Angular 6-Window事件中的组件方法

Question

我在Angular 6中有一个window事件。在令牌事件中，我需要调用Angular方法，该怎么做？

openCheckout(order) {

  var handler = (<any>window).StripeCheckout.configure({
    key: 'pk_test_',
    locale: 'auto',
    token: function (token: any) {
      console.log(token.id);
      console.log(token.email);
      // --- makePayment ERRORS AS UNDEFINED
      this.makePayment(token.id, token.email);
      location.reload();
    }
  });

  handler.open({
    name: 'Name',
    description: 'Desc',
    currency: 'gbp',
    amount: order.transactionAmount,
    image: 'https://stripe.com/img/documentation/checkout/marketplace.png'
  });
}

预先感谢
