SOAP Client over HTTPS with SSL certificates on both sides - php

Question

I have to develop a SOAP Client, and the supplier send me this specifications:
Will be transmited using HTTPS through IP, and will be Packaged as XML documents that adjust to the diferent defnitions of XML scheme.
The Communications is synchronous, the third party should wait for response.
Each request and response will be signed.
I'm using the soapClient class from PHP, and all works fine, except when I try to use my private key to establish communication with the server:
Code: WSDL | Message: SOAP-ERROR: Parsing WSDL: Couldn't load from 'https://remoteserver/CustomerManagementService?wsdl' : failed to load external entity "https://remoteserver/CustomerManagementService?wsdl
Then I tried creating a .pem file, it contains my private key concatenated with my certificate, as I've read in: how to send SOAP request with SSL certificate in PHP?
But it still returns an error:
SOAP-ERROR: Parsing WSDL: Couldn't load from 'http://remoteserver:80/CustomerManager/proxy/CustomerManagementService?WSDL%2FGWTCommonResources%2Fwsdl%2FGWTCommonMessages' : failed to load external entity "http://remoteserver:80/CustomerManager/proxy/CustomerManagementService?WSDL%2FGWTCommonResources%2Fwsdl%2FGWTCommonMessages
I wonder if there is some way to get exactly the raw data that is being sent by the soapClient class of PHP. And where I must set the certificate of the supplier.
I've already tried with "$client->__getLastRequest()", but I'm getting a NULL. This is my code:
$client = new anotherSoapClient($service, array(
'local_cert' => $pem,
'style' => SOAP_RPC,
'use' => SOAP_ENCODED,
'soap_version' => SOAP_1_2,
'authentication'=> SOAP_AUTHENTICATION_DIGEST,
'ssl' => array(
'ciphers'=> "SHA1",
'verify_peer' => false,
'allow_self_signed' => true
),
'https' => array(
'curl_verify_ssl_peer' => false,
'curl_verify_ssl_host' => false
),
'cache_wsdl' => WSDL_CACHE_NONE,
'cache_ttl' => 86400,
'trace' => true,
'exceptions' => true,
));
// Test connection
echo BR.'Functions: <pre>';var_dump($client->__getFunctions());echo '</pre>';
$XMLrequest = $client->prepareRequest($email);
$response = $client->__anotherRequest('getCustomerInfo', $XMLrequest);
echo "REQUEST:\n" . $client->__getLastRequest() . "\n";
By the way, I'm using PHP 5.4.9 on my local machine and the server have PHP 5.3.10 and anotherSoapClient is a class who extend PHP soapClient class: PHP soapClient send custom XML

Answer 1

For debugging proposals your SOAP request you have to extend the SoapClient class.
class SoapClientDebug extends SoapClient
{
public function __doRequest($request, $location, $action, $version, $one_way = 0)
{
// Add code to inspect/dissect/debug/adjust the XML given in $request here
// Uncomment the following line, if you actually want to do the request
// return parent::__doRequest($request, $location, $action, $version, $one_way);
}
}
And next use it in your request:
$client = new SoapClientDebug("x.wsdl");
$response = $client->__soapCall($function);
echo $client->__getLastRequest();
Hope it helps to debug your code!

You probably need to specify following SoalClient options:
$defaultEndpoint = "https://remoteserver/CustomerManagementService";
$uri = "https://remoteserver";
$client = new anotherSoapClient($service, array(
'local_cert' => $pem,
'location' => $defaultEndpoint,
'uri' => $uri,
'style' => SOAP_RPC,
'use' => SOAP_ENCODED,
'soap_version' => SOAP_1_2,
'authentication'=> SOAP_AUTHENTICATION_DIGEST,
'ssl' => array(
'ciphers'=> "SHA1",
'verify_peer' => false,
'allow_self_signed' => true
),
'https' => array(
'curl_verify_ssl_peer' => false,
'curl_verify_ssl_host' => false
),
'cache_wsdl' => WSDL_CACHE_NONE,
'cache_ttl' => 86400,
'trace' => true,
'exceptions' => true,
));
