问题
Using the PHP5 SOAP extension I have been unable to connect to a web service having an https endpoint, with client certificate and using WS-Security, although I can connect using soapUI with the exact same wsdl and client certificate, and obtain the normal response to the request. There is no HTTP authentication and no proxy is involved. The message I get is 'Could not connect to host'. Have been able to verify that I am NOT hitting the host server. (Earlier I wrongly said that I was hitting the server.)
The self-signed client SSL certificate is a .pem file converted by openssl from a .p12 keystore which in turn was converted by keytool from a .jks keystore having a single entry consisting of private key and client certificate.
In soapUI I did not need to supply a server private certificate, the only two files I gave it were the wdsl and pem. I did have to supply the pem and its passphrase to be able to connect. I am speculating that despite the error message my problem might actually be in the formation of the XML request rather than the SSL connection itself.
The wsdl I have been given has nested complex types. The php server is on my Windows XP laptop with IIS.
The code, data values and WSDL extracts are shown below. (The WSSoapClient class simply extends SoapClient, adding a WS-Security Username Token header with mustUnderstand = true and including a nonce, both of which the soapUI call had required.)
Would so much appreciate any help. I'm a newbie thrown in at the deep end, and how! Have done vast amounts of Googling on this over many days, following many suggestions and have read Pro PHP by Kevin McArthur. An attempt to use classmaps in place of nested arrays also fell flat.
The Code
class STEeService
{
public function invokeWebService(array $connection, $operation, array $request)
{
try
{
$localCertificateFilespec = $connection['localCertificateFilespec'];
$localCertificatePassphrase = $connection['localCertificatePassphrase'];
$sslOptions = array(
'ssl' => array(
'local_cert' => $localCertificateFilespec,
'passphrase' => $localCertificatePassphrase,
'allow_self-signed' => true,
'verify_peer' => false
)
);
$sslContext = stream_context_create($sslOptions);
$clientArguments = array(
'stream_context' => $sslContext,
'local_cert' => $localCertificateFilespec,
'passphrase' => $localCertificatePassphrase,
'trace' => true,
'exceptions' => true,
'encoding' => 'UTF-8',
'soap_version' => SOAP_1_1
);
$oClient = new WSSoapClient($connection['wsdlFilespec'], $clientArguments);
$oClient->__setUsernameToken($connection['username'], $connection['password']);
return $oClient->__soapCall($operation, $request);
}
catch (exception $e)
{
throw new Exception("Exception in eServices " . $operation . " ," . $e->getMessage(), "\n");
}
}
}
$connection is as follows:
array(5) { ["username"]=> string(8) "DFU00050"
["password"]=> string(10) "Fabricate1"
["wsdlFilespec"]=>
string (63) "c:/inetpub/wwwroot/DMZExternalService_Concrete_WSDL_Staging.xml"
["localCertificateFilespec"]=> string(37)
"c:/inetpub/wwwroot/ClientKeystore.pem"
["localCertificatePassphrase"]=> string(14) "password123456" }
$clientArguments is as follows:
array(7) { ["stream_context"]=> resource(8) of type (stream-context)
["local_cert"]=> string(37) "c:/inetpub/wwwroot/ClientKeystore.pem"
["passphrase"]=> string(14) "password123456"
["trace"]=> bool(true) ["exceptions"]=> bool(true) ["encoding"]=> string(5) "UTF-8"
["soap_version"]=> int(1) }
$operation is as follows:
'getConsignmentDetails'
$request is as follows:
array(1) { [0]=> array(2) { ["header"]=> array(2) {
["source"]=> string(9) "customerA" ["accountNo"]=> string(8) "10072906" }
["consignmentId"]=> string(11) "GKQ00000085" } }
Note how there is an extra level of nesting, an array wrapping the request which is itself an array. This was suggested in a post although I don't see the reason, but it seems to help avoid other exceptions.
The exception thrown by ___soapCall is as follows:
object(SoapFault)#6 (9) { ["message":protected]=>

And here in case it's relevant is the WSSoapClient class:

';
$authvalues = new SoapVar($auth, XSD_ANYXML);
$header = new SoapHeader("http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd", "Security",$authvalues, true);
return $header;
}

{
try
{
$result = parent::__soapCall($function_name, $arguments, $options, $this->wssecurity_header());
return $result;
}
catch (exception $e)
{
throw new Exception("Exception in __soapCall, " . $e->getMessage(), "\n");
}
}
}

This was obtained with the following code in WSSoapClient:
public function __doRequest($request, $location, $action, $version) {
echo "<p> " . htmlspecialchars($request) . " </p>" ;
return parent::__doRequest($request, $location, $action, $version);
}

For anyone else struggling with the startrack API. Here is class I wrote to go via CURL instead.
Instructions:
Add the attached file to:
Client/Executables
Change line 28 from
class WSSoapClient extends SoapClient
To:
require('SoapClientCurl.class.php');
class WSSoapClient extends SoapClientCurl
<?php
/**
* Override to overcome problems with Startrack Self Signed SSL Certificates on
* certain server configurations.
*
* The important options here that aren't available in the SoapClient options are
* CURLOPT_SSLVERSION - Forces the SSl Version to 3
* CURLOPT_SSL_VERIFYHOST - Tells ssl not to care that the Startrack SSL certificate is for a different domain
* CURLOPT_SSL_VERIFYPEER - Tells ssl not to care that the Startrack SSL certificate is from a bogus CA (I think)
*
*/
class SoapClientCurl extends SoapClient
{
/**
*
* @param string $request - The XML SOAP request.
* @param string $location - The URL to request.
* @param string $action - The SOAP action.
* @param int $version - The SOAP version.
* @param boolean $one_way - If one_way is set to 1, this method returns nothing. Use this where a response is not expected.
* @throws SoapFault
* @return string|void
*/
public function __doRequest($request, $location, $action, $version, $one_way = 0)
{
$handle = curl_init();
curl_setopt($handle, CURLOPT_URL, $location);
curl_setopt($handle, CURLOPT_HTTPHEADER, array(
'Content-type: text/xml;charset="utf-8"',
'Accept: text/xml',
'Cache-Control: no-cache',
'Pragma: no-cache',
'SOAPAction: '.$action,
'Content-length: '.strlen($request))
);
curl_setopt($handle, CURLOPT_RETURNTRANSFER, true);
curl_setopt($handle, CURLOPT_POSTFIELDS, $request);

$response = curl_exec($handle);

回答2:
When I ran the code under Apache (using XAMPP) it worked first time. My problem must have been somewhere in the configuration of IIS or PHP.
There was one typo but it wasn't the showstopper:
'allow_self-signed' => true
should be
'allow_self_signed' => true
回答3:
Given the error message you've got AND the fact that you're hitting the target server, I'd guess that the SSL client certificate is screwing things up. I notice you're specifying this twice - once directly in the SOAP client params and once in the stream context - is this necessary? Have you tried omitting the stream context and using just the SoapClient params? Do you have to use a client certificate?
