c++实现发送http请求通过get方式获取网页源代码

int _tmain(int argc, _TCHAR* argv[])
{
    urlopen(_T("http://www.weikejianghu.com"));
    return 0;
}
void urlopen(_TCHAR* url)
{
    HINTERNET hSession = InternetOpen(_T("UrlTest"), INTERNET_OPEN_TYPE_PRECONFIG, NULL, NULL, 0);
    if(hSession != NULL)
    {
        HINTERNET hHttp = InternetOpenUrl(hSession, url, NULL, 0, INTERNET_FLAG_DONT_CACHE, 0);
        if (hHttp != NULL)
        {
            wprintf_s(_T("%s\n"), url);
            BYTE Temp[MAXSIZE];
            ULONG Number = 1;
            while (Number > 0)
            {
                InternetReadFile(hHttp, Temp, MAXSIZE - 1, &Number);
                Temp[Number] = '\0';
                printf("%s", Temp);
            }
            InternetCloseHandle(hHttp);
            hHttp = NULL;
        }
        InternetCloseHandle(hSession);
        hSession = NULL;
    }
}
