Ilias SOAP 构造函数登录时出错

Question

我正在测试 Ilias Soap 接口。而且我的登录功能有问题。

<?php
include_once ("./nusoap/nusoap.php");
$client = new nusoap_client("https://localhost/ilias/webservice/soap/server.php?wsdl");
$client->soap_defencoding = 'UTF-8'; //that is a not working solution from stackoverflow
if ($err = $client->getError()) 
{
echo '<h2>Constructor error</h2><pre>' . $err . '</pre>';
}
$valid = $client->call('login',
array('client' => "ILIAS",
'password' => "pw",
'username' => "root"));
if ($err = $client->getError()) 
{
echo '<h2>Constructor error</h2><pre>' . $err . '</pre>';
}
print_r($client);
?>

我收到此错误：

构造函数错误 肥皂错误：解析 WSDL：无法从"http://localhost/ilias/webservice/soap/nusoapserver.php?wsdl"加载：文档末尾有额外内容

这是打印对象：

有什么想法吗？

Answer 1

加载 https://localhost/ilias/webservice/soap/server.php?wsdl 并将结果保存在某个文件中。然后使用一些XML验证器(例如 https://www.xmlvalidation.com/(并检查文档是否有效。

如果生成 WSDL 的 PHP 代码中的某些内容将输出写入文件，例如 PHP 错误消息，则通常会发生您描述的问题。这可能已经在文件中肉眼可见。

然后采取适当的操作来清理输出并获取正确的 WSDL。

Answer 2

在这里您可以尝试下面的代码，在带有 nusoap-0.9.5 库的 ILIAS 5.3.8 上为我工作，iirc 项目中的那个也对我不起作用。

require_once("./nusoap-0.9.5/lib/nusoap.php");
$wsdlUrl = "http://yourilias/webservice/soap/server.php?wsdl";
$soapClient = new nusoap_client($wsdlUrl, true);
$login["client"] = 'client1';
$login["username"]  = "root";
$login["password"] = "rootPass";
$sessionId = $soapClient->call("login", $login); // call other soap requests using the sessiondId/sid
echo var_dump(lookupUser("John Doe"));
function lookupUser($login)
{
global $soapClient, $sessionId;
$user = $soapClient->call("lookupUser", array($sessionId, $login));
if ($user != 0) {
return $user;
}
return 0;
}
