php - 在 PHP 7.4 中生成 SOAP 数组

Question

我一直在一个工作项目中使用 SOAP API(是的，我很幸运!)，WSDL 基本上没有意义，因为请求的主体是 <any />所以我必须生成 SOAP 请求而不是使用 classmap 选项。我正在使用这种方式https://www.fischco.org/technica/2011/php-soap/生成一个对象数组，否则，正如我在帖子中所说的那样，我得到了 <BOGUS>标签。
这几乎是我多年来的做法，从我所看到的例如 http://www.mm-newmedia.de/2017/10/php-und-bipro-sich-wiederholende-elemente-im-soap-request/ 看来，很多其他人也是这样做的。和 http://andrecatita.com/code-snippets/php-soap-repeated-element-name/
一切正常，但我意识到我仍在使用 7.3 docker 镜像，因此升级到 7.4 并且这不再有效，我只获取数组的标签而不是单个项目，我认为这是因为 7.4 中的此更改。

Calling get_object_vars() on an ArrayObject instance will now always return the properties of the ArrayObject itself (or a subclass). Previously it returned the values of the wrapped array/object unless the ArrayObject::STD_PROP_LIST flag was specified.

以前有人遇到过这个问题吗？我昨天整个下午都在试图弄清楚，但我完全被难住了
这是一个演示此行为的示例客户端

<?php

class Location
{
    public $Name;
}

// Overwrite the client so it doesn't actually make a request
class DebugSoapClient extends SoapClient
{
    public function __construct(string $wsdl, array $options = [])
    {
        $options = array_merge([
            'cache_wsdl'   => WSDL_CACHE_NONE,
            'exceptions'   => true,
            'features'     => SOAP_SINGLE_ELEMENT_ARRAYS,
            'soap_version' => SOAP_1_1,
            'trace'        => true,
        ], $options);

        parent::__construct($wsdl, $options);
    }

    public function __doRequest($request, $location, $action, $version, $one_way = 0): string
    {
        return '<?xml version="1.0" encoding="utf-8"?><soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"><soap:Body><SubmitWorkItemResponse xmlns="http://example.com/webservices/DataServices/v2/ServicesAccess"><SubmitWorkItemResult></SubmitWorkItemResult></SubmitWorkItemResponse></soap:Body></soap:Envelope>';
    }
}

// Create an instance of the client
$namespace = 'http://example.com/webservices/DataServices/v2/ServicesAccess';
$client = new DebugSoapClient(__DIR__ . '/example.wsdl');
$client->__setSoapHeaders(
    new SoapHeader(
        $namespace,
        'AuthenticationHeader',
        ['Username' => 'Foo', 'Password' => 'Bar', 'ClientName' => 'Baz']
    )
);

// Build the body of the request
$locations = new ArrayObject();
foreach (['London', 'New York', 'Paris', 'Rome'] as $l) {
    $loc = new Location();
    $loc->Name = new SoapVar($l, XSD_STRING, '', '', 'Name', $namespace);

    $locations->append(new SoapVar($loc, SOAP_ENC_OBJECT, '', '', 'Location', $namespace));
}

$request = [
    'SourceData' => [
        'any' => new SoapVar($locations, SOAP_ENC_OBJECT, '', '', 'Locations', $namespace)
    ],
];

// Dispatch the request
$client->__soapCall('SubmitWorkItem', [$request]);

// Get the request body
$doc = new DomDocument('1.0');
$doc->loadXML($client->__getLastRequest());
$doc->formatOutput = true;

echo $doc->saveXML();

这是一个简化的 WSDL

您只需要应用 1 个更改:

$request = [
    'SourceData' => [
        'any' => new SoapVar($locations->getArrayCopy(), SOAP_ENC_OBJECT, '', '', 'Locations', $namespace)
    ],
 ];
 // add this                           ^--------------^
