Hi,
I added the __setSoapHeader() to allow me to write a custom Binding
for eBay. I needed to be able to flow an eBay CustomSecurityHeader in
the SoapHeader. An extract of its use is as follows (I've modified
the code a little to show how you would use it directly on the proxy
rather than in a custom binding for clarity, but to preserve the
protocol/business logic separation, this is best done in a binding):
$requester_credentials =
$proxy-
>createDataObject('urn:ebay:apis:eBLBaseComponents',
'CustomSecurityHeaderType');
$requester_credentials->eBayAuthToken = $this-
>config['authtoken'];
$credentials = $requester_credentials-
>createDataObject('Credentials');
$credentials->AppId = $this->config['appid'];
$credentials->DevId = $this->config['devid'];
$credentials->AuthCert = $this->config['authcert'];
$proxy->__setSoapHeader($requester_credentials,
'urn:ebay:apis:eBLBaseComponents',
'RequesterCredentials');
$response = $proxy->GetSearchResults($request);
I think it would be good to provide the equivalent on the server
side. This would probably be best used by custom binding
implementations to keep header handling separate from business logic
(I'm not sure how this could be cleanly done any other way since an
SCA component does not know about the binding implementation, so can't
easily explicitly request the header).
Ideally the SoapServer would provide a hook for this to be
implemented, but unfortunately this is not the case (see
http://bugs.php.net/bug.php?id=38309). It may be possible to extend
the SCA_Bindings_ws_ServiceRequestHandler to parse out the header into
an SDO, but this will impact performance (the SoapServer has already
parsed the request once).
We may be able to request that the SoapServer provide the hook (or
offer to contribute it), if that's what we decide is the best way
forward.
