SOAP PHP请求错误 - SOAP PHP request error

我使用第三方api请求余额。我在不同的尝试中犯了很多错误，但我知道我已经接近了。这是我的电话号码。。。

<?php 
try {   
$wsdl_url = 'https://www.domain.com/SOAP?wsdl';
$UserID = 'UserID';
$Pwd= 'Password';
$client = new SOAPClient($wsdl_url);
$headerbody = array( 
                     'UsernameToken'=>array('Username'=>$UserID, 
                                             'Password'=>$Pwd)); 
//Create Soap Header.        
$header = new SOAPHeader('wsse', 'Security', $headerbody);        
//set the Headers of Soap Client. 
$client->__setSoapHeaders($header); 
//$client->__getLastResponse();
$BalanceInquiryRequest->AccountNo="7777700020";
$BalanceInquiryRequest->RetailerId="0123";
$getBalance = $client->balanceInquiry($BalanceInquiryRequest);
print_r($getBalance); 
} catch (SoapFault $fault) {
echo $fault->faultcode . "-" . $fault->faultstring;  
//echo "REQUEST:'n" . htmlentities($client->__getLastRequest()) . "'n";
}
?>

这个的输出是…

env:Server-java.lang.NullPointerException

这是请求的xml。。。

<soapenv:Envelope xmlns:req="http://domain.com" xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
   <soapenv:Header>
      <wsse:Security soapenv:mustUnderstand="0" xmlns:wsse="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd" xmlns:wsu="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd">

      </wsse:Security>

   <soapenv:Body>

         <req:AccountNo>7777700020</req:AccountNo>
         <req:RetailerId>0123</req:RetailerId>
      </req:BalanceInquiryRequest>
   </soapenv:Body>
</soapenv:Envelope>

好吧，伙计们，问题是我的代码中的WSSE是一个标准，与PHP SOAPClient不太好用。我做了一些研究，发现有几种方法可以让这两者很好地结合在一起。我所做的是首先确定名称空间、用户名和密码。。。

$username = 'USERNAME';
$password = 'PASSWORD';
$strWSSENS = "http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd";

接下来是创建两个类来处理这些信息（在线帮助）。。。

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;
    }
}

然后调用这几个函数来设置标题等…

  $objWSSEAuth = new clsWSSEAuth($objSoapVarUser, $objSoapVarPass);
  $objSoapVarWSSEAuth = new SoapVar($objWSSEAuth, SOAP_ENC_OBJECT, NULL, $strWSSENS, 'UsernameToken', $strWSSENS);
  $objWSSEToken = new clsWSSEToken($objSoapVarWSSEAuth);
  $objSoapVarWSSEToken = new SoapVar($objWSSEToken, SOAP_ENC_OBJECT, NULL, $strWSSENS, 'UsernameToken', $strWSSENS);
  $objSoapVarHeaderVal=new SoapVar($objSoapVarWSSEToken, SOAP_ENC_OBJECT, NULL, $strWSSENS, 'Security', $strWSSENS);
  $objSoapVarWSSEHeader = new SoapHeader($strWSSENS, 'Security', $objSoapVarHeaderVal,true, 'http://abce.com');

然后剩下的一切照常。。。使用SOAPClient。。。
