__doRequest() to change some content before call

[Xavier <xav@spotk.net>]

Hi list,

i've got interop problem with a server, and i've read that i can modify 
soap request content if i subclass soapClient and overload __doRequest 
Method, i tried this, but i can't manage to get it working...

i've added a log method to see if my request is ok before calling the 
parent method, and it is, but any modification done in this step seems 
to be non operant after parent::__doRequest call and therefor in not 
shown in $client->__getLastRequest();

Here is the code i use, if somebody can tell my why, thanks in advance.

Cheers
Xavier

<?php

class MySoapClient extends SoapClient
{
   function __construct($wdsl, $params)
   {
       parent::__construct($wdsl, $params);
   }

   function __doRequest($request, $location, $action, $version) {
   
   $request = str_replace('ns2', 'soapHeader', $request);
   $this->_log($request);
   return parent::__doRequest($request, $location, $action, $version);
   
   }


   function _log($req)
   {
     ob_start();
     print_r($req);
     $out = date('H:i:s') . "  _ _ _ _ _ _ _ _ _ _ _ _ _ _ \n";
     $out .= ob_get_clean() . "\n\n";
   
     $fh = fopen('test.txt', 'a');
     fwrite($fh, $out);
     fclose($fh);
   }
}


$client = new MySoapClient("mywsdl.wsdl",array(
"trace"      => 1,
"exceptions" => 0,
'location'=> 'http://localhost/soapserver/server.php'
));

$ns = 'soapHeader';

$clientName = 'Boobi';
$userName = 'xav';
$password = 'Boo';

$dataAuth = array(
   'ClientName' => new SoapVar($clientName, XSD_STRING, null, null, 
null, $ns),
   'UserName' => new SoapVar($userName, XSD_STRING, null, null, null, 
$ns),
   'Password' => new SoapVar($password, XSD_STRING, null, null, null, 
$ns),
);

$hBody = new SoapVar($dataAuth, SOAP_ENC_OBJECT);
$header= new SoapHeader($ns, 'AuthenticationHeader', $hBody);

$client->__setSoapHeaders(array($header));

 $client->getContractors();

 //$client->getContractors();
 print "<xmp>\n";
 print "Request :\n". $client->__getLastRequest() ."\n";
 print "Response:\n". $client->__getLastResponse()."\n";
 print "</xmp>";
?>
-------------------------------------------

here is the request return by my log method before parent::__doRequest, 
for my needs it's ok

<?xml version="1.0" encoding="UTF-8"?>
<SOAP-ENV:Envelope 
xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"; 
xmlns:ns1="http://www.data.com/inventorymsgs/v1"; 
xmlns:soapHeader="soapHeader"><SOAP-ENV:Header>
<soapHeader:AuthenticationHeader>
<soapHeader:ClientName>Boobi</soapHeader:ClientName>
<soapHeader:UserName>xav</soapHeader:UserName>
<soapHeader:Password>Boo</soapHeader:Password>
</soapHeader:AuthenticationHeader></SOAP-ENV:Header>
<SOAP-ENV:Body><ns1:GetContractorsRequest/></SOAP-ENV:Body></SOAP-ENV:Envelope> 



-----------------------
Here is what __getLastRequest() returns , it's the same request as 
before calling my custom __doRequest

---------------------------

<?xml version="1.0" encoding="UTF-8"?>
<SOAP-ENV:Envelope 
xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"; 
xmlns:ns1="http://www.data.com/inventorymsgs/v1"; xmlns:ns2="soapHeader">
<SOAP-ENV:Header>
<ns2:AuthenticationHeader>
<ns2:ClientName>Boobi</ns2:ClientName>
<ns2:UserName>xav</ns2:UserName>
<ns2:Password>Boo</ns2:Password>
</ns2:AuthenticationHeader>
</SOAP-ENV:Header>
<SOAP-ENV:Body><ns1:GetContractorsRequest/></SOAP-ENV:Body></SOAP-ENV:Envelope>
