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.

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。
