vc++ 访问php webService

starxzj

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.iyunv.com/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", \
    "_ULARGE_INTEGER", "tagSTATSTG", "_FILETIME")
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。
