I'm preparing the SOAP server and generating my WSDL using the follow code:
//(... Controller action code ...)
if (key_exists('wsdl', $params)) {
$autodiscover = new AutoDiscover();
$autodiscover->setClass('WebServiceClass')
->setUri('http://server/webserver/uri');
$autodiscover->handle();
} else {
$server = new Server(null);
$server->setUri($ws_url);
$server->setObject($this->getServiceLocator()->get('MyController\Service\WebServiceClass'));
$server->handle();
}
//(... Controller action code ...)
But in one of my WebService method I have a parameter of type Array in which each element is of type "MyOtherClass", like follows:
/**
* Add list of MyOtherClass items
*
* @param MyOtherClass[] $items
*
* @return bool
*/
function add($items) {
// Function code here
}
When I try to generate the WSDL I get the follow error:
PHP Warning: DOMDocument::loadXML(): Empty string supplied as input in /<zend framweork path>/Server/vendor/zendframework/zendframework/library/Zend/Soap/Server.php on line 734
Or this Exception:
Cannot add a complex type MyOtherClass[] that is not an object or where class could not be found in "DefaultComplexType" strategy.
When I added to my code something like this:
//(...)
if (key_exists('wsdl', $params)) {
$autodiscover = new AutoDiscover();
$autodiscover->setClass('WebServiceClass');
$autodiscover->setUri($ws_url);
$complex_type_strategy = new \Zend\Soap\Wsdl\ComplexTypeStrategy\ArrayOfTypeComplex();
$complex_type_strategy->addComplexType('MyOtherClass');
$autodiscover->setComplexTypeStrategy($complex_type_strategy);
$autodiscover->handle();
} else {
//(...)
I get the follow error message:
Fatal error: Call to a member function getTypes() on a non-object in /<project dir>/vendor/zendframework/zendframework/library/Zend/Soap/Wsdl/ComplexTypeStrategy/AbstractComplexTypeStrategy.php on line 54
In resume, the question is: how can I make aware the WSDL of the new Custom Type used as parameter?
Thanks
I did something similar and this is a sample code:
/* code.... */
if (array_key_exists('wsdl', $this->request->getQuery()) || array_key_exists('WSDL', $this->request->getQuery())) {
$auto = new \Zend\Soap\AutoDiscover(new \Zend\Soap\Wsdl\ComplexTypeStrategy\ArrayOfTypeSequence());
$auto->setClass($controllerClassName);
$auto->setUri(sprintf('%s://%s%s', \Application\Bootstrap::getServiceManager()->get('config')[APPLICATION_ENV]['webServer']['protocol'],
$this->request->getUri()->getHost() , $this->request->getUri()->getPath()));
$auto->setServiceName(ucfirst($this->request->getModuleName()) . ucfirst($this->request->getControllerName()));
header('Content-type: application/xml');
echo $auto->toXML();
} elseif (count($this->request->getQuery()) == 0) {
$this->preDispatch();
$wsdl = sprintf('%s://%s%s?wsdl', \Application\Bootstrap::getServiceManager()->get('config')[APPLICATION_ENV]['webServer']['protocol'],
$this->request->getUri()->getHost() , $this->request->getUri()->getPath());
$soapServer = new \Zend\Soap\Server($wsdl);
$soapServer->setClass($controllerClassName);
$soapServer->handle();
}
/* code */
This is a fragment of the function signature of one of the classes that the autodiscover will generate the wsdl based on the annotations:
/**
* Allows to search for a patient based on the patient id
*
* @param int $id
* @return \ViewModels\PatientViewModel
* @throws \Application\Exception
*/
protected function searchPatientById($id) {
/* .... code */
This is the class \ViewModels\PatientViewModel and \ViewModel\DiagnosisViewModel Notice here how i used the annotations to declare that a field conatins an array of a complextype, and then how that is translated as ArrayOfDiagnosisViewModel on the wsdl
namespace ViewModels;
class PatientViewModel {
/**
* @var int
* */
public $id;
/**
* @var string
* */
public $firstname;
/**
* @var string
* */
public $lastname;
/**
*** @var \ViewModels\DiagnosisViewModel[]**
* */
public $diagnosis;
}
class DiagnosisViewModel {
/**
* @var int
*/
public $id;
/**
* @var string
*/
public $name;
}
And this is the WSDL generated

NOTICE THAT JUST BY CHANGING THE STRATEGY AND THE RIGHT DOCBLOCKS ANNOTATIONS YOU CAN ACHIEVE THAT.
