vc++ 通路php webService

之前做了一個VC++通路c#制作的WebService，沒有問題，接着我又做了一個VC++通路php制作的WebService ,

結果老是出現Client錯誤。這個php WebService是用ZendStudio制作的，後來采用NUSoap做php的WebService就沒問題。

以下為整個過程：

NUSoap WebService自作.

1.php WebService 檔案： nusoap_server3.php，以下為代碼：

<a></a>

&lt;?php

require_once("lib/nusoap.php");

function AddNumbers($NumberOne,$NumberTwo)

{

    return $NumberOne+$NumberTwo;

}

$soap = new soap_server;

 // 初始化對 WSDL 的支援

$soap-&gt;configureWSDL('AddNumbers');

// 注冊服務

$soap-&gt;register('AddNumbers',

array("NumberOne"=&gt;"xsd:int","NumberTwo"=&gt;"xsd:int"),

array("retrun"=&gt;"xsd:int")           

);

$HTTP_RAW_POST_DATA = isset($HTTP_RAW_POST_DATA) ? $HTTP_RAW_POST_DATA : '';

$soap-&gt;service($HTTP_RAW_POST_DATA);

?&gt; 

2.VC用戶端制作，以下是控制台應用程式制作。

#include "stdafx.h"

#include &lt;stdio.h&gt;

#include &lt;stdlib.h&gt;

//先導入msxml4.dll，再導入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-&gt;Property["EndPointURL"] = "http://localhost/test/nusoap/nusoap_server3.php";  

    Connector-&gt;Connect();

    //Connector-&gt;Property["SoapAction"] = "http://Fantasy/WebServiceDemo/AddNumbers";

    Connector-&gt;Property["SoapAction"] = "http://localhost/test/nusoap/nusoap_server3.php/AddNumbers";

    Connector-&gt;BeginMessage();      

    // Create the SoapSerializer object.

    Serializer.CreateInstance(__uuidof(SoapSerializer30));

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

    Serializer-&gt;Init(_variant_t((IUnknown*)Connector-&gt;InputStream));

    // Build the SOAP Message.

    Serializer-&gt;StartEnvelope("","","");

    //這裡可以添加SoapHeader驗證代碼：

    /*

    Serializer-&gt;StartHeader("");

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

    Serializer-&gt;StartElement("UserName","","","");//填充參數2則出錯。

    Serializer-&gt;WriteString(_bstr_t(userName));

    */

    Serializer-&gt;StartBody("");   

    //Serializer-&gt;StartElement("AddNumbers"," http://localhost/test/soap/Server.php/","","");

    //Serializer-&gt;StartElement("AddNumbers","http://Fantasy/WebServiceDemo/","","");

    Serializer-&gt;StartElement("AddNumbers","","","");

    //(第三個參數可有可無，若加上第二個參數出錯！？)

    Serializer-&gt;StartElement("NumberOne","","","");// NumberOne=

    Serializer-&gt;WriteString((_bstr_t)str1);

    Serializer-&gt;EndElement();      

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

    Serializer-&gt;WriteString((_bstr_t)str2);

    Serializer-&gt;EndElement();

    Serializer-&gt;EndElement();  

    //

    Serializer-&gt;EndBody();

    Serializer-&gt;EndEnvelope();

    // Send the message to the XML Web service.   

    Connector-&gt;EndMessage();   

    // Read the response. 

    Reader.CreateInstance(__uuidof(SoapReader30));    

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

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

    // Display the result.

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

int main()

{   

    CoInitialize(NULL);   

    Add(1211,21114);  

    CoUninitialize();

    return 0;

注意：此方法隻對NUSOAP制作的WebService有效，對zendStudio制作的WebService無效。
