我正在尝试连接到受密码保护且 URL 为 https 的 Web 服务。在脚本发出请求之前，我无法弄清楚如何进行身份验证。一旦我定义了服务，它似乎就会发出请求。例如，如果我输入：

$client = new SoapClient("https://example.com/WSDL/nameofservice",
       array('trace' => 1,)
);

然后在浏览器上访问该站点，我得到：

Fatal error: Uncaught SoapFault exception: 
[WSDL] SOAP-ERROR: Parsing WSDL: Couldn't load from
'https://example.com/WSDL/nameofservice' in /path/to/my/script/myscript.php:2 
Stack trace: #0 /path/to/my/script/myscript.php(2): 
SoapClient->SoapClient('https://example...', Array) #1 {main} thrown in 
/path/to/my/script/myscript.php on line 2

如果我尝试将服务定义为 Soap 服务器，例如：

$server= new SoapServer("https://example.com/WSDL/nameofservice");

我得到：

<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
<SOAP-ENV:Body>
<SOAP-ENV:Fault>
<faultcode>WSDL</faultcode>
<faultstring>
SOAP-ERROR: Parsing WSDL: 
Couldn't load from 'https://example.com/WSDL/nameofservice'
</faultstring>
</SOAP-ENV:Fault>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>

我还没有尝试发送原始请求信封以查看服务器返回的内容，但这可能是一种解决方法。但我希望有人能告诉我如何使用 php 内置类来设置它。我尝试将“userName”和“password”添加到数组中，但这并不好。问题是我什至无法判断我是否到达了远程站点，更不用说它是否拒绝了请求。

只需扩展 SoapHeader 以创建 Wsse 兼容认证：

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);
}
}



$wsse_header = new WsseAuthHeader($username, $password);
$x = new SoapClient('{...}', array("trace" => 1, "exception" => 0));
$x->__setSoapHeaders(array($wsse_header));

如果您需要使用带有 nonce 和时间戳的 ws-security，Peter 在http://php.net/manual/en/soapclient.soapclient.php#114976上发布了一个更新版本，他写道它确实适用于他：

class WsseAuthHeader extends SoapHeader
{
    private $wss_ns = 'http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd';
    private $wsu_ns = 'http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd';

    function __construct($user, $pass)
    {
        $created    = gmdate('Y-m-d\TH:i:s\Z');
        $nonce      = mt_rand();
        $passdigest = base64_encode(pack('H*', sha1(pack('H*', $nonce) . pack('a*', $created) . pack('a*', $pass))));

        $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);
        $auth->Nonce    = new SoapVar($passdigest, XSD_STRING, NULL, $this->wss_ns, NULL, $this->wss_ns);
        $auth->Created  = new SoapVar($created, XSD_STRING, NULL, $this->wss_ns, NULL, $this->wsu_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);
    }
}

问题似乎是 WSDL 文档以某种方式受到保护（基本身份验证 - 我不认为摘要式身份验证受支持SoapClient，所以在这种情况下你会不走运），SoapClient因此无法读取和解析服务描述。

首先，您应该尝试在浏览器中打开 WSDL 位置，以检查是否显示了身份验证对话框。如果有一个身份验证对话框，您必须确保SoapClient在检索 WSDL 文档时使用了所需的登录凭据。问题是它SoapClient只会在调用服务时创建客户端时发送使用loginandpassword选项（以及使用证书身份验证时的选项）给出的凭据，而不是在获取 WSDL 时发送（参见此处）。有两种方法可以解决这个问题：local_cert

  1. SoapClient在构造函数调用中将登录凭据添加到 WSDL url

    $client = new SoapClient(
    'https://' . urlencode($login) . ':' . urlencode($password) . '@example.com/WSDL/nameofservice',
    array(
        'login' => $login,
        'password' => $password
    )
);

    这应该是最简单的解决方案 - 但在 PHP Bug #27777中写到这也不起作用（我还没有尝试过）。

  2. 使用 HTTP 流包装器手动获取 WSDL，ext/curl或者通过浏览器手动获取 WSDL wget，例如，将其存储在磁盘上并SoapClient使用对本地 WSDL 的引用进行实例化。

    如果 WSDL 文档发生更改，此解决方案可能会出现问题，因为您必须检测更改并将新版本存储在磁盘上。

如果未显示身份验证对话框并且您可以在浏览器中阅读 WSDL，则应提供更多详细信息以检查其他可能的错误/问题。

这个问题绝对与服务本身无关，因为SoapClient在发出对服务本身的调用之前已经在读取服务描述文档时阻塞了。

编辑：

将 WSDL 文件保存在本地是第一步——这将允许SoapClient用户知道如何与服务进行通信。WSDL 是直接从服务位置提供服务、从另一台服务器提供服务还是从本地文件读取都没有关系 - 服务 url 在 WSDL 中编码，因此SoapClient始终知道在哪里查找服务端点。

