你想知道某个站点的所有者是谁么？网络爬虫工具之WHOIS协议的使用

更多分享：http://www.catbro.cn

一、前言：

• 在爬取一些网站的时候，我们可能会关心其所有者是谁。因为像Google这些，我们最好把下载速度控制得更加保守一些，不然很容易我们的爬虫就会被封了哦。为了找到网站的所有者,我们可以使用WHOIS协议查询域名的注册者是谁。Pyton中有一个针对该协议的封 装库，其文档地址为https://pypi.python.org/pypi/python-whois，我们可以通过pip进行安装。

二、安装使用

• 1、执行pip3 install python-whois,如果你在Python2开发环境下，可以执行pip install python-whois

• 2、安装后我们来验证一下吧

    import whois
  
    print(whois.whois('baidu.com'))
  
    #执行结果
