在Python中,我如何检查2个不同的链接是否实际指向同一页面？

Question

例如,这两个链接指向同一位置:

http://www.independent.co.uk/life-style/gadgets-and-tech/news/chinese-blamed-for-gmail-hacking-2292113.html

http://www.independent.co.uk/life-style/gadgets-and-tech/news/2292113.html

我如何在python中检查这个？

Answer 1

呼吁geturl()结果urllib2.urlopen().geturl()"返回检索到的资源的URL,通常用于确定是否遵循重定向."

例如:

#!/usr/bin/env python
# coding: utf-8

import urllib2

url1 = 'http://www.independent.co.uk/life-style/gadgets-and-tech/news/chinese-blamed-for-gmail-hacking-2292113.html'
url2 = 'http://www.independent.co.uk/life-style/gadgets-and-tech/news/2292113.html'

for url in [url1, url2]:
    result = urllib2.urlopen(url)
    print result.geturl()

输出是:

http://www.independent.co.uk/life-style/gadgets-and-tech/news/chinese-blamed-for-gmail-hacking-2292113.html
http://www.independent.co.uk/life-style/gadgets-and-tech/news/chinese-blamed-for-gmail-hacking-2292113.html
