PHP SOAP在请求中不包括我的参数

我正在尝试访问上的HelloWorldCredentials服务

https://statistik.uni-c.dk/instregws/DataServiceXML.asmx?op=HelloWorldCredentials

我有必要的证件

据我所知，我需要提交一个名为“Credentials”的数组，其中一个数组包含两个字符串，一个数组名为“Username”，另一个数组名为“Password”

我按如下方式构建阵列：

$params = array(
    "Credentials" => array(
        "Username" => "Obviously",
        "Password" => "NotPublic",
    )
);

然而，当我执行

$client = new SoapClient("https://statistik.uni-c.dk/instregws/DataServiceXML.asmx?wsdl", array('trace' => 1));
$params = array(
    "Credentials" => array(
        "Username" => "Obviously",
        "Password" => "NotPublic",
    )
);
$response = $client->__soapCall("HelloWorldCredentials", array($params));

echo("*** PARAMS ***\n");
var_dump( $params );

echo("\n*** REQUEST ***\n");
echo( $client->__getLastRequest() );

echo("\n*** RESPONSE ***\n");
var_dump( $response );

我明白了

-我应该这么做，但是

*** REQUEST ***
<?xml version="1.0" encoding="UTF-8"?>
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ns1="http://statistik.uni-c.dk/instreg/">
    <SOAP-ENV:Body>
        <ns1:HelloWorldCredentials/>
    </SOAP-ENV:Body>
</SOAP-ENV:Envelope>

为什么请求中完全没有我的参数？

根据方法的WSDL，您需要在soap

信封的
头中而不是
正文中发送凭据

所以这应该是可行的：

<?php
$client = new SoapClient("https://statistik.uni-c.dk/instregws/DataServiceXML.asmx?wsdl", array('trace' => 1));

$credentials = array(
    'Username' => 'Obviously',
    'Password' => 'NotPublic'
);    
$header = new SoapHeader('http://statistik.uni-c.dk/instreg/', 'Credentials', $credentials);
$client->__setSoapHeaders($header);

$response = $client->HelloWorldCredentials();

echo("\n*** REQUEST ***\n");
echo( $client->__getLastRequest() );

echo("\n*** RESPONSE ***\n");
var_dump( $response );

1]；
$credentials=数组(
“用户名”=>“显然”，
'密码'=>'不公开'
);    
$header=新的SoapHeader（'http://statistik.uni-c.dk/instreg/“，”凭证“，$Credentials）；
$client->uu setSoapHeaders（$header）；
$response=$client->HelloWorldCredentials（）；
回音（“\n***请求***\n”）；
echo（$client->u getLastRequest（））；
回音（“\n***响应***\n”）；
var_dump（$response）；
Gah。非常感谢！：-）他们为什么要把它放在标题里。。。？
*** RESPONSE ***
object(stdClass)#3 (1) {
  ["HelloWorldCredentialsResult"]=>
  string(19) "Missing credentials"
}

<?php
$client = new SoapClient("https://statistik.uni-c.dk/instregws/DataServiceXML.asmx?wsdl", array('trace' => 1));

$credentials = array(
    'Username' => 'Obviously',
    'Password' => 'NotPublic'
);    
$header = new SoapHeader('http://statistik.uni-c.dk/instreg/', 'Credentials', $credentials);
$client->__setSoapHeaders($header);

$response = $client->HelloWorldCredentials();

echo("\n*** REQUEST ***\n");
echo( $client->__getLastRequest() );

echo("\n*** RESPONSE ***\n");
var_dump( $response );
