java - 将购买的商品详细信息发送到 PayPal？

问题描述

我需要发送购买的物品清单以及正在使用 Paypal 完成付款的物品，以便买家和供应商可以看到购买或出售了哪些产品。这是我为相同所做的片段，通过遵循PayPalCheckout 的 Github 代码，但我我们很抱歉对话框每次都得到。这是我的代码片段

private PayPalPayment prepareFinalCart() {

    List<PayPalItem> productsInCart = new ArrayList<>();
    double price;


    for (Program program : mPrograms) {
        if (null != program.programPrices.get(program.selectedPriceIndex).priceAfterDiscount) {
            price = program.programPrices.get(program.selectedPriceIndex).priceAfterDiscount;
        } else {
            price = program.programPrices.get(program.selectedPriceIndex).price;
        }
        PayPalItem item = new PayPalItem(program.type, 1, //Quantity
                new BigDecimal(price), //price
                Config.DEFAULT_CURRENCY, // currency
                 + String.valueOf(program.id)); // stock keeping unit

        productsInCart.add(item);
    }


    if (App.sCouponDetails != null) {
        App.sCouponDetails.calculateDiscount(mFinalCost);
    }


    PayPalItem[] items = new PayPalItem[productsInCart.size()];
    items = productsInCart.toArray(items);

    // Total amount
    BigDecimal subtotal = new BigDecimal(mFinalCost);

    // If you have shipping cost, add it here
    BigDecimal shipping = new BigDecimal("0.0");

    // If you have tax, add it here
    BigDecimal tax = new BigDecimal("0.0");

    PayPalPaymentDetails paymentDetails = new PayPalPaymentDetails(shipping, subtotal, tax);

    BigDecimal amount = subtotal.add(shipping).add(tax);


    // Getting Purchased Programs type
    StringBuilder programsType = new StringBuilder();
    for (int i = 0; i < mPrograms.size(); i++) {
        if (i == mPrograms.size() - 1) {
            programsType.append(mPrograms.get(i).type);
        } else {
            programsType.append(mPrograms.get(i).type).append(",");
        }
    }

    PayPalPayment payment = new PayPalPayment(amount, Config.DEFAULT_CURRENCY, "Total Amount: "/*programsType.toString()*/, Config.PAYMENT_INTENT);


    payment.items(items).paymentDetails(paymentDetails);


    // Custom field like invoice_number etc.,
    //payment.custom("This is text that will be associated with the payment that the app can use.");

    return payment;
}

请建议这里有什么问题？

解决方案

实际上那些 b/c/d/f 等参数来自 PayPalPayment 类。我刚刚给出了它的 Json 格式。这是 PayPalPayment 类的样子——PayPalPayment.java
