PHP IDE :: NuSphere Forums :: View topic - Soap Server with .net type Soap Header Authentication

Posted: Sat Apr 05, 2008 4:00 pm

Hi,

I was wondering if anyone knows how to include .net type soap headers (typically used for authentication) on the SERVER side of nusoap.

So assuming the following sample server code from an IBM redbook...

Code:

<?
require_once("./lib/nusoaplib/nusoap.php");
$ns="http://myurl";

$server = new soap_server();
$server->configureWSDL('ITSOcalcTax',$ns);
$server->wsdl->schemaTargetNamespace=$ns;

$server->register('taxcalc',
array ('amount' => 'xsd:string'),
array ('return' => 'xsd:string'),
$ns);

function taxcalc($amount) {
$calc=$amount * .08;
return new soapval('return','string',$calc);
}

$server->service($HTTP_RAW_POST_DATA);
?>

how do I include soap headers such as...

Code:

$header = (
"<UserCredentials xmlns='http://myurl/'>".
"<userId>".htmlspecialchars($user)."</userId>".
"<password>".htmlspecialchars($pass)."</password>".
"</UserCredentials>"
);

so that I can call the service with the following code...

Code:

<?
require_once("./lib/nusoaplib/nusoap.php");
$wsdl="http://myurl?wsdl";
$client=new soapclient($wsdl,'wsdl');
$user='Guest';
$pass='Test1234';
$param=array('amount'=>1000);

$header = (
"<UserCredentials xmlns='http://myurl/'>".
"<userId>".htmlspecialchars($user)."</userId>".
"<password>".htmlspecialchars($pass)."</password>".
"</UserCredentials>"
);
$results=$client->call('ITsocalcTax',$param,false,false,$header);
print_r($results);
?>

The "UserCredentials" class is pre-defined in the .net world and I need to conform to this.

Thank you.

Hi,

I am posting the reply below that I got from Scott Nichol at sourceforge for the benefit of others asking the same question. I hope that's ok.

Please add more to this thread if you have any input.

Thank you.

There are a couple of instance variables in the nusoap_server class that allow you to access SOAP Headers. Most generally, requestSOAP gives you the full SOAP request (the HTTP payload) as a string. You can then parse anything out of it that you want. The requestHeaders variable gives you just the SOAP headers in string form, with a caveat: namespace resolution is spotty or nonexistent. Finally, requestHeader gives you the headers parsed into associative arrays, similar to what you get as a return value from the call method of nusoap_client.

Your code might look like this (with no error checking):

Hi Scott,

I am not sure yet what the issues will be about the namespace, but I will try what you suggested.

Thank you for answering me.

Hi, thanks for details.

I tried to transfer SOAP header from .NET client to PHP web service as this method was described in this post. But instead login and password values on server side I have that $server->requestHeader is invalid expression in watch window. Sad

Why? Thanks for any help!
PHP version is 5.2.5, Apache version is 2.2.

PHP web service is the same.
.NET client:

Code:

try
{
ITSOcalcTax service = new ITSOcalcTax();
service.Credentials = new NetworkCredential("a", "b");
service.Url = "http://localhost/PhpWebServices/myservice.php?XDEBUG_SESSION_START=3";

string tax = service.taxcalc("100");

Console.WriteLine("tax is " + tax);
}
catch (Exception exception)
{
Console.WriteLine("exception is " + exception.ToString());
}
Console.Read();

Hi everybody

I have found a way to do a personal authentication on a web service. In the soap header message, you can set nodes with that information. So, each time the client consume a web service, he/she must athuenticate him/her self. Now, the problem is that don't work forme. T-T

Check the exaple at the bottom, http://msdn.microsoft.com/es-es/library/8728chd5.aspx (in spanish)

Now, I did a web service that brings the user name seted inside the header, the problem is that is not founded.

This. is my web service:

MyWebService.asmx

Imports System.Web.Services
Imports System.Web.Services.Protocols
Imports System.ComponentModel

' Define a SOAP header by deriving from the SoapHeader base class.
Public Class Header : Inherits SoapHeader
Public Username As String
Public Password As String
End Class

' To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the following line.
<System.Web.Script.Services.ScriptService()> _
<System.Web.Services.WebService(Namespace:="http://tempuri_org/")> _
<System.Web.Services.WebServiceBinding(ConformsTo:=WsiProfiles.BasicProfile1_1)> _
<ToolboxItem(False)> _
Public Class MyWebService
' Add a member variable of the type deriving from SoapHeader.
Public myHeaderMemberVariable As Header

' Apply a SoapHeader attribute.
<WebMethod(), SoapHeader("myHeaderMemberVariable")> _
Public Function MyWebMethod() As String
' Process the SoapHeader.
Return myHeaderMemberVariable.Username
End Function
End Class

My test file:

test1.php

<?php
require_once('nusoap_0-7-3/lib/nusoap.php');
?>

<?php
$wsdl = 'http://localhost/ws/MyWebService.asmx?WSDL';
$method = 'MyWebMethod';
$params = array();
$client = new nusoap_client($wsdl, 'wsdl');
//$client->response_timeout = 600;

$client->soap_defencoding = 'UTF-8';
$client -> setHeaders('
<Header>
<Username>myUserName</Username>
<Password>myPassword</Password>
</Header>
');
$err = $client->getError();
//echo "<br/> proxyport =".htmlspecialchars($client->$proxyhost)."<br/>";

if ($err) {
echo '<h2>Error del contructor</h2><pre>' . $err . '</pre>';
echo '<h2>Debug:</h2><pre>' . htmlspecialchars($client->getDebug(), ENT_QUOTES) . '</pre>';
exit();
}
$result = $client->call($method, $params);

if ($client->fault) {
echo '<h2>Fault</h2><pre>'; print_r($result); echo '</pre>';
} else {
$err = $client->getError();
if ($err) {
echo '<h2>Error</h2><pre>' . $err . '</pre>';
} else {
echo '<h2>Result</h2><pre>'; print_r($result); echo '</pre>';
}
}
echo '<h2>Request</h2><pre>' . htmlspecialchars($client->request, ENT_QUOTES) . '</pre>';
?>
</body>
</html>

My Issue 0_o

[faultcode] => soap:Server

I just want that the web service return myUserName, that's it T-T
If it works I could set some encripted information. All your posts are wellcome.

I don't know if you will receive this message because this forum has been inactive for some time but I had problems too. What web server would you recommend that I use to transfer the SOAP header from .NET??

Thanks,
