php - 安全错误。在 php 中使用 ccavenue 检测到非法访问

Question

我已成功重定向到 ccavenue 支付网关，但在单击取消按钮时，它在重定向 URL 页面中显示错误 “安全错误。检测到非法访问”。

这是我的重定向页面:

<?php include('Aes.php');include('adler32.php')?>
<?php
 $workingKey='myWorkingKey';        //Working Key should be provided here.
 $encResponse=$_POST["encResponse"];    //This is the response sent by the CCAvenue Server


$rcvdString=decrypt($encResponse,$workingKey);      
$AuthDesc="";
$MerchantId="";
$OrderId="";
$Amount=0;
$Checksum=0;
$veriChecksum=false;

$decryptValues=explode('&', $rcvdString);
$dataSize=sizeof($decryptValues);

echo "<center>";


for($i = 0; $i < $dataSize; $i++) 
{
    $information=explode('=',$decryptValues[$i]);
    if($i==0)   $MerchantId=$information[1];    
    if($i==1)   $OrderId=$information[1];
    if($i==2)   $Amount=$information[1];    
    if($i==3)   $AuthDesc=$information[1];
    if($i==4)   $Checksum=$information[1];  
}

$rcvdString=$MerchantId.'|'.$OrderId.'|'.$Amount.'|'.$AuthDesc.'|'.$workingKey;
$veriChecksum=verifyChecksum(genchecksum($rcvdString), $Checksum);

if($veriChecksum==TRUE && $AuthDesc==="Y")
{
    echo "<br>Thank you for shopping with us. Your credit card has been charged and your transaction is successful. We will be shipping your order to you soon.";

}
else if($veriChecksum==TRUE && $AuthDesc==="B")
{
    echo "<br>Thank you for shopping with us.We will keep you posted regarding the status of your order through e-mail";


}
else if($veriChecksum==TRUE && $AuthDesc==="N")
{
    echo "<br>Thank you for shopping with us.However,the transaction has been declined.";

}
else
{
    echo "<br>Security Error. Illegal access detected";

}


echo "<br><br>";

echo "<table cellspacing=4 cellpadding=4>";
for($i = 0; $i < $dataSize; $i++) 
{
    $information=explode('=',$decryptValues[$i]);
        echo '<tr><td>'.$information[0].'</td><td>'.$information[1].'</td></tr>';
}

echo "</table><br>";
echo "</center>";
?>

我用谷歌搜索了这个问题，但没有得到任何解决方案。如何解决这个错误..请给出一些关于相同的建议？

我从文档(可能已经过时但我找不到更新的文档)中发现您需要传递一个名为 cancel_url 的参数，如果客户取消账单页面上的交易。

因此，在您创建付款的页面中，您需要向表单中添加如下内容

<input type="hidden" id="cancel_url" name="cancel_url" value="the_url_where_you_will_proccess_canceled_orders">

您必须已经有类似 redirect_url 的内容
