vc6控制台程序利用SoapToolkit3.0调用WebService

1.　首先要安装SoapToolkit3.0安装包并安装(我的安装目录为：D:\Program Files\MSSOAP\)

2. 新建vc控制台程序（空项目），项目名称：WinConsole6InvokeWebService，添加一个c++源文件(main.cpp)，将SOAP安装目录下的lib文件D:\Program Files\MSSOAP\Lib\mssoap30.lib复制到项目文件夹下。

3。添加源代码：

#include <stdio.h>
#include <iostream>
#include <vector>

#import "msxml4.dll"

using namespace std;
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;

void query(char* EndPointURL, char* Namespace, char* method, vector<string>& v)
{
ISoapSerializerPtr Serializer;
ISoapReaderPtr Reader;
ISoapConnectorPtr Connector;

// Connect to the service
Connector.CreateInstance(__uuidof(HttpConnector30));
Connector->Property["EndPointURL"] = EndPointURL;        // 接口位置
Connector->Connect();                                    // 和服务器连接

// Begin message
Connector->Property["SoapAction"] = _bstr_t(Namespace) + _bstr_t(method);
Connector->BeginMessage();

Serializer.CreateInstance(__uuidof(SoapSerializer30));

// 将serializer连接到connector的输入字符串
Serializer->Init(_variant_t((IUnknown*)Connector->InputStream));

// 创建SOAP消息
Serializer->StartEnvelope("soap", "", "");
Serializer->StartBody("body");
Serializer->StartElement(method, Namespace, "", ""); // 命名空间必须有

for(vector<string>::iterator it = v.begin(); it != v.end(); it++)
{
Serializer->StartElement("username", Namespace, "", "");
Serializer->WriteString(it->c_str());
Serializer->EndElement();
}

Serializer->EndElement();

Serializer->EndBody();
Serializer->EndEnvelope();

Connector->EndMessage();             // Send the message to the web service

// 读取响应
Reader.CreateInstance(__uuidof(SoapReader30));
Reader->Load(_variant_t((IUnknown*)Connector->OutputStream), "");

printf("Answer: %s\n", (const char*)Reader->RpcResult->text); // Reader->RpcResult->Gettext()等效
}

int main(int argc, char* argv[])
{
CoInitialize(NULL);
char* EndPointURL = "http://192.168.0.100/WebService1/Service.asmx";
char* Namespace = "http://tempuri.org/";

vector<string> v1, v2;

v2.push_back("JoeBlack");
query(EndPointURL, Namespace, "Hello", v2);

CoUninitialize();
getchar();

return 0;
}

　　

这样，程序就完成了，运行起来就可以得到WebService的服务了。

其中的WebService服务是用ASP.NET2005(C#)开发的，源码如下：

using System;
using System.Web;
using System.Web.Services;
using System.Web.Services.Protocols;

[WebService(Namespace = "http://tempuri.org/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
public class Service : System.Web.Services.WebService
{
public Service () {

//如果使用设计的组件，请取消注释以下行
//InitializeComponent();
}

[WebMethod(Description = "Let's say \"Hi\"")]
public string Hi()
{
return "Hello World, Happy New Year!";
}

[WebMethod(Description = "Hello JoeBlack")]
public string Hello(string username)
{
return username + ", Happy New Year!";
}

[WebMethod(Description = "求和的方法")]
public double addition(double i, double j)
{
return i + j;
}

[WebMethod(Description = "求差的方法")]
public double subtract(double i, double j)
{
return i - j;
}

[WebMethod(Description = "求积的方法")]
public double multiply(double i, double j)
{
return i * j;
}

[WebMethod(Description = "求商的方法")]
public double division(double i, double j)
{
if (j != 0)
return i / j;
else
return 0;
}
}

　　

调用的Hello方法，其调用方式如下：
