c#创建webService, vc++ 调用

 1、安装 SoapToolkit

2、CString bBackQuestion;
  bBackQuestion =(const char*)Reader->Body->xml; //可以查看错误原因，

3、不能识别http头，导致返回Soap::Client问题，需要c#创建WebService时，添加申明

[SoapDocumentService(RoutingStyle = SoapServiceRoutingStyle.RequestElement)]

 

代码如下：(代码未经整理，不能直接运行。。。vc++用户可以稍微修改下即可)

c#代码不需要修改,直接创建 ASP WEB复制即可

c# 

using System;
using System.Web;
using System.Web.Services;
using System.Web.Services.Protocols;
using System.Configuration;
using System.Data.SqlClient;
using System.Collections;
using System.Runtime.InteropServices;

[WebService(Namespace = "http://mywebservice/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
[SoapDocumentService(RoutingStyle = SoapServiceRoutingStyle.RequestElement)]
//[System.Web.Services.Protocols.SoapRpcService]

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]
    //返回提取新号码的一些信息
    public string test()
    {        

        return "succeful~";

    }

}

 

vc++: .h

#import "msxml4.dll"
#import "mssoap30.dll" \
exclude("IStream", "IErrorInfo", "ISequentialStream", "_LARGE_INTEGER", \
"_ULARGE_INTEGER", "tagSTATSTG", "_FILETIME")
