Help using SOAP for login

Question

I'm designing a website for an organization that's a state chapter of a national organization. The national organization has implemented a member login that I need to use for the state website.

My website is in PHP, and it looks like the server for the national organization is using SOAP and ColdFusion. I'm a total newbie to using SOAP, so I'm probably missing a bunch of things.

The national organization sent me this information:

Fields to collect on a form
mausername
mapassword

Static variables
componenttype Value: Chapter
components Value: NM
authusername Value: NMChap
authpassword Value: USA
authpagealias Value: Login

The webservice is located here: https://www.apta.org/AM/APTAAPPS/ComponentAuthWebService/aptamemberauthorize.cfc?WSDL

The following fields will be returned: Email, FirstName, LastName, LoggedIn, Phone_Release, UserName

If LoggedIn returns “true,” the member has been authenticated as a member of the component.

This has been implemented and tested here: http://aptadevisg.apta.org/am/aptaapps/test/NM_Chap_test_form.cfm

Based on this information and reading the SOAP documentation, this is what I came up with:

$apta_server = 'https://www.apta.org/AM/APTAAPPS/ComponentAuthWebService/aptamemberauthorize.cfc?WSDL';

$post_data['mausername'] = '107150';
$post_data['mapassword'] = 'barnes';
$post_data['componenttype'] = 'Chapter';
$post_data['components'] = 'NM';
$post_data['authusername'] = 'NMChap';
$post_data['authpassword'] = 'USA';
$post_data['authpagealias'] = 'Login';

$options = array('trace' => 1, 'exceptions' => 0);
$options['location'] = 'https://www.apta.org/AM/APTAAPPS/ComponentAuthWebService/MemberAuth';

try
{
    $client = new soapclient($apta_server, $options);
}
catch (Exception $e)
{

}

$client->debug_flag = 1;

try
{
    $result = $client->__soapCall('MemberAuth', array($post_data));

    echo '<h1>Soap Result</h1><pre>';
    print_r($result);
    echo '</pre>';
}
catch (SoapFault $fault)
{
    echo '<h1>Soap Fault</h1><pre>';
    print_r($fault);
    echo '</pre>';
}

echo '<pre>getFunctions<br>';
print_r($client->__getFunctions());
echo '</pre>';

echo '<pre>getTypes<br>';
print_r($client->__getTypes());
echo '</pre>';

echo '<pre>getLastResponseHeaders<br>';
print_r($client->__getLastResponseHeaders());
echo '</pre>';

echo '<pre>getLastResponse<br>';
print_r($client->__getLastResponse());
echo '</pre>';

When I print out the result of the __soapCall(), I get a message of: "looks like we got no XML document."

I really don't know what I'm doing regarding SOAP, so any help would be greatly appreciated. You can view the results of the test login attempt at: http://rc19.info/test_login.php

Answer 1

First, you have the $options['location'] wrong. Try the location of the actual web service:

$options['location'] = 'https://www.apta.org/AM/APTAAPPS/ComponentAuthWebService/aptamemberauthorize.cfc';

Second, though not necessary, you don't have to call $client->__call("MemberAuth"). You can do $client->MemberAuth() and pass the parameters in like so:

$result = $client->MemberAuth($post_data['mausername'],$post_data['mapassword'],$post_data['componenttype'],$post_data['components'],$post_data['authusername'],$post_data['authpassword'],$post_data['authpagealias']);

Answer 2

You've got a superfluous array in there (you could see that with $client->__lastRequest(), so change:

$result = $client->__soapCall('MemberAuth', array($post_data));

To:

$result = $client->__soapCall('MemberAuth', $post_data);

After that, I get either an 'could not connect to host' (if I follow the port of the WSDL, https://aptaweb.apta.org/AM/APTAAPPS/ComponentAuthWebService/aptamemberauthorize.cfc), or a redirect (302) to the website with a bunch of cookies set if I choose yours (https://www.apta.org/AM/APTAAPPS/ComponentAuthWebService/MemberAuth). Use a stream_context with $context = stream_context_create(array('http'=>array('max_redirects'=>1))); and $client->__getLastRequestHeaders(); to see the redirect in action.

Curiously enough, Bob's solution of https://www.apta.org/AM/APTAAPPS/ComponentAuthWebService/aptamemberauthorize.cfc works, but is in no way indicated by the wsdl itself as far as I can tell.
