PHP SoapServer对函数返回空响应，不返回

Question

我有一个肥皂，它的方法什么也不返回

class mySoapService {
   foo(){

   }
}

$wsdl = ...;

$soapService = new mySoapService();

$soapServer = new \SoapServer($wsdl);
$soapServer->setObject($soapService);
$soapServer->handle(); // write nothing on call foo

一些肥皂客户端引发异常，因为他们期望正确的xml-soap空响应，如下所示：

<?xml version="1.0"?>
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/">
    <SOAP-ENV:Body SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">
    </SOAP-ENV:Body>
</SOAP-ENV:Envelope>

问题是：

1. 为什么PHP SoapServer返回空响应而不是xml-soap空响应？

2. 怎么说肥皂标准而不返回值？

Answer 1

更改

$soapServer->handle();

到

$soapServer->handle(file_get_contents("php://input"));

为我工作
