希望您已添加验证校验和所需的“CALLBACK_URL”。正如 paytm 文档中提到的
CALLBACK_URL - 避免篡改的安全参数。使用 Paytm 提供的服务器端校验和实用程序生成。商家必须确保它始终在服务器上生成。
希望这能发挥魔力。

我希望您已将此变量添加到您的代码中 -
PaytmPGService service;
如果您正在使用它,那么您可以获得所有与付款相关的方法,如下所示:
service.startPaymentTransaction(this, true,
true, new PaytmPaymentTransactionCallback() {
@Override
public void onTransactionResponse(Bundle inResponse) {
System.out.println("===== onTransactionResponse " + inResponse.toString());
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
if (Objects.equals(inResponse.getString("STATUS"), "TXN_SUCCESS")) {
// Payment Success
} else if (!inResponse.getBoolean("STATUS")) {
// Payment Failed
}
}
}
@Override
public void networkNotAvailable() {
// network error
}
@Override
public void clientAuthenticationFailed(String inErrorMessage) {
// AuthenticationFailed
}
@Override
public void someUIErrorOccurred(String inErrorMessage) {
// UI Error
}
@Override
public void onErrorLoadingWebPage(int iniErrorCode, String inErrorMessage, String inFailingUrl) {
// Web page loading error
}
@Override
public void onBackPressedCancelTransaction() {
// on cancelling transaction
}
@Override
public void onTransactionCancel(String inErrorMessage, Bundle inResponse) {
// maybe same as onBackPressedCancelTransaction()
}
});
我希望这能帮到您。

将默认的回调 URL 更改为假设“ http://yourdomain(如果在本地主机上检查,则为 IP 地址)/pgResponse.php”;。将以下代码添加到 pgResponse.php
<?php
session_start();
header("Pragma: no-cache");
header("Cache-Control: no-cache");
header("Expires: 0");
// following files need to be included
require_once("./lib/config_paytm.php");
require_once("./lib/encdec_paytm.php");
$paytmChecksum = "";
$paramList = array();
$isValidChecksum = "FALSE";
$paramList = $_POST;
$return_array= $_POST;
$checkSum = getChecksumFromArray($paramList,PAYTM_MERCHANT_KEY);//generate new checksum
$paytmChecksum = isset($_POST["CHECKSUMHASH"]) ? $_POST["CHECKSUMHASH"] : ""; //Sent by Paytm pg
//Verify all parameters received from Paytm pg to your application. Like MID received from paytm pg is same as your applicationís MID, TXN_AMOUNT and ORDER_ID are same as what was sent by you to Paytm PG for initiating transaction etc.
$isValidChecksum = verifychecksum_e($paramList, PAYTM_MERCHANT_KEY, $paytmChecksum); //will return TRUE or FALSE string.
$return_array["IS_CHECKSUM_VALID"] = $isValidChecksum ? "Y" : "N";
unset($return_array["CHECKSUMHASH"]);
$mid = $_POST['MID'];
$orderid = $_POST['ORDERID'];
$curl = curl_init();
curl_setopt_array($curl, array(
CURLOPT_RETURNTRANSFER => 1,
CURLOPT_URL => 'https://securegw-stage.paytm.in/order/status?JsonData={"MID":"'.$mid.'","ORDERID":"'.$orderid.'","CHECKSUMHASH":"'.$checkSum.'"}',
CURLOPT_USERAGENT => 'Make Request'
));
$resp = curl_exec($curl);
$status= json_decode($resp)->STATUS;
//do something in your database
$encoded_json = htmlentities(json_encode($return_array));
?>

在安卓工作室中:
public void onTransactionResponse(Bundle inResponse) {
Log.d("Create Response", inResponse.toString());
String response = inResponse.getString("RESPMSG");
if (response.equals("Txn Successful.")) {
Toast.makeText(Bag.this,"Payment done",Toast.LENGTH_LONG).show();
}
else{
Toast.makeText(Bag.this,response,Toast.LENGTH_LONG).show();
}
}
