尝试在 PHP 中使用 x.509 证书对 SOAP 调用进行数字签名

我正在与一个客户端合作，尝试使用PHP发送和接收肥皂调用。它们设置了 ws-security，并使用 x.509 证书进行身份验证。我已经能够使用SoapUI让它工作，但是我无法在PHP中使用它。

我遇到的问题是，他们不使用标准的二进制安全令牌或用户名/密码组合。他们改为对安全令牌参考中的 XML 文件进行签名。

我一直在尝试使用Rob Richards的库来生成哈希，它似乎包含了代码来做我想做的事情，但我在实现它时一直没有成功。（https://github.com/robrichards/wse-php)

以下是我们应该得到的：

PHP类使这一切工作：

<?php
class MySoap extends SoapClient {
    public function __doRequest($request, $location, $saction, $version) {
        $doc = new DOMDocument('1.0');
        $doc->loadXML($request);

        $objWSSE = new WSSESoap($doc);

        /* add Timestamp with no expiration timestamp */
        $objWSSE->addTimestamp();

        /* create new XMLSec Key using AES256_CBC and type is private key */
        $objKey = new XMLSecurityKey(XMLSecurityKey::RSA_SHA1, array('type' => 'public'));

        /* load the private key from file - last arg is bool if key in file (true) or is string (false) */
        $objKey->loadKey("c:\\xampp\htdocs\\XMLSoapApp\\cert1.pem", $isFile=true, true);

        /* Sign the message - also signs appropiate WS-Security items */
        $options = array("insertBefore" => true);

        $objWSSE->signSoapDoc($objKey, $options);

        /* Add certificate (BinarySecurityToken) to the message */ 
        $token = $objWSSE->addBinaryToken(file_get_contents(combine_key));

        /* Attach pointer to Signature */
        $objWSSE->attachTokentoSig($token);
        return $doc->saveXML();
    }
}

必须有一种方法可以毫不费力地做到这一点，但我似乎错过了它。以前有人这样做过吗？
