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")); //--> </script> |
