java - 从 PHP 调用 Web 服务

Question

我一直在尝试从下到上的方法调用在java中创建的Web服务，并想通过我的PHP文件调用它，但它总是给我一个错误。

我尝试过的代码:

$client = new SoapClient("http://localhost:8080/Indexer/services/IndexerService?wsdl");
$params = array(
      'anId' => 3,
      'action' => 'OMNOMNOMNOM',
      'parameters' => array(
                  'Param' => array(
                          array('Name' => 'in0', 'Value' => 'Skinnarlyngen startar Välkommen')
      )
));
$result = $client->__soapCall("getIds",$params);

print_r($result);

我尝试过的第二段代码:

$wsdl = 'http://localhost:8080/Indexer/services/IndexerService?wsdl';   
  $client = new SoapClient($wsdl );

  print($client->getIds("ibm"));

我的网络服务在使用 java 客户端尝试时给出了完美的结果:

<wsdlsoap:address location="http://localhost:8080/Indexer/services/IndexerService"/>
</wsdl:port>
</wsdl:service>
</wsdl:definitions>

在每种情况下，它都会给我以下错误:

Fatal error: SOAP-ERROR: Parsing WSDL: Couldn't load from 'http://localhost:8080/Indexer/services/IndexerService?wsdl' : failed to load external entity 

任何人都可以帮我解决如何在 php 代码中调用 java 编写的 Web 服务吗？

我想提一下，我正在使用 php 5，并且 wamp 已经在我的 php 中启用了soap 扩展。

您可以使用的一个不错的工具是 wsdl2php-interpreter ，它将为您创建四个类等。
