Php 尝试SOAP调用时，对象引用未设置为对象错误的实例

我正在尝试使用SOAP/wsdl连接到Web服务并进行身份验证，但我经常遇到错误：

<b>Fatal error</b>:  Uncaught SoapFault exception: [a:InternalServiceFault] Object reference not set to an instance of an object. in /path/install.php:16

这给了我一个关于

LogOnType

不受支持的错误（用丹麦语，这对我来说意味着至少我现在已经与服务器建立了某种连接）。用户名和密码数组无效，我可以替换一个空字符串并得到相同的结果，不同之处在于小写的

logon

如果有人能建立一个工作示例，给出错误的

不正确的用户名或密码

我将永远感激。。。但是任何指针都将非常受欢迎

据我所知，wsdl提供了实现这一点所需的所有信息，我只是一个太多的

[你的选择]

，无法得到它…？

难以置信！写这16行代码只花了9个小时

<?php
header("Content-Type: text/plain"); 

$userinfo = array(
    'Username'=>'test',
    'Password'=>'test'
);

$wsdl_url = 'https://ws-e-distribution.kmd.dk/standard/ServiceAutorisation/ServiceAutorisation.svc?wsdl';
$client = new SoapClient($wsdl_url, array('trace' => 1, "exception" => 0));

print_r($client->__getFunctions());
print_r($client->__getTypes());

//This actually works ! :) :) :)
$response = $client->LogOn(array('logon' => new SoapVar($userinfo, SOAP_ENC_OBJECT, 'LogOnUsername', 'http://schemas.datacontract.org/2004/07/WebServiceAutorisation.BL')));

var_dump($response);

$response = $client->LogOn(array('logon' => array('Username' => 'test','Password' => 'test')));
