Question

我正在尝试使用PHP5中的Soap调用Web服务，为此，我需要使用WS-Security 1.1。

（在java和.NET中，这都是自动生成的。）

是否有可用于在PHP中轻松生成安全标头的框架？或者我是否必须自己添加整个标题？

WS-Security 1.1的规格：http://oasis-open.org/committees/download.php/16790/wss-1.1-spec-os-SOAPMessageSecurity.pdf

在PHP Classes，Roger Veciana i Rovira提交了这个（我刚刚重新格式化了代码）：

class WSSoapClient extends SoapClient {

    private $username;
    private $password;
    /*Generates de WSSecurity header*/
    private function wssecurity_header() {

        /* The timestamp. The computer must be on time or the server you are
         * connecting may reject the password digest for security.
         */
        $timestamp = gmdate('Y-m-d\TH:i:s\Z');
        /* A random word. The use of rand() may repeat the word if the server is
         * very loaded.
         */
        $nonce = mt_rand();
        /* This is the right way to create the password digest. Using the
         * password directly may work also, but it's not secure to transmit it
         * without encryption. And anyway, at least with axis+wss4j, the nonce
         * and timestamp are mandatory anyway.
         */
        $passdigest = base64_encode(
                pack('H*',
                        sha1(
                                pack('H*', $nonce) . pack('a*',$timestamp).
                                pack('a*',$this->password))));

        $auth = '
<wsse:Security SOAP-ENV:mustUnderstand="1" xmlns:wsse="http://docs.oasis-open.'.
'org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd">
<wsse:UsernameToken>

   </wsse:UsernameToken>
</wsse:Security>
';

        /* XSD_ANYXML (or 147) is the code to add xml directly into a SoapVar.
         * Using other codes such as SOAP_ENC, it's really difficult to set the
         * correct namespace for the variables, so the axis server rejects the
         * xml.
         */
        $authvalues = new SoapVar($auth,XSD_ANYXML);
        $header = new SoapHeader("http://docs.oasis-open.org/wss/2004/01/oasis-".
            "200401-wss-wssecurity-secext-1.0.xsd", "Security", $authvalues,
                true);

        return $header;
    }

    /* It's necessary to call it if you want to set a different user and
     * password
     */
    public function __setUsernameToken($username, $password) {
        $this->username = $username;
        $this->password = $password;
    }


    /* Overwrites the original method adding the security header. As you can
     * see, if you want to add more headers, the method needs to be modifyed
     */
    public function __soapCall($function_name, $arguments, $options=null,
            $input_headers=null, $output_headers=null) {

        $result = parent::__soapCall($function_name, $arguments, $options,
                $this->wssecurity_header());

        return $result;
    }
}
