如何进行nativescript paytm集成

Question

我检查了native-script-paytm集成插件。但是两个git-hub存储库都没有运行，而是给出了堆栈异常。所以我创建了我自己的项目，以及它是如何做一些事情的。但在这里，我有很多关于如何获得'mid'，'order id‘等的问题。

有没有人能一步一步地详细说明这一点。

const createViewModel = require("./main-view-model").createViewModel;
const Paytm = require("@nstudio/nativescript-paytm").Paytm;
const paytm = new Paytm();

exports.pageLoaded = function (args) {
    const page = args.object;
    page.bindingContext = createViewModel();
}


exports.onPayWithPaytm = function (args) {
    console.log("Paying");

    paytm.setIOSCallbacks({
        didFinishedResponse: function (response) {
            console.log("got response");
            console.log(response);
        },
        didCancelTransaction: function () {
            console.log("User cancelled transaction");
        },
        errorMissingParameterError: function (error) {
            console.log(error);
        }
    });

    const order = {
        // This will fail saying duplicate order id
        // generate your own order to test this.
        MID: "Tomcas09769922377481",
        ORDER_ID: "ORDER8874",
        CUST_ID: "CUST6483",
        INDUSTRY_TYPE_ID: "Retail",
        CHANNEL_ID: "WAP",
        TXN_AMOUNT: "10.00",
        WEBSITE: "APP_STAGING",
        CALLBACK_URL: "https://pguat.paytm.com/paytmchecksum/paytmCallback.jsp",
        CHECKSUMHASH:
            "NDspZhvSHbq44K3A9Y4daf9En3l2Ndu9fmOdLG+bIwugQ6682Q3JiNprqmhiWAgGUnNcxta3LT2Vtk3EPwDww8o87A8tyn7/jAS2UAS9m+c="
    };

    paytm.createOrder(order);

    paytm.initialize("STAGING");

    paytm.startPaymentTransaction({
        someUIErrorOccurred: function (inErrorMessage) {
            console.log(inErrorMessage);
        },
        onTransactionResponse: function (inResponse) {
            console.log(inResponse);
        },
        networkNotAvailable: function () {
            console.log("Network not available");
        },
        clientAuthenticationFailed: function (inErrorMessage) {
            console.log(inErrorMessage);
        },
        onErrorLoadingWebPage: function (
            iniErrorCode,
            inErrorMessage,
            inFailingUrl
        ) {
            console.log(iniErrorCode, inErrorMessage, inFailingUrl);
        },
        onBackPressedCancelTransaction: function () {
            console.log("User cancelled transaction by pressing back button");
        },
        onTransactionCancel: function (inErrorMessage, inResponse) {
            console.log(inErrorMessage, inResponse);
        }
    });
}

正如插件的ReadMe文件中所提到的，

你将需要一个工作的backend server来生成paytm订单。不要在应用程序中生成订单或校验和。
