如何修复“yourAPI未定义”

Question

我现在在研究反应本土化。在工作的时候，我遇到了这个问题。“yourAPI未定义”

import RNIap, {
  purchaseErrorListener,
  purchaseUpdatedListener,
  type ProductPurchase,
  type PurchaseError
} from 'react-native-iap';

class RootComponent extends Component<*> {
  purchaseUpdateSubscription = null
  purchaseErrorSubscription = null

  componentDidMount() {
    this.purchaseUpdateSubscription = purchaseUpdatedListener((purchase: ProductPurchase) => {
      console.log('purchaseUpdatedListener', purchase);
      const receipt = purchase.transactionReceipt;
      if (receipt) {
        yourAPI.deliverOrDownloadFancyInAppPurchase(purchase.transactionReceipt)
        .then((deliveryResult) => {
          if (isSuccess(deliveryResult)) {

            if (Platform.OS === 'ios') {
              RNIap.finishTransactionIOS(purchase.transactionId);
            } else if (Platform.OS === 'android') {
              // If consumable (can be purchased again)
              RNIap.consumePurchaseAndroid(purchase.purchaseToken);
              // If not consumable
              RNIap.acknowledgePurchaseAndroid(purchase.purchaseToken);
            }
          } else {
            // Retry / conclude the purchase is fraudulent, etc...
          }
        });
      }
    });

    this.purchaseErrorSubscription = purchaseErrorListener((error: PurchaseError) => {
      console.warn('purchaseErrorListener', error);
    });
  }

  componentWillUnmount() {
    if (this.purchaseUpdateSubscription) {
      this.purchaseUpdateSubscription.remove();
      this.purchaseUpdateSubscription = null;
    }
    if (this.purchaseErrorSubscription) {
      this.purchaseErrorSubscription.remove();
      this.purchaseErrorSubscription = null;
    }
  }
}

在这里我不确定什么是'yourAPI.deliverOrDownloadFancyInAppPurchase'？请帮助，任何人谁能知道‘你的can’？

这实际上是您的api :)这意味着当一个产品是用本地的应用程序内购买，您想要调用您的api (后端)。在一个游戏中的四个例子，你可以出售一个初学者包与应用程序内购买，首先用户将支付一个价值谷歌发挥或应用商店为这个初学者包。你应该知道这个动作是否成功地完成了，你应该把这个初学者工具包给用户。为此，您应该在这个监听器中进行调用，比如backendApi.sold(purchase.transactionReceipt).then((result) => {});。
