SOAP 身份验证问题

Question

我对这个有点头疼。使用 NuSOAP。

Web 服务有一个名为 LOGIN 的函数，它接受参数 USER 和 PASSWORD。但无论我尝试通过 setCredentials 还是通过使用参数调用函数进行身份验证，我不断收到的都是相同的错误（身份验证因“null”而被拒绝）。这是我一直在使用的代码，在底部你会找到响应。

$client = new nusoap_client('http://user:[email protected]:9999/service?wsdl', 'WSDL');

//tested including user and password
//$client = new nusoap_client('http://user:[email protected]: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);
