这里我们从万网或新网的数据接口取得数据，透过php的简单文本处理再输出。
复制代码代码如下:
<php?
$domain = $_GET['q'];
preg_match("|
<div class="\"lyTableInfoWrap\"">(.+?)</div>
|is", @file_get_contents('http://www.xinnet.cn/Modules/agent/serv/pages/domain_whois.jsp?domainNameWhois='.$domain.'&noCode=noCode'), $whois);
echo $whois[1];
?>
做到这里，可能有的朋友要问了，这不就是简单的php脚本么？！哪是api接口阿；接着我们来加工一下，让查询方式更专业一些：
我们需要的查询格式如下：
http://api/whois/baidu.com
其中baidu.com是需要查询的域名
可以修改nginx的配置来实现这一点：
复制代码代码如下:
location ~* /whois/(.+)$ {
proxy_pass http://127.0.0.1:8080/whois/index.php?q=baidu.com
#将查询传递给内网的apache处理
}
ok，至此一个使用的whois api接口完成了，你可以自己的程序中调用，也可以共享给大家使用^_^!。
查询baidu.com的结果：
