PayTm All-in-one Sdk - 支付成功后出现网页不可用等错误 - 回调 url 错误

Question

完整的错误信息是： 无法加载https://merchant.com/callback 的网页，因为：net::ERR_CONNECTION_TIME_OUT

我的启动 paytm 的代码并在应用调用中得到同样的错误：

 private void startPayTMCall(InitiateAPIResponse apiResponse, PaytmInitRequestBody paytmInitRequestBody) {
        String orderIdString = paytmInitRequestBody.getOrderId();
        String MID = getString(R.string.MID);
        String amount = String.valueOf(paytmInitRequestBody.getAmount());

/*
        On completion of transaction, Paytm payment gateway will send the response on this URL. This can be a static response URL as mentioned below:
        Staging Environment: "https://securegw-stage.paytm.in/theia/paytmCallback?ORDER_ID=<order_id>"
        Production Environment: "https://securegw.paytm.in/theia/paytmCallback?ORDER_ID=<order_id>"*/
        // for test mode use it
        // String host = "https://securegw-stage.paytm.in/";
        // for production mode use it
        String host = "https://securegw.paytm.in/";
        String callBackUrl = host + "theia/paytmCallback?ORDER_ID=" + orderIdString;


        PaytmOrder order = new PaytmOrder(orderIdString, MID, apiResponse.getBody().getTxnToken(), amount, callBackUrl);

                            TransactionManager transactionManager = new TransactionManager(order, new PaytmPaymentTransactionCallback() {
                    @Override
                    public void onTransactionResponse(Bundle bundle) {
                        Toast.makeText(getApplicationContext(), "Payment Transaction response " + bundle.toString(), Toast.LENGTH_LONG).show();
                    }

                    @Override
                    public void networkNotAvailable() {
                        Toast.makeText(MainActivity.this, "networkNotAvailable", Toast.LENGTH_SHORT).show();
                    }

                    @Override
                    public void onErrorProceed(String s) {
                        Toast.makeText(MainActivity.this, "onErrorProceed "+s, Toast.LENGTH_SHORT).show();
                    }

                    @Override
                    public void clientAuthenticationFailed(String s) {
                        Toast.makeText(MainActivity.this, "clientAuthenticationFailed : "+s, Toast.LENGTH_SHORT).show();
                    }

                    @Override
                    public void someUIErrorOccurred(String s) {
                        Toast.makeText(MainActivity.this, "someUIErrorOccurred : "+s, Toast.LENGTH_SHORT).show();

                    }

                    @Override
                    public void onErrorLoadingWebPage(int i, String s, String s1) {
                        Toast.makeText(MainActivity.this, "onErrorLoadingWebPage : "+s+" : "+s1, Toast.LENGTH_SHORT).show();

                    }

                    @Override
                    public void onBackPressedCancelTransaction() {
                        Toast.makeText(MainActivity.this, "onBackPressedCancelTransaction : ", Toast.LENGTH_SHORT).show();

                    }

                    @Override
                    public void onTransactionCancel(String s, Bundle bundle) {
                        Toast.makeText(MainActivity.this, "onTransactionCancel : "+s, Toast.LENGTH_SHORT).show();

                    }
                });


        transactionManager.setAppInvokeEnabled(false);
        transactionManager.setEnableAssist(true);
        transactionManager.startTransaction(this, REQ_CODE_ORDER);

    }

我认为回调 url 有问题，可能会被磨损，但我遵循 paytm 官方多合一 SDK 文档。 https://developer.paytm.com/docs/all-in-one-sdk/

请在“Initiate Transaction API”的“callbackUrl”请求参数中使用 Paytm 静态回调 URL。提到的 URL (merchant.com/callback) 只是一个示例，您可以使用自定义的回调 URL 或使用下面提到的回调 URL。
