Good article on SOAP. Wondering whether we can see the WSDL file created by the autodiscovery. Any ideas !

Hello!

Thanks for the comment, you can see the WSDL file content, i created a simple
script for testing this example, it uses DOMDocument such that the XML is
printed with intendation. Otherwise you could only print $contents, it has no
linebreaks though:

ob_start();

$autodiscover = new Zend_Soap_AutoDiscover();
$autodiscover->setClass('HelloWorldService');
$autodiscover->handle();

$contents = ob_get_contents();
ob_end_clean();

$dom = new DOMDocument();
$dom->loadXML($contents);
$dom->formatOutput = true;
echo $dom->saveXML();

?>

Fantastic ! It works.

This was very usefull but I couldn't get it to work in 1.6.0 until this morning when 1.6.1 was available to download.
Thanks for a great intro though, one of the few dealing with the 1.6 version of ZF soap.

Hi.

I tried your solution, and I'm still getting, "Fatal error: Uncaught SoapFault exception: [VersionMismatch] Wrong Version in ..."

I need assistance as soon as possible.

thanks,

Hi,

Can you please explain how all of it fits in an MVC model? I do not want to hardcode URL locations of WSDL. I understand "HelloWorldService" class goes into models directory. But where will the code for autodiscovery of wsdl go?

Thanks

Also, can you please explain how to setup autodiscovery for multiple services?

Thanks

Hi,

Finally, a Zend Soap example that actually works. Thanks for that. Although, when i try to add a new function to the HelloWorldService, I got a Soap Exception: SoapFault exception: [Sender] Function ("getName") is not a valid method for this service. Can you help on this? Thank you.

hi,
i'm trying to use zend_soap but i cant do it work. i read your article and i just copy and paste it on my local server i it work. but you dont use zend_controller_action and the other stuffs. so i tried to use your code with it. it doesnt work. it gives a "Wrong Version" error. i tried many times and find i weird thing: if if put like this:

/**
* Renders WSDL
*/
public function wsdlAction() {
require_once APPLICATION_PATH."soap/ClassAPI.php";
$wsdl = new Zend_Soap_AutoDiscover();
$wsdl-setClass('ClassAPI');
$wsdl-handle();
exit;
}
it doesnt work (give me "Wrong Version" error), but if put like this:

/**
* Renders WSDL
*/
public function wsdlAction() {
if(isset($_GET["wsdl"])) {
require_once APPLICATION_PATH."soap/ClassAPI.php";
$wsdl = new Zend_Soap_AutoDiscover();
$wsdl-setClass('ClassAPI');
$wsdl-handle();
exit;
}
}
it doesnt work to, always return NULL values but dont give exceptions errors.

i dont know whats wrong.
do you already tried to do put this code inside a controller_action class? if yes could you send to me on my email to me analize it.

thank you

ps: im sorry for my english
pps: i already read http://electrotek.wordpress.com/2008/04/19/soap-web-service-with-zend-framework/ and it doesnt work to

Whenever you'll add methods to this example's class, you may want to check your Apache/PHP temp directory, since the WSDL is cached there. Delete it and *THEN* add new methods... it will work!

As an addition to my former post:
You can disable this feature by setting
soap.wsdl_cache_enabled=0
in your php.ini

Hey willian,
I had exactly the same problem as you.
If you look at the Zend API for Zend_Soap_Autodiscover you'll see that it says:

"As the SOAP Endpoint Uri is uses the default 'http://' .$_SERVER['HTTP_HOST'] . $_SERVER['SCRIPT_NAME'], but this can be changed with the setUri() function or the Constructor parameter of Zend_Soap_AutoDiscover class. The endpoint has to provide a Zend_Soap_Server that listens to requests."

ie using an MVC approach ZF thinks your webservice url is different from what it actually is. So, you have to call:
new Zend_Soap_AutoDiscover(true,url_of_your_webservice)

This isn't documented anywhere at all in the API. I had to look up these params in the class file itself. Yuk! But it did the trick for me.

Good luck!

Benjamin - Thanks for the SOAP intro, indeed! I am a PHP newbie.

My experience below, if it helps anybody...

I started with Zend_Soap_Server/Client with my Zend MVC bootstrapped way; I could not get it to work, so far (suspecting rewrite feature in .htaccess!). I then used (standard PHP) SoapServer & SoapClient (non-MVC, server defined under the web root), and used Zend_Auto_Discover to generate the WSDL. server & client uses this WSDL from PHP stdout. It worked ! Next, I got it working from a MVC client.

Thanks again, have a great one.

Great it works thank you

Hello when i try this example in zend framework then it will give "Wrong Version" exception.
so what should be the problems. can any one guide me here is my code

require_once realpath(APPLICATION_PATH . '/../library/').'/SoapDiscovery.class.php';
require_once realpath(APPLICATION_PATH . '/../library/').'/Soaptest.php';

{
private $_WSDL_URI = 'http://localhost/soap/public/soap/index?wsdl';

public function init()
{
}

public function indexAction()
{
$this->_helper->viewRenderer->setNoRender();

if(!isset($_GET['wsdl'])) {
//return the WSDL
$this->hadleWSDL();
} else {
//handle SOAP request
$this->handleSOAP();
}
}

private function hadleWSDL() {
$autodiscover = new Zend_Soap_AutoDiscover();
$autodiscover->setClass('Soaptest');
$autodiscover->handle();
}

private function handleSOAP() {
$soap = new Zend_Soap_Server($this->_WSDL_URI);
//print_r($soap);
$soap->setClass('Soaptest');
$soap->handle();
}

public function clientAction() {
try{

$client = new SoapClient('http://localhost/soap/public/soap/index');
echo '<pre>';
print_r($client->math_add(11,33));
// print_r($client->getname());
echo "hello";
exit;
/*$this->view->add_result = $client->math_add(11, 55);
