PHP SOAP客戶端致命錯誤

Question

我在工作的機器上運行PHP SOAP客戶端時遇到麻煩。 這是我的PHP SOAP客戶端：

    <?php

$params=array("SendMessageRequest" => 
    array( "GsbEnvelope" =>  
        array( "MessageHeader" => 
            array("SenderId" => "000000001",
                "ServiceId" => "000000002",
                "MessageId" => "833362f-063f-11e2-892e-0802200c9a62",
                "SenderTimeStamp" => "2013-12-03T14:39"),
                "Content" => array("MimeType" =>"application/xml","Data" =>"Nesto"))));

$client = new SoapClient("GSBService.wsdl", array(
                            "trace"=>1,
                            "exceptions"=>0,
                            "cache_wsdl" => 0));

print_r( $client->sendMessage($params));

echo "<p>Request :".htmlspecialchars($client->__getLastRequest()) ."</p>";
echo "<p>Response:".htmlspecialchars($client->__getLastResponse())."</p>";
echo "<p>Debug:".soapDebug($client)."</p>";
  ?>

這是WSDL文件：

</wsdl:definitions>

輸出為：

我可以通過Web瀏覽器輕松訪問xmldsig-core-schema.xsd文件，我的管理員告訴我端口80和443沒有被阻止。

我通過在php.ini中啟用功能“ libxml_disable_entity_loader”解決了此問題

注意：您還必須在應用程序的啟動腳本中的某處調用libxml_disable_entity_loader（false），以啟用外部XML實體的加載。
