Soap/Wsdl loginhandler

Tuesday 22 December 2009 5:44:45 pm

make sure you have php soap extension installed. curl is a bonus, and needed you have to use https.

get the ggwebservices extension

decompress it in the 'extension' folder

go to admin interface, 'setup/extensions' page and activate it

create somewhere an override file for wsproviders.ini, where you put the ip address and details of your soap server and give it a name that you will later used in your code

create an extension, inside that create a new login handler. Take code from kernel/calsses/datatypes/ezuser/ezldapuser.php as an example. If you do not find docs about creating an extension with a login handler, take an existing extension that does that as an example (search for it on projecst.ez.no)

the code for the login handler will need at some point to use the static method ggeZWebservicesClient::send() to call the soap service

This error means that the xmlrpc client received something back from the server that is not valid xml. Most likely you are using a wrong url for your xmlrpc server, or you have some authentication problem.

To get more information about what is going on:

- increase the logging level, overriding the value for generalSettings/Logging in wsproviders.ini (set it to info)

- look at the log file: var/$siteaccess/log/webservices.log

else
{
print( "Returned SOAP value was: \"" . $response->value() . "\"" );
}


?>

this my client side code can u say what is the problem in this code.

<?php
include_once( "/var/www/OSCAR/extension/ggwebservices/classes/ggxmlrpcserver.php" );
include_once( "/var/www/OSCAR/extension/ggwebservices/classes/ggxmlrpcrequest.php" );
$server = new ggXMLRPCServer();
$server->registerFunction( "addNumbers", array( "valueA" => "int", "valueB" => "int"));
$server->processRequest();
function addNumbers($valueA, $valueB)
{

$return = $valueA + $valueB;
settype( $return, "int" );
return $return;
}

?>

admin side code.

Can u say what is the problem in this code.

By writing logging='info' its not creating the log file.

@namita: I am under the impression that you are trying to use the ggwebservices code outside of the scope of the eZ Publish application.

If it is so, I am afraid to tell you that this is not within the goals of ggwebservices: it has been developed as an extension to the eZPublish CMS, and there is no guarantee at all that it will ever work if used standalone. It might, but it also might not - and I cannot promise to have any time to dedicate to fix any errors you encounter for such a use case.

In particular, the webservices client classes might work, but the webservices server classes need an eZPublish server to work at all.

If you just want to execute xmlrpc or jsonrpc calls, or received those calls in a php app outside of eZPublish the phpxmlrpc extension available of http://phpxmlrpc.sourceforge.net might be a better fit.

If you want to execute or receive soap calls in a php app outside of eZPublish, the NuSOAP extension or simply the php native soap support might be a better fit.

Last but not least, answering to the question "How can i integrate ggwebservices in ASP.NET?": surely not by using classes that have XMLRPC in their name. Try using the ones that have SOAP in it.

And here is the working server - basically your code was fine

<?php
/**
 * Sample xmlrpc server that uses the ggws classes
 */

include_once( "ggwebservices/classes/ggwebservicesserver.php" );
include_once( "ggwebservices/classes/ggxmlrpcserver.php" );
include_once( "ggwebservices/classes/ggwebservicesrequest.php" );
include_once( "ggwebservices/classes/ggxmlrpcrequest.php" );
include_once( "ggwebservices/classes/ggwebservicesresponse.php" );
include_once( "ggwebservices/classes/ggxmlrpcresponse.php" );
include_once( "ggwebservices/classes/ggwebservicesfault.php" );

$server = new ggXMLRPCServer();
$server->registerFunction( "examples.addtwo", array( "valueA" => "int", "valueB" => "int" ) );
$server->processRequest();

function examples_addtwo($valueA, $valueB)
{
    $return = (int)$valueA + (int)$valueB;
    return $return;
}
 
?>

To test if there is any fatal errors, just browse to the server page with a browser. If you get an xml response with an error message, it's ok. If you get a blank page or a php errpr msg, it is not.

NB: a visual debugger (ie. xmlrpc client) is available within the eZ Publish administration interface, when you use the extension within the CMS

my server.php is

<?php
include_once( "ggjsonrpcserver.php" );
$server = new ggJSONRPCServer();
$server->registerFunction( "addNumbers", array( "valueA" => "integer", "valueB" => "integer"),"integer");
$server->processRequest();
function addNumbers($valueA, $valueB)
{
$return = (int)$valueA + (int)$valueB;
return $return;
}
?>

When i add parameters in payload in visual ws debugger in jsonrpc

as <param>
<value><int>45</int></value>
</param>
<param>
<value><int>78</int></value>
</param>

then, i got a error.

{"result":null,"error":{"faultCode":-201,"faultString":"Request received from client is not valid according to protocol format"},"id":null}

And if i run this page from browser it ask for save the page.

Thanks
