MFC获取远程网页HTML代码产生的乱码问题

 

看代码吧: 

CString CCommon::GetHtml(CString server,CString path,CString postData)
...{
    static CInternetSession sess;
    CHttpFile* pFile; 
    CHttpConnection* pConn;
    
    pConn=sess.GetHttpConnection(server,(INTERNET_PORT)2930);
    pFile=pConn->OpenRequest(CHttpConnection::HTTP_VERB_POST,path);
    //pFile->SendRequest(NULL,0,postData,postData.GetLength());
    if(!postData==NULL)
    ...{
        CString strHeaders=_T(" Content-Type:application/x-www-form-urlencoded;charset=gb2312");   //   请求头 
        pFile->SendRequest(strHeaders,strHeaders.GetLength(),(LPVOID)(LPCTSTR)postData,postData.GetLength());
    }

    CString html,strLine = _T( " "); 
    DWORD dwStatus; 
    DWORD dwBuffLen =sizeof(dwStatus); 
    
    pFile->QueryInfoStatusCode(dwStatus);
    //BOOL bSuccess=pFile->QueryInfo(HTTP_QUERY_STATUS_CODE|HTTP_QUERY_FLAG_NUMBER,&dwStatus,&dwBuffLen); 
    if(dwStatus==HTTP_STATUS_OK)
    ...{
        
        while(pFile->ReadString(strLine))         //   读取提交数据后的返回结果 
        ...{ 
            html=html+strLine+char(13)+char(10); 
        }
    } 
    else
    ...{ 
        html="0";
    }
    pFile->Close(); 
    delete pFile;   

    return html;
}

调用:

CString str=CCommon::GetHtml("127.0.0.1","WebSite3/Default.aspx","a=中国&b=aa&c=cc");
 MessageBox(str);

发现"中国"变成了乱码,

解决的方法如下:

WebSite3/Default.aspx是用c#做的,我的方法是在服务器端输出时进行编译转换

Response.Charset = "gb2312";
        Response.ContentEncoding = System.Text.Encoding.GetEncoding("gb2312");
        Response.Write(Request.HttpMethod+" ");
        NameValueCollection vc = Request.Form;
        foreach(string key in vc.Keys)
        ...{
            Response.Write(key + ":" + vc[key] + " ");
        }
        Response.End();

再次运行,一切都OK了...
