DocumentLiteralWrapper return Unknown error

[dmarczydlo]

I try to wrap zend-soap server response to DocumentLiteral

My code:

$options = array('uri' => 'http://localhost/server', 'soap_version' => SOAP_1_2);               
$soap = new \Zend\Soap\Server(null, $options);
$service = new \App\Services\SOAPVendorAPI();
$soap->setObject(new \Zend\Soap\Server\DocumentLiteralWrapper($service));
$response = $soap->handle();

as a response I receive

<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
   <SOAP-ENV:Body>
      <SOAP-ENV:Fault>
         <faultcode>Receiver</faultcode>
         <faultstring>Unknown error</faultstring>
      </SOAP-ENV:Fault>
   </SOAP-ENV:Body>
</SOAP-ENV:Envelope>

When I tried to debug this issue based on $soap->setReturnResponse(true); the response was:

Unfortunately $soap->setObject($service) ; working correcttly (without DocumentLiteralWrapper`

Can you provide the implementation of $service by any chance? Since zend-soap uses Reflection heavily, the only way we can really debug what's happening is to know what the DcoumentLiteralWrapper will be delegating to.

@weierophinney my service is a examle

[dmarczydlo]

@weierophinney sure:

$services is an object of the following class :

<?php

namespace App\Services;


class SOAPVendorAPI
{  
    use NewsService;
}

And trait:

<?php

namespace App\Services;

use \App\Repositories\NewsRepository;

trait NewsService
{
    /**
     * This function return news ...
     *
     * @param integer $offset
     * @param string  $limit
     * @return array
    */

    public function getNews($offset, $limit)
    {
        $news = NewsRepository::getListOfNews($offset, $limit);
        return $news;
    }

     /**
     * This function return calc ...
     *
     * @param integer $a
     * @param string  $b
     * @return int
    */

    public function calc($a, $b) {
        return $a + $b;
    }
}

It's a super simple class. I'm confused about why DocumentLiteralWrapper doesn't work correctly.

Also, I don't know why the response is not a SOAP_1_2 standard:

<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
   <SOAP-ENV:Body>
      <SOAP-ENV:Fault>
         <faultcode>Receiver</faultcode>
         <faultstring>Unknown error</faultstring>
      </SOAP-ENV:Fault>
   </SOAP-ENV:Body>
</SOAP-ENV:Envelope>

It looks like SOAP_1_1
