支付问题的 Siri 集成

Question

在我的应用程序中，我只支持欧元和美元货币。因此，例如，当用户尝试使用 Siri 向英镑付款时，我要求他在欧元和美元之间进行选择。

之后我在屏幕上看到：

• 100 美元
• 100 欧元

如果我在intent.currencyAmount!.currencyCode 中选择 100 美元，我总是有 GBP（但用户选择了美元）。很奇怪。

这是我的代码：

func resolveCurrencyAmount(forSendPayment intent: INSendPaymentIntent, with completion: @escaping (INCurrencyAmountResolutionResult) -> Void) {
        if let currencyAmount = intent.currencyAmount { // need to check if we have proper value
            if let amount = currencyAmount.amount {

                if amount.doubleValue == 0 { // wrong amount
                    completion(INCurrencyAmountResolutionResult.unsupported())
                    return
                }

                if let currencyCode = currencyAmount.currencyCode {
                    if let _ = EnumCurrency(rawValue: currencyCode) { // we found currency code that we know
                        completion(INCurrencyAmountResolutionResult.success(with: INCurrencyAmount(amount: NSDecimalNumber(value: abs(amount.doubleValue)), currencyCode: currencyCode)))
                        return
                    }
                }


                // if we are here so we don't have proper currency, try to offer user to choose the same amount but with all possible currencies
                let disambiguationArray: [INCurrencyAmount] = EnumCurrency.allValues.map({ (currency) -> INCurrencyAmount in
                    return INCurrencyAmount(amount: NSDecimalNumber(value: abs(amount.doubleValue)), currencyCode: currency.rawValue)
                })
                completion(INCurrencyAmountResolutionResult.disambiguation(with: disambiguationArray))
            }
        }
        else { // we don't have value
            completion(INCurrencyAmountResolutionResult.needsValue())
        }
    }

enum EnumCurrency : String {
    case EUR = "EUR"
    case USD = "USD"

    static let allValues = [EUR, USD]
}

更新：如何重现（根据大卫的问题）：

1) 创建一个新的意图扩展

2) 在 plist 文件中只留下一种意图：http://take.ms/pt16N

3) 您的 IntentHandler 类（将由 xCode 创建）必须确认 INSendPaymentIntentHandling 协议

4) 在 IntentHandler 类中添加：

func resolveCurrencyAmount(forSendPayment intent: INSendPaymentIntent, with completion: @escaping (INCurrencyAmountResolutionResult) -> Void) {
            if let currencyAmount = intent.currencyAmount { // need to check if we have proper value
                if let amount = currencyAmount.amount {

                    if amount.doubleValue == 0 { // wrong amount


                 completion(INCurrencyAmountResolutionResult.unsupported())
                    return
                }

                if let currencyCode = currencyAmount.currencyCode {
                    if let _ = EnumCurrency(rawValue: currencyCode) { // we found currency code that we know
                        completion(INCurrencyAmountResolutionResult.success(with: INCurrencyAmount(amount: NSDecimalNumber(value: abs(amount.doubleValue)), currencyCode: currencyCode)))
                        return
                    }
                }


                // if we are here so we don't have proper currency, try to offer user to choose the same amount but with all possible currencies
                let disambiguationArray: [INCurrencyAmount] = EnumCurrency.allValues.map({ (currency) -> INCurrencyAmount in
                    return INCurrencyAmount(amount: NSDecimalNumber(value: abs(amount.doubleValue)), currencyCode: currency.rawValue)
                })
                completion(INCurrencyAmountResolutionResult.disambiguation(with: disambiguationArray))
            }
        }
        else { // we don't have value
            completion(INCurrencyAmountResolutionResult.needsValue())
        }
    }

enum EnumCurrency : String {
    case EUR = "EUR"
    case USD = "USD"

    static let allValues = [EUR, USD]
}

// MARK: - Confirm

    func confirm(sendPayment intent: INSendPaymentIntent, completion: @escaping (INSendPaymentIntentResponse) -> Void) {
// success
        completion(INSendPaymentIntentResponse(code: INSendPaymentIntentResponseCode.success, userActivity: nil))

}

// MARK: - Handle

    func handle(sendPayment intent: INSendPaymentIntent, completion: @escaping (INSendPaymentIntentResponse) -> Void) {

// just for test
completion(INSendPaymentIntentResponse(code: .failureRequiringAppLaunch, userActivity: userActivity))
}

5) 你可以用 Siri 启动：你会看到，如果你选择中国货币或任何其他非常规货币，然后我在代码中让你在 EUR 和 USD 之间进行选择，但之后在 RESOLVE 函数中（调用时调用siri 想在更多时间解析货币）你会得到中国货币（所以你不需要像大卫问的那样为按钮添加任何代码，因为所有按钮界面都将由 Siri 提供）

Answer 1

我创建了这个问题： Siri and wrong currency

您需要做的就是确认用户选择的货币。 您的确认方法执行错误，您应该使用以下方式确认货币：

let response = INSendPaymentIntentResponse(code: .ready, userActivity: nil)
response.paymentRecord = INPaymentRecord(
    payee: intent.payee, 
    payer: nil, 
    currencyAmount: intent.currencyAmount, 
    paymentMethod: nil, 
    note: nil, 
    status: .pending, 
    feeAmount: nil)
completion(response)

Answer 2

在 confirmSendPayment 方法中，创建 INSendPaymentIntentResponse 实例并将 INPaymentRecord 实例分配给 paymentRecord 属性。我做了一个辅助方法来做这件事。

func confirm(sendPayment intent: INSendPaymentIntent, completion: (INSendPaymentIntentResponse) -> Void) {
    let response = INSendPaymentIntentResponse(code: .Ready, userActivity: nil)
    response.paymentRecord = getPaymentRecord(fromIntent: intent)
    completion(response)
}

private func getPaymentRecord(fromIntent intent: INSendPaymentIntent) -> INPaymentRecord? {
    let currencyAmount = INCurrencyAmount(amount: intent.currencyAmount?.amount ?? 0.0, currencyCode: "INR")
    return INPaymentRecord(payee: intent.payee, payer: nil, currencyAmount: currencyAmount, paymentMethod: nil, note: nil, status: .Pending)
}

希望这会有所帮助。
