Question

Been having major issues trying to solve this issue, I’ll be happy to give a +500 bounty to someone who can help me get this work.

Basically, I’m trying to call this web service using Nusoap:

https://www.eway.com.au/gateway/ManagedPaymentService/managedCreditCardPayment.asmx?op=QueryCustomer

This is what I’ve got so far:

class Eway
{
    var $username = '[e-mail]';
    var $pw = 'test123';
    var $customerId = '87654321';
    private function setHeaders($client)
    {
        $headers = <<<EOT
<eWAYHeader xmlns="http://www.eway.com.au/gateway/managedPayment">
      <eWAYCustomerID>$this->customerId</eWAYCustomerID>
      <Username>$this->username</Username>
      <Password>$this->pw</Password>
    </eWAYHeader> 
EOT;
       $client->setHeaders($headers);
       return $client;
    }

     function getCustomer($ewayId = 9876543211000)
     {
        $url = 'https://www.eway.com.au/gateway/ManagedPaymentService/managedCreditCardPayment.asmx?WSDL';  
        $client = new Nusoap_client($url, true);
        $this->setHeaders($client);

        $args['QueryCustomer'] = array('managedCustomerID'=>$ewayId);

        $result = $client->call('QueryCustomer', $args);
        print_r($result);
    }
}

When I run this code and do $eway->getCustomer() I get the following error:

Array
(
    [faultcode] => soap:Client
    [faultstring] => eWayCustomerID, Username and Password needs to be specified in the soap header.
)

What am I doing wrong?

If you could fix my class and give me working code which is able to do the QueryCustomer method using the test customer id and return its info, I’ll be glad to give you +500 rep and my eternal gratitude. Obviously it’ll be 48 hours before I can start the bounty, but I promise that I will do it.

Answer 1

I could be missing the point, but you never actually assign the returned object to $client:

function getCustomer($ewayId = 9876543211000)
 {
    $url = 'https://www.eway.com.au/gateway/ManagedPaymentService/managedCreditCardPayment.asmx?WSDL';  
    $client = new Nusoap_client($url, true);
    $client = $this->setHeaders($client);

    $args['QueryCustomer'] = array('managedCustomerID'=>$ewayId);

    $result = $client->call('QueryCustomer', $args);
    print_r($result);
}

You could also set $client as a class variable if desired or by sending the parameter as a reference.

Looking at the data, I do not know if this matters, but you are using var for your class variable declarations and then using private for the function. If you are using php5 I would stay away from the var:

private $username = '[e-mail]';
private $pw = 'test123';
private $customerId = '87654321';

Use the private or public or protected (whichever your class requires) instead to keep consistency. I doubt this will solve your problem, just something to be conscious about.

Possible Solution

Ok, doing some digging of my own, figured this out, you need to encase the actual header you add in a SOAP:Header deal. I tested the below and it was working for me, so give it a try:

private function setHeaders($client)
{
    $headers = <<<EOT
<SOAP:Envelope xmlns:SOAP="http://schemas.xmlsoap.org/soap/envelope/" >
<SOAP:Header>
<eWAYHeader xmlns="http://www.eway.com.au/gateway/managedPayment">
  <eWAYCustomerID>$this->customerId</eWAYCustomerID>
  <Username>$this->username</Username>
  <Password>$this->pw</Password>
</eWAYHeader>
</SOAP:Header>
EOT;
   $client->setHeaders($headers);
   return $client;
}

It did not return any errors. So yea, it seems that is the likely culprit. (Note I also implemented the $client = $this->setHeaders($client); I mentioned above as well.

And my Final Answer is:

Alright did a bit of digging and found something that works. Not saying it is right, but yea it works.

private function setHeaders($client)
{
    $headers = <<<EOT
<eWAYHeader xmlns="https://www.eway.com.au/gateway/managedpayment">
  <eWAYCustomerID>$this->customerId</eWAYCustomerID>
  <Username>$this->username</Username>
  <Password>$this->pw</Password>
</eWAYHeader>
EOT;
   $client->setHeaders($headers);
   return $client;
}

 function getCustomer($ewayId = 123456789012)
 {
    $url = 'https://www.eway.com.au/gateway/ManagedPaymentService/managedCreditCardPayment.asmx?WSDL';
    $client = new nusoap_client($url);
    $client = $this->setHeaders($client);

    $args['QueryCustomer'] = array('managedCustomerID'=>$ewayId);

    $result = $client->call('QueryCustomer', $args, $namespace='https://www.eway.com.au/gateway/managedpayment', $soapAction='https://www.eway.com.au/gateway/managedpayment/QueryCustomer');

    print_r($result);

    //echo "\n{$client->request}\n"; // This echos out the response you are sending for debugging.
}

It seems the namespace and soapAction were the key ingredients. I found these using the link you originally posted: https://www.eway.com.au/gateway/ManagedPaymentService/managedCreditCardPayment.asmx?op=QueryCustomer

Basically, I just looked at that response, and then did some searching to figure out the soapAction, and then just messed with it until the request being sent matched the page you posted. It returns a failed login, but yea. That generally means something is working, and is probably due to the test data. But that gives you a baseline to go off of.

And the $client->request is a handy debugging tool for the future.
