下面是个控制台的样例

Toolkit3.0 终于给出VC6的样例了，1.0只能看到VB和ASP的

#include <stdio.h>

#import “msxml4.dll”

using namespace MSXML2;

#import “C:/Program Files/Common Files/MSSoap/Binaries/mssoap30.dll” /

exclude(“IStream”, “IErrorInfo”, “ISequentialStream”, “_LARGE_INTEGER”, /

“_ULARGE_INTEGER”, “tagSTATSTG”, “_FILETIME”)

using namespace MSSOAPLib30;  //你机器得安装SOAP Toolkit3.0 ，1.0时，用using namespace时报错

void Add()

{


ISoapSerializerPtr Serializer;

ISoapReaderPtr Reader;

ISoapConnectorPtr Connector;

// Connect to the service.

Connector.CreateInstance(__uuidof(HttpConnector30));  //HttpConnector30 失败，无法这样创建Connector，CXX0017 Error :Symbol “HttpConnector30“ not found（摇头、叹气！）

Connector->Property[“EndPointURL”] = “http://MyServer/Soap3DocSamples/DocSample1/Server/DocSample1.wsdl”;  //这个当然得改成您自己的拉

Connector->Connect();

// Begin the message.

//Connector->Property[“SoapAction”] = “uri:AddNumbers”;

Connector->Property[“SoapAction”] = “http://tempuri.org/DocSample1/action/Sample1.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(“”,””,””);

Serializer->StartBody(“”);

Serializer->StartElement(“AddNumbers”,”http://tempuri.org/DocSample1/message/”,””,””);  //这是本地的Web Services,实际中要指定命名空间

Serializer->StartElement(“NumberOne”,””,””,””);

Serializer->WriteString(“5”);

Serializer->EndElement();

Serializer->StartElement(“NumberTwo”,””,””,””);

Serializer->WriteString(“10”);

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();

CoUninitialize();

return 0;

}

更改 EndPointURL 属性的值. 在URL里指定你的服务器名.

OK

总结一下必要的关键步骤

1.导入类型库

2.需要创建一个SoapConnector

3.下一步创建SoapSerializer

4.下一步把消息附加到SoapConnector的输入流

5.下一步读取结果.要读取服务器的回复,客户端应用需要使用SoapReader,

6.SoapReader被连接到SoapConnector输出流

7.用IXMLDOMElement对象可以从SoapReader里读到服务器的回复
