用asp实现QQ在线查询

编者(icech)按：这段程序的方法是利用XMLHTTP来读取腾讯网站的相应HTML代码获取QQ的头像，根据这个想法，我们还可以抓取很多其他网站的信息，如天气预报、新闻等等。

<script language="javascript"

<!--

function getFaceImg(QQcode)

{

var Re=new RegExp("^[1-9]{1}d+$","g");

if (!QQcode||!Re.test(QQcode)) return;

var URL="http://search.tencent.com/cgi-bin/friend/oicq_find?oicq_no="+QQcode;

var http=new ActiveXObject("Microsoft.XMLHTTP");

http.open("GET",URL,false,"","");

http.setRequestHeader("CONTENT-TYPE","text/html; Charset=gb2312");

http.send();

if (http.status!=200) return;

var webStr=http.responseText;

Re=new RegExp(""(http://img.tencent.com/face/[^"]+)"","ig");

if (Re.test(webStr))

return "<a href="http://search.tencent.com/cgi-bin/friend/user_show_info?ln="+QQcode+"" target=_blank title="QQ:"+QQcode+""<img src="http://img.tulaoshi.com/attachment/portal""+RegExp.$1+"" width=16 height=16 border=0

http=null;

}

document.write("我的QQ状态："+getFaceImg("44723461"));
