分享用PHP访问WebService，如何看懂WSDL中的数据格式呢？
<wsdl:definitions targetNamespace="http://ui.server.pointquery.vas.soap.interfaces.lcsmp.linkage.com" xmlns:apachesoap="http://xml.apache.org/xml-soap" xmlns:impl="http://ui.server.pointquery.vas.soap.interfaces.lcsmp.linkage.com" xmlns:intf="http://ui.server.pointquery.vas.soap.interfaces.lcsmp.linkage.com" xmlns:tns1="http://req.ui.server.pointquery.vas.soap.interfaces.lcsmp.linkage.com" xmlns:tns2="http://rsp.ui.server.pointquery.vas.soap.interfaces.lcsmp.linkage.com" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" xmlns:wsdlsoap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:xsd="http://www.w3.org/2001/XMLSchema">

</wsdl:definitions>以上是我要去访问的WebService的WSDL文档。我要用PHP语言去访问queryPoint这个功能接口。
于是我编写的代码核心部分如下：
@require_once(_SysDir_ . '/inc/lib/soap/nusoap.php');
$pclient = new soapclient('http://192.168.11.4:12000/payApi/do/purchase/PointQueryService.wsdl');
$pclient->soap_defencoding = 'utf-8';
$pclient->xml_encoding = 'utf-8';
$now_time = time();
$randStr = getRandomString(18);
class PointQueryReq
{
public $SPID;
public $transactionID;
public $userID;
public $userToken;
}
class requestZ
{
public $req;
}
$InputZ=new PointQueryReq();
$InputZ->SPID=$jsdx_api_spid;
$InputZ->userID=$_POST['VAccount'];
$InputZ->transactionID=''.$jsdx_api_spid.date('YmdHis', $now_time).$randStr;
$InputZ->userToken=$_POST['userToken'];
$requstZ=new requestZ();
$requstZ->req=$InputZ;
$param = new SoapParam($requstZ, 'tns1:PointQueryReq');
$try_times = 0 ;
$queryResutl='';
while (true)
{
$queryResutl = @$pclient->__soapCall('queryPoint',array('queryPointRequest'=>$param));
if ($queryResutl != "")
{
break;
}
if ($try_times > 3)
{
break;
}
$try_times++;
}结果在网页上提示如下错误：
Fatal error: Uncaught SoapFault exception: [Client] looks like we got no XML document in D:\WWW\payApi\do\purchase\jsdx.inc.php:88 Stack trace。
这是我第一次去学着看懂WSDL，并且尝试用PHP去访问，数据格式是我参考了很多例子写的，
不知道是否正确，麻烦高人指点。可以留QQ交流，大家交个朋友。

可用的方法
print_r($pclient->__getFunctions());
可用的数据结构
print_r($pclient->__getTypes());
对于你的 WSDL 是
Array
(
[0] => queryPointResponse queryPoint(queryPoint $parameters)
)
Array
(
[0] => struct queryPoint {
PointQueryReq req;
}
[1] => struct queryPointResponse {
PointQueryRsp queryPointReturn;
}
[2] => struct PointQueryReq {
string SPID;
string transactionID;
string userID;
string userToken;
}
[3] => struct PointQueryRsp {
string description;
string point;
int pointRate;
string result;
string transactionID;
string userID;
}
)
