javascript - 无法在 ionic-native/in-app-purchase-2 中完成交易

Question

我正在使用 Ionic 4/Angular 8/Cordova 开发应用程序

我已经安装了In App Purchase 2并设置它。 Apple Developer 和 Sandbox 帐户都可以。

产品注册没问题:

registerProduct() {
    this.iap.verbosity = this.iap.DEBUG;

    this.iap.register({
        id: MONEYCOMBO_KEY,
        type: this.iap.CONSUMABLE
    })

    this.registerHandlersForPurchase(MONEYCOMBO_KEY)

    this.product = this.iap.get(MONEYCOMBO_KEY)

    this.iap.refresh()

    this.iap.when(MONEYCOMBO_KEY).updated((p) => {
        this.product = p
        this.title = p.title
        this.price = p.price
    })
}

事件处理程序:

registerHandlersForPurchase(productId) {
    let self = this.iap;

    this.iap.when(productId).updated(function (product) {
        if (product.loaded && product.valid && product.state === self.APPROVED && product.transaction != null) {
            product.finish();
        }
    });

    this.iap.when(productId).registered((product: IAPProduct) => {
        // alert(` owned ${product.owned}`);
    });

    this.iap.when(productId).owned((product: IAPProduct) => {
        console.error('finished')
        product.finish();
    });

    this.iap.when(productId).approved((product: IAPProduct) => {
        // alert('approved');
        product.finish();
    });

    this.iap.when(productId).refunded((product: IAPProduct) => {
        // alert('refunded');
    });

    this.iap.when(productId).expired((product: IAPProduct) => {
        // alert('expired');
    });
}

购买方式:

buyMoneyCombo(form: NgForm) {
    this.registerHandlersForPurchase(MONEYCOMBO_KEY)
    this.date = form.value.date
    this.iap.order(MONEYCOMBO_KEY)
    this.iap.refresh()
}

问题:

控制台说:

"InAppPurchase[js]: product test has a transaction in progress: 1000000628239595"

交易无法完成。为什么？

Answer 1

因此，经过一周的研究，我找到了解决方案。

而且没有问题:
交易完成后显示来自 Apple 的消息:

"InAppPurchase[js]: product test has a transaction in progress: 1000000628239595"

并且必须在内部声明所有购买逻辑:

this.iap.when(MONEYCOMBO_KEY).approved((product: IAPProduct) => {
        product.finish()
        this.getMoney()
    })
