#include <stdio.h>  
#include <afxinet.h>  
int main(int argc, char* argv[])  
{  
    CInternetSession session("HttpClient");  
    char * url = " http://www.sohu.com "; //随便抓一个
    CHttpFile* pfile = (CHttpFile *)session.OpenURL(url);  
    DWORD dwStatusCode;  
    pfile -> QueryInfoStatusCode(dwStatusCode);  
    if(dwStatusCode == HTTP_STATUS_OK)  
    {  
        CString content;  
        CString data;  
        while (pfile -> ReadString(data))  
        {  
            content  += data + "/r/n";  
        }  
        content.TrimRight();  
        printf(" %s/n " ,(LPCTSTR)content);  
    }   
    pfile -> Close();  
    delete pfile;
