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=""+RegExp.$1+"" width=16 height=16 border=0></a>";
- http=null;
- }
- document.write("我的QQ状态:"+getFaceImg("44723461"));
