zend framework 提供的webservices,该如何处理

<br /><?php<br />class WebServiceController extends Zend_Controller_Action {<br />	public function init() {<br />    	$this->_helper->viewRenderer->setNoRender();<br />	}<br />	<br />	public function indexAction() {<br />		if (isset($_GET['wsdl'])) {<br />			$autodiscover = new Zend_Soap_AutoDiscover();	<br />		    $autodiscover->setClass('Service_Helloworld');<br />		    $autodiscover->handle();<br />		} else {<br />		    $soap = new Zend_Soap_Server("http://zf-demo.localhost/WebService/index/?wsdl");<br />		    $soap->setClass('Service_Helloworld');<br />		    $soap->handle();<br />		}<br />	}<br />	<br />	public function testAction() {<br />		$params = array(<br />			'name' => 'tom'<br />		);<br />		<br />		$client = new SoapClient("http://zf-demo.localhost/WebService/index/?wsdl", array('trace' => 1));<br />		echo $client->__soapCall('sayHello', $params);<br />	}<br />	<br />}<br />

<br /><?php<br />class Service_Helloworld {<br />	/**<br />	 * say hello<br />	 * @param string $name<br />	 * @return string<br />	 */<br />	public function sayHello($name) {<br />		return 'hello ' . $name;<br />	}<br />}<br />
