CWebServiceAction

Package system.web.services
Inheritance class CWebServiceAction » CAction » CComponent
Implements IAction
Since 1.0
Source Code framework/web/services/CWebServiceAction.php
CWebServiceAction implements an action that provides Web services.

CWebServiceAction serves for two purposes. On the one hand, it displays the WSDL content specifying the Web service APIs. On the other hand, it invokes the requested Web service API. A GET parameter named ws is used to differentiate these two aspects: the existence of the GET parameter indicates performing the latter action.

By default, CWebServiceAction will use the current controller as the Web service provider. See CWsdlGenerator on how to declare methods that can be remotely invoked.

Note, PHP SOAP extension is required for this action.

Property Details

classMap property
public array $classMap;

a list of PHP classes that are declared as complex types in WSDL. This should be an array with WSDL types as keys and names of PHP classes as values. A PHP class can also be specified as a path alias.

See Also

provider property
public mixed $provider;

the Web service provider object or class name. If specified as a class name, it can be a path alias. Defaults to null, meaning the current controller is used as the service provider. If the provider implements the interface IWebServiceProvider, it will be able to intercept the remote method invocation and perform additional tasks (e.g. authentication, logging).

service property read-only
public CWebService getService()

Returns the Web service instance currently being used.

serviceOptions property
public array $serviceOptions;

the initial property values for the CWebService object. The array keys are property names of CWebService and the array values are the corresponding property initial values.

serviceUrl property
public string $serviceUrl;

the URL for the Web service. Defaults to null, meaning the URL for this action is used to provide Web services. In this case, a GET parameter named serviceVar will be used to deteremine whether the current request is for WSDL or Web service.

serviceVar property
public string $serviceVar;

the name of the GET parameter that differentiates a WSDL request from a Web service request. If this GET parameter exists, the request is considered as a Web service request; otherwise, it is a WSDL request. Defaults to 'ws'.

wsdlUrl property
public string $wsdlUrl;

the URL for WSDL. Defaults to null, meaning the URL for this action is used to serve WSDL document.

Method Details

createWebService() method
protected CWebService createWebService(mixed $provider, string $wsdlUrl, string $serviceUrl)
$provider mixed the web service provider class name or object
$wsdlUrl string the URL for WSDL.
$serviceUrl string the URL for the Web service.
{return} CWebService the Web service instance
Source Code: framework/web/services/CWebServiceAction.php#127 (show)
protected function createWebService($provider,$wsdlUrl,$serviceUrl)
{
    return new CWebService($provider,$wsdlUrl,$serviceUrl);
}

Creates a CWebService instance. You may override this method to customize the created instance.

getService() method
public CWebService getService()
{return} CWebService the Web service instance
Source Code: framework/web/services/CWebServiceAction.php#114 (show)
public function getService()
{
    return $this->_service;
}

Returns the Web service instance currently being used.

run() method
public void run()
Source Code: framework/web/services/CWebServiceAction.php#83 (show)
public function run()
{
    $hostInfo=Yii::app()->getRequest()->getHostInfo();
    $controller=$this->getController();
    if(($serviceUrl=$this->serviceUrl)===null)
        $serviceUrl=$hostInfo.$controller->createUrl($this->getId(),array($this->serviceVar=>1));
    if(($wsdlUrl=$this->wsdlUrl)===null)
        $wsdlUrl=$hostInfo.$controller->createUrl($this->getId());
    if(($provider=$this->provider)===null)
        $provider=$controller;

    $this->_service=$this->createWebService($provider,$wsdlUrl,$serviceUrl);

    if(is_array($this->classMap))
        $this->_service->classMap=$this->classMap;

    foreach($this->serviceOptions as $name=>$value)
        $this->_service->$name=$value;

    if(isset($_GET[$this->serviceVar]))
        $this->_service->run();
    else
        $this->_service->renderWsdl();

    Yii::app()->end();
}

Runs the action. If the GET parameter serviceVar exists, the action handle the remote method invocation. If not, the action will serve WSDL content;
