Question

我在应用程序中使用Stripe作为支付处理器，并且有一些关于在使用Java库时获取错误响应而不是通过HTTP接收错误的问题，如description of errors codes on the official Stripe documentation

我用来根据以前用条纹创建的客户对象来收取信用卡的方法是：

public void charge(BigDecimal amount) throws AuthenticationException, InvalidRequestException, APIConnectionException, CardException, APIException {
    //Convert amount to cents
    NumberFormat usdCostFormat = NumberFormat.getCurrencyInstance(Locale.US);
    usdCostFormat.setMinimumFractionDigits(1);
    usdCostFormat.setMaximumFractionDigits(2);
    double chargeAmountDollars = Double.valueOf(usdCostFormat.format(amount.doubleValue()));
    int chargeAmountCents = (int) chargeAmountDollars * 100;
    Map<String, Object> chargeParams = new HashMap<String, Object>();
    chargeParams.put("amount", chargeAmountCents);
    chargeParams.put("currency", "usd");
    chargeParams.put("customer", subscription.getCustomerId());
    Charge charge = Charge.create(chargeParams);
    //Should I be inspecting the returned charge object and throwing my own errors here?
}

该方法会引发各种异常。 CardException似乎可能会向我提供有关付款错误的详细信息，但它实际上是用于检测拒绝和无效卡片参数之类的内容？这些异常会告诉我诸如“信用卡被拒绝“或”cvc代码不正确“或者我应该检查返回Charge对象以获取该数据？

调用充电方法的方法示例可能类似于：

BigDecimal discount = cost.multiply(BigDecimal.valueOf(discountPercentage).setScale(2, RoundingMode.HALF_EVEN));
cost = cost.subtract(discount);

if(cost.compareTo(BigDecimal.ZERO) > 0) {
    //Charge the credit card.
    try {
        paymentManager.charge(cost);
                    //Everything went ok, return success to user.
    } catch (AuthenticationException e) {
        //Authentication with API failed. Log error.
    } catch (InvalidRequestException e) {
        //Invalid parameters, log error.
    } catch (APIConnectionException e) {
        //Network communication failure. Try again.
    } catch (CardException e) {
        String errorCode = e.getCode();
        String errorMsg = e.getParam();
        if(errorCode.equals("incorrect_number")) {
            //Tell the user the cc number is incorrect.
        } else if(errorCode.equals("invalid_cvc")) {
            //Tell the user the cvc is wrong.
        }
        //This is a sample, production will check all possible errors.
    } catch (APIException e) {
        //Something went wrong on Stripes end.
    }
}

其次，我应该关注来自美国以外的付款还是Stripe会为我处理所有这些？ 我是否需要根据用户的区域设置检测货币并设置正确的货币代码，或者Stripe会将所有付款转换为美元，因为这是货币存入我的帐户的货币吗？ < / p>

更新根据我从Stripe的支持团队收到的电子邮件，非美国卡的发卡银行将自动执行从本地到美元的所有货币转换。我不必根据被收费卡的来源调整货币代码。

似乎CardException会为您提供与卡相关的（无效的CVC）和与付款相关（拒绝）的错误。

From the docs，此处如何使用Charge.create()方法：

如果充电成功，则返回充电对象。错误将是如果出现问题，我会退回一个常见的错误来源是卡无效或过期，或有效卡不足平衡。

来自Stripe Java documentation：

Card Errors
Type: card_error

Code                  Details
incorrect_number      The card number is incorrect
invalid_number        The card number is not a valid credit card number
invalid_expiry_month  The card's expiration month is invalid
invalid_expiry_year   The card's expiration year is invalid
invalid_cvc           The card's security code is invalid
expired_card          The card has expired

missing               There is no card on a customer that is being charged.
processing_error      An error occurred while processing the card.

至于货币，有一个货币值在地图中传递给Charge.create()方法，这似乎表示您希望收费的货币。我不知道这与结算有什么关系
