Each SOAP provider * is a class that implements a set of SOAP methods which are exposed * to SOAP clients for remote invocation. TSoapService generates WSDL * automatically for the SOAP providers by default. * * To use TSoapService, configure it in the application specification like following: * <code> * <services> * <service id="soap" class="System.Web.Services.TSoapService"> * <soap id="stockquote" provider="MyStockQuote" /> * </service> * </services> * </code> * * The above example specifies a single SOAP provider named "stockquote" * whose class is "MyStockQuote". A SOAP client can then obtain the WSDL for * this provider via the following URL: * <code> * http://hostname/path/to/index.php?soap=stockquote.wsdl * </code> * * The WSDL for the provider class "MyStockQuote" is generated based on special * comment tags in the class. In particular, if a class method's comment * contains the keyword "@soapmethod", it is considered to be a SOAP method * and will be exposed to SOAP clients. For example, * <code> * class MyStockQuote { * / ** * * @param string $symbol the stock symbol * * @return float the stock price * * @soapmethod * * / * public function getQuote($symbol) {...} * } * </code> * * With the above SOAP provider, a typical SOAP client may call the method "getQuote" * remotely like the following: * <code> * $client=new SoapClient("http://hostname/path/to/index.php?soap=stockquote.wsdl"); * echo $client->getQuote("ibm"); * </code> * * Each <soap> element in the application specification actually configures * the properties of a SOAP server which defaults to {@link TSoapServer}. * Therefore, any writable property of {@link TSoapServer} may appear as an attribute * in the <soap> element. For example, the "provider" attribute refers to * the {@link TSoapServer::setProvider Provider} property of {@link TSoapServer}. * The following configuration specifies that the SOAP server is persistent within * the user session (that means a MyStockQuote object will be stored in session) * <code> * <services> * <service id="soap" class="System.Web.Services.TSoapService"> * <soap id="stockquote" provider="MyStockQuote" SessionPersistent="true" /> * </service> * </services> * </code> * * You may also use your own SOAP server class by specifying the "class" attribute of <soap>. * * @author Knut Urdalen <knut.urdalen@gmail.com> * @author Qiang Xue <qiang.xue@gmail.com> * @package System.Web.Services * @since 3.1 */ class TSoapService extends TService { const DEFAULT_SOAP_SERVER='TSoapServer'; const CONFIG_FILE_EXT='.xml'; private $_servers=array(); private $_configFile=null; private $_wsdlRequest=false; private $_serverID=null; /** * Constructor. * Sets default service ID to 'soap'. */ public function __construct() { $this->setID('soap'); } /** * Initializes this module. * This method is required by the IModule interface. * @param TXmlElement configuration for this module, can be null * @throws TConfigurationException if {@link getConfigFile ConfigFile} is invalid. */ public function init($config) { if($this->_configFile!==null) { if(is_file($this->_configFile)) { $dom=new TXmlDocument; $dom->loadFromFile($this->_configFile); $this->loadConfig($dom); } else throw new TConfigurationException('soapservice_configfile_invalid',$this->_configFile); } $this->loadConfig($config); $this->resolveRequest(); } /** * Resolves the request parameter. * It identifies the server ID and whether the request is for WSDL. * @throws THttpException if the server ID cannot be found * @see getServerID * @see getIsWsdlRequest */ protected function resolveRequest() { $serverID=$this->getRequest()->getServiceParameter(); if(($pos=strrpos($serverID,'.wsdl'))===strlen($serverID)-5) { $serverID=substr($serverID,0,$pos); $this->_wsdlRequest=true; } else $this->_wsdlRequest=false; $this->_serverID=$serverID; if(!isset($this->_servers[$serverID])) throw new THttpException(400,'soapservice_request_invalid',$serverID); } /** * Loads configuration from an XML element * @param TXmlElement configuration node * @throws TConfigurationException if soap server id is not specified or duplicated */ private function loadConfig($xml) { foreach($xml->getElementsByTagName('soap') as $serverXML) { $properties=$serverXML->getAttributes(); if(($id=$properties->remove('id'))===null) throw new TConfigurationException('soapservice_serverid_required'); if(isset($this->_servers[$id])) throw new TConfigurationException('soapservice_serverid_duplicated',$id); $this->_servers[$id]=$properties; } } /** * @return string external configuration file.
