其实没什么难度，只是要调发送的xml格式，建议使用SoapUI调好，再粘到项目中
就是使用 msxml因为是mfc的东西，要在项目中设置在共享DLL中使用MFC
还有要在调用的服务后面加?wsdl解释成xml格式
代码
webservice
复制代码 代码如下:
using System;
using System.Data;
using System.Web;
using System.Collections;
using System.Web.Services;
using System.Web.Services.Protocols;
using System.ComponentModel;
namespace WebService
{
/// <summary>
/// Service1 的摘要说明
/// </summary>
[WebService(Namespace = "http://www.jb51.net/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
[ToolboxItem(false)]
public class Service1 : System.Web.Services.WebService
{
[WebMethod]
public string HelloWorld()
{
return "Hello World";
}
[WebMethod]
public string SayHello(string name)
{
return "Hello "+name;
}
}
}
头文件
[code]
#pragma once
#include "stdafx.h"
#include "Atlbase.h"
//#import "msxml.dll"
#import "msxml4.dll"
using namespace MSXML2;
#include <string>
#include <iostream>
using namespace std;
调用代码
复制代码 代码如下:
#include "Main.h"
int main(int argc, char* argv[])
{
printf("Test of XMLHTTP by masterz!n");
CoInitialize(NULL);
try
{
IXMLHTTPRequestPtr xmlrequest;//定义http请求对象
xmlrequest.CreateInstance(__uuidof(XMLHTTP));//创建实列
CComVariant vFalse(FALSE);
CComVariant vNull(NULL);
xmlrequest->open("POST",bstr_t("http://192.168.71.172/Service1.asmx?wsdl"),vFalse,vNull,vNull);//打开WEBServeice方法:加?wsdl
xmlrequest->setRequestHeader(_bstr_t(_T("Content-Type")), _bstr_t(_T("text/xml")));
string sb;
sb.append("<?xml version='1.0' encoding='utf-8'?>");
sb.append("<soapenv:Envelope xmlns:soapenv='http://www.jb51.net/soap/envelope/' xmlns:tem='http://www.jb51.net/'>");
sb.append("<soapenv:Header/>");
sb.append("<soapenv:Body>");
//sb.append("<tem:HelloWorld/>");//调用HelloWorld函数
sb.append("<tem:SayHello>");
sb.append("<tem:name>colin</tem:name>");//调用SayHello函数，参数名是name，值为colin
sb.append("</tem:SayHello>");
sb.append("</soapenv:Body>");
sb.append("</soapenv:Envelope>");
xmlrequest->send(_variant_t(sb.c_str()));//发道数据
BSTR bstrbody;
xmlrequest->get_responseText(&bstrbody);//得到返回数据
_bstr_t bstrtbody(bstrbody);
printf("%sn",(LPCTSTR)bstrtbody);
MSXML2::IXMLDOMDocument2Ptr m_xmldoc;
m_xmldoc.CreateInstance(__uuidof(MSXML2::DOMDocument));
m_xmldoc->loadXML(bstrbody);
MSXML2::IXMLDOMNodePtr node = m_xmldoc->documentElement->firstChild;
LPCTSTR str = (LPCTSTR)node->nodeName;
string str2=(string)m_xmldoc->documentElement->text;
cout<<str2<<endl;
}
catch (_com_error &e)
{
printf("Description = '%s'n", (char*) e.Description());
}
CoUninitialize();
printf("program endn");
return 0;
}
