how to capture outgoing soapclient request?

Question

I've tried a couple of potential solutions (using ob_ for instance) I found, but not having any luck.

I'd like to be able to display to screen the outgoing request in order to debug it.

I've debugging of SoapClient by extending the SoapClient and overriding methods like _soapcall() and _doRequest(). In my projects I have a logger that writes the XML/arguements to a file.

My example includes both _soapCall() and _doRequest(). I print out different stuff in both methods. Might suit your debugging needs. I like to read the $args output from __soapCall() and like to copy the XML into SoapUI for validation (Alt+V). HTTP headers might also be interesting if you are debugging authentication or other error situations.

class MySoapClient extends SoapClient {
    public function __soapCall ($function_name, array $args, array $options = null, $input_headers = null, array &$output_headers = null) {
        // Dump $args to file, browser printout, console, etc
        var_dump($args);

        parent::__soapCall ($function_name, $args, $options, $input_headers, $output_headers);

        // XML request and response:
        var_dump($this->__getLastRequest()); // Request sent to server
        var_dump($this->__getLastResponse()); // Response from server

        // HTTP headers:
        var_dump($this->__getLastRequestHeaders());
        var_dump($this->__getLastResponseHeaders());
    }

    public function __doRequest ( string $request , string $location , string $action , int $version, int $one_way = 0 ) {
        var_dump($request); // XML

        $response = parent::__doRequest ($request, $location, $action, $version, $one_way);
        var_dump($response); // XML

        return $response;
    }
}

$webservice = new MySoapClient('http://example.com/myservice?wsdl');
$webservice->__soapCall('SomeOperation', array($someArguments));

A logger can be used instead for var_dump:

logger('debug', $this->__getLastRequest());
