SOAP Client receiving empty stdclass

问题

I don't understand why I am getting an empty stdclass object.

Here's the code:

$client = new Zend_Soap_Client('http://urltocodethatgenerateswsdl?wsdl', $options);
$result = $client->sayHello(array( 'who' => 'Heidi'));
Zend_Debug::dump($client->getLastResponse());
Zend_Debug::dump($result);

Here's what I get for the lastResponse:

<?xml version="1.0" encoding="UTF-8"?>
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ns1="http://urltocodethatgenerateswsdl">
    <SOAP-ENV:Body>
        <ns1:sayHelloResponse>
            <return>Say Hello Heidi</return>
        </ns1:sayHelloResponse>
    </SOAP-ENV:Body>
</SOAP-ENV:Envelope>

And here is the dump of $result

object(stdClass)#23 (0) {}

Why is that? Can somebody explain?

UPDATE: Added WSDL (automatically generated by Zend using AutoDiscovery)

回答1:

I found the reason why it wasn't working. I had to turn off caching in the config and add an option to not cache in the request I made.

Either disable caching by using ini_set, or by making a modification to your php.ini:

ini_set("soap.wsdl_cache_enabled", 0);

I also added the following option parameter to my request:

array('cache_wsdl' => WSDL_CACHE_NONE)

Here's an article I found on Stackoverflow: In PHP how can you clear a WSDL cache?

回答2:

It seems like this post discussed the same problem:

Return object with Zend_Soap

Citation:

You need to pass a 'classmap' option variable in the client. See both http://www.php.net/manual/en/soapclient.soapclient.php and http://www.php.net/manual/en/soapclient.soapclient.php about the 'classmap' option passed in the option array. Basically it should be an array mapping your classes to the classes defined as the returned objects in the WSDL file.
