Could not find any usable binding services in WSDL

Question

I'm trying to serve SOAP requests (QIWI payment system) with Kohana and PHP's SoapServer() class.

So I'm getting PHP Fatal error saying "SOAP-ERROR: Parsing WSDL: Could not find any usable binding services in WSDL."

my serving script is:

$s = new SoapServer(DOCROOT.'wsdls/IShopClientWS.wsdl');

My WSDL file is in http://mysite.url/wsdls/IShopClientWS.wsdl

It's content is:

Due to PHP-SOAP source files at http://lxr.sweon.net/php/http/source/ext/soap/php_sdl.c:

if (ctx.sdl->bindings == NULL || ctx.sdl->bindings->nNumOfElements == 0) {
                 soap_error0(E_ERROR, "Parsing WSDL: Could not find any usable binding services in WSDL.");
}

So, what's wrong with my WSDL file?

Would be very gratefull for any help!

Answer 1

At a glance, I would say SOAP 1.2 is not SOAP 1.1 (PHP's default). For 1.2 services, use:

$s = new SoapServer(DOCROOT.'wsdls/IShopClientWS.wsdl', 
        array('soap_version' => SOAP_1_2));

Also, transport should be "http://schemas.xmlsoap.org/soap/http" AFAIK, not http://www.w3.org/2003/05/soap/bindings/HTTP/.

<soap12:binding style="document" transport="http://schemas.xmlsoap.org/soap/http"/>

To be honest, I do not strictly know why, just that it is in my wsdl's and it just works. If anyone is masochistic enough to delve in the specs feel free to link to the relevant portion.

Here is some differencies between 1.1 and 1.2 specs: http://schemas.xmlsoap.org/wsdl/soap12/soap12WSDL.htm And there is no transport like http://www.w3.org/2003/05/soap/bindings/HTTP/ So my thoughts that this is just QIWI payment system bug.
