从PHP调用Web服务

Question

我一直试图从底层到顶层的方法调用java创建的web服务，并希望通过我的PHP文件调用它，但它总是给我一个错误。

代码我尝试过：

$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web服务在使用java客户端尝试时提供了完美的结果：

</wsdl:service>
</wsdl:definitions>

在每种情况下，它都给了我以下错误：

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

任何人都可以帮助我，我怎么能在PHP代码中调用java编写的web服务。

我想提一下，我在php中使用php 5和wamp已经启用了soap扩展。

Answer 1

你可以使用的一个很好的工具是wsdl2php-interpreter ，它会创建四个类等等。

Answer 2

使用以下代码

 $Url = "http://localhost:8080/Indexer/services/IndexerService?wsdl";
    $params = array ("param1" =>"value","parm2"=>"value");

    $httpQuery = http_build_query ($params);
    $contextData = array (
                    "method" => "POST",
            "header" => "Connection: close\r\n".
                    "Content-Length: ".strlen($httpQuery)."\r\n",
                    "content"=> $httpQuery );               

    $context = stream_context_create (array ( "http" => $contextData )); 
    $result =  file_get_contents ($Url, false, $context);
