一. 证书创建

官方文档

https://developer.apple.com/cn/help/account/configure-app-capabilities/configure-apple-pay

• 创建商家标识符
• 创建付款处理证书

CSR创建参考文档
https://developer.apple.com/cn/help/account/create-certificates/create-a-certificate-signing-request

这里要注意 Apple Pay Paymetn Processing Certificate的CSR要选择 ECC 和 256 位密钥对

• AppID关联Merchant IDS

1. 在证书中心关联

   
   
   WX20240518-163431@2x.png
   
   

   点击Edit选择上面创建的MerchantID

2. 在Xcode中关联

   点击+Capability在列表中选择ApplePay，再勾选对应的MerchantID

二. 沙盒账号

官方文档

https://developer.apple.com/help/app-store-connect/test-in-app-purchases/create-sandbox-apple-ids/
需要注意的是沙盒AppleID，需要一个未注册过的真实邮箱地址，后续手机登录沙盒账号的时候，要在该邮箱地址去认证

三. 沙盒测试卡号

官方文档

https://developer.apple.com/apple-pay/sandbox-testing/
手机打开开发者模式，[设置-隐私与安全性-下拉到底部打开开发者模式],退出自己的AppleID，登录上面创建的沙盒账号，并完成提示的验证。去钱包中绑定上面文档给定的沙盒测试卡号，有些卡号绑定时会提示类似超出绑定数量，换其它卡号试试。

四. 代码实现

import PassKit

if PKPaymentAuthorizationController.canMakePayments() {
    //设备支持ApplePay
    let paymentRequest = PKPaymentRequest()

    paymentRequest.merchantIdentifier = "merchant.appleApy.demo"
    let currentLocale = Locale.current
    if let countryCode = currentLocale.regionCode {
        paymentRequest.countryCode = countryCode
    }

    if let currencyCode = currentLocale.currencyCode {
        paymentRequest.currencyCode = currencyCode
    }

    var supportedNetworks: [PKPaymentNetwork] =  [
        .amex, .cartesBancaires, .chinaUnionPay, .discover,
        .eftpos, .electron, .elo, .idCredit, .interac,
        .JCB, .mada, .maestro, .masterCard, .privateLabel,
        .quicPay, .suica, .visa, .vPay]
    if #available(iOS 14.5, *) {
        supportedNetworks.append(PKPaymentNetwork.mir)
    }

    if #available(iOS 15.1, *) {
        supportedNetworks.append(PKPaymentNetwork.dankort)
    }

    if #available(iOS 16.0, *) {
        supportedNetworks.append(PKPaymentNetwork.bancontact)
    }

    paymentRequest.supportedNetworks = supportedNetworks
    paymentRequest.merchantCapabilities = [.capability3DS, .emv, .debit, .credit]
    paymentRequest.paymentSummaryItems = [
        PKPaymentSummaryItem(label: "商品", amount: NSDecimalNumber(string: "10.00")),
        PKPaymentSummaryItem(label: "总额", amount: NSDecimalNumber(string: "10.00"))
    ]

    let paymentController = PKPaymentAuthorizationController(paymentRequest: paymentRequest)
    paymentController.delegate = self
    paymentController.present(completion: nil)
} else {
    //设备不支持ApplePay
}

PKPaymentAuthorizationController.canMakePayments()

判断当前设备是否支持ApplePay

paymentRequest.merchantIdentifier = "merchant.appleApy.demo"

替换成自己的merchatID

let currentLocale = Locale.current
if let countryCode = currentLocale.regionCode {
    paymentRequest.countryCode = countryCode
}

if let currencyCode = currentLocale.currencyCode {
    paymentRequest.currencyCode = currencyCode
}

获取当前的国家码，结算单位 (eg: CN/CNY)，也可以写死成美元或人民币

var supportedNetworks: [PKPaymentNetwork] =  [
    .amex, .cartesBancaires, .chinaUnionPay, .discover,
    .eftpos, .electron, .elo, .idCredit, .interac,
    .JCB, .mada, .maestro, .masterCard, .privateLabel,
    .quicPay, .suica, .visa, .vPay]

指定支持的支付网络，罗列齐全即可

paymentRequest.merchantCapabilities = [.capability3DS, .emv, .debit, .credit]

用于指定商户支持的支付功能，.debit借记卡，.credit信用卡，不添加的话，会出现支付失败的情况

paymentRequest.paymentSummaryItems = [
    PKPaymentSummaryItem(label: "商品", amount: NSDecimalNumber(string: "10.00")),
    PKPaymentSummaryItem(label: "总额", amount: NSDecimalNumber(string: "10.00"))
]

商品的结算信息

四. 注意事项

1. 沙盒账号需要真实的邮箱，手机登录沙盒账号时，需要发送验证邮件
2. 沙盒账号的地区和沙盒钱包添加的卡要对应，例如中国区的沙盒账号，对应中国区卡号，创建沙盒账号的时候会有对应的地区选择
3. paymentRequest.merchantCapabilities记得添加.debit, .credit，支持信用卡和借记卡支持，要不然会出现无法支付的情况
