SOAP身份验证问题

Question

我对这个有点头疼。使用NuSOAP。

webservice有一个名为LOGIN的函数，它接受参数USER和PASSWORD。但是，无论我是尝试通过setCredentials进行身份验证还是通过使用参数调用函数，我所得到的只是同样的错误（对'null'的身份验证被拒绝）。这是我一直在玩的代码，在底部你会找到答案。

$client = new nusoap_client('http://user:pass@xx.xx.xx.xx:9999/service?wsdl', 'WSDL');

//tested including user and password
//$client = new nusoap_client('http://user:pass@xx.xx.xx.xx:9999/service?wsdl', 'WSDL');

//check if there were any instantiation errors, and if so stop execution with an error    message:
 $error = $client->getError();

 if ($error)
 {
   die("client construction error: {$error}\n");
 }

//authenticate to the service:

 $client->setCredentials('user', 'pass');

$param = array('user' => 'user',
           'password' => 'pass');

 $answer = $client->call('login', array('parameters' => $param), '', '', false, true);
