Question

我正在准备SOAP服务器并使用以下代码生成我的WSDL：

//(... 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 ...)

但是在我的一个WebService方法中，我有一个Array类型的参数，其中每个元素都是“MyOtherClass”类型，如下所示：

    /**
     * Add list of MyOtherClass items
     *
     * @param MyOtherClass[]    $items
     *
     * @return bool
     */
    function add($items) {
        // Function code here
    }

当我尝试生成WSDL时，我收到以下错误：

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

或者这个例外：

Cannot add a complex type MyOtherClass[] that is not an object or where class could not be found in "DefaultComplexType" strategy.

当我在代码中添加如下内容时：

//(...)
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 {
//(...)

我收到以下错误消息：

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

在简历中，问题是：我如何知道用作参数的新自定义类型的WSDL？

我做了类似的事情，这是一个示例代码：

/* 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 */

这是自动发现将根据注释生成wsdl的类之一的函数签名的片段：

/**
 * 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 */

这是类\ ViewModels \ PatientViewModel和\ ViewModel \ DiagnosisViewModel 请注意我如何使用注释声明一个字段包含一个复杂类型的数组，然后如何在wsdl上将其转换为ArrayOfDiagnosisViewModel

    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;

}

这是生成的WSDL

通知您只需更改策略以及您可以实现的正确的文件注释。

希望这些小册子可以帮助您找到解决方案。

Answer 2

万一有人从谷歌来到这里，想知道问题所在。

我发现这是因为docblock解析器不够智能，无法获取以不合格方式使用的类。例如：

<?php

use myNameSpace\MyClass;

class Foo
{
    /**
     * @var MyClass
     */ 
    public $customer;
}

不起作用。当Zend解析它时，它不会解析命名空间，只解析类名“MyClass”，然后失败。

你必须这样做：

<?php

class Foo
{
    /**
     * The backspace qualifier is only necessary if this is namespaced.
     * @var \myNameSpace\MyClass
     */ 
    public $customer;
}