现在的第二个问题是它SoapClient本身不支持WS-Security规范，这意味着您必须扩展SoapClient以处理特定的标头。添加所需行为的扩展点是在将SoapClient::__doRequest()XML 有效负载发送到服务端点之前对其进行预处理。但我认为自己实施 WS-Security 解决方案需要对特定的 WS-Security 规范有相当的了解。也许 WS-Security 标头也可以通过使用SoapClient::__setSoapHeaders()和适当SoapHeader的 s 创建并打包到 XML 请求中，但我怀疑这是否可行，将自定义SoapClient扩展作为唯一的可能性。

一个简单的SoapClient扩展将是

class My_SoapClient extends SoapClient
{
    protected function __doRequest($request, $location, $action, $version) 
    {
        /*
         * $request is a XML string representation of the SOAP request
         * that can e.g. be loaded into a DomDocument to make it modifiable.
         */
        $domRequest = new DOMDocument();
        $domRequest->loadXML($request);

        // modify XML using the DOM API, e.g. get the <s:Header>-tag 
        // and add your custom headers
        $xp = new DOMXPath($domRequest);
        $xp->registerNamespace('s', 'http://www.w3.org/2003/05/soap-envelope');
        // fails if no <s:Header> is found - error checking needed
        $header = $xp->query('/s:Envelope/s:Header')->item(0);

        // now add your custom header
        $usernameToken = $domRequest->createElementNS('http://schemas.xmlsoap.org/ws/2002/07/secext', 'wsse:UsernameToken');
        $username = $domRequest->createElementNS('http://schemas.xmlsoap.org/ws/2002/07/secext', 'wsse:Username', 'userid');
        $password = $domRequest->createElementNS('http://schemas.xmlsoap.org/ws/2002/07/secext', 'wsse:Password', 'password');
        $usernameToken->appendChild($username);
        $usernameToken->appendChild($password);
        $header->appendChild($usernameToken);

        $request = $domRequest->saveXML();
        return parent::__doRequest($request, $location, $action, $version);
    }
}

对于基本的 WS-Security 身份验证，您必须将以下内容添加到 SOAP-header：

<wsse:UsernameToken>
    <wsse:Username>userid</wsse:Username>
    <wsse:Password>password</wsse:Password>                                 
</wsse:UsernameToken>

但正如我上面所说：我认为需要更多关于 WS-Security 规范和给定服务架构的知识才能使其正常工作。

如果您需要整个 WS-* 规范范围的企业级解决方案，并且如果您可以安装 PHP 模块，您应该查看WSO2 Web Services Framework for PHP (WSO2 WSF/PHP)

对于密码摘要安全性，您可以使用以下内容：

   /**
    * This function implements a WS-Security digest authentification for PHP.
    *
    * @access private
    * @param string $user
    * @param string $password
    * @return SoapHeader
    */
   function soapClientWSSecurityHeader($user, $password)
   {
      // Creating date using yyyy-mm-ddThh:mm:ssZ format
      $tm_created = gmdate('Y-m-d\TH:i:s\Z');
      $tm_expires = gmdate('Y-m-d\TH:i:s\Z', gmdate('U') + 180); //only necessary if using the timestamp element

      // Generating and encoding a random number
      $simple_nonce = mt_rand();
      $encoded_nonce = base64_encode($simple_nonce);

      // Compiling WSS string
      $passdigest = base64_encode(sha1($simple_nonce . $tm_created . $password, true));

      // Initializing namespaces
      $ns_wsse = 'http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd';
      $ns_wsu = 'http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd';
      $password_type = 'http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-profile-1.0#PasswordDigest';
      $encoding_type = 'http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-soap-message-security-1.0#Base64Binary';

      // Creating WSS identification header using SimpleXML
      $root = new SimpleXMLElement('<root/>');

      $security = $root->addChild('wsse:Security', null, $ns_wsse);

      //the timestamp element is not required by all servers
      $timestamp = $security->addChild('wsu:Timestamp', null, $ns_wsu);
      $timestamp->addAttribute('wsu:Id', 'Timestamp-28');
      $timestamp->addChild('wsu:Created', $tm_created, $ns_wsu);
      $timestamp->addChild('wsu:Expires', $tm_expires, $ns_wsu);

      $usernameToken = $security->addChild('wsse:UsernameToken', null, $ns_wsse);
      $usernameToken->addChild('wsse:Username', $user, $ns_wsse);
      $usernameToken->addChild('wsse:Password', $passdigest, $ns_wsse)->addAttribute('Type', $password_type);
      $usernameToken->addChild('wsse:Nonce', $encoded_nonce, $ns_wsse)->addAttribute('EncodingType', $encoding_type);
      $usernameToken->addChild('wsu:Created', $tm_created, $ns_wsu);

      // Recovering XML value from that object
      $root->registerXPathNamespace('wsse', $ns_wsse);
      $full = $root->xpath('/root/wsse:Security');
      $auth = $full[0]->asXML();

      return new SoapHeader($ns_wsse, 'Security', new SoapVar($auth, XSD_ANYXML), true);
   }

