Javascript 挑战流量3d安全2.NET SDK

我几乎已经完成了3d Secure 2工作流（）的实现，但我正在努力确定如何处理挑战流程

除了挑战流程卡之外，所有的卡都可以工作，我得到的iFrame显示在我的端部，单击“继续”将触发对我的挑战URL的请求-我正在执行API文档（上面链接）上显示的代码，但是我返回的JSON只是显示在iFrame中，而不是触发我的javascript。请在下面找到我的JS和我的挑战流程端点：

async function performPaymentFlow(type, cardDetails, personalDetails, orderID) {
    
    // Perform the check card on the information sent in
    var versionCheckData, authenticationData;
    try {
        // call the api to see whether the card is valid
        versionCheckData = await checkVersion('/api/Payments/CheckCard', { cardNumber: cardDetails.cardNumber });
        if (versionCheckData.IsError) {
            // show user error
        }

    }
    catch (e) {
        // show user error
    }

    // perform authentication
    // WITHIN THIS CALL THIS IS WHERE THE CHALLENGE IS SHOWN TO THE USER
    try {
        authenticationData = await initiateAuthentication('/api/Payments/Authenticate', {
            serverTransactionId: versionCheckData.serverTransactionId,
            methodUrlComplete: true,
            card: {
                expiryMonth: cardDetails.expiryMonth,
                expiryYear: cardDetails.expiryYear,
                securityCode: cardDetails.cv2,
                cardHolderName: cardDetails.cardName,
                cardNumber: cardDetails.cardNumber
            },
            challengeWindow: {
                displayMode: 'lightbox',
            },
            screenOptions: {
                colorDepth: screen.colorDepth,
                language: navigator.language,
                timezone: new Date().getTimezoneOffset()
            },
            personalDetails: personalDetails,
            type: type,
            orderID: orderID
        });

        if (authenticationData.IsError) {
            // show user error
        }
        else {
            // frictionless authentication success and authorization success
            if (authenticationData.result == "AUTHORIZATION_SUCCESS") {
                // complete
            }
            // challenge success
            else if (authenticationData.challenge.response.data.transStatus == "Y") {
            
                var serverTransactionId = authenticationData.challenge.response.data.threeDSServerTransID;

                var model = {
                    serverTransactionId: serverTransactionId,
                    card: cardDetails,
                    type: type
                };
                $.ajax({
                    type: "POST",
                    url: "/api/Booking/Authorize",
                    contentType: "application/json; charset=utf-8",
                    dataType: "json",
                    data: JSON.stringify({ "model": model })
                }).done(function (authorizationResponse) {
                    if (authorizationResponse.IsError) {
                        // Show user errlr
                    }
                    else {
                       // complete
                    }
                });
            }

            // challenge failure
            else {
                // show user error
            }
        }
    }
    catch (e) {
        // show user error
    }
};

下面是我的挑战URL的服务器端实现

public void Challenge()
        {
            // Get the data from the form
            var cres = HttpContext.Current.Request.Form["cres"];
            try
            {
                #region Instantiate the service
                ServicesContainer.ConfigureService(new GpEcomConfig
                {
                    MerchantId = Constants.realexuser,
                    AccountId = "internet",
                    SharedSecret = Constants.realexsecret,
                    MethodNotificationUrl = Constants.DomainName + "/api/Payments/MethodSetup",
                    ChallengeNotificationUrl = Constants.DomainName + "/api/Payments/Challenge",
                    MerchantContactUrl = Constants.DomainName + "/visit/find-us-and-faqs",
                    Secure3dVersion = Secure3dVersion.Two
                });
                #endregion

                #region data population and parsing
                byte[] data = Convert.FromBase64String(cres.Replace('-', '+').Replace('_', '/').PadRight(4 * ((cres.Length + 3) / 4), '='));

                string challengeUrlResponseString = Encoding.UTF8.GetString(data);

                dynamic challengeUrlResponse = JsonConvert.DeserializeObject(challengeUrlResponseString);

                var threeDSServerTransID = challengeUrlResponse.threeDSServerTransID; // af65c369-59b9-4f8d-b2f6-7d7d5f5c69d5
                var acsTransId = challengeUrlResponse.acsTransID; // 13c701a3-5a88-4c45-89e9-ef65e50a8bf9
                var messageType = challengeUrlResponse.messageType; // Cres
                var messageVersion = challengeUrlResponse.messageVersion; // 2.1.0
                var transStatus = challengeUrlResponse.transStatus; // Y
                #endregion

                // Package up the data and send it back to the user
                challengeUrlResponseString = JsonConvert.SerializeObject(new
                {
                    threeDSServerTransID = threeDSServerTransID,
                    transStatus = transStatus
                });
                SendResponse(challengeUrlResponseString);
                return;
            }
            // Uh oh - another error from the API
            catch (Exception exce)
            {
                // Return error to user
            }
        }

由此返回的JSON显示在iframe中，而不是返回到我的JS以便我可以继续在流程中，任何帮助都将不胜感激。

需要通知客户端该质询步骤已完成。为此，质询通知端点应响应：

<script src="globalpayments-3dsecure.js"></script>
<script>
    GlobalPayments.ThreeDSecure.handleChallengeNotification('"threeDSServerTransID":"threeDSServerTransID","transStatus":"transStatus"');
</script>

GlobalPayments.ThreeDSecure.handleChallengeNotification（“'ThreedServerTransId:“ThreedServerTransId”，“transStatus:“transStatus”）；

请确保包含3DS JS库
