Order_id在iOS swift4中的Paytm集成中无效 [英] Order_id is invalid in Paytm Integration in iOS swift4

问题描述

swift4中的Paytm集成: 响应为交易完成，响应消息为无效的订单ID ，但是我在每次交易中都生成新的订单ID，是否有任何可能的解决方案. 我要传递的参数:

Paytm Integration in swift4: The response is Transaction Finished and the response message is Invalid order id but I'm generating order id new at every transaction, is there any possible solution for this. Parameter which I'm passing :

    var orderID = "123456789".randomString(length: 20)
    orderDict["MID"] = "RentSe98692194807190"
    orderDict["CHANNEL_ID"] = "WAP"
    orderDict["INDUSTRY_TYPE_ID"] = "Retail"
    orderDict["WEBSITE"] = "APP_STAGING"
    orderDict["TXN_AMOUNT"] = "100"
    orderDict["ORDER_ID"] = orderID
    orderDict["CHECKSUMHASH"] = checksumHash
    orderDict["CUST_ID"] = "240"
    orderDict["EMAIL"] = "[e-mail]" as AnyObject
    orderDict["MOBILE_NO"] = "7777777777" as AnyObject
    orderDict["REQUEST_TYPE"] = "DEFAULT" as AnyObject
    orderDict["THEME"] = "merchant" as AnyObject
    orderDict["CALLBACK_URL"] = "https://pguat.paytm.com/paytmchecksum/paytmCallback.jsp" as AnyObject

推荐答案

    //MARK:- Create Payment

func createPayment(checksumHash : String, orderID : String) {

    var custID = ""
    var orderID = String()

    custID =  custID.randomString(length: 20)
    print(custID)

    var orderDict = [AnyHashable : Any]()

    let txnAmt = ((self.amountTextField.text) ?? "0")
    print(txnAmt)

    orderDict["MID"] = "RentSe98692194807190"
    orderDict["CHANNEL_ID"] = "WAP"
    orderDict["INDUSTRY_TYPE_ID"] = "Retail"
    orderDict["WEBSITE"] = "APP_STAGING"
    orderDict["TXN_AMOUNT"] = txnAmt as AnyObject
    orderDict["ORDER_ID"] = orderID
    orderDict["CHECKSUMHASH"] = checksumHash
    orderDict["CUST_ID"] = custID
    orderDict["EMAIL"] = "[e-mail]" as AnyObject
    orderDict["MOBILE_NO"] = "7777777777" as AnyObject
    orderDict["REQUEST_TYPE"] = "DEFAULT" as AnyObject
    orderDict["THEME"] = "merchant" as AnyObject
    orderDict["CALLBACK_URL"] = "https://pguat.paytm.com/paytmchecksum/paytmCallback.jsp" as AnyObject

    print(custID)
    let pgOrder = PGOrder(params: orderDict)

    let transaction = PGTransactionViewController.init(transactionFor: pgOrder)
    if eServerTypeStaging != eServerTypeNone {

        transaction!.serverType = eServerTypeStaging
        transaction!.merchant = merchant
        transaction!.delegate = self
        self.present(transaction!, animated: true, completion: {

        })
    }
}`
