1. 首先要安装SoapToolkit3.0安装包并安装(我的安装目录为:C:\Program Files\Common Files)
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)
3。main.cpp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;
}
3>通过vs2010发布服务, 添加webservices,文件名Service.asmx,不能通过wcf发布,否则上面的代码回报错。
Service.asmx文件源码
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;
}
}
