Alexa接口
Alexa的XML API接口是：http://data.alexa.com/data?cli=10&url=%YOUR_URL%
如果想获取更多的数据可以用：http://data.alexa.com/data?cli=10&dat=snbamz&url=%YOUR_URL%
用http://data.alexa.com/data?cli=10&dat=snbamz&url=baidu.com返回的数据如下：
| <?xml version="1.0" encoding="UTF-8"?> | <ALEXA VER="0.9" URL="baidu.com/" HOME="0" AID="5ENjk1UlIcc1fJ" IDN="baidu.com/"> | <RLS PREFIX="http://" more="82"> | <RL HREF="21cn.com/" TITLE="21cn.com"/> | <RL HREF="163.com/" TITLE="网易"/> | <RL HREF="taobao.com/" TITLE="淘宝网"/> | <RL HREF="sohu.com/" TITLE="搜狐首页"/> | <RL HREF="sina.com.cn/" TITLE="新浪首页"/> | <RL HREF="qq.com/" TITLE="QQ.COM"/> | <RL HREF="people.com.cn/" TITLE="人民网"/> | <RL HREF="www.3721.com/" TITLE="网络实名"/> | <RL HREF="search.21cn.com/" TITLE="21cn_com - 搜索引擎"/> | <RL HREF="e.pku.edu.cn/" TITLE="天网中英文搜索"/> | </RLS> | <SD TITLE="A" FLAGS="DMOZ" HOST="baidu.com"> | <TITLE TEXT="Baidu.com"/> | <ADDR STREET="The Ideal International Bldg, 12th floor" CITY="Beijing 100080, " STATE="Beijing" ZIP="" COUNTRY="" /> | <CREATED DATE="11-Oct-1999" DAY="11" MONTH="10" YEAR="1999"/> | <PHONE NUMBER="+86 1082607100"/> | <OWNER NAME="2009 Baidu "/> | <EMAIL ADDR="baidu_dns_master@baidu.com"/> | <ALEXAPRO TIER="intro"/> | <LANG LEX="zh-CN"/> | <LINKSIN NUM="191219"/> | <SPEED TEXT="1517" PCT="56"/> | <REVIEWS AVG="4.0" NUM="98"/> | <CHILD SRATING="0"/> | </SD> | <KEYWORDS> | <KEYWORD VAL="Chinese Simplified"/> | </KEYWORDS><DMOZ> | <SITE BASE="baidu.com/" TITLE="Baidu.com" DESC="The leading Chinese language search engine, provides &quot;simple and reliable&quot; search experience, strong in Chinese language and multi-media content including MP3 music and movies, the first to offer WAP and PDA-based mobile search in China."> | <CATS> | <CAT ID="Top/World/Chinese_Simplified_CN/计算机/互联网络/搜寻/搜索引擎" TITLE="搜寻/搜索引擎" CID="254859"/> | </CATS> | </SITE> | </DMOZ> | <SD> | <POPULARITY URL="baidu.com/" TEXT="5" SOURCE="panel"/> | <REACH RANK="6"/> | <RANK DELTA="+0"/> | <COUNTRY CODE="CN" NAME="China" RANK="1"/> | </SD> | </ALEXA> |
其中POPULARITY元素中的TEXT属性的值5就是Alexa排名。
用PHP实现通过Alexa API 获取Alexa排名的代码为：
<php>
function getAlexaRank ($Domain){
$line = "";
$data = "";
$URL = "http://data.alexa.com/data/?cli=10&dat=snba&url=". $Domain ;
$fp = fopen ($URL ,"r");
if ($fp ){
while (!feof ($fp )){
$line = fgets ($fp );
$data .= $line ;
}
$p= xml_parser_create ();
xml_parse_into_struct ($p , $data , $vals );
xml_parser_free ($p );
for ($i =0 ;$i <count ($vals );$i ++){
if ($vals [$i ]["tag"]=="POPULARITY"){
return $vals [$i ]["attributes"]["TEXT"];
}
}
}
}
?>
<?php
echo getAlexaRank("baidu.com");
?>
