//提交给MIGS PAYMENT GATEWAY的值

        $SECURE_SECRET =  $signature; //value from migs payment gateway
        $accessCode    =  $accesscode;//value from migs payment gateway
        $merchantId    =  $merchantid;//value from migs payment gateway
        $paymentdata = array(
                 "vpc_AccessCode" => $accessCode,
                 "vpc_Amount" => ($amount*100),//our product price , must multipy by 100
                 "vpc_Command" => 'pay',
                 "vpc_Locale" => 'en',// order id

                 "vpc_OrderInfo" => "Some Comment",
                 "vpc_ReturnURL" => "htps://yoursite.com/returnpoint",//here code for db updation, return variable here
                 "vpc_Version" => '1'

            // create the md5 input and URL
            if (strlen($value) > 0) {
                // this ensures the first paramter of the URL is preceded by the '?' char
                if ($appendAmp == 0) {
                    $actionurl .= urlencode($key) . '=' . urlencode($value);
                    $str = 1;
                } else {
                    $actionurl .= '&' . urlencode($key) . "=" . urlencode($value);
                }
                $HashData .= $value;
            }
        }
        if (strlen($SECURE_SECRET) > 0){$actionurl .= "&vpc_SecureHash=" . strtoupper(md5($HashData));}
        header("Location: " . $actionurl);
    }

/////////////////////返回值/////////////////////////////////

the return url will be like
https://yoursite.com/returnpoint?vpc_TransactionNo="migs_transaction_number"&vpc_MerchTxnRef="random_unique_value(we post to migs)"&vpc_TxnResponseCode=value&vpc_Message="value"
 if vpc_TxnResponseCode = 0 -- success ,vpc_Message = approved -- paymet is success , All other unsuccessfull payment

实现migs支付网关，我们需要在其中发布一些详细信息到https://migs.mastercard.com.au/vpcpay?这个url包含以下数据

    /*"vpc_AccessCode" the accesscode given by Migs
"vpc_Amount" Amount that is multiplied by 100
"vpc_Command" ='pay',default pay
"vpc_Locale" = 'en' // language
"vpc_MerchTxnRef"  orderId // Should be Unique for each payment
"vpc_Merchant"  // merchant ID
"vpc_OrderInfo"  // Desc or and details of Product
"vpc_ReturnURL" // SuccessUrl
"vpc_Version" = '1'
&vpc_SecureHash = // create MD5 of all the values that are passed  */

创建Url

    $SECURE_SECRET = "YEOCOEN29B0785F1FF1E3C0FA8A3FUJK";  
        $accessCode = '546484645';

     $amount ='10.00';
    $unique_id = rand(999999,8988888888);//this is a sample random no
        $postdata = array(
                "vpc_AccessCode" => $accessCode,

        $appendAmp = 0;

        foreach ($wpay_postdata as $key => $value) {

                } else {
                    $vpcURL .= '&' . urlencode($key) . "=" . urlencode($value);
                }
                $md5Hash .= $value;
            }
        }
        if (strlen($SECURE_SECRET) > 0) {

        }
        header("Location: " . $vpcURL)

您可以使用Omnipay PHP库，它支持MIGS网关。

一个场外支付处理(三方)的示例如下:

use Omnipay'Omnipay;
$gateway = Omnipay::create('Migs_ThreeParty');
$gateway->setMerchantId('foo');
$gateway->setMerchantAccessCode('foo');
$gateway->setSecureHash('foo');
$response = $gateway->purchase(array('amount' => '10.00', 'currency' => 'AUD'))->send();
if ($response->isRedirect()) {
    // redirect to offsite payment gateway
    $response->redirect();
} else {
    // payment failed: display message to customer
    echo $response->getMessage();
}

我尝试在python django中集成MIGS万事达。我遇到了很多问题。以下是我将MIGS与我的web应用程序集成的经验。我使用VPC集成参考3.1.21.1

1. 在实现Mode1 VPC时:我收到了400个错误请求。这要归功于我案子的安全哈希码。

如果用户发送错误的字段名称或未排序的顺序，则会发生此错误。

2. 一旦我解决了Mode1错误，我使用外部支付选择(EPS)，其中我发送VPC_card和VPC_gateway附加字段与Mode1 VPC参数。我收到了400个坏请求。因此，经过与MIGS支持团队的长时间讨论。我们通过将vpc_card更改为vpc_card和vpc_Gateway来解决这个问题。这是文件错误。

3. 一旦我能够绕过卡片类型页面。我尝试完成模式2 VPC实现。所以，在这种情况下，我添加了vpc_CardNum,vpc_vpc_CardExp,vpc_CardSecurityCode附加字段与上述点请求。我发送GET请求。但没有成功。对于卡片详细信息或模式2，我们必须使用POST请求。

4. 对于mode2 VPC，我们应该使用HTTPS而不是HTTP的POST请求。自签名证书就可以了。所以，我发送HTTPS POST请求与额外的参数，但它仍然没有工作，我得到403禁止错误。因为，ajax调用的Content-type是application/json。所以在使用默认的POST内容类型之后。它工作得很好。

在Migs. config.app中，我添加了与Migs无关的系统变量。所以用户可以忽略它