要将它与 PHP SoapClient 一起使用，请使用以下方式：

$client = new SoapClient('http://endpoint');
$client->__setSoapHeaders(soapClientWSSecurityHeader('myUser', 'myPassword'));
// $client->myService(array('param' => 'value', ...);

我有比扩展现有的soapclient 库更简单的解决方案。

Step1：创建两个类来为WSSE headers创建一个结构

class clsWSSEAuth {
    private $Username;
    private $Password;
    function __construct($username, $password) {
        $this->Username=$username;
        $this->Password=$password;
    }
}

class clsWSSEToken {
    private $UsernameToken;
    function __construct ($innerVal){
        $this->UsernameToken = $innerVal;
    }
}

Step2：为用户名和密码创建肥皂变量

$username = 1111;
$password = 1111;

//Check with your provider which security name-space they are using.
$strWSSENS = "http://schemas.xmlsoap.org/ws/2002/07/secext";

$objSoapVarUser = new SoapVar($username, XSD_STRING, NULL, $strWSSENS, NULL, $strWSSENS);
$objSoapVarPass = new SoapVar($password, XSD_STRING, NULL, $strWSSENS, NULL, $strWSSENS);

Step3：为Auth Class创建对象并传入soap var

$objWSSEAuth = new clsWSSEAuth($objSoapVarUser, $objSoapVarPass);

Step4：从 Auth 类的对象中创建 SoapVar

$objSoapVarWSSEAuth = new SoapVar($objWSSEAuth, SOAP_ENC_OBJECT, NULL, $strWSSENS, 'UsernameToken', $strWSSENS);

Step5：为Token Class创建对象

$objWSSEToken = new clsWSSEToken($objSoapVarWSSEAuth);

Step6：从 Token 类的对象中创建 SoapVar

$objSoapVarWSSEToken = new SoapVar($objWSSEToken, SOAP_ENC_OBJECT, NULL, $strWSSENS, 'UsernameToken', $strWSSENS);

第 7 步：为“安全”节点创建 SoapVar

$objSoapVarHeaderVal=new SoapVar($objSoapVarWSSEToken, SOAP_ENC_OBJECT, NULL, $strWSSENS, 'Security', $strWSSENS);

Step8：从安全soapvar中创建头对象

$objSoapVarWSSEHeader = new SoapHeader($strWSSENS, 'Security', $objSoapVarHeaderVal,true, 'http://abce.com');

//Third parameter here makes 'mustUnderstand=1
//Forth parameter generates 'actor="http://abce.com"'

Step9：创建Soap Client对象

$objClient = new SoapClient($WSDL, $arrOptions);

Step10：设置soapclient对象的headers

$objClient->__setSoapHeaders(array($objSoapVarWSSEHeader));

第 11 步：最终调用方法

$objResponse = $objClient->__soapCall($strMethod, $requestPayloadString);

   {
      // Creating date using yyyy-mm-ddThh:mm:ssZ format

      $tm_expires = gmdate('Y-m-d\TH:i:s\Z', gmdate('U') + 180); //only necessary if using the timestamp element

      // Generating and encoding a random number
      $simple_nonce = mt_rand();
      $encoded_nonce = base64_encode($simple_nonce);

      // Compiling WSS string
      $passdigest = base64_encode(sha1($simple_nonce . $tm_created . $password, true));

      // Initializing namespaces

      $encoding_type = 'http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-soap-message-security-1.0#Base64Binary';

      // Creating WSS identification header using SimpleXML
      $root = new SimpleXMLElement('<root/>');

      $security = $root->addChild('wsse:Security', null, $ns_wsse);

      //the timestamp element is not required by all servers
      $timestamp = $security->addChild('wsu:Timestamp', null, $ns_wsu);
      $timestamp->addAttribute('wsu:Id', 'Timestamp-28');
      $timestamp->addChild('wsu:Created', $tm_created, $ns_wsu);
      $timestamp->addChild('wsu:Expires', $tm_expires, $ns_wsu);

      $usernameToken = $security->addChild('wsse:UsernameToken', null, $ns_wsse);
      $usernameToken->addChild('wsse:Username', $user, $ns_wsse);
      $usernameToken->addChild('wsse:Password', $password, $ns_wsse)->addAttribute('Type', $password_type);
      $usernameToken->addChild('wsse:Nonce', $encoded_nonce, $ns_wsse)->addAttribute('EncodingType', $encoding_type);
      $usernameToken->addChild('wsu:Created', $tm_created, $ns_wsu);

      // Recovering XML value from that object
      $root->registerXPathNamespace('wsse', $ns_wsse);
      $full = $root->xpath('/root/wsse:Security');
      $auth = $full[0]->asXML();

      return new SoapHeader($ns_wsse, 'Security', new SoapVar($auth, XSD_ANYXML), true);
   }

要调用它，请使用

$client = new SoapClient('YOUR ENDPOINT');
$userid = "userid";
$password = "password"; 
$client->__setSoapHeaders(soapClientWSSecurityHeader($userid,$password));
