asp.net 域名注册查询接口 支持批量后缀查询
需要用到域名查询的功能,网上查了一些资料,几乎都是ASP版的,而且功能有限,不能满足我的要求。
百度后,结合网上的例子,整理出了该功能!
asp.net 域名注册查询功能, 支持批量后缀查询!
要实现查询,首先要找到域名查询接口,这里我们使用的是万网的域名查询接口
WHOIS信息接口:
例如查询域名:tstmm.com
该网址返回的数据为XML格式:
[html]
<?xml version="1.0" encoding="gb2312"?>
<property>
<returncode>200</returncode>
<key>tstmm.com</key>
<original>210 : Domain name is available</original>
</property>
<?xml version="1.0" encoding="gb2312"?>
<property>
<returncode>200</returncode>
<key>tstmm.com</key>
<original>210 : Domain name is available</original>
</property>
返回 XML 结果说明:
returncode=200 表示接口返回成功
key=tstmm.com表示当前check的域名
original=210 : Domain name is available 表示域名可以注册
original=211 : Domain name is not available 表示域名已经注册
original=212 : Domain name is invalid 表示域名参数传输错误
所以我们通过分析original返的结果就可以知道该域名是否可以注册!
