示例用法

restorePurchases

恢复用户的之前购买信息并将其与使用相同的应用用户ID的任何用户关联。

import { NativePurchases } from '@capgo/native-purchases';

await NativePurchases.restorePurchases();

getAppTransaction

获取应用交易信息，提供有关用户最初下载或购买应用的详细信息。

import { NativePurchases } from '@capgo/native-purchases';

const { appTransaction } = await NativePurchases.getAppTransaction();

// Check if user downloaded before version 2.0.0 (when subscription was added)
if (compareVersions(appTransaction.originalAppVersion, '2.0.0') < 0) {
  // User gets free access - they downloaded before subscriptions
  grantFreeAccess();
}

isEntitledToOldBusinessModel

比较应用交易中的原始应用版本与目标版本，以确定用户是否有权从较早的商业模式中获得特征。

import { NativePurchases } from '@capgo/native-purchases';

// Check if user downloaded before version 2.0.0/build 42 (when subscription was added)
const result = await NativePurchases.isEntitledToOldBusinessModel({
  targetVersion: '2.0.0',
  targetBuildNumber: '42'
});

if (result.isOlderVersion) {
  console.log(`User downloaded v${result.originalAppVersion}, granting free access`);
  grantFreeAccess();
}

purchaseProduct

开始为给定产品启动购买流程。对于Android订阅，传递Google Play的基本计划ID作为 planIdentifier对于支持的iOS订阅，传递 billingPlanType: 'monthly'.

import { NativePurchases, PURCHASE_TYPE } from '@capgo/native-purchases';

await NativePurchases.purchaseProduct({
  productIdentifier: 'com.example.premium.monthly',
  planIdentifier: 'monthly-plan',
  productType: PURCHASE_TYPE.SUBS,
});

支持的iOS版本上，StoreKit可以通过

在购买前在您的付费墙上显示这些条款： pricingTerms全局参考

import { NativePurchases, PURCHASE_TYPE } from '@capgo/native-purchases';

const { products } = await NativePurchases.getProducts({
  productIdentifiers: ['com.example.premium.yearly'],
  productType: PURCHASE_TYPE.SUBS,
});

const yearlyProduct = products.find(
  (product) => product.identifier === 'com.example.premium.yearly',
);
const monthlyCommitment = yearlyProduct?.pricingTerms?.find(
  (term) => term.billingPlanType === 'monthly',
);

if (yearlyProduct && monthlyCommitment) {
  console.log('Monthly price:', monthlyCommitment.billingDisplayPrice);
  console.log('Total commitment:', monthlyCommitment.commitmentInfo?.priceString);

  const transaction = await NativePurchases.purchaseProduct({
    productIdentifier: yearlyProduct.identifier,
    productType: PURCHASE_TYPE.SUBS,
    billingPlanType: 'monthly',
  });

  console.log('Billing plan:', transaction.billingPlanType);
  console.log('Commitment ends:', transaction.commitmentInfo?.expirationDate);
}
