我在Hacklang中創建Soap Web服務，並在做一些測試時發現，在某些情況下，我收到SoapFault - Bad Request。爲了找出問題所在，我在php中編寫了簡化的類並準備了適當的wsdl文件。經過一些測試後，我發現在純非hhvm php中，它運行良好，但是當我在hhvm上運行它時，它無法按預期工作 - 對於某些請求它的工作原理，對於其他（僅有一點不同）它會拋出SoapFault 。HHVM上的SoapServer會拋出「Bad Request」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();
