How to join absolute and relative urls?

Question

I have two URLs:

url1 = "http://127.0.0.1/test1/test2/test3/test5.xml" url2 = "../../test4/test6.xml" 

How can I get the absolute url for url2?

Answer 1

You should use urlparse.urljoin :

 >>> import urlparse >>> urlparse.urljoin(url1, url2) 'http://127.0.0.1/test1/test4/test6.xml' 

With Python 3 (where urlparse is renamed urllib.parse ) you can use it like this:

 >>> import urllib.parse >>> urllib.parse.urljoin(url1, url2) 'http://127.0.0.1/test1/test4/test6.xml' 

Answer 2

 es = ['http://127.0.0.1', 'test1', 'test4', 'test6.xml'] base = '' map(lambda e: urlparse.urljoin(base, e), es) 

Answer 3

 >>> from urlparse import urljoin >>> url1 = "http://www.youtube.com/user/khanacademy" >>> url2 = "/user/khanacademy" >>> urljoin(url1, url2) 'http://www.youtube.com/user/khanacademy' 

Simple

Answer 4

If your relative path consists of several parts, you must join them separately, as urljoin will replace the relative path, not attach it. The easiest way to do this is to use posixpath .

 >>> import urllib.parse >>> import posixpath >>> url1 = "http://127.0.0.1" >>> url2 = "test1" >>> url3 = "test2" >>> url4 = "test3" >>> url5 = "test5.xml" >>> url_path = posixpath.join(url2, url3, url4, url5) >>> urllib.parse.urljoin(url1, url_path) 'http://127.0.0.1/test1/test2/test3/test5.xml'
