我是 swift 新手，谁能帮我在 swift 中集成 PayU Money.... 我正在使用这个sdk：https://github.com/payu-intrepos/Documentations/wiki/8.1-NEW-iOS-Seamless-SDK-integration

【问题讨论】：

我完全理解开始新事物可能会令人生畏，但最好的学习方式就是实践！您应该先阅读说明并自行尝试。您可能会遇到困难，但这是学习过程的一部分。当您遇到代码的特定问题时，社区将在这里为您提供帮助。祝你好运，你可以做到！

【解决方案1】：

这个答案取自 PayU 文档本身，我在这里回答只是因为我花了几个小时来实施他们的文档。

您好，我可以指导您进行非无缝集成。 https://github.com/payu-intrepos/Documentations/wiki/8.-iOS-SDK-integration#nonseamless

在非无缝集成中，PayU 已经提供 UI 并将处理卡类型和所有付款流程，最后您将收到有关交易状态的通知，并告知失败原因和所有详细信息。

从这里下载 SDK：https://github.com/payu-intrepos/iOS-SDK-Sample-App/archive/3.8.1.zip

来自“BusinessLayer”文件夹中的示例代码复制文件。

所以我希望您现在拥有所有必需的文件，我们可以进一步进行集成。

您正在将 PayU 与 swift 集成，因为 PayU 团队没有提供 swift SDK，因此我们必须继续进行与 Objective-C 的结合。你可以在这里找到：How to call Objective-C code from Swift

在构建设置中创建并配置头文件后，导入以下 SDK 头文件

#import "PayU_iOS_CoreSDK.h"
#import <CommonCrypto/CommonHMAC.h>
#import "PUUIPaymentOptionVC.h"
#import "PUSAWSManager.h"
#import "PUSAWSManager.h"
#import "PUSAHelperClass.h"

现在我们已经准备好在我们的环境/项目中使用 PayU SDK。

创建用于支付的 3 个主要对象的新实例 1)支付参数 2）哈希值 2)Helperclass//计算hash值

将此粘贴到您的 viewDidLoad() 上方

let paymentParam: PayUModelPaymentParams  = PayUModelPaymentParams()
var hashes :PayUModelHashes  = PayUModelHashes()
let PUSAhelper:PUSAHelperClass = PUSAHelperClass()

这是我为进一步处理而创建的函数

func continueWithCardPayment()  {

        paymentParam.key = "gtKFFx"
        paymentParam.transactionID = "umangtxn123"
        paymentParam.amount = "100.0"
        paymentParam.productInfo = "Nokia"
        paymentParam.SURL = "https://google.com/"
        paymentParam.FURL = "https://facebook.com/"
        paymentParam.firstName = "Umang"
        paymentParam.email = "umangarya336@gmail.com"
        paymentParam.environment = ENVIRONMENT_MOBILETEST
        paymentParam.udf1 = "udf1"
        paymentParam.udf2 = "udf2"
        paymentParam.udf3 = "udf3"
        paymentParam.udf4 = "udf4"
        paymentParam.udf5 = "udf5"
        paymentParam.offerKey = ""              // Set this property if you want to give offer:
        paymentParam.userCredentials = ""

        PUSAhelper.generateHashFromServer(self.paymentParam) { (hashes, errorString) in
            self.hashes = hashes
            self.paymentParam.hashes = hashes
            self.callPaymentGateway()
        }
    }

    func callPaymentGateway()  {

        let webServiceResponse :PayUWebServiceResponse = PayUWebServiceResponse()

        webServiceResponse.getPayUPaymentRelatedDetailForMobileSDK(paymentParam) { (paymentDetail, errString, extraParam) in

            if errString == nil {

                let payOptionVC: PUUIPaymentOptionVC = loadVC("PUUIMainStoryBoard", strVCId: VC_IDENTIFIER_PAYMENT_OPTION) as! PUUIPaymentOptionVC

                payOptionVC.paymentParam = self.paymentParam
                payOptionVC.paymentRelatedDetail = paymentDetail

                runOnMainThread({
                    NSNotificationCenter.defaultCenter().addObserver(self, selector: #selector(self.paymentResponseReceived(_:)), name: kPUUINotiPaymentResponse, object: nil)
                    self.navigationController?.pushViewController(payOptionVC, animated: true)
                })
            }
            else{
                print("Failed to proceed for payment : \(errString)")
            }
        }
    }

有一些我的自定义功能会在您复制粘贴时出现错误，我在这里提到它们。照顾好他们

1)loadVC("PUUIMainStoryBoard", strVCId: VC_IDENTIFIER_PAYMENT_OPTION) //我创建的加载视图控制器的Loadvc函数，你必须在调用视图控制器时更改它

2)runOnMainThread({ // 该函数用于在主线程上运行代码。

我已使用 PayU 团队提供的所有测试凭证您可以在他们的文档中找到更多信息：https://www.payumoney.com/pdf/PayUMoney-Technical-Integration-Document.pdf

NSNotificationCenter.defaultCenter().addObserver(self, selector: #selector(self.paymentResponseReceived(_:)), name: kPUUINotiPaymentResponse, object: nil)

//通过这一行，我们添加了支付网关发送的通知，以通知我们支付过程的状态，让我们兑现通知。

func paymentResponseReceived(notify:NSNotification) {
print(notify)
}

您将在 notify.object 中获得响应。您可以在他们的文档中找到更复杂的语言和方式：https://github.com/payu-intrepos/Documentations/wiki/8.-iOS-SDK-integration。

