安全错误.在php中使用ccavenue检测到非法访问

我成功地重定向到ccavenue支付网关但是在点击取消按钮时,它在重定向网页中显示错误“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>";
?>

我搜索了这个问题,但无法得到任何解决方案.如何解决这个错误..请给出一些相同的建议？

解决方法:

我从文档中发现(可能已经过时但我找不到更新的文档)您需要传递一个名为cancel_url的参数,如果客户在结算页面上取消了该交易,CCAvenue会将客户重定向到此URL.

因此,在您创建付款的页面中,您需要向表单添加类似的内容

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

您必须已经拥有与redirect_url类似的东西
