vc6控制台程序利用SoapToolkit3.0调用WebService

Posted 2020-07-10 hxb316

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：
