction); }
async buyMonthly(appAccountToken?: string) { const transaction = await NativePurchases.purchaseProduct({ productIdentifier: this.monthlySubId, planIdentifier: this.monthlyPlanId, // REQUIRED for Android subscriptions productType: PURCHASE_TYPE.SUBS, appAccountToken, });
await this.processTransaction(transaction); }
async restore() { await NativePurchases.restorePurchases(); await this.refreshEntitlements(); }
async openManageSubscriptions() { await NativePurchases.manageSubscriptions(); }
private async processTransaction(transaction: Transaction) { this.unlockContent(transaction.productIdentifier); this.validateOnServer(transaction).catch(console.error); }
private unlockContent(productIdentifier: string) { // persist entitlement locally console.log('Unlocked', productIdentifier); }
private async refreshEntitlements() { const { purchases } = await NativePurchases.getPurchases({ productType: PURCHASE_TYPE.SUBS, }); console.log('Current purchases', purchases); }
private async handleTransaction(transaction: Transaction) { console.log('StoreKit transaction update:', transaction); await this.processTransaction(transaction); }
private async validateOnServer(transaction: Transaction) { await fetch('/api/validate-purchase', { method: 'POST', body: JSON.stringify({ transactionId: transaction.transactionId, receipt: transaction.receipt, purchaseToken: transaction.purchaseToken, }), }); }}必需的应用内购买选项
标题:必需的应用内购买选项| 选项 | 平台 | 描述 |
|---|---|---|
productIdentifier | iOS + Android | SKU/Product ID |
productType | 仅 Android | PURCHASE_TYPE.INAPP 或 PURCHASE_TYPE.SUBS或 INAPP. 默认值 SUBS . 总是设置为 |
planIdentifier | 用于订阅 | 仅 Android 订阅项 |
billingPlanType | iOS 订阅 | StoreKit billing 计划用于购买。使用 'monthly' 每月付款,12 个月的承诺期 product.pricingTerms 当 |
quantity | exposes | iOS 1仅限在应用内购买, |
appAccountToken | 。Android 总是购买一个项目。 | iOS + Android |
isConsumable | 购买凭证 | UUID/字符串将购买与您的用户关联。iOS 需要 UUID;Android 可以接受最多 64 个字符的任何混淆字符串。 true Android false. |
检查资格状态
标题:检查资格状态使用 getPurchases() 查看每个商店报告的交易的跨平台视图:
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,以及StoreKit 2监听器支持。应用内购买需要服务器收据验证。 - Android:
isActive/expirationDate不被填充;请使用Google Play开发者API调用purchaseToken为了获得权威的状态。purchaseState必须是PURCHASED并且isAcknowledged必须是true.
API快速参考
API快速参考isBillingSupported()– 检查StoreKit / Google Play的可用性。getProduct()/getProducts()– 获取价格、本地化标题、描述、引导性优惠和支持的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()– 回放历史购买并同步到当前设备。getPurchases()– 列出所有iOS交易或Play Billing购买。manageSubscriptions()– 打开本机订阅管理UI。addListener('transactionUpdated')– iOS 应用启动时处理待处理的 StoreKit 2 交易 (仅限 iOS).
最佳实践
最佳实践- 显示商店价格 – Apple 需要显示
product.title并且product.priceString不应硬编码。 - 使用
appAccountToken– 根据用户 ID 确定生成 UUID (v5) 来将购买与帐户关联。 - 验证服务器端 – 发送
receipt(仅限 iOS) /purchaseToken(Android)向您的后端进行验证。 - 优雅地处理错误 – 检查用户取消、网络故障和不支持的计费环境。
- 彻底测试 – 遵循 iOS沙盒指南 和 (见iOS沙盒指南).
- Android沙盒指南 提供恢复和管理
restorePurchases()– 添加UI按钮,连接到manageSubscriptions().
after the purchase flow works, use the Revenue Playbook to plan your first paid funnel: product scope, ASO, pricing, paywall placement, analytics, and churn feedback.
Troubleshooting
Section titled “Troubleshooting”Products not loading
- 确保 bundle ID / 应用程序 ID 与商店配置匹配。
- 确认产品 ID 为活跃状态且已批准(App Store)或激活(Google Play)。
- 等待创建产品后几小时;商店传播不是即刻的。
Purchase cancelled or stuck
- 用户可以在流程中取消;将调用包裹在
try/catch并且友好的错误消息。 - 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 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。 - 在 Android 上,始终使用 Google Play Developer API
purchaseToken以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。
