php - 只有响应的第一个元素可见 - php

Question

我正在从事一个项目，我需要从网络服务中获取一些数据，并需要使用 PHP 在屏幕上显示这些数据。

当我在 soapUI 中执行网络服务时，我得到了这个响应:

<soapenv:Envelope xmlns:ns="http://schemas.test.nl/are/planning/business/1.0" xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
   <soapenv:Header>
      <header xmlns="http://schemas.cordys.com/General/1.0/">

      </header>
   </soapenv:Header>
   <soapenv:Body>
      <tonenbeschikbaarheidportaalresponse xmlns="http://schemas.test.nl/are/planning/business/1.0">

               </day>
            </beschikbaarheidslijst>
         </tonenbeschikbaarheidportaalresult>
      </tonenbeschikbaarheidportaalresponse>
   </soapenv:Body>
</soapenv:Envelope>

我需要的是，我可以遍历每个 beschikbaarheidslijst(荷兰语的可用性列表)。

问题是我的代码中的响应几乎是空的(或不可见的): 我检查了其他系统中的 Web 服务是否给出了带有值的响应，并且确实如此。

$beschikbaarheid = $response[1];
var_dump($beschikbaarheid);

输出: 对象(stdClass)#51(1){ [“tonenbeschikbaarheidportaalresult”]=> 对象(stdClass)#52(0){ }

对于 print_r，其他对象也是不可见的:

$beschikbaarheid = $response[1];
print_r($beschikbaarheid);

输出: 标准类对象 ( [tonenbeschikbaarheidportaalresult] => stdClass 对象 ( ) )

我想遍历 $beschikbaarheid 响应，但代码没有到达那里。 $item 为 NULL。

foreach($beschikbaarheid->tonenbeschikbaarheidportaalresult->children('http://schemas.test.nl/are/planning/business/1.0')->beschikbaarheidslijst as $item)
{
  echo '<pre>';
  var_dump(get_object_vars($item));  // gives NULL
  echo '</pre>';
  $data[] = get_object_vars($item);
}

当我删除 children(' http://schemas.test.nl/are/planning/business/1.0 ')-> 时，我会收到通知，因此 namespace 必须正确:

Notice: Undefined property: stdClass::$beschikbaarheidslijst in D:\xampp\htdocs\prive\CCP\includes\inc_formulieren.php on line 187

你能告诉我如何遍历 beschikbaarheidslijst 元素吗？ 我必须对属性 starttime="06:00:00.0"做些什么吗？

<beschikbaarheidslijst starttime="06:00:00.0">

我从 web 服务获得 soap 响应。

$response = call_service( $serviceOperation, $request, $entiteit, $backend );

echo '<pre> response from webservice ';
var_dump($response);
echo '</pre>';

response from webservice array(2) {
  [0]=>
  int(0)
  [1]=>
  object(stdClass)#51 (1) {
    ["tonenbeschikbaarheidportaalresult"]=>
    object(stdClass)#52 (0) {
    }
  }
}

使用 SoapClient 和扩展调用服务:

class SoapClientNG extends \SoapClient
{

    public function __doRequest($req, $location, $action, $version = SOAP_1_1)
    {

        $xml = explode("\r\n", parent::__doRequest($req, $location, $action, $version));
        $response = preg_replace( '/^(\x00\x00\xFE\xFF|\xFF\xFE\x00\x00|\xFE\xFF|\xFF\xFE|\xEF\xBB\xBF)/', "", $xml[5] );
        return $response;
    }
}   


function call_service( $serviceOperation, $request, $entiteit, $backend )
{
    $error = 0; 

    $soapClient = getSoapClient($entiteit, $backend);

    try { 
            $response = $soapClient->__call($serviceOperation, array($request)); 

        }    
    catch (SoapFault $fault) { 
        $error = 1; 
        $response = $fault->faultcode."-".$fault->faultstring;
    } 

return array($error, $response);

}

解决方案结合文森特的回答:

我看到我的响应是一个对象，但是当我打印 __getLastResponse() 时，我得到了 XML。 http://php.net/manual/en/soapclient.getlastresponse.php

$response = $soapClient->__getLastResponse();

当我在 Vincent 的回答中使用它时，我在屏幕上看到了值:

$xml = simplexml_load_string($response);

  $xml->registerXPathNamespace('list', 'http://schemas.test.nl/are/planning/business/1.0');

foreach ($xml->xpath('//list:beschikbaarheidslijst') as $list_object) 
{
  print_r($list_object);
}

Answer 1

您的代码中缺少命名空间声明，因此它不起作用，应该首先声明此命名空间 http://schemas.test.nl/are/planning/business/1.0 并且然后你可以加载 XML 字符串，执行此操作..

$xml_str = "YOUR SOAP RESPONSE HERE";

$xml = simplexml_load_string($xml_str);

$xml->registerXPathNamespace('list', 'http://schemas.test.nl/are/planning/business/1.0');
foreach ($xml->xpath('//list:beschikbaarheidslijst') as $list_object)
{
    print_r($list_object);
}

这应该可以解决问题。 fiddle :https://eval.in/534908
