我正在寻找一个 Java HSBC API 支付网关脚本。我用 php 开发了它，但是来到 java 我怎么能这样做。下面是我使用的 php 代码
$ch = curl_init();
$url = ‘https://www.secure-epayments.apixml.hsbc.com’;
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $xml_data_will_go_here);
ob_start();
$data = curl_exec($ch);
curl_close ($ch);
ob_end_clean();
