所有的教程我都查过了，在网关集成方面也做了很多研发。 但是没有找到集成paytm支付网关的方法。

func paymentConfiguration()
{
    var orderDict = [AnyHashable: Any]()
    orderDict["MID"] = "WorldP64425807474247"
    orderDict["CHANNEL_ID"] = "WAP"
    orderDict["INDUSTRY_TYPE_ID"] = "Retail"
    orderDict["WEBSITE"] = "worldpressplg"
    orderDict["TXN_AMOUNT"] = "1"
    orderDict["ORDER_ID"] = ViewController.generateOrderID(withPrefix: "")
    orderDict["CALLBACK_URL"] = "https://securegw.paytm.in/theia/paytmCallback?ORDER_ID=<ORDER_ID>"
    orderDict["CHECKSUMHASH"] = "w2QDRMgp1/BNdEnJEAPCIOmNgQvsi+BhpqijfM9KvFfRiPmGSt3Ddzw+oTaGCLneJwxFFq5mqTMwJXdQE2EzK4px2xruDqKZjHupz9yXev4="
    orderDict["REQUEST_TYPE"] = "DEFAULT"
    orderDict["CUST_ID"] = "1234567890"
    var order = PGOrder(params: orderDict)
}



func openPaytmController()
{
    PGServerEnvironment.selectServerDialog(view, completionHandler: {(_ type: ServerType) -> Void in
        var txnController = PGTransactionViewController.initTransaction(forOrder: order)
        if type != eServerTypeNone {
            txnController.serverType = type
            txnController.merchant = mc
            txnController.delegate = self
            self.show(txnController)
        }
    })
}

如有任何帮助，我们将不胜感激。 提前致谢

PayTM Integaration with swift with detail

**

##下载支付宝SDK## https://github.com/Paytm-Payments/Paytm_iOS_App_Kit 确保在“Linked binaries and frameworks”中添加了动态库和 systemConfiguration.framwork

将桥接头文件添加到项目中

        #import "PaymentsSDK.h"

您必须生成 CheckSumHash key - 用于交易目的的 PayTm 唯一 key

传递以下参数生成checkSumHash

 let params:[String: Any] = [
            "CUST_ID”:<Your Customer ID>,  // you have to generate unique customer ID (Generate random string - less than 50 length count )
            "TXN_AMOUNT":"10.00", // sample amount
              “MID": <Your merchant ID>, 
             "ORDER_ID”:<Your Order ID>, // you have to generate unique order ID  (Generate random string - less than 50 length count )
             "INDUSTRY_TYPE_ID":"Retail",   //Staging Environment  
              "CHANNEL_ID":"WAP", //Staging Environment  
              "WEBSITE":"APPSTAGING",  //Staging Environment  - Mobile
             "CALLBACK_URL":"https://securegw-stage.paytm.in/theia/paytmCallback?ORDER_ID=\(<Your Order ID>)” // This should be important one and make sure the correct order ID. 
  ]

在您的服务器中，您必须设置应根据给定参数和商户 key 生成 CheckSumHash key 的文件(存储在文件中；不要在您的应用程序中使用)。那应该是您的 CHECKSUM URL 以及上述参数。最后，我们在响应中得到 CheckSumHash

你必须给出上面提到的参数以及 checkSumHash(你得到了响应 - 引用:步骤 3)来模仿 PGTransactionViewCOntroller

       let params:[String: Any] = [
            "CUST_ID”:<Your Customer ID>,  // you have to generate unique customer ID (Generate random string - less than 50 length count )
            "TXN_AMOUNT":"10.00", // sample amount
              “MID": <Your merchant ID>, 
             "ORDER_ID”:<Your Order ID>, // you have to generate unique order ID  (Generate random string - less than 50 length count )
             "INDUSTRY_TYPE_ID":"Retail",   //Staging Environment  
              "CHANNEL_ID":"WAP", //Staging Environment  
              "WEBSITE":"APPSTAGING",  //Staging Environment  - Mobile
             "CALLBACK_URL":"https://securegw-stage.paytm.in/theia/paytmCallback?ORDER_ID=\(<Your Order ID>)”  // This should be important one and make sure the correct order ID. ,“CHECKSUMHASH”:<your geenrated CheckSumHash key> // which you got the response of generate CheckSumHash
]

  let order = PGOrder(params: params)

    let txnController = PGTransactionViewController(transactionFor: order)
    txnController?.serverType = eServerTypeStaging
    txnController?.merchant = PGMerchantConfiguration.default()
    txnController?.merchant.checksumGenerationURL = CheckSumGenerationURL
    txnController?.merchant.merchantID = "FlotaS90100524961231"
    txnController?.merchant.checksumValidationURL = CheckSumVerifyURL + orderID
    txnController?.loggingEnabled = true
    txnController?.merchant.website = "APPSTAGING"
    txnController?.merchant.industryID = "Retail"
    txnController?.serverType = eServerTypeStaging
    txnController?.delegate = self

    self.navigationController?.pushViewController(txnController!, animated: true)

PayTM 委托(delegate)处理响应

func didSucceedTransaction(controller: PGTransactionViewController, response: [NSObject : AnyObject]) {
        print(response)
    }

    func didFinishedResponse(_ controller: PGTransactionViewController!, response responseString: String!) {
        print(responseString) // Response will be in string 
         let data = responseString.data(using: .utf8)!
    let obj = JSON(data: data)
    if obj["STATUS"].stringValue != "TXN_SUCCESS" {
       //handle what you want             
    }
     }
    }
    func didFailTransaction(_ controller: PGTransactionViewController!, error: Error!, response: [AnyHashable : Any]!) {
        print(error)

    }

    func didCancelTrasaction(_ controller: PGTransactionViewController!) {
        print("User camcelled the trasaction")
        controller.navigationController?.popViewController(animated: true)
    }

    func errorMisssingParameter(_ controller: PGTransactionViewController!, error: Error!) {
        print(error.localizedDescription)
        controller.navigationController?.popViewController(animated: true)
    }
