将Paytm与swift 3.0集成

Question

我想将paytm支付网关与swift 3.0我集成.我只需按照github 链接.但我有问题["CHECKSUMHASH"]="".我能把这个钥匙放进去.

orderDict["MID"] = strMid
                            orderDict["ORDER_ID"] = strOrderId
                            orderDict["CUST_ID"] = strCustomerId
                            orderDict["INDUSTRY_TYPE_ID"] = strIndustryType
                            orderDict["CHANNEL_ID"] = strChanalID
                            orderDict["TXN_AMOUNT"] = strAmt
                            orderDict["WEBSITE"] = strWebsite
                            orderDict["CALLBACK_URL"] = "http://xxxxx.co.in/verifyChecksum.php"
                    orderDict["CHECKSUMHASH"] = ""

这给了我无效的校验和,请告诉我如何生成校验和.

Answer 1

首先,您可以调用服务器api来生成校验和.如果您正在使用,Almofire那么请致电

var parameters:[String:String]?
        parameters = ["MID":strMid,"ORDER_ID":strOrderId ,"INDUSTRY_TYPE_ID":strIndustryType,"CHANNEL_ID":strChanalID,"TXN_AMOUNT":strAmt,"WEBSITE":strWebsite, "CUST_ID":strCustomerId,"CALLBACK_URL":"http://xxxxxxx.co.in/verifyChecksum.php"]
                    showHud(self.view)
        print(parameters)

        Alamofire.request("http://xxxxxx.co.in/generateChecksum.php", method: .post, parameters: parameters,encoding: URLEncoding.default, headers: nil).responseJSON {}

请通过这个api 全部 parameter.它在下面给出response

{
  "CHECKSUMHASH": "xxxxxxxxxxxxx",
  "ORDER_ID": "xxxxxxxx",
  "payt_STATUS": "1"
}

在这里Dictionary你得到CHECKSUMHASH它通过paytm order.
