Using Guzzle to consume SOAP

Question

I\'m loving the Guzzle framework that I just discovered. I\'m using it to aggregate data across multiple API\'s using different response structures. It\'s worked find with JSON

You can get Guzzle to send SOAP requests. Note that SOAP always has an Envelope, Header and Body.

    
    
        
            Test
        
    

The first thing I do is build the xml body with SimpleXML:

$xml = new SimpleXMLElement('');
$xml->addChild('Data', 'Test');

// Removing xml declaration node
$customXML = new SimpleXMLElement($xml->asXML());
$dom = dom_import_simplexml($customXML);
$cleanXml = $dom->ownerDocument->saveXML($dom->ownerDocument->documentElement);

We then wrap our xml body with the soap envelope, header and body.

$soapHeader = '';

$soapFooter = '';

$xmlRequest = $soapheader . $cleanXml . $soapFooter; // Full SOAP Request

We then need to find out what our endpoint is in the api docs.

We then build the client in Guzzle:

$client = new Client([
    'base_url' => 'https://api.xyz.com',
]);

try {
    $response = $client->post(
    '/DataServiceEndpoint.svc',
        [
            'body'    => $xmlRequest,
            'headers' => [
            'Content-Type' => 'text/xml',
            'SOAPAction' => 'https://api.xyz.com/DataService/PostData' // SOAP Method to post to
            ]
        ]
    );

    var_dump($response);
} catch (\Exception $e) {
    echo 'Exception:' . $e->getMessage();
}

if ($response->getStatusCode() === 200) {
    // Success!
    $xmlResponse = simplexml_load_string($response->getBody()); // Convert response into object for easier parsing
} else {
    echo 'Response Failure !!!';
}
