我正在构建一个使用soap的应用程序。
我正在使用Zend_Soap_Autodiscover进行WSDL生成，使用SoapClient和SoapServer来处理请求。
我遇到的问题是客户端不断提供VersionMismatch，即使服务器和客户端都设置为soap 1.1版。
我不知道如何解决这个问题，并且已经坚持了一段时间。所以任何帮助都会受到极大的关注。
我正在尝试在客户端调用更新方法：
public function update() {
$this->_soap = Soap_Client_General::getInstance();
try {
$this->_soap->fetchNewVersion();
} catch (Exception $e) {
var_dump($e);
}
}
然而，这给了我以下转储：
object(SoapFault)#12 (10) {
["message":protected]=>
string(13) "Wrong Version"
["string":"Exception":private]=>
string(0) ""
["code":protected]=>
int(0)

}
My Server的soaphandling正在Zend Framework Application的soap模块中进行。此模块中的所有控制器都从基本控制器类扩展。
My_Controller_Base_Soap
<?php
class My_Controller_Base_Soap extends My_Controller_Base {
protected $_uri;
public function __construct(\Zend_Controller_Request_Abstract $request, \Zend_Controller_Response_Abstract $response, array $invokeArgs = array()) {
parent::__construct($request, $response, $invokeArgs);
$this->_uri = $this->view->serverUrl() . $this->view->baseUrl('soap/');
//Disable Layout
$this->_helper->layout()->disableLayout();
$this->_helper->viewRenderer->setNoRender();
Application_Model_Log::log('Soap Module Called: ' . implode('-', $request->getParams()) . ' from: '. $_SERVER['REMOTE_ADDR'] , 'soap');
}
//Generates WSDL for given class
protected function handleWSDL($classname) {
$autodiscover = new Zend_Soap_AutoDiscover();
$autodiscover->setClass($classname);
$autodiscover->handle();
}
//Handles the soap requests for the giving location and classname
protected function handleSOAP($loc, $classname) {
try {
$options = array('uri' => 'urn:' . $classname,
'location' => $loc,
'soap_version' => SOAP_1_1,
'cache_wsdl' => WSDL_CACHE_NONE);
$server = new SoapServer(null, $options);
$server->setClass($classname);
$server->handle();
} catch (Exception $e) {
Application_Model_Log::log('SoapException: ' . $e->getMessage(), 'soap');
}
}
}
上面的类扩展自My_Controller_Base，而My_Controller_Base又从Zend_Controller_Action扩展
香皂/ GeneralController
<?php
class Soap_GeneralController extends My_Controller_Base_Soap {
const CLASS_OBJECT = 'Soap_Model_General';
public function indexAction() {
$this->handleSOAP($this->view->baseUrl('soap/general/wsdl'), self::CLASS_OBJECT);
}
public function wsdlAction() {
$this->handleWSDL(self::CLASS_OBJECT);
}
}
Zend_Soap_Autoloader使用一个类来生成wsdl代：
Soap_Model_General
<?php
class Soap_Model_General extends Soap_Model_Base_Abstract{
/**
* Retrieve new Version
*
* @return string
*/
public function fetchNewVersion(){
if (!$this->_authenticated)
throw new SOAPFault("Not Authenticated.", 401);
}
}
此类扩展自包含身份验证方法的抽象基类。
Soap_Model_Base_Abstract
<?php
abstract class Soap_Model_Base_Abstract {
/**
* This property represents authentication status
* @var boolean
*/
protected $_authenticated = false;
/**
* The site object
* @var Application_Model_Website
*/
protected $_website;
/**
* Authenticates the SOAP request. (This one is the key to the authentication, it will be called upon the server request)
*
* @param array
* @return array
*/
public function authenticate($login) {
if (!empty($login->siteid) && !empty($login->hash)) {
//Determain if credentials are correct
$found = false;
$website = Application_Model_Website::find($login->siteid);
if ($website instanceof Application_Model_Site) {
//Is the authentication hash is correct? (siteid, secretkey and remote ip correct?)
$hash = md5($website->id . $website->secretkey . $website->ip);
if ($hash == $login->hash) {
$found = true;
}
}
//Verify the send IP
if ($found && $website->ip == $_SERVER['REMOTE_ADDR']) {
//Accept authentication
$this->_authenticated = true;
//set Application_Model_Site to site property
$this->_website = $website;
return true;
} else {
throw new SOAPFault("Incorrect credentials.", 401);
}
} else {
throw new SOAPFault("Invalid authentication format. Values may not be empty and are case-sensitive.", 401);
}
}
}
基本上，当我接近我的WSDL时，我得到一个完美生成的WSDL。
接下来是将客户端连接到服务器。
客户的代码在这里：
Soap_Client_General
<?php
class Soap_Client_General extends Soap_Client_Abstract {
private static $instance = NULL;
public static function getInstance() {
//get config
$config = Zend_Registry::get('config');
$wsdl = $config->general->server->general . '/wsdl/';
if (!self::$instance) {
return parent::getInstance($wsdl);
}
return self::$instance;
}
}
Soap_Client_Abstract
<?php
abstract class Soap_Client_Abstract {
private function __construct() {
}
/**
* Return client instance or create intitial
*
* @return SoapClient
* @access public
*/
public static function getInstance($wsdl) {
$ns = "auth";
$config = Zend_Registry::get('config');
$siteid = $config->general->siteid;
$secretkey = $config->general->secretkey;
$hash = md5($siteid . $secretkey . $_SERVER['SERVER_ADDR']);
//Create our Auth Object to pass to the SOAP service with our values
$auth->siteid = $siteid;
$auth->hash = $hash;
$auth_vals = new SoapVar($auth, SOAP_ENC_OBJECT);
//The 2nd variable, 'authenticate' is a method that exists inside of the SOAP service
$authenticate = new SoapHeader($ns, 'authenticate', $auth_vals, false);
$client = new SoapClient($wsdl, array('cache_wsdl' => WSDL_CACHE_NONE, 'soap_version' => SOAP_1_1));
$client->__setSoapHeaders(array($authenticate));
return $client;
}
private function __clone() {
}
}
我希望我已经提供了足够的信息。我希望你能在这件事上给我一些指导。
