SOAP，碰到VersionMismatch,求解决

SOAP，遇到VersionMismatch,求解决
先贴代码出来

<?php
header("Content-Type: text/html;charset=utf-8");  
try{  
    $client = new SOAPClient(null,
        array('location' =>"http://v2.shanxitele.com/service/OutWebService?wsdl",'uri' => "http://127.0.0.1/"));
   
    $servicename = 'OAuth';
    $servId = 'xxx';
    $secretKey = 'xxx';
    $xmlInfo = '<?xml version="1.0" encoding="UTF-8"?><BaseInfo><servId>fc4fa30c444400b701446c540230244e</servId><platform>yixin</platform><type>base</type><redirect_uri>lcoalhost/index.php</redirect_uri></BaseInfo>';
 
    $result = $client->callService($servicename, $servId, $secretKey, $xmlInfo);
    var_dump($result);
}catch(SOAPFault $e){  
    echo "Error: ",$e->faultcode,", string: ",$e->faultstring;
}  

?>

记过错误代码Error: VersionMismatch, string: Wrong Version

求解决。
------解决方案--------------------

提供的方法
Array
(
    [0] => callServiceResponse callService(callService $parameters)
)
相关的数据结构
Array
(
    [0] => struct callService {
 string in0;
 string in1;
 string in2;
 string in3;
}
    [1] => struct callServiceResponse {
 string out;
}
)

你总得按规矩来吧？
------解决方案--------------------
按照我这个来

try {
			$xml='xml数据';
			//地址
			$soap = new SoapClient ( "http://mp.vservice.com.cn/service/OutWebService?WSDL" );
			//请求参数 根据你的参数调整
			$param = array ('userName' => '*****', 'pwd' => '****', 'businessType' => 'SaleHouses', 'xmlContent' => $xml );
			//调用服务器端的方法 根据你的方法调整 我这里Import是方法名称
			$result = $soap->__soapCall ( 'Import', array ('parameters' => $param ) );
			print_r ( $result );
		} catch ( SoapFault $e ) {
			echo $e->getMessage ();
		} catch ( Exception $E ) {
			echo $E->getMessage ();
		}
