Hi everybody,

I am quite new to NuSoap and I have a little problem I can't figure out: each time my webservice sends a soap_fault, my client doesn't understand it and I get an "HTTP Error: no data present after HTTP headers" error.

Here is a simple version of my code with only the part who doesn't work.

Code:

The web service
function getUnmatchedOrdersList($login, $pass) {
//Simply returns a new soap_fault
return new soap_fault('SERVER', '', 'You must be authentificated to use this web-service');
}

And the client who simply call the webservice

Code:

$client = new soapclient($WSLocation);
   $parametres = array('login'=> $_SESSION['userLogin'] ,
         'pass' => $_SESSION['userPasswd'] );
$result = $client->call('getUnmatchedOrdersList', $parametres);
$err = $client->getError();

print_r($client->request);
   print_r($client->response);

if ($client->fault) {
      echo 'SOAP!!!!!!Fault: ';
} else if ($err ) {
//Error
   echo 'Error: ' . $err;
} else {
//ok
   echo("ok");
}

Here is what I got when I execute the client code:

Code:

POST /test/webservices/ptws.php HTTP/1.0
Host: localhost
User-Agent: NuSOAP/0.7.2 (1.94)
Content-Type: text/xml; charset=ISO-8859-1

Error: HTTP Error: no data present after HTTP headers

So it seems that my client take the fault for an error. Sad

As a test, I also tried to change the name of the called function with a false name, and if I do that I effectively receive a fault.

Code:

<?xml version="1.0" encoding="ISO-8859-1"?><SOAP-ENV:Envelope SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"
xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"

xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/">
<SOAP-ENV:Body><SOAP-ENV:Fault><faultcode xsi:type="xsd:string">Client</faultcode><faultactor xsi:type="xsd:string"></faultactor><faultstring xsi:type="xsd:string">Operation 'falseMethod' is not defined in the WSDL for this service</faultstring><detail xsi:type="xsd:string"></detail></SOAP-ENV:Fault></SOAP-ENV:Body></SOAP-ENV:Envelope>SOAP!!!!!!Fault:1<div id="main">

Can someone explain me what I did wrong and why my client doesn't receive the faults generated by the server?
Thanks

Good morning everybody,

I searched deeper and I found something really werd.
But first here is the code is use to make the tests:

Code:

The webservice
<?php
error_reporting(E_ERROR | E_WARNING | E_PARSE);
require('nusoap/lib/nusoap.php');

$server = new soap_server();
$server->register('getUnmatchedOrdersList');

function getUnmatchedOrdersList($login, $pass) {
return new soap_fault('SERVER','','Test fault');
}

/** Use the request to (try to) invoke the service */
$HTTP_RAW_POST_DATA = isset($HTTP_RAW_POST_DATA) ? $HTTP_RAW_POST_DATA : '';
$server->service($HTTP_RAW_POST_DATA);

?>

Code:

The simple client
<?php
require_once('includes/nusoap/lib/nusoap.php');
$client = new soapclient("http://localhost/myproject/webservices/ptws_orders.php");
$parametres = array('login'=> 'Dav', 'pass' => 'pass' );
$result = $client->call('getUnmatchedOrdersList',$parametres);

//Check for error
$err = $client->getError();

echo ($client->request);
echo ($client->response);

if ( $client->fault) {
echo("SOAP fault: ".$client->faultstring);
} else if ($err) {
echo ('Error: ' . $err);
} else {
echo ("OK");
}

?>

Now if I run the previous code on my first development server which is running on Apache 2.0.59 with PHP 5.2.0 I have the following result:
"Error: HTTP Error: no data present after HTTP headers" which is not the excepted one.

BUT, if I run it on my second server which is running on Apache 1.3.33 with PHP 4.3.10 I have the following result:
"SOAP fault: Test fault" which is the good one. Shocked

Has someone ever had this kind of problem? I don't understand where do the problem comes from, can it be the configuration of the server?

Thanks

Hello again,

I put back the error reporting on my web-service and I think I found the reason of the error :

Code:

Catchable fatal error: Object of class soap_fault could not be converted to string in F:\Projet Industriel\site\webservices\nusoap\lib\nusoap.php on line 3613 
SOAP Error: Response not of type text/xml

Can someone tell me if it's a problem of the library or if I did something wrong?
Are there any workarounds?

Any help is welcome.
Thanks

it means that your server did not respond with a soap (xml) as it would expected.
