// Based on http://stackoverflow.com/questions/3934639/soap-authentication-with-php
include 'auth.php';
$soapURL = "http://traindata.njtransit.com:8090/NJTTrainData.asmx?WSDL" ;
$soapParameters = array('UserCredentials'=>array('userName' => $username, 'password' => $password));

$soapFunction = "getTrainScheduleJSON" ;
$soapFunctionParameters = Array('station' => "NY") ;

$soapClient = new SoapClient($soapURL, $soapParameters);

$soapResult = $soapClient->__soapCall($soapFunction, $soapFunctionParameters);

这是输出（下）。它抱怨缺少必需的标头“UserCredentials”，但我包含了 UserCredentials。还是我错过了什么？谢谢！

这是在 __setSoapHeaders 之前添加 SoapHeader 的另一种尝试。我还添加了命名空间（$ns）：

include 'auth.php';
$soapURL = "http://traindata.njtransit.com:8090/NJTTrainData.asmx?WSDL" ;
$ns = 'http://microsoft.com/webservices/'; //Namespace of the WS.
$soapParameters = array('UserCredentials'=>array('userName' => $username, 'password' => $password));

$soapFunction = "getTrainScheduleJSON" ;
$soapFunctionParameters = Array('station' => "NY") ;

// $soapClient = new SoapClient($soapURL, $soapParameters);
$soapClient = new SoapClient($soapURL);

$header = new SoapHeader($ns,'UserCredentials',$soapParameters,false);

$soapClient->__setSoapHeaders($header);
var_dump($soapClient);
$soapResult = $soapClient->__soapCall($soapFunction, $soapFunctionParameters);

这是输出，新的错误消息是“对象引用未设置为对象的实例”。

}

你快到了，这条线：

$header = new SoapHeader($ns,'UserCredentials',$soapParameters,false);

已经创建了UserCredentials节点，所以这一行：

$soapParameters = array('UserCredentials'=>array('userName' => $username, 'password' => $password));

可以/应该是：

$soapParameters = array('userName' => $username, 'password' => $password);

这给了你一个空的响应，因为你调用函数的方式，你有两种可能的方式：

//1. add an extra array around params
$soapClient->__soapCall($soapFunction, array($soapFunctionParameters));
//2. or call like this:
$soapClient->$soapFunction($soapFunctionParameters);

（这仍然给我一个空的响应，但我认为那是因为我没有有效的凭据，这是需要注意的事情：我预计会出现soaperror/soapfault，但显然该服务不会在错误的凭据上生成它们） .
