我有一个来自migs的网关,但是他们将md5更改为SHA-256 HMAC如何在我的代码上更改它我尝试了太多次但我发现错误400我觉得我的代码有一些问题
现有代码
<?php
$db1 = new ps_DB();
$q = "SELECT country_2_code FROM #__vm_country WHERE country_3_code='".$user->country."' ORDER BY country_2_code ASC";
$db1->query($q);
$url = "https://migs.mastercard.com.au/vpcpay";
$SECURE_SECRET = MIGS_SS;
$vpcURL = $url . "?";
$md5HashData = $SECURE_SECRET;
$tax_total = $db->f("order_tax") + $db->f("order_shipping_tax");
$discount_total = $db->f("coupon_discount") + $db->f("order_discount");
if( MIGS_TEST == 1)
$amt123 = MIGS_TESTMODEAMT*100;
else
$amt123 = round(($db->f("order_total")+$tax_total-$discount_total)*100,2);
$post_variables = Array(
"vpc_Version" => "1",
"vpc_Command" => "pay",
"vpc_AccessCode" => MIGS_ACCESSCODE,
"vpc_MerchTxnRef" => $db->f("order_id").'_'.$db->f("order_number"),
"vpc_Merchant" => MIGS_MID,
"vpc_OrderInfo" => $VM_LANG->_('PHPSHOP_ORDER_PRINT_PO_NUMBER')."_". $db->f("order_id"),
"vpc_Amount" => $amt123,
"vpc_Locale" => 'en',
"vpc_ReturnURL" => SECUREURL ."index.php?option=com_virtuemart& page=checkout.migs&order_id=".$db->f("order_id")
);
ksort ($post_variables);
if( $page == "checkout.thankyou" ) {
$query_string = "?";
foreach( $post_variables as $name => $value ) {
$query_string .= urlencode($name). "=" . urlencode($value) ."&";
//$vpcURL .= urlencode($name). "=" . urlencode($value) ."&";
$md5HashData .= $value;
}
if (strlen($SECURE_SECRET) > 0) {
$query_string .= "vpc_SecureHash=" . strtoupper(md5($md5HashData));
//$vpcURL .= "vpc_SecureHash=" . strtoupper(md5($md5HashData));
}
//die( $url.' pppppppp '.$query_string);
vmRedirect( $url . $query_string );
} else {
echo '<form action="'.$url.'" method="post" target="_blank">';
echo '<input type="image" name="submit" src="https://www.paypal.com/en_US /i/btn/x-click-but6.gif" alt="Click to pay with PayPal - it is fast, free and secure!" />';
foreach( $post_variables as $name => $value ) {
echo '<input type="hidden" name="'.$name.'" value="'.htmlspecialchars($value).'" />';
}
echo '</form>';
}
?>
我从migs获得的新代码
foreach($_POST as $key => $value) {
// create the hash input and URL leaving out any fields that have no value
if (strlen($value) > 0) {
?>
<input type="hidden" name="<?php echo($key); ?>" value="<?php echo($value); ?>"/><br>
<?php
if ((strlen($value) > 0) && ((substr($key, 0,4)=="vpc_") || (substr($key,0,5) =="user_"))) {
$hashinput .= $key . "=" . $value . "&";
}
}
}
$hashinput = rtrim($hashinput, "&");
?>
<!-- attach SecureHash -->
<input type="hidden" name="vpc_SecureHash" value="<?php echo(strtoupper(hash_hmac('SHA256',
$hashinput, pack('H*',$securesecret)))); ?>"/>
<input type="hidden" name="vpc_SecureHashType" value="SHA256">
我如何在我的代码中使用它?基于md5的代码运行良好,但当我将其转换为sha时400错误是在到达网关后因为安全问题而删除了migs密码

请尝试https://github.com/kareem3d/merchant-sample-code
我在此示例代码中只遇到一个问题, 在https://github.com/kareem3d/merchant-sample-code/blob/master/functions.php中,您需要删除urlencode。
行:$ secureHash。= $ key。“=”。$ value。“&amp;”;

400可能是无效的哈希
你要做的是ascii sort并加入'&amp;'将发出请求的vpc值对(减去vpc_SecureHash和vpc_SecureHashType)。不要对vpc_ReturnURL进行URL编码。将此字符串传递给hmac以创建vpc_SecureHashSecret。编码返回URL并构建您的请求,包括vpc_SecureHash和vpc_SecureHashType
答案 2 :(得分:0)
由于您在适应SHA256之后没有提供您的代码,我无法确定您的问题是什么。但我想这是使用urlencode()
的问题,因为我遇到了同样的问题并通过这种方式修复了它。
