Php 将头身份验证信息传递给WSDL

我的SOAP WSDL请求如下所示：

<?xml version="1.0" encoding="UTF-8"?> 
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
<SOAP-ENV:Body><unit>3452</unit>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>

我的SOAP身份验证参数被发送到服务器，但它并没有显示在SOAP请求文本中。我需要看到他们的请求消息

我需要在WSDL文件中添加哪些类型的代码才能获得请求文本，如下所示

<?xml version="1.0" encoding="UTF-8"?> 
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
  <SOAP-ENV:Header>
    <Login>BonZ</Login>
    <Password>xxxx</Password>
  </SOAP-ENV:Header>
  <SOAP-ENV:Body>
    <unit>3452</unit>
  </SOAP-ENV:Body>
</SOAP-ENV:Envelope>

邦兹
xxxx
3452

<?xml version="1.0" encoding="UTF-8"?> 
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
  <SOAP-ENV:Header>
    <Login>BonZ</Login>
    <Password>xxxx</Password>
  </SOAP-ENV:Header>
  <SOAP-ENV:Body>
    <unit>3452</unit>
  </SOAP-ENV:Body>
</SOAP-ENV:Envelope>

$CREDENTIALS = 'Login:Password';
        $auth = base64_encode($CREDENTIALS);
        $context = array('http' =>
            array(
                'header'  => "Authorization: Basic ".$auth
            )
        );

$trac["stream_context"]=stream_context_create($context);
$client = new SoapClient("call.wsdl",array(
"trace"      => 1,
"exceptions" => 0,
"login" => 'xxxxx',
"password" => 'xxxx'
"stream_context"=>stream_context_create($context)
));
