如何使用在PHP页面上使用自定义用户名验证的WCF Web服务？

Question

我很难从PHP站点使用安全的WCF Web服务.我在PHP方面的知识是有限的,我在网上找到了各种各样的例子但是没有成功使它们工作.

我有一个Silverlight应用程序也使用此WebService,它工作正常.但是当我运行PHP站点时,我收到此错误:

MessageSecurityException:安全性处理器无法在消息中找到安全标头.这可能是因为消息是不安全的故障,或者因为通信方之间存在绑定不匹配.如果为安全性配置服务且客户端未使用安全性,则会发生这种情况.

我还尝试将customBinding更改为basicHttpBinding.当我这样做时,不再调用自定义用户名验证器.但是,使用basicHttpBinding并删除我的WCF服务上的凭据验证"工作"(除了它是不安全的事实).所以这个问题似乎与安全信息有关.

有人可以给我一个工作示例或教程,可以帮助我使这个PHP页面工作吗？

这是我的PHP代码:

    $options = array( 
            'soap_version'  => SOAP_1_1, 
            'exceptions'    => true, 
            'trace'         => 1, 
            'cache_wsdl'    => WSDL_CACHE_NONE,
            'Username'      => 'MyUserName', 
            'password'      => 'MyPassword');

$client = new SoapClient('https://UrlToService/Service.svc?wsdl', $options); 

try
{
    $phpresponse = $client->Get(); 

    print $phpresponse->GetResult->Version;
    echo "</b><BR/><BR/>";
}
catch(Exception $e) 
{ 
    echo "<h2>Exception Error!</h2></b>"; 
    echo $e->getMessage(); 
    echo "<BR/><BR/>";
}

WCF配置

<behavior name="sslBehavior">
   <serviceMetadata httpsGetEnabled="true" />
   <serviceDebug includeExceptionDetailInFaults="true" />
   <serviceCredentials>
      <userNameAuthentication userNamePasswordValidationMode="Custom"   customUserNamePasswordValidatorType="MyNamespace.ServiceUserNameValidator, MyNamespace" />
   </serviceCredentials>
   <serviceSecurityAudit
    auditLogLocation="Application"
    serviceAuthorizationAuditLevel="Failure"
    messageAuthenticationAuditLevel="Failure"
    suppressAuditFailure="true" />
</behavior>

<customBinding>
    <binding name="sslCustomBinding">
      <security authenticationMode="UserNameOverTransport" includeTimestamp="true" allowInsecureTransport="true">
        <localServiceSettings maxClockSkew="00:10:00" />
        <localClientSettings maxClockSkew="00:10:00" />
        <secureConversationBootstrap />
      </security>
      <textMessageEncoding messageVersion="Soap11" />
      <httpsTransport />
    </binding>
  </customBinding>

<service behaviorConfiguration="sslBehavior" name="MyNamespace.Services.Service">
    <endpoint address="" binding="customBinding" 
              bindingConfiguration="sslCustomBinding" contract="MyNamespace.ServiceContracts.IService" />
    <host>
      <baseAddresses>
        <add baseAddress="https://UrlToService/Services/" />
      </baseAddresses>
    </host>
  </service>

我解决了这个问题.我不得不在PHP中扩展"SoapHeader"类,使其符合WS-Security标准.

这是解决方案:

PHP Header类

class WsseAuthHeader extends SoapHeader 
{
    private $wss_ns = 'http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd';
    function __construct($user, $pass, $ns = null) 
    {    
        if ($ns) 
        {        
            $this->wss_ns = $ns;    
        }    

        $auth = new stdClass();    

        $auth->Username = new SoapVar($user, XSD_STRING, NULL, $this->wss_ns, NULL, $this->wss_ns);     
        $auth->Password = new SoapVar($pass, XSD_STRING, NULL, $this->wss_ns, NULL, $this->wss_ns);    
        $username_token = new stdClass();    
        $username_token->UsernameToken = new SoapVar($auth, SOAP_ENC_OBJECT, NULL, $this->wss_ns, 'UsernameToken', $this->wss_ns);     
        $security_sv = new SoapVar(        
                                new SoapVar($username_token, SOAP_ENC_OBJECT, NULL, $this->wss_ns, 'UsernameToken', $this->wss_ns),        
                                SOAP_ENC_OBJECT, NULL, $this->wss_ns, 'Security', $this->wss_ns);    

        parent::__construct($this->wss_ns, 'Security', $security_sv, true);
    }
}

PHP客户端调用

$options = array( 
            'soap_version'    => SOAP_1_1, 
            'exceptions'      => true, 
            'trace'           => 1, 
            'wdsl_local_copy' => true
            );


$username = "MyUser";
$password = "MyPassword";

$wsse_header = new WsseAuthHeader($username, $password);    

$client = new SoapClient('https://UrlToService/Service.svc?wsdl', $options); 
$client->__setSoapHeaders(array($wsse_header));

try
{
    $phpresponse = $client->Get(); 

    print $phpresponse->GetResult->Version;
    echo "</b><BR/><BR/>";
}
catch(Exception $e) 
{ 
    echo "<h2>Exception Error!</h2></b>"; 
    echo $e->getMessage(); 
}

希望它会帮助别人!
