未获取所需的 SOAP 请求 XML

我正在开发一个使用OCPP(开放充电点协议(的简单php客户端。我已经创建了客户端，这是来自我的代码的请求 XML。

<?xml version="1.0" encoding="UTF-8"?>
  <env:Envelope xmlns:env="http://www.w3.org/2003/05/soap-envelope" xmlns:ns1="urn://Ocpp/Cs/2015/10/">
      <env:Header>
          <ns1:chargeBoxIdentity env:mustUnderstand="true">XXX01</ns1:chargeBoxIdentity>
          <ns1:Action env:mustUnderstand="true">/Authorize</ns1:Action>
          <ns1:MessageId env:mustUnderstand="true">123</ns1:MessageId>
          <ns1:RelatesTo>relatesTo</ns1:RelatesTo>
          <ns1:From/>
          <ns1:ReplyTo/>
          <ns1:To/>
      </env:Header>
      <env:Body>
          <ns1:authorizeRequest>
          <ns1:idTag>1234567</ns1:idTag>
          </ns1:authorizeRequest>
      </env:Body>
  </env:Envelope>

但是我应该得到这个XML输出

<?xml version='1.0' encoding='utf8'?> 
<ns0:Envelope xmlns:ns0="http://www.w3.org/2003/05/soap-envelope" xmlns:ns1="urn://Ocpp/Cs/2015/10/">
    <ns0:Header>
        <ns1:chargeBoxIdentity mustUnderstand="true">XXX01 </ns1:chargeBoxIdentity>
        <ns1:Action mustUnderstand="true">/Authorize</ns1:Action>
        <ns1:MessageId mustUnderstand="true">123</ns1:MessageId>
        <ns1:RelatesTo>relatesTo</ns1:RelatesTo>
        <ns1:From />
        <ns1:ReplyTo />
        <ns1:To />
    </ns0:Header>
    <ns0:Body>
        <ns1:IdTag>1234567</ns1:IdTag>
    </ns0:Body>
</ns0:Envelope>

请注意，我的代码具有env:Envelope，输出具有ns0:Envelope，在我的代码中，额外的属性位于 Soap 正文中。我对php SOAP的了解非常有限。相关代码如下。

ini_set('soap.wsdl_cache_enabled',0);
$wsdl_centralsystem = "OCPP_centralsystemservice_1.5_final.wsdl";
$params =  "0.1.1.255.0.0.1.0.";
$vLocation = "linktoserver/server.php";
$client = new SoapClient($wsdl_centralsystem, array(
    "soap_version" => SOAP_1_2,
    "location" => $vLocation,
    "trace"=>1, "exceptions"=>0,
));
$chargeboxid = "XXX01";
$action = "/Authorize";
$msgid = "123";
$relatesto = "relatesTo";

//Create Soap Headers
$headerCchargeBoxIdentity = new SoapHeader("urn://Ocpp/Cs/2015/10/", 'chargeBoxIdentity', $chargeboxid, true);
$headerAction = new SoapHeader("urn://Ocpp/Cs/2015/10/", 'Action', $action, true);
$headerMessageId = new SoapHeader("urn://Ocpp/Cs/2015/10/", 'MessageId', $msgid, true);
$headerRelatesTo = new SoapHeader("urn://Ocpp/Cs/2015/10/", 'RelatesTo', $relatesto, false);
$headerFrom = new SoapHeader("urn://Ocpp/Cs/2015/10/", 'From', NULL, false);
$headerReplyTo= new SoapHeader("urn://Ocpp/Cs/2015/10/", 'ReplyTo', NULL, false);
$headerTo = new SoapHeader("urn://Ocpp/Cs/2015/10/", 'To', NULL, false);
//set the Headers of Soap Client.
$client->__setSoapHeaders(array($headerCchargeBoxIdentity,$headerAction,$headerMessageId,$headerRelatesTo,$headerFrom,$headerReplyTo,$headerTo));

$output = $client-> __soapCall('Authorize',array($params));
