用M$的SoapToolkit+VC6进行Web Service Client的开发

好郁闷哦，用Java调用Web Service习惯了再回到VC上，哎，突然发现自己不适应了！！

真是的，是不是自己真的老了？？

让我们开始吧。

首先引入必须得库

#import "msxml3.dll"

#import "C:/Program Files/Common Files/MSSoap/Binaries/mssoap1.dll" /
exclude("IStream","ISequentialStream","_LARGE_INTEGER",/
"_ULARGE_INTEGER","tagSTATSTG","_FILETIME")

再使用相应的命名空间

using namespace MSXML2;

using namespace MSSOAPLib;

接下来就可以进行操作了

代码片段如下：

ISoapSerializerPtr Serializer;
ISoapReaderPtr Reader;
ISoapConnectorPtr Connector;
//实例化一个连接器
Connector.CreateInstance(__uuidof(HttpConnector));

Connector->Property["EndPointURL"]=http://135.233.131.67:8080/axis/services/TestService;
Connector->Connect();
Connector->Property["SoapAction"]="TestMethods";
Connector->BeginMessage();
Serializer.CreateInstance(__uuidof(SoapSerializer));
Serializer->Init(_variant_t((IUnknown*)Connector->InputStream));
Serializer->startEnvelope("","","");
Serializer->startBody("");
Serializer->startElement("getName","http://135.233.131.67:8080/axis/services/TestService?method=TestMethods","","m");
//传递第一个参数
Serializer->startElement("ParameterOne","","","");
Serializer->writeString("ValueOne");
Serializer->endElement();
//传递第二个参数
Serializer->startElement("ParameterTwo","","","");
Serializer->writeString("ValueTwo");
Serializer->endElement();

Serializer->endElement();
Serializer->endBody();
Serializer->endEnvelope();
Connector->EndMessage();
Reader.CreateInstance(__uuidof(SoapReader));

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

//取出结果，按照帮助文档文档的说法是：Returns the first child element of the first entry in the <Body>

//element of a Simple Object Access Protocol (SOAP) message.

printf("Return Message is : %s/n",(const char*)Reader->RPCResult->text);

OK，现在编译、运行，就可以看到结果了
