PHP构建指定SOAP信封SOAPVAR负载遇「无凭据」错误求助

尝试为指定SOAP信封构建PHP对象，因不熟悉PHP语法，在嵌套凭据部分出现问题，端点返回错误提示「No Credentials Found」。

负载示例 #

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:hyp="http://www.globalprocessing.ae/HyperionWeb">   
<soapenv:Header>      
   <hyp:AuthSoapHeader>                  
         <hyp:strUserName></hyp:strUserName>
         <hyp:strPassword></hyp:strPassword>
      </hyp:AuthSoapHeader>
   </soapenv:Header>
   <soapenv:Body>
      <hyp:Ws_AddUpDelCredentials>
         <hyp:WSID></hyp:WSID>

         <hyp:PublicToken></hyp:PublicToken>
         <hyp:Action></hyp:Action>
         <hyp:Credentials>
            <hyp:Credential>
               <hyp:ID></hyp:ID>
               <hyp:Type></hyp:Type>
               <hyp:Value></hyp:Value>
               <hyp:KBA_Answer></hyp:KBA_Answer>
               <hyp:KBA_AnswerOldValue></hyp:KBA_AnswerOldValue>
            </hyp:Credential>         
         </hyp:Credentials> 
      </hyp:Ws_AddUpDelCredentials>   
</soapenv:Body></soapenv:Envelope>

现有类结构 #

class Ws_AddUpDelCredentialsRequest {

  public $paramData;        
  public function __construct($ns, $instCode, $cardToken, $action, $credentials) {
      $this->paramData[] = new SoapVar(date('jnmhis') . rand(1000, 9999), null, null, null, 'WSID', $ns);
      $this->paramData[] = new SoapVar(substr($instCode, 0, 3), null, null, null, 'IssCode', $ns);
      $this->paramData[] = new SoapVar($cardToken, null, null, null, 'PublicToken', $ns);
      $this->paramData[] = new SoapVar($action, null, null, null, 'Action', $ns);
      $this->paramData[] = new SoapVar($credentials, null, null, null, 'Credentials', $ns);
  }
}
        
class Ws_Credential {
        
  public $paramData;            
  public function __construct($ns, $id, $type, $value) {
      $this->paramData[] = new SoapVar($id, null, null, null, 'ID', $ns);
      $this->paramData[] = new SoapVar($type, null, null, null, 'Type', $ns);
      $this->paramData[] = new SoapVar($value, null, null, null, 'Value', $ns);
  }
}

调用代码 #

$addUpDelCredentialsResponse = $soapClient->__soapCall(
                 'Ws_AddUpDelCredentials',
                 $addUpDelCredentialsRequest->paramData,
                 array("soapaction" => 'http://www.globalprocessing.ae/HyperionWeb' . "/Ws_AddUpDelCredentials"));

解决方案 #

1. 完善Ws_Credential类，补充缺失字段 #

原类未包含SOAP负载中的KBA_Answer和KBA_AnswerOldValue字段，需补充：

class Ws_Credential {
    public $paramData;            
    public function __construct($ns, $id, $type, $value, $kbaAnswer = null, $kbaAnswerOldValue = null) {
        $this->paramData[] = new SoapVar($id, null, null, null, 'ID', $ns);
        $this->paramData[] = new SoapVar($type, null, null, null, 'Type', $ns);
        $this->paramData[] = new SoapVar($value, null, null, null, 'Value', $ns);
        if ($kbaAnswer !== null) {
            $this->paramData[] = new SoapVar($kbaAnswer, null, null, null, 'KBA_Answer', $ns);
        }
        if ($kbaAnswerOldValue !== null) {
            $this->paramData[] = new SoapVar($kbaAnswerOldValue, null, null, null, 'KBA_AnswerOldValue', $ns);
        }
    }
}

2. 创建Ws_Credentials类作为容器 #

SOAP结构中Credentials是包含Credential的父节点，需单独创建类做层级包装：

class Ws_Credentials {
    public $paramData;
    public function __construct($ns, $credential) {
        // 将单个Credential对象包装到Credentials节点下
        $this->paramData[] = new SoapVar($credential->paramData, SOAP_ENC_OBJECT, null, null, 'Credential', $ns);
    }
}

3. 调整Ws_AddUpDelCredentialsRequest构造逻辑 #

确保Credentials节点正确嵌套到请求结构中：

class Ws_AddUpDelCredentialsRequest {
    public $paramData;        
    public function __construct($ns, $instCode, $cardToken, $action, $credentials) {
        $this->paramData[] = new SoapVar(date('jnmhis') . rand(1000, 9999), null, null, null, 'WSID', $ns);
        $this->paramData[] = new SoapVar(substr($instCode, 0, 3), null, null, null, 'IssCode', $ns);
        $this->paramData[] = new SoapVar($cardToken, null, null, null, 'PublicToken', $ns);
        $this->paramData[] = new SoapVar($action, null, null, null, 'Action', $ns);
        // 传入包装后的Credentials容器对象
        $this->paramData[] = new SoapVar($credentials->paramData, SOAP_ENC_OBJECT, null, null, 'Credentials', $ns);
    }
}

4. 修正__soapCall调用方式 #

__soapCall的第二个参数需为包含请求对象的数组，而非直接传递paramData：

// 构建单个Credential对象
$credential = new Ws_Credential($ns, $id, $type, $value, $kbaAnswer, $kbaAnswerOldValue);
// 构建Credentials容器
$credentials = new Ws_Credentials($ns, $credential);
// 构建完整请求对象
$addUpDelCredentialsRequest = new Ws_AddUpDelCredentialsRequest($ns, $instCode, $cardToken, $action, $credentials);

// 修正后的SOAP调用
$addUpDelCredentialsResponse = $soapClient->__soapCall(
    'Ws_AddUpDelCredentials',
    array($addUpDelCredentialsRequest->paramData),
    array("soapaction" => 'http://www.globalprocessing.ae/HyperionWeb/Ws_AddUpDelCredentials')
);

5. 补充SOAP Header验证 #

不要遗漏设置SOAP Header中的AuthSoapHeader，否则可能导致请求权限验证失败：

// 创建认证头对象
$authHeader = new SoapVar(
    array(
        'strUserName' => '你的用户名',
        'strPassword' => '你的密码'
    ),
    SOAP_ENC_OBJECT,
    null,
    null,
    'AuthSoapHeader',
    $ns
);
// 为SOAP客户端设置认证头
$soapClient->__setSoapHeaders(array($authHeader));
