HHVM 上的 SoapServer 抛出"Bad Request" SoapFault

Question

我正在Hacklang中创建一个Soap web服务，在进行一些测试时，我注意到在某些情况下我会收到SoapFault-Bad Request。为了找出问题所在，我在php中编写了简化的类，并准备了适当的wsdl文件。经过一些测试，我发现在纯非hhvm php中，它工作得很好，但当我在hhvm上运行它时，它并没有像预期的那样工作——对于一些请求，它工作，而对于其他请求（只是有点不同），它抛出SoapFault。

soap.php:

<?php
if (isset($_GET['wsdl'])) {
    header('Content-Type:application/xml');
    echo file_get_contents('soap.wsdl');
    exit(0);
}
class WebService {
    public function addContacts($addContactsRequest) {
        return new SoapVar(
            array(
                'status'        => 0,
                'contactsCount' => 4,
            ),
            constant('SOAP_ENC_OBJECT'),
            'AddContactsResponse',
            'https://example.com/api/soap/'
        );
    }
}
$server = new SoapServer('soap.wsdl');
$server->setClass('WebService');
$server->handle();

soap.wsdl:

这些请求之间的唯一区别是第二个请求中多了一个<item xsi:type="ns1:Contact">...</item>元素。

Answer 1

我发现这是SoapServer::handle方法在没有参数（$soap_request）的情况下调用时的问题。如果我通过$HTTP_RAW_POST_DATA:，它可以正常工作

global $HTTP_RAW_POST_DATA;
$server->handle($HTTP_RAW_POST_DATA);
