我已经将WSDL转换为PHP脚本，但有些东西不起作用，我正在尝试连接http://www.regcheck.org.uk/api/reg.asmx?wsdl，但是得到这个错误
Array ( [RegCheckServiceCheck::Check] => SoapFault Object ( [message:protected] => System.Web.Services.Protocols.SoapException: Server was unable to process request. ---> System.NullReferenceException: Object reference not set to an instance of an object. at webtropy.CarReg.Check(String RegistrationNumber, String username) in c:'inetpub'wwwroot'regcheck.org.uk'api'reg.asmx:line 26 --- End of inner exception stack trace --- [string:Exception:private] => [code:protected] => 0 [file:protected] => C:'xampp'htdocs'Check'RegCheckServiceCheck.php [line:protected] => 32 [trace:Exception:private] => Array ( [0] => Array ( [file] => C:'xampp'htdocs'Check'RegCheckServiceCheck.php [line] => 32 [function] => __call [class] => SoapClient [type] => -> [args] => Array ( [0] => Check [1] => Array ( [0] => RegCheckStructCheck Object ( [RegistrationNumber] => [username] => [result:RegCheckWsdlClass:private] => [lastError:RegCheckWsdlClass:private] => Array ( ) [internArrayToIterate:RegCheckWsdlClass:private] => [internArrayToIterateIsArray:RegCheckWsdlClass:private] => [internArrayToIterateOffset:RegCheckWsdlClass:private] => ) ) ) ) [1] => Array ( [file] => C:'xampp'htdocs'Check'RegCheckServiceCheck.php [line] => 32 [function] => Check [class] => SoapClient [type] => -> [args] => Array ( [0] => RegCheckStructCheck Object ( [RegistrationNumber] => [username] => [result:RegCheckWsdlClass:private] => [lastError:RegCheckWsdlClass:private] => Array ( ) [internArrayToIterate:RegCheckWsdlClass:private] => [internArrayToIterateIsArray:RegCheckWsdlClass:private] => [internArrayToIterateOffset:RegCheckWsdlClass:private] => ) ) ) [2] => Array ( [file] => C:'xampp'htdocs'sample-regcheck.php [line] => 46 [function] => Check [class] => RegCheckServiceCheck [type] => -> [args] => Array ( [0] => RegCheckStructCheck Object ( [RegistrationNumber] => [username] => [result:RegCheckWsdlClass:private] => [lastError:RegCheckWsdlClass:private] => Array ( ) [internArrayToIterate:RegCheckWsdlClass:private] => [internArrayToIterateIsArray:RegCheckWsdlClass:private] => [internArrayToIterateOffset:RegCheckWsdlClass:private] => ) ) ) ) [previous:Exception:private] => [faultstring] => System.Web.Services.Protocols.SoapException: Server was unable to process request. ---> System.NullReferenceException: Object reference not set to an instance of an object. at webtropy.CarReg.Check(String RegistrationNumber, String username) in c:'inetpub'wwwroot'regcheck.org.uk'api'reg.asmx:line 26 --- End of inner exception stack trace --- [faultcode] => soap:Server [detail] => ) )我确信配置文件中缺少了什么，我想有人知道吗？
可以通过HTTP GET请求调用该web服务，如下所示；
<?php
$username = 'Your username here';
$regNumber = 'SK08KPT';
$xmlData = file_get_contents("https://www.regcheck.org.uk/api/reg.asmx/Check?RegistrationNumber=" . $regNumber ."&username=" . $username);
$xml=simplexml_load_string($xmlData);
$strJson = $xml->vehicleJson;
$json = json_decode($strJson);
print_r($json->Description);
?>
没有SOAP调用那么优雅，但更简单。
