How do I see the actual XML generated by PHP SOAP Client Class?

Question

Consider this example SOAP Client script:

$SOAP = new SoapClient($WDSL); // Create a SOAP Client from a WSDL

// Build an array of data to send in the reques         


        

Answer 1

Extending Quinn's answer, you can also just log the request before you perform the request.

class SoapClientDebug extends SoapClient
{

public function __doRequest($request, $location, $action, $version, $one_way = 0)
{
    error_log("REQUEST:\n" .$request . "\n");
    error_log("LOCATION:\n" .$location . "\n");
    error_log("ACTION:\n" .$action . "\n");
    error_log("VERSION:\n" .$version . "\n");
    error_log("ONE WAY:\n" .$one_way . "\n");

    return parent::__doRequest($request, $location, $action, $version, $one_way);
}
}

Answer 2

if you are running the client locally, Fiddler is a great implementation agnostic way of looking at the messages on the wire.

If you are running it remotely then you could use something like Apache TCPMON Standalone or through eclipse*

The problem with Quinn Comendant's answer, that $request from __doRequest() will then be processed by __call() and the user will see an array of parameters instead of real xml request. To prevent this, such workaround can be used:

class DummySoapClient extends SoapClient {
    function __construct($wsdl, $options) {
        parent::__construct($wsdl, $options);
    }

    function __doRequest($request, $location, $action, $version, $one_way = 0) {
        throw new Exception($request);
    }

    function __call($function_name, $arguments)
    {
        try {
            parent::__call($function_name, $arguments);
        } catch (Exception $e) {
            return $e->getMessage();
        }
    }
}

Option trace is not necessary here, because we do not call __getLastRequest() or other relevant functions.

Answer 4

Use getLastRequest. It returns the XML sent in the last SOAP request.

echo "REQUEST:\n" . $SOAP->__getLastRequest() . "\n";

And remember, this method works only if the SoapClient object was created with the trace option set to TRUE. Therefore, when creating the object, use this code:

$SOAP = new SoapClient($WDSL, array('trace' => 1));

Answer 5

You need to enable tracing when you create your SoapClient. Like so:

$SOAP = new SoapClient($WSDL, array('trace' => true));

$Data = array('Something'=>'Some String','SomeNumber'=>22); 

Then call the __getLastRequest method after you've made a service call to see the XML.

$Response = $SOAP->DoRemoteFunction($Data);
echo $SOAP->__getLastRequest();

This will output the request XML.

Answer 6

$SOAP = new SoapClient($WSDL, array('trace' => true));

$Response = $SOAP->DoRemoteFunction($Data);

echo "REQUEST:\n" . htmlentities($SOAP->__getLastRequest()) . "\n";

This will not only print the last request but also make the XML tags visible in the browser.