希望这个答案对你有所帮助。

【讨论】：

嘿@Dev_Tandel，我应该将整个 PayU 文件夹从示例应用复制到我的代码吗？
@NikhilManapure - PayU 现在已经发布了用于 swift 的 SDK，请检查一下。
我需要一个非无缝api，我不需要使用自己的api，我猜PayU在swift中只有无缝api，如果我错了，请纠正我。检查here
@NikhilManapure - 是的，他们刚刚为无缝 API 提供了 Swift SDK，对于非无缝 API，您需要复制以下文件夹 1.BusinessLayer 2.CB 3.SDK 4.SDKUI
我有一个由后端团队创建的 api，用于从服务器获取哈希，所以我想我不需要“BusinessLayer”内容，而我很困惑的另一件事是我真的需要“CB”

【解决方案2】：

这是解决方案将工作的源代码，包括所有步骤

首先从此链接下载框架并按照安装步骤进行操作

https://developer.payumoney.com/ios/

完成框架的安装步骤后，这里是代码

导入这个框架

1) 导入 PlugNPlay 2) 导入 CommonCrypto

添加此函数并在您需要 ex 的地方调用它，例如按钮或特定事件

func continueWithCardPayment()

    {
             var paymentParam = PUMTxnParam()
            paymentParam.key = "your merhcant key"
            paymentParam.merchantid = " merchant id"
            paymentParam.txnID = "xyz"
            paymentParam.phone = "982412345"
            paymentParam.amount = "500"
            paymentParam.productInfo = "Nokia"
            paymentParam.surl = "https://test.payumoney.com/mobileapp/payumoney/success.php"
            paymentParam.furl = "https://test.payumoney.com/mobileapp/payumoney/failure.php"
            paymentParam.firstname = "john"
            paymentParam.email = "john@john.com"
            paymentParam.environment = PUMEnvironment.test
            paymentParam.udf1 = "udf1"
            paymentParam.udf2 = "udf2"
            paymentParam.udf3 = "udf3"
            paymentParam.udf4 = "udf4"
            paymentParam.udf5 = "udf5"
            paymentParam.udf6 = ""
            paymentParam.udf7 = ""
            paymentParam.udf8 = ""
            paymentParam.udf9 = ""
            paymentParam.udf10 = ""
            paymentParam.hashValue = self.getHashForPaymentParams(paymentParam)
           // paymentParam.offerKey = ""              // Set this property if you want to give offer:
           // paymentParam.userCredentials = ""



                PlugNPlay.presentPaymentViewController(withTxnParams: paymentParam, on: self, withCompletionBlock: { paymentResponse, error, extraParam in
                    if error != nil {
                        UIUtility.toastMessage(onScreen: error?.localizedDescription)
                    } else {
                        var message = ""
                        if paymentResponse?["result"] != nil && (paymentResponse?["result"] is [AnyHashable : Any]) {
                            print(paymentResponse!)
                            message = "Hello Asad sucess"
                            //                    message = paymentResponse?["result"]?["error_Message"] as? String ?? ""
                            //                    if message.isEqual(NSNull()) || message.count == 0 || (message == "No Error") {
                            //                        message = paymentResponse?["result"]?["status"] as? String ?? ""
                            //                    }
                        } else {
                            message = paymentResponse?["status"] as? String ?? ""
                        }
                        UIUtility.toastMessage(onScreen: message)
                    }
                })

            //PlugNPlay.presentPaymentViewController(withTxnParams: paymentParam, on: self, withCompletionBlock: )
        }

比添加这两个生成哈希和SHA512的功能

func sha512(_ str: String) -> String {

        let data = str.data(using:.utf8)!
        var digest = [UInt8](repeating: 0, count: Int(CC_SHA512_DIGEST_LENGTH))
        data.withUnsafeBytes({
            _ = CC_SHA512($0, CC_LONG(data.count), &digest)
        })
        return digest.map({ String(format: "%02hhx", $0) }).joined(separator: "")
    }
    func getHashForPaymentParams(_ txnParam: PUMTxnParam?) -> String? {
        let salt = "your salt key"
        var hashSequence: String? = nil
        if let key = txnParam?.key, let txnID = txnParam?.txnID, let amount = txnParam?.amount, let productInfo = txnParam?.productInfo, let firstname = txnParam?.firstname, let email = txnParam?.email, let udf1 = txnParam?.udf1, let udf2 = txnParam?.udf2, let udf3 = txnParam?.udf3, let udf4 = txnParam?.udf4, let udf5 = txnParam?.udf5, let udf6 = txnParam?.udf6, let udf7 = txnParam?.udf7, let udf8 = txnParam?.udf8, let udf9 = txnParam?.udf9, let udf10 = txnParam?.udf10 {
            hashSequence = "\(key)|\(txnID)|\(amount)|\(productInfo)|\(firstname)|\(email)|\(udf1)|\(udf2)|\(udf3)|\(udf4)|\(udf5)|\(udf6)|\(udf7)|\(udf8)|\(udf9)|\(udf10)|\(salt)"
        }



        let hash = self.sha512(hashSequence!).description.replacingOccurrences(of: "<", with: "").replacingOccurrences(of: ">", with: "").replacingOccurrences(of: " ", with: "")

        return hash
    }
