由于success.php中有一个代码，它比较发送给PayUMoney的$hash变量与我们接收的变量的相等性，如果它们不相等，则显示消息：
无效事务。请重试
所以我收到了这个消息，我不知道如何解决这个问题。
这里有一些成功的示例代码。php
<?php
$status=$_POST["status"];
$firstname=$_POST["firstname"];
$amount=$_POST["amount"];
$txnid=$_POST["txnid"];
$posted_hash=$_POST["hash"];
$key=$_POST["key"];
$productinfo=$_POST["productinfo"];
$email=$_POST["email"];
$salt="salt";
if (isset($_POST["additionalCharges"])) {
$additionalCharges=$_POST["additionalCharges"];
$retHashSeq = $additionalCharges.'|'.$salt.'|'.$status.'|||||||||||'.$email.'|'.$firstname.'|'.$productinfo.'|'.$amount.'|'.$txnid.'|'.$key;
}
else {
$retHashSeq = $salt.'|'.$status.'|||||||||||'.$email.'|'.$firstname.'|'.$productinfo.'|'.$amount.'|'.$txnid.'|'.$key;
}
$hash = hash("sha512", $retHashSeq);
if ($hash != $posted_hash) {
echo "Invalid Transaction. Please try again";
}
else {
echo "<h3>Thank You. Your order status is ". $status .".</h3>";
echo "<h4>Your Transaction ID for this transaction is ".$txnid.". </h4>";
echo "<h4>We have received a payment of Rs. " . $amount . ". Your order will soon be shipped.</h4>";
}
?>
第10行。$salt="salt"；
它应该是$salt="您的盐从您的payumoney帐户enter code here">
示例
$status=$_POST["status"];
$firstname=$_POST["firstname"];
$amount=$_POST["amount"];
$txnid=$_POST["txnid"];
$posted_hash=$_POST["hash"];
$key=$_POST["key"];
$productinfo=$_POST["productinfo"];
$email=$_POST["email"];
$salt="GQs7yium";
这就是$retHastseq不等于$posted_hash的原因。
试试看。
