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中写了简化的class，并准备了适当的wsdl文件。经过一些测试后，我发现在纯非 hhvm php 中它运行良好，但是当我运行它在 hhvm 上时它无法按预期工作 - 对于某些请求它可以工作，而对于其他 (只是有点不同）它会抛出 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 方法在不带参数调用时的问题 ($soap_request)。如果我通过 $HTTP_RAW_POST_DATA:

它工作正常

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

HHVM 上的 SoapServer 抛出 "Bad Request" SoapFault
