vc++ 访问php webService

   之前做了一个VC++访问c#制作的WebService，没有问题，接着我又做了一个VC++访问php制作的WebService ,
结果老是出现Client错误。这个php WebService是用ZendStudio制作的，后来采用NUSoap做php的WebService就没问题。
以下为整个过程：
NUSoap WebService自作.
参考网址： http://blog.csdn.net/raining_peidx/archive/2009/07/27/4384600.aspx
1.php WebService 文件： nusoap_server3.php，以下为代码：

<? php
require_once ( " lib/nusoap.php " );
function  AddNumbers( $NumberOne , $NumberTwo )
{
     return   $NumberOne + $NumberTwo ;
}
$soap   =   new  soap_server;
  //  初始化对 WSDL 的支持
$soap -> configureWSDL( ' AddNumbers ' );
//  注册服务
$soap -> register( ' AddNumbers ' ,
array ( " NumberOne " => " xsd:int " , " NumberTwo " => " xsd:int " ) ,
array ( " retrun " => " xsd:int " )           
);
$HTTP_RAW_POST_DATA   =   isset ( $HTTP_RAW_POST_DATA )  ?   $HTTP_RAW_POST_DATA   :   '' ;
$soap -> service( $HTTP_RAW_POST_DATA );
?>  

2.VC客户端制作，以下是控制台应用程序制作。

#include  " stdafx.h "
#include  < stdio.h >
#include  < stdlib.h >

// 先导入msxml4.dll，再导入mssoap30.dll
#import  " msxml4.dll "  
#import  " C:\Program Files\Common Files\MSSoap\Binaries\mssoap30.dll "  \
    exclude( " IStream " ,  " IErrorInfo " ,  " ISequentialStream " ,  " _LARGE_INTEGER " , \

using   namespace  MSXML2;
using   namespace  MSSOAPLib30; 

void  Add( int  No1, int  No2)

{
     // char *_itoa( int value, char *string, int radix );

     char  str1[ 10 ],str2[ 10 ];

    itoa(No1,str1, 10 ); itoa(No2,str2, 10 );

    ISoapSerializerPtr Serializer;

    ISoapReaderPtr Reader;

    ISoapConnectorPtr Connector;    

     //  Connect to the service.

    Connector.CreateInstance(__uuidof(HttpConnector30));   


    Connector -> Property[ " EndPointURL " ]  =   " http://localhost/test/nusoap/nusoap_server3.php " ;  
    Connector -> Connect();



    
     // Connector->Property["SoapAction"] = " http://Fantasy/WebServiceDemo/AddNumbers ";
    Connector -> Property[ " SoapAction " ]  =   " http://localhost/test/nusoap/nusoap_server3.php/AddNumbers " ;
    Connector -> BeginMessage();      

     //  Create the SoapSerializer object.

    Serializer.CreateInstance(__uuidof(SoapSerializer30));

     //  Connect the serializer object to the input stream of the connector object.

    Serializer -> Init(_variant_t((IUnknown * )Connector -> InputStream));

     //  Build the SOAP Message.

    Serializer -> StartEnvelope( "" , "" , "" );

     // 这里可以添加SoapHeader验证代码：

     /*

    Serializer->StartHeader("");

    Serializer->StartHeaderElement("MyHeader"," http://Fantasy/WebServiceDemo/ ",0,"","NONE","");   

    Serializer->StartElement("UserName","","","");//填充参数2则出错。

    Serializer->WriteString(_bstr_t(userName));

     */

    Serializer -> StartBody( "" );   

     // Serializer->StartElement("AddNumbers","  http://localhost/test/soap/Server.php/ ","","");
     // Serializer->StartElement("AddNumbers"," http://Fantasy/WebServiceDemo/ ","","");
    Serializer -> StartElement( " AddNumbers " , "" , "" , "" );

     // (第三个参数可有可无，若加上第二个参数出错！？)

    Serializer -> StartElement( " NumberOne " , "" , "" , "" ); //  NumberOne=

    Serializer -> WriteString((_bstr_t)str1);

    Serializer -> EndElement();      

    Serializer -> StartElement( " NumberTwo " , "" , "" , "" ); //  NumberOne= 

    Serializer -> WriteString((_bstr_t)str2);

    Serializer -> EndElement();

    Serializer -> EndElement();  

     //

    Serializer -> EndBody();

    Serializer -> EndEnvelope();

     //  Send the message to the XML Web service.   

    Connector -> EndMessage();   

     //  Read the response. 

    Reader.CreateInstance(__uuidof(SoapReader30));    

     //  Connect the reader to the output stream of the connector object.  

    Reader -> Load(_variant_t((IUnknown * )Connector -> OutputStream),  "" );    

     //  Display the result.

    printf( " Answer = %s\n " , ( const   char * )Reader -> RpcResult -> text);  

}

int  main()

{   

    CoInitialize(NULL);   

    Add( 1211 , 21114 );  

    CoUninitialize();

     return   0 ;

}

注意：此方法只对NUSOAP制作的WebService有效，对zendStudio制作的WebService无效。
