PHP+BillDesk 支付网关集成问题

Question

我正在尝试将 BillDesk 支付网关与我的 PHP 网站集成。 运行简单的 PHP 代码时出现以下错误

{"status":422,"error_type":"invalid_data_error","error_code":"GNIDE0004","message":"Invalid Content-type header"}

这是我的 PHP 代码。 请注意，这仅用于测试目的

<?php
$str = "<MerchantId>|order45608988|NA|300.00|NA|NA|NA|INR|NA|TypeField1|<ClientID>|NA|NA|TypeField2|Txtadditionalinfo1|Txtadditionalinfo2|http://google.com";

$checksum = hash_hmac('sha256',$str,"<secretkey>", false); 
$checksum_value = strtoupper($checksum);


echo '<form action="https://pguat.billdesk.io/payments/ve1_2/orders/create" method="post" id="billdesk_payment_form">';
echo '<input type="hidden" name="MerchantId" value="<MerchantId>"/>';
echo '<input type="hidden" name="CurrencyType" value="INR"/>';
echo '<input type="hidden" name="SecurityId" value="<ClientID>"/>';
echo '<input type="hidden" name="txtCustomerID" value="order45608988" />';
echo '<input type="hidden" name="txtTxnAmount" value="300.00" />';
echo '<input type="hidden" name="txtAdditionalInfo1″ value="" />';
echo '<input type="hidden" name="RU" value="http://returnURL.com" />';
echo '<input type="hidden" name="CheckSumKey" value="<secretkey>"/>';
echo '<input type="hidden" name="CheckSum" value="'.$checksum_value.'"/>';
echo '<input type="hidden" name="msg" value="'.$str.'" />';
echo '</form>';

echo '<script>document.getElementById("billdesk_payment_form").submit();</script>';
?>

我已经参考了 BillDesk 文档，但我并没有得到我必须做的确切更改。

先感谢您。

不适合我。 您使用了很多参数，但没有在任何地方定义。 你能在这里分享完整的代码吗
