我正在尝试实施万事达卡支付网关服务，它正在给予HTTP状态400

我没能得到成功的结果

        $amount=10;
        $SECURE_SECRET =  $signature; //value from migs payment gateway
        $accessCode    =  $accesscode;//value from migs payment gateway

        $paymentdata = array(
                 "vpc_AccessCode" => $accessCode,
                 "vpc_Amount" => ($amount*100),//our product price , must multipy by 100
                 "vpc_Command" => 'pay',

        $actionurl ='https://migs.mastercard.com.au/vpcpay?';

        $appendAmp = 0;
        foreach ($paymentdata as $key => $value) {
            // create the md5 input and URL
            if (strlen($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;

                    $actionurl .= '&' . urlencode($key) . "=" . urlencode($value);
                }
                $HashData .= $value;
            }
        }


        if (strlen($SECURE_SECRET) > 0){$actionurl .= "&vpc_SecureHash=" . strtoupper(md5($HashData));}
        header("Location: " . $actionurl);

我在返回URL中尝试了不同的URL，但它给出了HTTP 404状态错误。

快速浏览。。不确定这是否是问题所在。但是您的$amount是一个字符串变量，它不应该是整数吗？没有括号“？您将数组中的字符串乘以100。@baboizk实际上我正在测试，我已经检查了这一点，我也应用了$amount=10，但两者都不是working@nullvoid你把它整理好了吗？
