銀聯(lián)控件接入流程:

銀聯(lián)控件接入流程

根據(jù)提供的流程圖滨彻，作為app端搔确，我們需要做的四件事如下：
1.調(diào)用后端的接口傳入?yún)?shù)發(fā)起訂單請(qǐng)求绝页，并接收tn

2.調(diào)銀聯(lián)的startpay方法

startpay

3.實(shí)現(xiàn)UPAPayPluginDelegate的方法民泵，根據(jù)result處理邏輯

回調(diào)處理

以上，就是銀聯(lián)sdk的集成捍壤，在此之前需要去銀聯(lián)官網(wǎng)注冊(cè)登錄完善商戶信息骤视，大概需要兩三個(gè)工作日就好，第6步需要一點(diǎn)時(shí)間白群，但是等就行了尚胞。

銀聯(lián)的集成可以說是非常簡(jiǎn)單的硬霍，下面介紹一下原生iOS支付處理帜慢；

直接上代碼：

// MARK: - applepay原生支付
extension Demo: PKPaymentAuthorizationViewControllerDelegate  {
    
    func payaction(){
        let request = PKPaymentRequest()
        if #available(iOS 9.2, *) {
            request.supportedNetworks = [PKPaymentNetwork.amex, PKPaymentNetwork.masterCard, PKPaymentNetwork.visa, PKPaymentNetwork.chinaUnionPay]
        } else {
            request.supportedNetworks = [PKPaymentNetwork.amex, PKPaymentNetwork.masterCard, PKPaymentNetwork.visa]
        }
        
        if PKPaymentAuthorizationViewController.canMakePayments(usingNetworks: request.supportedNetworks) {
            noticeOnlyText("可以支付，開始建立支付請(qǐng)求")
            
            request.countryCode = "CN"
            request.currencyCode = "CNY"
            request.merchantIdentifier = "merchant.com.xxxx"
            request.merchantCapabilities = PKMerchantCapability.capability3DS
            
            
            let wax = PKPaymentSummaryItem(label: "訂單金額", amount: NSDecimalNumber(string: "\(self.allPrice)"))
            let total = PKPaymentSummaryItem(label: "xxx", amount: wax.amount)
            
            request.paymentSummaryItems = [wax, total]
            
            let vc = PKPaymentAuthorizationViewController(paymentRequest: request)
            vc?.delegate = self
            present(vc!, animated: true, completion: nil)
        }
        else {
            noticeOnlyText("您沒有綁定任何銀行卡或者當(dāng)前設(shè)備不支持ApplePay")
        }
    }
    
    func paymentAuthorizationViewControllerDidFinish(_ controller: PKPaymentAuthorizationViewController) {
        noticeOnlyText("支付結(jié)束")
        dismiss(animated: true, completion: nil)

    }
    
    func paymentAuthorizationViewController(_ controller: PKPaymentAuthorizationViewController, didAuthorizePayment payment: PKPayment, completion: @escaping (PKPaymentAuthorizationStatus) -> Void) {
        // 調(diào)后端接口返回success或者fail
        completion(PKPaymentAuthorizationStatus.success)
        
        //訂單ID 暫時(shí)
        let vc = KeMyTicketVc.init(orderId: "")
        navigationController?.pushViewController(vc, animated: true)
    }
}
